use a socket and socket wrench to "tighten/screw" down the housing. easier and more precise than hand or screwdriver, trust.

Wait... we're talking about a L36, right? Pretty sure that is the right part. The Dorman part is slightly different from stock, IIRC, so its slightly less likely to break.

I'll double check mine tomorrow... I have a spare Dorman package in the garage.

If we're talking L67, then the housing is completely different.

That part, the clips won't fit the MAP sensor I dont think?
I ordered an AC Delco one from rockauto I'm told matches my housing?

I've attached a photo of the Dorman PCV housing with my stock MAP sensor. As you'll see, it fits the MAP fine (though mine is a bit crooked there), but in a slightly different way than stock. The Dorman housing, IMHO, is less likely to break as the plastic becomes brittle. The stock housing "fingers" are so easy to break, that I don't think I've ever gotten one apart without breaking at least one finger.

That'* how the ACDelco looks too. Glad it'* the right part. So basically, it won't look straight but it'll be fine?

I recall it being straight when I put it on 2 years ago. I guess the gasket collapsed a bit... or the engine cover bumped it.

Its not causing a vacuum leak, so I'm not screwing with it for now.

The engine in the car was running very good when the tranny finally died. Only thing I could wish for is MORE POWA! Well, actually, a bit more oil pressure would have been nice, as it used to be ~60-70psi, but now lives more like ~30-40. Its nowhere near as low as my worn out 307 was... which would 'pulse' the idiot light at idle... apparently that is like 4-5 psi. Whoops!

I ended up breaking the MAP sensor putting it into the new housing, so I gotta buy another new MAP sensor. :/ It'* a hard as hell time to put it together!

Also, making sure...did you have a spring with your pcv?

Yeah, I read that in the other thread. Your MAP sensor must have been really brittle... I've been real happy with the new setup, compared to the original... easy to put together, easy to take apart.

Yes. I distinctly remember because it was crazy hard to compress the PCV, spring and housing top enough to get the housing threaded on without breaking the clips. If I did it again, I would think of finding a way to weaken the spring slightly... but its a pretty robust spring.

I can see why some guys would toss the spring in frustration, but I don't think thats a great idea.
