Engine Seals On Gtr's

[Fat-magz]

just wondering...

ive been told that the engine seals start to wear out on the GTR motor's at around 100-150,000km's is this true? and how can you prevent this or what happens when this occurs....does this mean a whole new rebuild?

cheers

P.S this might be a load of shit i dunno....just heard it from a few people one of the guys owns a FD series 8 rx-7 though( could be abit one eyed)

Sounds like a myth, it's a racing engine afterall not a taxi engine.. about 150,000km you are probably looking at a rebuild anyway, though only if compression is below certain limits for that specific engine (rb20, rb25, rb30 etc are all different)

the R32 service manual for the RB26DETT specifies the cylinder compression lower limit as 121psi, with no more than 14psi difference between adjoining cylinders.

Front crank seal started to leak on my r33GTR eng a few years back, pulled balancer off and changed it in situ. No more leak. Rear seal was still good.

My 33 RB26 eng comp tested with stock cams at 155-160psi.
