Hello people.... im sort of stuck on this one!!!!! i have a 2.5 sti with 62k on the clock and when accelerating through the gears hard every now and then i can hear and feel a slight clutch slip? but when i accelerate hard from standing its fine? it has an API heavy duty clutch and light flywheel with less than 15 k on them..... i use the car now and then but never to the extreme of launching it,but my partner uses it every day and has never noticed it? now unless she tracks it with out telling me i thought it should last longer than 18months.... it seems to be at above 60mph
thanks.

 

the cars running just ove 300 bhp

 

When my clutch went (95 WRX with around 260bhp) it went from a slight slip to being almost undriveable in around 20 miles.
I guess a small oil leak could also cause the symptoms that you're seeing (maybe rear crank seal?) any oil usage?

 

Mine was like that only slipping now and again turned out to be the clutch gone

 

It uses just under 1 litre for every 10.000 miles which i thought was ok for the 2.5? maybe not,i take it if the crank seals weeping that this would be the symtoms?

 

Amego,how long before it was undrivable? or did you not let it get to that stage?

 

Didn't let it go that far

 

Spoken to a couple of people today and they both said it could be in the map? so im seeinging jgm next thursday to see? FINGERS CROSSED
