What do i look out for

[GWtaylor]

Thanks a lot mate I'll keep all that in mind

check the engine for excessive rocker/crankcase pressure. remove oil cap while engine is at idle. it should not drop more than 150/200rpm

What does this test is for?

Worn piston rings

[datdrift]

as we are on the subject is there any advantage of fitting a crankcase breather filter on the rocker cover, and blanking off where it goes to the intake duct, or is it better left as it is????

[adzs12]

It is beneficial but it will idle like a dog if your rings are worn

[datdrift]

well ive pulled the oil cap off with it running before and it doesent seem to blow out too much, dident notice it change the idle either, its done 98K and seems alright i'll get one if theres one on ebay cheap
