R34gtt Neo Engine Problems

[R34-2NV]

has anyone ever heard of a fairly stock neo turbo engine needing a rebuild a few months after a new clutch being installed.

I only a few months ago put a nismo coppermix clutch into my skyline gtt neo and a few weeks after the clutch was installed i could hear weird clonking and clicking noises whenever i applied the clutch.

a couple months later and the mechanic who installed it is telling me that my engine bearings are gone and my engine would need a rebuild due to the stress caused on it from the spun bearings.

before the clutch was installed there was not one odd sound out of the engine or gearbox and the car always drove like a dream.

I always service it with good synthetic oil quite regularly and check to make sure everything is good.

In my last service which was a couple weeks after the new clutch was installed i found little metal pieces in the oil which i have never seen before (and I always check the oil for anything unusual).

Can a clutch not installed right cause this to the engine? or could the oil pump have been clogged from these little metal pieces that would have come from the clutch, as when the clutch was taken out to be inspected it was heavily worn and only after a couple of months.

I never take it to the track or thrash it. its a weekend car and i baby it all the time.

I need help with this because im finding it hard to trust my mechanic anymore especially considering that i get all mu tuning done there and it would be reasonable to say that if then engine was on its way out due to a fault he would pick it up on a dyno check which i have done a few times.

more than likely the clutch being installed has nothing to do with the engine letting go.

the clutch itself may have indirectly have something to do with it, but again, it would have only brought to light a problem that already existed. if you went a heavier duty clutch and then even just a few times did a few silly things then the extra stress from the clutch grapping much better could've been enough to be the final nail in the coffin for the engine. or it could have nothing to do with it and it is all just coincidence.

yeh fair enough, i think the oil pump may have had something to do with it though, i probably should have upgraded it after the clutch was put in. I honestly dont do anything stupid with this car, the odd hit here and there but im not really a burnout person (not in this car anyway). either way new engine must be put in because rebuild just cost too much these days. Labour being the most expensive part!!!

mate ide get another mechanic to have a look at it.

you said you hear the clunking noises when u apply the clutch which leads me to believe that it just may be the pucks/plates in the clutch rattling.

get another opinion and keep us posted

good luck

i was going to say the same thing, but then i saw that he said there was metal filings in the oil

starting it in gear with un uprated clutch could have something to do with it

I'm confused how you think pieces from the clutch would get inside the engine / oil system?
