Don't expect to catch anything. But that's a good thing! Mine's been on about 2 years and has the slightest brown misting inside

That is nice, wait until you start pumping out 28psi or so, mine will get about a 1/4 qt every month or so...

It all depends on how tight the motor is

Plus its nice to keep any oil out of the ic and delivery pipes.

It'll be the low pressure at altitude pulling the oil out of the engine

Maybe not, but John did not himself mention altitude in this one.

A word of caution about catch cans - one of the causes of sludge on the T7 engine was the poor venting ability of the early breather. This kind of setup will seriously reduce the gasflow out of the crank case. The stock T5 system is very efficient - the large pipe has suction as the intake air moves across it's opening in the intake hose and the small pipe has manifold vac. Both these together pull the gases out of the crank case in all conditions - with this setup you loose a major component and one that works when you most need it. Actualy it goes further and creates an obstruction . Most oil in the intake is from the turbo bearings anyway and you can't stop it. Only very high boosting engines throw oil from the crank case and then it's still an insignificant amount as a proportion of intake air - even .25qt per month.

Default Good point...

I peak at around 27psi and level off to 22 or 23... I haven't put many miles on this catch can set up but from what you said...I wonder if I basically had it in line with the original hard line... (route the line to the small filter back to the now plugged line)... would the can still catch the oil or would the vacuum on it from the original line defeat the purpose and suck the oil up as it's going into the can..?

It would be much better as an inline divice as you won't loose the intake suction. It will probably catch more oil as there will be more blowby going through it as a result of this.

Put it somewhere on the intake - should be worth .000001hp with the extra airflow
