Positive Crankcase Ventilation thru PolyVinylChloride?

[daeron]

Yes, this is a question about PVC in the PCV.

 

Okay, so my engine cries oil. Some of it is power steering fluid (i think,) some is definitely weeping enthusiastically out of the drainplug (need new seal,) and generally speaking, 2/3 of my engine is covered in sandy greasy gunk.

 

Obviously I need to clean it (even though it was sparkling in March after the HG job) but before I get into that, I want to fix KNOWN contamination issues like the drainplug, my popup oil dipstick, maybe the oil filler tube gasket, and DEFINITELY replace all the intake manifold vacuum lines (IAC and PVC etc) All of those lines have vapor "weep" evident at the T's, and the car has never had the "recall kit" installed bypassing the smaller vent on the reverse passenger side of the TB boot and connecting the two fat lines together.

 

I have looked for the two little tees that would be needed in every soob I have seen in the junkyard, and today I set out to try to source two tees from ANY vehicle, as long as they would work... and got SKUNKED. SO, I am wondering if I could simply get a couple PVC tees (maybe the type used for sprinkler systems?) and use those, and some new hose from the parts store, to make my OWN "recall kit." My PCV valve is good; the lines are brittle and I doubt their capacities to form a good seal anymore.

 

Would this be a bad idea??

 

Anyhow, from that point I degrease the engine, watch the steering pump, and either repair the leak or replace the pump with a dry looking JY unit, and see how much oil is still winding up everywhere in the engine bay... but thats beside the point.

 

Thanks in advance for any comments.

PVC "T's" will be fine.

 

You want to pay attention to the quality of hose you use in the PCV system, as engine vacuum (under high vacuum conditions, just when you need a working PCV system) can cause "lesser" hose to collapse (or be sucked shut), effectively making all your work for nothing.

Most auto parts stores sell hose designed specifically for PCV applications.
