I brought a R33 GTR about two months ago. I noticed the A/C belt shredding so I got a leaver and pried the crank pulley back and foward and noticed alot of crank end float.
I had the motor stripped to notice crank thrust bearings have been half worn on one side only as well as a couple of spun main bearings.
Car made 450kw on 28 psi on e85 but the oil catch can used to fill up with oil and water every 1500kms
Motor was built about 10000 kms ago
Oil pump: Tomei
Sump: standard
Clutch: twin plate exedy
Oil return line from head to sump.
Need help what could have caused the problem and what mods to do this time to ensure this does not happen again.
Thanks guys
