Hey guys,

I was wondering if any of you guys who have previously done the +T conversion can help me clarify a few things. I'm currently in the process of doing the conversion but I just needed some answers in regards to the oil return line.

Initially my plan was to use a T-piece into the VCT oil return line but after doing a dummy fit, I was told, and by looking at the fact that the engine mount is in the way, that it is a prick to try and get the line from the turbo to the VCT.

So now I think the last resort is to tap into the block, however I have a few questions. What did you guys do in the regards to the metal filings? Did you take out the sump out? Is it possible to take the sump out in an R33 without lifiting the engine? or Did you take any other particular measures to get rid of the filings? or Is it pretty safe to do so without the filings having much effect?

Anyways, thanks for your time and help. I appreciate it,

Rian

You definitely want to take the filings out...

I havn't done a RBDE+T conversion, but from my own conversion, and searching around, i think RBs have a oil port already on the block that's there from the turbo variants, should be able to just use that.

But if not, you'll have to drill and tap a spot ABOVE the level of oil when full, and yeah you'll have to have it up on jack stands at least, a hoist would be better, and the engine out would be even better!

It's a bit of a job, cos the sump needs to come off, and you'll need to reseal it too.

Speaking from someone who has an oil leak from the same very part were talking about, I'd recommend getting a workshop to do it for ya. That's if there isn't a pre tapped spot on the block already. Another skyliner will be able to confirm this for ya.

Good luck!

Thanks for the quick reply mate, but can you clarify if I need the engine out or lifted to get the sump out? Because it seems that I could most likely get the sump out by removing the sway bar and sliding it forward, but I'm not 100% sure if it would hit the pickup while trying to remove sump.

Cheers,

Rian

lol wtf??? engine out???

nein.

first of all how the hell did u get filings in there???

here's what i did. rip everything i needed that would be in the way - out of the way

called a pirtek / enzed guy

he fitted the lines up and everything for about 300 bucks

dont stuff around ripping out engines n stuff

mind you this was on a 2 litre not 2.5

Well if I drill a hole into the block for the oil return, wouldn't some of the filings go into the block? Mind you I will be vacumming while drilling so that the majority of the filings will be out, but wouldn't some of it still fall into the sump?

But you gave me an idea because I might get the pirtek/enzed guy to come around and see if maybe he can work out something easy to get the initial idea of having the oil return into the VCT working. Cheers.

dude... the oil return lines and everything are already on the block!

they're just "tapped off"

also

not that this matters if you're paranoid about it... but think about a drill... think of the "tread" pattern

the filings go "out" not "in"

just drill carefully

but yes

pay a pirtek / enzed monkey to do it. don't make your hair go grey with this crap. they supply n fit everything while you go inside n drink a pepsi max.

Sorry for the huge image size

BLOCK

That is the picture of my block. As you can see in the bottom left-mid, all I have is an outline of a red marking for where the stock oil return would be. If that is the meaning of "tapped off" then I'm sorry I might have misunderstood the term.

I understand that some/maybe all other RB25DE have a bung for the oil return, but that red-ish marking is all I have.

But yeh, I'll most likely end up getting the Pirtek/Enzed guy to do it. Thanks for that advice, seriously was worried for a sec because I wasn't quite sure how I should go about it.

PS: I can't sleep. Not stressed out, but I'm also not at peace with this whole thing until you made me feel warm and fuzzy :) lol

Ohh btw, still haven't answered my question about whether taking the sump out is possible or not in the R33 without taking out the engine. Because as turbo x-trail pointed out, I might still have to clean the sump. or did you pretty much not bother with that Mr Eps?

you might get away with it, but personally, I wouldn't risk it. Besides, you ought not have any filings as such in The sump, but there will def be burred edges on the hole that you'd wanna clean up, plus, tapping the hole can cause more filings too. Up to you though. If you have a decent oil filter and/or a magnetic sump plug, and providing you're careful, it migh be ok.

Good luck finding a mechanic that would tap the block without pulling the engine out. My mechanic t-pieced the oil feed of the pressure switch iirc.. they didn't want to risk tapping the block without taking the engine out.

I'm not sure on whether you can remove the sump without the engine coming out.. i'm sure if that were possible my mechanic would have done that? I doubt there's that much difference in that respect between an R33 and R34.

From what I understood, the oil return on the R33 block had a blanking bolt and only the R34 had a provision for where it "would" be on a DET...

I THINK Dori's engine had the bolt though? Anyways, I'll leave it to a couple of the R33 guys to give their advice on how they handled the oil return on the RB25DE but it's best not to risk just tapping the block without pulling the engine.

So if they didn't tap out your block and you didn't have the blanking bolt, what did you end up using for the oil return?

I think I'll get Pirtek to come around and see if they can sort something out with T-piecing into the VCT. I know that T-piecing into the VCT would be the most suitable solution, but I have just been told that it's a prick of a job, but doable. So since they'll be doing it, they'll probably make something custom to make it easier.

If I were to end up tapping into the engine as a last case scenario, I would definately be taking as much precaution as possible. Probably use a magnetic sump plug, magnetic oil filters (change every 500km or something for the first few weeks) and flush the engine with some shit oil and end up changing the oil every 2500km until probably 10000km or there is no longer any signs of metal. I know it ends up being pricey, but I guess it's better than taking the engine out.

Ok, have done what your asking.... however, I dont think I am going to be the best of help....

I did not know much about my car back when it got turboed, I did some of the stuff myself, but they guys who did the oil feed/return line dont exist anymore. I dont know if they took the engine out or not to tap the lines, however I can say that I dont think they just had a simple bung in and they pulled it out.

Ill try to get some pics for you by the end of the day.

Also, my return line is not into my sump.. its at the bottom of the block.

Some pictures would be excellent mate! Would help me a ton.

Yeh I'm not going to tap into the sump, I'm tapping into the block just above the sump if I end up taking that route.

But anywho I would be really grateful if you can get the pictures!

Appeciate it.

Quoting Dori:

oil feed; ran a braided line to oil pressure side & tee'd into that

oil return: on the r34 de, theres blank mark but with r33 there shud be a bolt which u can remove.

however on the r34 de theres the vct return which is a blanking bolt so i used that.

*end quote*

That's for an R34 but may be similar?

He's talking about oil drain mate, not feed.'

You shouldn't need to take the engine out unless there's something in the way. Just need the sump pan off then drill/tap/de-burr/clean away. seal it back up and fill him back up with oil.

I see.. I'll be honest when it comes to oil feeds/drains etc.. i'm not so knowledgeable, pretty much relying on what I can recall from my conversion.

ps. nice X-Trail, the build link in your sig doesn't seem to be working though :P

Yeh for the oil pressure I'm pretty set: T-piece into the oil pressure sensor and run a braided line from that, behind the block, and to the turbo.

As for the VCT, that's interesting that the R34 have a blanking bolt instead. Doesn't it run VCT anymore or something? But it's good to know that you guys have had no problem with going into the VCT.

The problem on a skyline is that the sump is a one piece, ie there is no sump pan per se. Thus, I've been told, it makes it impossible to try to remove the sump without taking out the engine because the oil pickup gets in the way. Unless I want to lift the engine a few cms and probably can just make it, but I don't know how much piping and shit I have to take off.

But what do you guys think about my earlier plan to try and get the filing out by other means such as magnetic oil filters with more frequent change, magnetic sump plug, and more frequent oil change? Do you rkon that will stop all the filing from getting through or am I missing something important?

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
