I bought the matic-J oil the other day was gonna do it myself today.. from the info i have found dropping the oil out the drain plug will only remove half then i can just top back up the exact amount i removed.

Or should i take it to a mech and get them to flush and fill with full amount??

im only asking coz i found mixed results, some saying not good to flush the system(unwanted pressure..etc) and others saying not good to just drain as your not removing all the old stuff..

I just want to know what others have done.

either way im happy to do myself, or take to mech as i have bought the expensive stuff.... matic-J is like the cost of liquid gold. :ermm::)

thanks

sorry to start new thread.. but the M35 info one is getting massive and without categories gets hard to find stuff..

This is for S1 but pretty sure M35 is the same (i.e. the sump will hold a lot less than half). You could do it without dropping the sump. This way you are just using the stock auto's pump (it has been suggested that the pwer flushing system of the auto shops can damage seals but I can't verify that):

Get yourself an auto sump gasket kit and a 20L drum of (ideally) quality synthetic atf. You need 12 to 14L for the auto and you can use the rest for your attessa and power steering. Drain the sump and drop it (easier said then done - you will have to support the box and remove the rear mounting). You will only get betweeen 1 and 2 litres this way. Check that the new internal filter is exactly the same (otherwise the sump won't go back on) and if not either modify the new one to suit or clean the old one and put it back. Put 2L of fresh oil down the dip stick tube.

Then pull a hose off the trans oil cooler and run the engine until you have pumped out 2L into a container. Pour 2L of new oil down the dipstick tube and repeat until you get clean oil coming out. This will take 12 to 14L in total.

You should be able to get quite a lot by draining (about 4L or so), unfortunately ours takes over 8L, so you could do it again the following weekend which is effectively just diluting the old oil with fresh stuff or alternatively take it to Nissan for a transmission flush and take the price of the oil off the bill (you will lose $$ though).

hmmm.... while I think about it, would something like the Liquivac work for removing all the transmission oil?

matic-J is like the cost of liquid gold. :D:(

Maybe look at getting some Matic-S from the US? We have yet to receive it in Australia, but it is the 100% synthetic replacement to Matic-J.

Agreed.....

couldnt agree more with another forum for m35 stuff.

I keep confusing peoples comments about S1's and S2's until i notice either C34 in their list of cars or their avatar of a c34.. and im like meh doesnt apply to my s1!

    • 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.
