Oil seperator/ catch cans

[AlarmedBread]

I searched and didn't find much info on the subject.

Interested in what types people are running, how they've run the lines and what effect it has had on oil use.

In my case, I've got a tired old engine which has turned lord knows how many miles thats burning a bit of oil off throttle above 3k. I realize the best way to solve this would be a mild rebuild, but it's not leaking oil (knock on wood) so for the time being I'm considering installing a separator to see if that might help a bit.

Post up your setups/experiences please.

Burning oil on a trailing throttle sounds to me like valve seals. If that's the problem an oil separator won't help.

You can do a quick and dirty check to see if an oil separator would help. Disconnect the hose from the valve cover and plug it. Then connect a hose to the valve cover and route it into a good sized jug secured in a convenient spot in the engine bay, say a quart or more. For the test a quart milk jug tie wrapped in place should be fine.

Valve seals are easy to replace with the head on the car, just replace em!

Valve seals refers to the seats imo. Stem seals is what you are refering too yeah?

Last time I poked around the TB area, I noticed a good bit of oil residue which is why I thought a separator may be in order. I'd also been told at the last hpde by several members that they thought it was piston ring blow by (apparently a common problem?) causing the puffs of oil smoke and as such have been budgeting for a rebuild at some point.

Thanks for the tip guys, I'll replace the seals during the next valve adjustment.

While the valve seals can be replaced with the head in the car, by the time the seals are worn to the point that they are leaking the head usually is in need of a general refresh. My approach would be to pull the head and have it worked over.
