slipping clutch....
Posted: Sun Mar 02, 2008 9:00 am
Hi guys.
Got my SD1 out on the road doing some road tests after the rebuild. Background in a nutshell
removed 3.5 motor and auto and in went a 3.9, performance road cam, ported heads, 4 barrel carb, headers etc etc and now a manual using an LT77 gearbox.
anyway I was blasting (literally) up and down the hill today (ha ha ha) when suddenly the clutch started slipping. it got pretty bad and i just made it up the hill to the safety of my house.
Now there was no burning smell which I thought one would often get. infact no clutch smell at all.
Once home i looked to find an oil leak from "somewhere in the engine bay" and this was runnig along the sump rim and dripping down the dust cover on the bellhousing.
The dust cover is not tight against the bellhousing due to some modifications and is awaiting replacement.
Anyway i have no idea why this happened.
two theory's
a: too much HP now going through the clutch (the parts used were new rover parts and inspected by two mechanics before installing)
b: oil has dripped onto the clutch thus the loss of trackion and no smell.
Im lost and really dont want to be removing the motor so I thought to fix the oil leak first, then try road testing again to see if my b: theory was correct.
any idea's?

) and found out that the pivot pin needs no washer behoind it . My "helping neighbour" had put a big ass spring washer behind the pivot pin! This xtra 4mm has cause my clutch to not quite grip properly.
