Hi

just wondering what are all the factors that can cause blow by. Mate has a plenum installed and on the breather on top of the engine ( the front one) he has a small filter and there seems to be excess oil around the area. should a catch can be installed?? will that reduce blow by?

Even an engine with normal wear and in normal operating conditions will still produce positive crankcase pressures that can also blow a bit of oil especially if the filter is stuck directly to the breather it will be evident more so than accumulating in the intake system. So may not necessarily be 'blow by' as such.
