will remove oil gallery plugs and frost plugs
The block will be getting a nice hot bath of degreaser/hot water over the weekend in 200 litres steel drum and large gas burner under it and heat it overnight to get it boiling away
should get rid of oil and grime on inside of block and clean passages out to be sure
then use gurney to clean and dry then WD40, then see what it looks like
No rocker leak on mine.
Rear main leaks (I would say this is my fault from before install of the engine - we live and learn)
And oil pump to block gasket leaks. But clearly can't use it twice after re-packaging the pump when it dropped oil pressure early on in engine life.
not sure whether the hyd cam and lifters have been changed earlier as it had chilled iron lifters in there and according to crow cams yesterday they were NOT standard in holden although I could of misunderstood the statement
