I ordered the non OEM kit for replacing the oil separator and vacuum pcv system on Amazon. It It was around 30 bucks, and I figured, hey, why not? Some of the people on the reviews mentioned o-rings that didn't fit, and that there was an inability to push them into the tube openings.

In the process of taking the original pcv tubing apart, I realized that the quick connect convenience that they offered suffered substantially over the last 18 years.

Trying to push the new fittings into the old tubes was absolutely impossible. Silicone lubricant, heat, muscle. NOTHING was going to make those tubes with the o-rings go into those old tubes.

Since these ARE just vacuum tubes, I decided to make a move, since the so-called customer service for the Amazon vendor TOTALLY dropped the ball on any repair assistance correspondence.

I took out the o-rings completely, and applied RTV sealant in the places where the o-ring would have made contact. Pressed the tubes in without much resistance, and... voila! Sealed, connected tubes, still clicked in with the fastener!

I put everything back together, and I'm rolling down the road. Smooth as silk.

So, someone might say that it's going to be a mess to get these apart if I need to service them in the future. My response is, I've NEVER been able to successfully disconnect or reconnect these tubes before, and I can't see any occasion that I would need to. And, if I DID, I'd tear off the RTV and apply another bead for reconnecting. RTV is cheap.

Any objections to this method? I used an RTV that was safe for sensors,and I feel confident that it's not obstructing anything. And it's working perfectly

UPDATE: AND, after driving it for about 90 miles, the check engine light turned itself off!

Epic fail! Had to go in and remove all of the RTV, and use grease to reattempt insertion. Voila! It worked!

The RTV wasn't the really good stuff, or the Right Stuff, either...

I was getting SES light, CEL...

I went back and cleaned off the RTV from all of the snorkels, and reinstalled.

I'll report back with more findings...

Add the last 7 of your VIN (2 letters and 5 numbers) to the thread, and folks on here can help you zero in on the correct part(s) for your specific chassis.
