... so where's the best place to get one of them "Go Faster" oil catch tanks ?

Sitting on tut fence here.... and not wishing to get into the semantics of "blow-by" ... are you not both correct, in that the normal definition for blow-by is indeed caused as cantfind1 says, and who will argue with wiki ! ... but on the other hand, as Gorilla alludes to, said gases as a result of the nature of the engine plumbing could also blow by the valve stem seals

... feel the love

Oh yeah ... @ Ian aka Yanto ... love that post, where did you find the 4 hours to put that together mate ????

Hi,

Extract -

''13. Worn Valve Stems and Guides
When wear has taken place on valve stems and valve guides, the vacuum in the intake manifold will draw oil and oil vapor between the intake valve stems and guides, into the intake manifold and then into the cylinder where it will be burned. If this condition is not corrected when new piston rings are installed, an engine is likely to use more oil than it did before because the new piston rings will increase the vacuum in the intake manifold. When gum or deposits on the valve stems are removed – a procedure recommended when overhauling an engine – the seal previously formed will be removed and leakage will be more pronounced. This is particularly true on overhead valve engines where loss of oil may occur on the exhaust valves as well as on the intake valves. High oil consumption caused by too much valve guide clearance can frequently be cured by reaming or nerraling the valve stem. In some cases new valves may also be required. Use of a permanently bonded valve stem seal will give added insurance against oil leakage on complete engine overhauls or on valve jobs.

Cantfind1- have a read you might learn something.

Might also explain why you have oil contamination in
your CSL Plenum and I do not.

Regards,

The Gorilla.

Yeah but which is best?

Blow By the piston rings OR Blow By the Valve stems??????

There's only one way to find out

Is there vacuum in a Csl carbon air box?
