okay now I might have to take the idea of the trubo off my mind.. car is fully running like its on 4 cylinders of somethign the whole thing vibrates when idling and sounds like a wrx under acceleration.. guess Ill just have to see what my mechanic says tomoz :D

Update: Mechanic reckons is runnign on 5 maybe 4 cylinders.. he told me to check plugs (i've replaced them), check the fuel return to the furl tank as in might have been blocked and flooding the engine (which I've done runs fine), then he said ignition module (swapped this with my mates made no difference) next up is coil packs, and if not those maybe a blown gasket between the cylinders.. any other suggestions..

Alright I think i've discovered the problem.. I replaced the whole ignition system with that of my mates r33 so I knwo it works fine.. I then proceeded to unplug each coilpack lead one at a time.. as expected the idle changed slightly.. however when I got to the 5th cylinder and unplugged in no change.. im guess this means a problem in cylinder 5..and according to the above problems I'm think maybe a bent valve or valve spring etc.. does that sound possible??

Yes............ Or a crack through the piston ring land.

But unplugging the coil pack on that cylinder still should have made a differance. Maybe the coil pack is faulty or even the loom from the module to the coil pack. Try and swap the loom from your mate's car.

PS: Make sure you have the same series engine (ie: S1 coil packs will not work in S2 engines and vis-versa)

Have you done a compression test yet.

hey guys my turbo i think, makes a noise like this RRREEEEEEEEEE lol, under load, hi revs..

i think its standard 32 but i could be wrong, still ceramic an all..

um and 15psi gets put threw it every day..

goodnight turbo?

fan belt stretchin under load?

how long left till turbo dies?

can i screw the engine if i keep it up?

sorry to hijack...

thanks chris

Yea my turbo makes same noise u mean like a winding noise, its could be the bearings and such when i got my car serviced my mechanic which is benno from racepace called up and said that turbo makeing winding noise and could be on its way, he suggested not to do a dyno because it could blow up then and it could not said should get new one befor i do a dyno, as for how long i dont know i geuss it depends how you drive the skyline and if you use it allot.

Definately nothing in cyclinder 5 and we swapped everything between the two cars.. igntion module, loom, coilpack the lot..I pulled the plugs and plug number 5 had a build up of what looked like oil on it (keeping in mind brand new plugs were fitted yesterday) I also noticed when shining a torch through the plug hole a build up of black sludgy gunk on the top of the head (or whatever ya wanna refer to it as) in both cylinder 4 and 5.. the rest were absolutely clean (i could see bare metal)

Update: Looks like a gasket, between cylinder 4 and 5...umm water coming out the exhaust, umm cylinders missing.. and when you rev it coolant comes out the radiator cap rather than runs away from it.. if that makes sense..

eh and got the compression test shit here so will do one tomoz for confirmation a head gasket doesnt worry me as much as engine damage.. im going to europe for 2motnhs shortly and my bro is a mechanic so he ca do his work while I'm away :D

It defiantly sounds like the common symptoms of a head gasket. My mate just got himself a subaru rs wagon and he has all the same problems as what your having, exept in his case oil has forced its way down his heater hose and is now filling his floor with oil and coolent lol.

    • The attached document is fine. I just downloaded & opened it.
    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
