what is the crankcase ventilation supposed to look like for sr20det?

My car is getting a ton of oil in the intake manifold, and after passing a compression test, im considering the possibility theres a problem with my crankcase vent system

the drivers side hose that T's at the valve cover seem to run to something behind the engine, and in the front where it is supposed to go into the turbo inlet, it seems to just have a filter on the end of it. I know it is supposed to go into the turbo inlet to create a vacuum on it to vent the crank case properly, but I am not sure if this could cause my problem

Theres your problem. Run it into a catch catch or turbo inlet and also take your hot side off and see if there is oil in the ic piping

Also, take your PCV valve off & clean it- Drop in in a container of gasoline for 10-15min... It will rattle freely when it's clean... Make sure all the gas is dried out before putting it back

Although it may be a good idea for a newish one that seems to be gunking up, most likely it's never been replaced and it's just plain old worn out. Personally, I wouldn't waste my time, but I'm not typically on a budget like others either. They cost like $20 and are matienence items, so they should be checked periodically. If you can blow through it either way, it needs to be replaced.

Adding a catch can routed back to a vacuum source is a good idea. Obviously the intake pipe between the Maf and turbo see's vacuum all the time and should be a sufficient spot for you.
