94 850 Turbo PCV Question

Post by zero324 »

I recently was replacing all my vacuum lines and decided to replace my intake hose since the PTC kept popping out and wouldn't stay in no matter what. While doing that I found that the hose that goes from the intake to the PCV box was broken in multiple places. I also currently have a small RMS leak.

I was wondering if I should just replace that hose or the the entire PCV system?

I'd vote for all the hoses in the system since you'll have to remove the intake manifold anyway.

If you're gonna do something, do it *right*! ;)

94s have two different kits depending on the engine serial number. That can (usually) be found on the sticker on your timing belt cover.

That's what I kinda figured. Oh well since i'm doing it right I just ordered the proper kit based on my engine serial number, fuel injector o-rings, and a new gasket for the throttle body since i'm there I might as well clean it also.

Hopefully my parts come in on Friday so I can spend the weekend doing it and take my time. Maybe this time i'll get my kids to help since they are older now and have always enjoined watching their mom work on the car.
