This is actually a big issue on every dsm/Evo that runs alot of boost. There is only a point of cylinder pressure you can get to untill it passes by the rings. When you guys start to run alot of boost or make big power you will run into the same issue. Also when building an engine for big boost the ring gap is bigger than normal so when boost initially comes on (and the ring gap is not sealed from the heat yet) The blowby will cause this to happen. Better safe than sorry -Em ---

good job, I like itā€¦ Iā€™ve never had a problem, but with 3 1" outlets(1 off block and 2" off valvecover) I can agree that there is a LOT of pressure in the block at a bunch of HP levelsā€¦ it still flows like crazy. And yes, ring gap is higher at higher HP levels. Necessary Evil. ---

Also ring gap on a supercharged or turbocharged engine is a little bit larger than normal. Not anywhere close to a ring gap for nitrous engines. The ring gap never completely seals. If the gaps touch and bind you have problems. Blowby is NOT from the minute gaps in the rings, it is from the rings that are worn out and/or cylinder that are glazed and worn. A fresh nitrous engine with .030" top ring gap will still leakdown at or under 1%. Plugging off the dipstick will just cause the pressure to go somewhere else (oil pan gasket, rear main seal, front main, valve cover) More of a bandaid & you would be better off lowering the boost or rebuilding the engine ASAP ---

> [@newman](#): > > isnā€™t this what a PCV is for? Is there really THAT much blowby? I had 75% leakdown in cylinder 3 in my STi and I never had the dipstick pop out. PCV valve is closed under boost so it cant relieve pressure out of the crank case. On stock mitsuā€™s this is an issue. Yes there is an extra port on the valve cover but at high rpmā€™s its just not enough. The proper way to fix the issue is to create vacuum on the crank case. This will help to insure your rings pull tight against the walls. There is no such thing as an engine that seals with absolutly no blowby The difference is determined by cylinder pressure and ring gap. With our 2.0 liter cars making as much or more power then engines 3-4 times bigger than them there is alot of it. -Em ---

And as far as extra insurance goesā€¦ What comes first? The dipstick popping out or the leakdown test? Most people need a reason to do a leak down test and with a toasted car that started on fire they wont be able to.
