Have you retorqued your intke manifold?

 

[331strokerstang]

yes actually installed a new one still no help

valve seals on those POS pro comps? If its the trickflow valve-spring kit I have heard of them doing this right from the get go.

Was thinking valve stem seals as well.

Also PCV isn't a bad thing. It actually can improve performance a bit, as a vacuum in the crankcase means less air for wind resistance, and can help rings seal better as well. Just an FYI.

run it... read my post "seperator, baffle or both...

After i went thru a lot of anxiety learning how to do a leakdown. And, I will never buy a cheap tool again! LOL But thanks to stykthyn I learned something new and useful. I just thank god all is fine.

Now, I am going to run it in hard! But, i would check everything you can so you are sure...

sorry it took so long ive been out of town, but i know the pro comps a pos heads but i got them on trade and anything is better than e7s but im saving for a set of afr 205 or rhs 200 idk yet, and no its not trick flow spring kit idk what stem seals he put in, but i do know it has comp dual springs matched to the cam plus locks and retainers that go with it, i will have to check out your post man thanks for the help guys.

 

[stykthyn]

Not sure how I helped unless you are being sarcastic. I do know that the same baffle that was on the explorer was offered as a warranty fix for the frpp cobra lower after it was farmed overseas. To the op I would double check to see if the screen isn't clogged in your PCV valve. Other than that this smacks of valve stem seals.

 

[stykthyn]

Whoops just reread you have no pcv. I would set one up and see if it helps.

 

[331strokerstang]

no i wasnt being sacastic just thanks for all the ideas to everyone, and i did hook up a pcv yesterday, didnt make a difference at all. im almost leaning toward valve guides prematurly wearing seals bc ive heard those heADs have guide problems and they were used when i gotthem
