Hi guys,
Had a lot of oil through the intake of my RB25DET lately so on Saturday I picked up a compression gauge and slowly cried on the inside six times over
Basically 1,2,3,5 were 118-120 and 4,6 were 80&90, a wet test brought compression up by 50-60 on all cylinders.
So, If i crack the engine and drop in some forged pistons what else should I look at replacing/upgrading, any valves etc? Pistons, head machined, head gasket are pretty much on my list so far.
Also what causes the rings to go, excess heat/age?
At the moment I'm still pricing up a few options so any input is appreciated.
Cheers,
Nick.
