Default Oil leak, Missing PCV Breather and now Oil Leak again ...

Hi everyone,

Hope someone will be able to help me with this one. The primary problem is a huge oil leak which started during the process of fking up with my car,

Here is what happened,

One night I found couple cracked vac lines. Got them replaced. While doing it, found a little oil dipping out of the valve cover gasket.

Next week I have replaced Valve Cover gaskets. It was easy one, except for the fact that one of the engine pines gone. Oil dipstick was fine.

After the job the car was driving fine, no leaks or anything. But something still wasn't right ... sometimes it was driving just excellent, sometime like crap ...

A week after I've noticed oil spots on the driveway. I've decided to look further. My primary concern was all stuff under the intake manifold. When i removed the air hose from TB to intercooler, i found that there is a lot of oil in it, it t.b. e.t.c. After manifold was out, I've finally reached the thing ... The PCV breather hose was missing. Like totally missing. Oil were everywhere. I have replaced the hose, it's gasket, PCV valve, T fitting and cleaned metal tube which goes around the engine. I was pretty much happy at this point.

After this car was driving way much better (but boost gauge had been shaking like crazy anyway) and strange (LOL) smell has gone as well ... not for long though

Next week I went to my friends house. While there I've noticed a HUGE leak. It was HUGE. One could easily raise couple fishy there.
With bad feelings, I went back home.
The oil was originating from the driver's side, somewhere under the manifold, pretty much near the breather hose. I though that the breather hose has failed again but I had to sort it out as it was fine. I have decided to check the suction pump and here is the point where the miracle has taken place. I couldn't get air through this thing in any direction, it was completely clogged and the oil was dipping out of it. I have replaced it and also replaced Regulator Valve with DIY catch can (Husky filter from home depot) plus couple check valves. After putting everything back together i took a test drive and the car was driving remarkably better, everything was better, IDLE, acceleration e.t.c. EXCEPT for oil leak which still exists ...

Whatever is leaking it was caused by crappy PCV ... last thing I did, i changed the oil and filter and the oil in engine was black ... like the oil in PCV..., It really seems like the oil is coming from oil pan gaskets but it is not ... however entire area near pcv and everything below covered with oil. Today i've also noticed that valve cover gaskets leaking again and leaking badly. Is it possible that they are leaking from the back side of the engine harder?

I am going to take out manifold this sunday and check every single thing there, clean everything and replace the valve cover gaskets again. Any idea what I should look at? What lines, gaskets keeping in mind all PCV stuff i described above?

Thankyoumuch
