What are you using for a vacuum source on the cans?


Regardless of blowby, a lot of oil splatter is happening in the valve covers. You want negative pressure in your crank case (testing has shown it actually helps with ring sealing), so you need to suck from somewhere. Valve covers make the most sense.

Remember road tubes on older sbc? lol..

JAZ mini catch can with filter on top on my pass valve cover as well with no issues. It hasn't pushed any oil into it that Ive noticed under boost (none has drained out). But I get some oil in the separator that I dump out every month (just an ounce or two).

Alot can be said of newer engines in need of things that Kingtalon would comment about being incorrect. My stock 5.7 HEMI in my 14 and 18 RAMs have horrendous PCV systems which leads back to piston rings and blowby. The stock PCV system sucks up so much oil into the intake in a short amount of time its insane. They also in stock form run the PCV line back to the filter box which allows oil to be sucked through the entire intake tube (sensors and all), Gum up the TB and intake. I also have a Diablo oil/air separator on my 5.7 HEMI and I literally have to dump out 4+ ounces of oil from it in a months time (less than 500 miles a month). Its actually normal according to Chrysler that the engines loose 2qts of oil in a normal 5k oil change schedule. Again this is NORMAL for these engines even if we dont like it an are not used to it.

Increased ring gaps for BOOST/N20 will cause added blow by and increase the oil wanting to come out of the crank case vapors resulting in a mess if you dont contain it. Nothing wrong with catch cans/oil air separators on these motors.
Probably 80% of the volvo 3.0T and 3.2 engines use about a quart every 1K. sometimes more. couple of times per week we get people in "my low oil lights on, volvo said i can go 10K on oil changes" Whoops.

Re: Going from a single turbo to twins


Well, the new camshaft is in, new timing cover and valve covers. I sold the HSR and bought a new intake and throttle body. I am slowly putting this back together again.

haha, gotta love the OE manufactures. I run extra oil knowing I'm going to loose a bit through the separator.
