Hows It?

[russstuff]

hey all..

figured it was time to join in all the fun and get some answers at the same time..

i bought a R33 gtst with a RB30/25 pushing 349.6 rwkw with a screamer pipe and holy hell i'm in love !!

only problem is i gave it to some monkey with a spanner not long after i got it and mow the engine is F.U.B.A.R.

so hopefully while i'm here i can pick up a new engine for her.

see you around the forums

cheers

hi welcome to sau!

what the hell happened to your motor? i have dealt with bad mechanics before, and you end up paying for everything twice, having to undo all their bad work. very painful.

good luck with it.

The day i purchased the car i noticed a slight big end bearing knock i was too blown away by the power and noise of this thing that i didnt pay attention to the finer details.... my bad!

but in the sale i knew the box was going to have to come out anyway and get new 3rd &4th syncros.

after getting the car back from the mechanics i complained about lumpy/slow gear changes and was told that "your running a car with this much power its going to have problems, they werent designed for this" in less than a month of getting the car back from the mechanics the big end noise came back, the crank was pulled again and something had been pushing the crank forward and it made a 1.5mm groove in the thrust face on the crank, that metal has gone on to destroy the oil pump, pistons, bores and i suspect cams.. (i havent seen inside the head yet) about a week after getting the car back i had also found loads of metal in the gearbox so i suspect something they did in the box caused the problem in the engine.

but the mechanics response was "build your case and tow your piece of s*^t car out of my workshop"

this is the short version of the events but bretty much how it went down.

its got a big clutch hey

[bozodos]

kill the mechanic then yourself

[russstuff]

not too big a clutch, its got the nismo twin plate copper mix..

i've arranged for an engineer now to come out and do a report on the engine and box, hopefully he can find the answer... even if its not the mechanics fault i need to know what the problem was cause i sure as hell cant afford to do this too often.

bozo, i'm not sure that by killing the mechanic then myself will find the problem.....?

it might make you feel better

the engine sounds like it was fucked before you bought it, and not really the mechanics fault. they may have made it screw up faster. it had a knock before you took it in to be fixed. big end knocks don't go away by themselves. they usually result in the piston deciding that it doesn't want to be part of the crowd just going up and down all the time and that it is going to try going sideways out the side of the block to see what happens.

anywho, welcome to the forums

spose its true what you say mad082 but the original noise was so faint that half the mechanics i went to said the whole engine had to get pulled down to find the noise. i was a mechanic, so as soon as i heard the noise i knew what it was, honestly it was so faint you could only just hear it and only above 2800rpm on a light throttle. after removing the crank it was sent away, machined crack tested and the mechanics told me they plastiguage'd it on installation to check bearing crush and said it was fine. the problem this time is not that the big ends went again (although the noise is what made me take the car back) its the fact that something has been pushing the crank forward with so much force that the thrust bearing and face's wore so badly the metal went through the engine which i expect is what chopped out the replacement bearings...
