So, there's the issue of the PCV valve on 99's allowing oil to pass into the upper intake and can lead to some detonation.

I've seen az2kvert's site showing how he added a Fuel filter in line between the valve cover and the intake, on the pcv tube.

Is this something I should consider doing, or maybe see about getting new valve covers

actually when i took myn off it had some oil in it. The best inside pic i got is this. Is this what the inside of your intake looked like somewhat?

thats the best i shot i got of the inside of my single port runners.

Mine was oiler, blacker, but in general it looked pretty bad also. Monkey commented that it was normal, so I didn't give it a second thought until I ran across this

When I put on my stage 3 upper the stock one I took off was relatively clean. Smokedya95stang yours was much more grungy than mine was but then again your car is a 95 so eventually mine could have looked like that

didnt exactly read all of this, but it may shed some light on your situation.

well i didnt have a problem that i know of, car had 23k on it, but i pluged mine off and put breathers on the valve covers to prevent the issue, how offten do you need to replace or clean those filters?

 

[Ken]

I don't know. From the pictures it looks like its clear so I would guess when it gets black, or you get a CEL that relates to the PCV.. is there even a CEL for that?

Parts dude "Highly recommended" that I get it installed by the service department.

I told him it's just a valve cover

I decided to have FORD do the install bacasue they are gong to clean the crap outta my intake manifold too:

I am so frustrated I am not going to explain it here but the whole ordeal made me start this thread:

Call these folks if it applies to you. they are nice and hopefully this will encourage the engineers to pull their heads out of the V8's engine bay and take a look at the V6's problem(s).

*edit* Aye kunt speel four sheet

If ford does the install I heard that ****** the timing a bit? Any truth to that. I'm running into the same problem and need to deal with it soon

Yes it does. The oil vapor "dampens" combustion which hurts power as well.
