Hi everyone,
O.k here we go
1990 GTR R32 RB26DETT only mods are air pods.
115000klms
1.Blown head gasket
2.water on turbine caused it to crack & break off
Basically i was driving along in top gear approx 110klm/h when the engine shutdown & heaps of white smoke was coming out the exhaust.Got a tow home & started to dismantle found the rear turbo had lost the turbine wheel completely & that cylinder 5 was wet (blown headgasket),removed engine to find the head gasket was blown badly on 5 ,but the bores of 4,5,6 were all o.k. no scratches or scores from the turbine ceramic.Also to both mine & my fathers amazement the oil pump had three screws undone by approx 2-3 turns ,enough to be visible to the naked eye.That was not the worst of it, found the front diff to have between .15mm-.36mm backlash & the crownwheel was floating & not pre-loaded!
Diff doesn't appear to have been dismantled before.was able to setup diff to the specs in the manual for backlash & pre-load's after changing some shims.
Has anyone else come across this with the front diff?
Also a big thanks to wrxhoon for the advice on the engine removal u were right on saved me a heap of time & managed to break nothing.
