Well long story short,
My step father is putting an RB30E+T into his EH holden,
Long process, finally got it going, took it for a bit of a drive to set the boost controller...
Pulled up to check where the tyres were rubbing, and noticed a miss, took it back to the house... did all the normal checks, couldn't find anything...
Next day my step father checked it over and found milky oil on the dipstick and in the rocker covers,
Did a compression test 140psi on 1,2,4,5 and about 125 on the 3 and 6
Motor was rebuilt about 10 years ago and done bugger all K's since, was in another EH that was a weekender...
What's do u's reckons wrong?? we're in the process of removing the head as we're leaning toward head gasket...
