Hi all,

Just noticed a problem my r33 gtst, running 12psi, front mount, exhaust, turbosmart bov, is blowing a shit load of white smoke when im into it.

It looks really bright white like tyre smoke and it keeps coming out for a bit after you give it a bit..

Any ideas guys, i have searched but cant find a straight answer.

Thanks

Check your cam cover breathers/catch can breather to make sure they aren't kinked. Check the turbo oil drain to make sure it is not kinked.

If these are all ok and not blocked, then yeah....turbo is likely to be stuffed

Ok ill check them out this arvo, i cant understand how the turbo could be stuffed, it still feels as if it is running fine, just blowing smoke.

is it sounding lumpy or off beat at low rpm like idle?

do a compresion check :/

mine was blowing white smoke thought it was a turbo but really it was loss of comp in 6.Turbos are fine..................

new bottom end for me!

Hey guys I'm having the same sort of problem, I just recently swapped my commodore for a r33 and it will only blow smoke when it starts to come on boost, I had a quick look over the engine to see any problems and there was a kinked hose coming out the top which seemed to be a breather line of some sort? I fixed that and noticed there's oil all over my engine, turbo etc so I'll be degreasing that tomorrow and cleaning out the intercooler and pipes as there's oil in them. Hopefully this will tell me wether it's just the turbo or something major :/. Any other idea's? Also it's running rough as thought it has a lumpy cam, I've read a fair few posts on here about pcv valves and stem seals etc but how can I check these? I've got a mechanic coming to check it out tomorrow, compression test etc but his never worked on an rb before and just a bit nervous he won't know what his doing. Any opinions will be much appreciated thanks guys.

Hey guys finally got enough time to do my compression test, done cold test first, WOT, all plugs removed , 8 reps of the engine each time each got tested twice,

Results from intercooler to cab

Gunna do a hot test then a wet test but at the current moment it's pretty obvious my engines gone to limiter heaven, any suggestions on simple ways to get back in the road? It's jump a simple daily drifter so don't want to fork out thousands just yet..

I assume your head would be totally rooted and possibly piston ring lands broken which won't necessarily be visible until you pull them out.

The fact you just asked if the cam gears can be salvaged means you should just get another cheap engine and throw it in. Don't bother pulling things apart and confusing yourself.

those parts can be salvaged. you might even find the engine can be fixed....its not all doom and gloom...but pull the head and check for what is stuffed.....no use worrying about it until you pull it down and find out what you need to fix/replace/machine.

if you have a mate that has an inspection camera you could poke it down the spark plug hole and have a look also...if you are lazy :)

i've seen some major damage in stock car motors that has been fixed.

Just swap it out for a cheap wrecker motor, get one that has a comp test and leak down test etc done so you know its in good nick then drop it in and off you go

Then pull yours down and rebuild forged or even 3ltr :D at your own leisure when you have decided its now to slow and you want more power

It happens to all of us at some point :P

considering the demand for these motors....finding a cheap wrecker motor even a cheap one is going to set you back near $1500-$2000. if he has only damaged the ring lands and not the bore he could just be up for a piston and rings....this is unlikely...but still possible...have a look....take some pics and report back...interesting that it wasn't cyl 1 or 6 that let go.

    • 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.
