SRT4 PCV Improvement

[BadFastGTC]

Those of you who own the SRT4 may or may not be aware of the fact the factory PCV valve is more of a "positive crankcase pressurization" device. Many people put a checkvalve in the PCV line. I decided to try a different route. I took a stock SRT4 PCV and hacksawed off the top. I then removed the useless internals. I trial fit a TII PCV These do not leak boost. Tight, but not quite right. There are 4 raised lines that serve as a stationary for the stock check valve "seat". I took a little material off the TII PCV and it fit very well. I tried an o-ring to seal the two pieces and wasn't satisfied with that. I ended up using good old JB Weld to put the two together permanently. I haven't had a TII PCV valve fail yet. Hence, the permanent coupling of the two. Total time: 10 minutes.

Never heard that, good to know!

Nice work Steve. I just ordered a check valve for mine as it's that last boost leak I've got to seal, but I found the mfg for them and paid $9.99 by buying direct instead of the $38.xx that they go for on the srtforums.

That's problem on the SRT-4 and many other modern cars. The PCV valve sucking the unwanted stuff!!!!

Good idea, I missed this thread when it was first posted. I will have to put this on my to do list for my SRT-4 along with a catch can.

Without pressurizing the crap out of the crankcase, you may not need a catch can.

I ran an inline pvc that I dug up in the parts store in the line to the stock pvc on mine. Worked like a charm and did not see much oil through the intake track at all.

Food for thought. Maybe if I could get these TMs in my driveway done I'd have time to fool with the SRT-4.

Steve, I've noticed allnew brands of Dodge turbo PCV valves leak boost, even the OEM ones now. They used to have a rubber seal but I guess cost took over and they are just hard plastic.

Twin turbo Supra's will not leak one bit of boost, I've air checked it against OEM Dodge ones-which all leak, some worse than others. They are metal, $10 at the dealer, only use OEM.

seems like a good idea going to try it.

Thanks Simon

Simon, I ordered a couple of these at work. Nice valve! Thanks! FYI, THESE ARE STRAIGHT VALVES, NOT 90 DEGREE UNITS.

how did you go about installing it?

[ScottD]

I copied Steve's idea but to try something different I used the Supra pcv. It fit pretty snug in there but I sealed the top off with RTV. I hooked it up with a 90 deg hose off a TD w/ another short hose that had a slight bend to it (it was a shortened TD brake booster hose). I used a vacuum connector to mate the two hoses but cut the little pieces off it so I could squish the hoses together and make it look factory. Turned out pretty good.

Thanks for the pics Scott!

Hey Scott, your pcv valve is metal but using the part number provided by Turbovanman brings up a picture of a plastic looking valve. Is your the same part number or what was the one you got? I was just randomly browsing the web looking for ways to fix vacuum/boost leaks and came across this idea. And would this help with oil in the intake or would a catch can and check valve as well help to keep it bone dry? I'm still learning the ins and outs of SRT's.

[ScottD]

The valve I got is a Purolator valve from Pep Boys. Can't remember the PN but you should be able to look it up in their book.

Regarding catch can/oil in the intake, below is what Pat said in an earlier post:
