Where can you pick up a oil cap seal? I didn't see them on fcp grotons website.. Can you just get them from Autozone or something?

And, do you need a new cap when you replace the seal?

P.S. The MAF is the thing with the big plug that goes into it right before the air box (the big black thing that says turbo on it).. I was having the same symptoms as you and the problem ended up being a dirty MAF. I had no codes for about a month then the Check Engine Light decided to come on.. CPC (or whatever that company is that makes the electronic parts cleaner) now has a special MAF cleaning specific spray you can pick up at any auto store.. It's only a buck more than the normal stuff..

It's pretty short, like half a second or less. Feels like 2, maybe 3 cylinders just fail to fire in a row before it picks back up again like nothing ever happened. Spooky. And a bit unnerving at 80 MPH 600 miles away from home in the middle of the night, if you know what I mean. That being said, the faster the engine is revving the shorter the stumble is (just a blip loss of power at speed, vs. a full-blown stumble at idle). Make sense?

Thought so. My T5 does the same exact thing. From what I understand, there is an update to the ECU that gets rid of this otherwise harmless problem. I forget the specifics, but I need to go get it done because it really is annoying.

Wow. I'll have to ping the $tealer and ask about that one; Carfax (and the dealer!) said there were no open service bulletins on the car when we bought it. Thanks for the tip!

Give me your vin and I will run it through VRC2 (dealer service portal) and can tell you if R81 has been performed on your car or not. I leave seattle for the weekend at one though, so if you get the numbers to me after that I won't be able to look it up till sunday!

Why is this thread labeled NWS?

HORRIBLE advice. Positive pressure does not 'blow' seals, it just forces oil past them. Replace the oil filler cap gasket first, even if you did 'blow' <_< it up, $2 for a new seal is better than oil all over your shit.

I dont think it was horrible advice at all. If you leave a clogged PCV your cam seals and then RMS will start to leak. Then once they start to leak, even if you replace the PCV after that they will continue to leak. Maybe "blowing" the seals wasnt the right wording, but he is definitely correct in his prediction.

And I've got big plans to steam clean (or equivalent) the whole shebang once I'm done.

Head down to the coin op car wash with a can of foaming engine cleaner BEFORE

you start on the job. Much nicer to work in a clean engine bay...

They will not continue to leak/seap. We had a 99 XC reading posative 6 come in, get cleaned, and then return after a steam clean and two weeks. nothing. You ever seen +6? Our gauge doesnt go higher than that.

Hmm. Thats news to me. Good to know that though.

I have a RMS leak right now... I am about to do my PCV... will doing my PCV help slow or stop the RMS leak?

mine is not a big leak?

Thanks!

if it's not bad, there is a chance that it could stop leaking. just clean everything up nicely when you clean/change the PCV to see how fast it's leaking afterwards

edit: though not to get your hopes up, it will most likely keep leaking ;)

No, positive pressure does "blow" seals. The front exhaust cam seal is not uncommon. It's a slip in one behind the cam pos sensor. Ask me how I know. Personally, I believe that a lot of the oil cap gasket posts on here are just bandaid solutions to PCV problems. Gaskets do get dry and thin, don't get me wrong. I had that, too

Do you have any codes? That stumble sounds like a problem with your MAF... try some MAF cleaner on it and see if that helps. Clean the throttle body as well, both those are the most common problems for your problem.

I am going to get a car wash where they clean the under-carriage ... then do my PCV... and then see how the oil does

so doing the PCV will slow or stop the RMS leak?

ONLY if the PCV system is indeed clogged/restricted, AND the piston rings are sealing.

there is a whole hella've alot of "do the PCV " hype on VS as of late. It ain't a cure-all <_<
