At the track. First 5 laps great.

Blew some oil out mighty mouse catch can, then started smoking out exhaust. Car was still running great I didn't even notice until they waved me off the track.

Looks like it blew a little oil out of the catch can. No blow by from either side of the engine, oil pressure good. No oil in coolant or anything else. Still seems to run great just a little white smoke that smells just a little like oil.

Any ideas for a quick fix before I pack it in?

I've been stalker watching your thread but it's unfortunate it didn't gain traction. I'm curious on the outcome here. I will be doing a Procharger and MM Catch Can system as well. I've read mixed reviews on its effectiveness and how it's supposed to be set up on a supercharged engine.

From your issues with the can, it almost sounds like the can is seeing boost. From what I've read, that's an absolute no-no I thought? Saw a video from RPM showing a MM catch can setup on a procharged car that had the vacuum side of the can plugged into the intake manifold. Guy was throwing all kinds of shame at it talking about "What do you think is going to happen when the manifold goes from vacuum to positive pressure?" They installed a check valve in-line between the can and the manifold. IMO, this is only a bandaide fix for that guys car, though. The crankcase still needs to be under vacuum, at all times. If the crank case isn't vented, bad shit will happen. Worse, if positive atmosphere builds in the crank case, it will push against the weakest seal. Front crank? Rear main? Blowby? Whichever relieves the pressure easier. Not to mention gases and condensation that needs to be evacuated.

I'm not an expert on the subject, but I think plugging that vacuum side of the can into the blower intake is the way to go, at least it should be a constant vacuum. If MM can is worth a shit, it won't fail to capture oil vapor as it's designed to, and you won't have a mess in the inlet. I'll be thoroughly upset if their expensive setup can't catch oil, lol. Just my thoughts on it.

As far as your exhaust smoke. Smoke is more or less color coded. White = Water/Coolant, Blue = Oil, Black = Fuel. If you're getting white smoke, pay attention to coolant levels. You don't have to have cross-contamination to be burning coolant or oil. If there's a hairline crack in the head or block, or a head gasket leak, it will suck it into the combustion chamber and burn it up. You can scope the combustion chamber and look at the tops of the pistons. If any of them look steam cleaned, you may have an issue. Look at the plugs as well. Not positive it would clean the plugs to the same effect, but plugs tell us a lot. Are the perfectly normal, one or two out of place from the rest, super black, burned, or wet with oil/gunk. Stuff like that.

Hope to hear back on this.
