leaking oil from valve covers?

[BerniniCaCO3]

Just switched to a semi-synthetic, hoping to be better for the engine.
Though it might already have been leaking.

...just tighten up some bolts as a solution? Or is there more to it than that?


thanks!

new gasket time

yep, replace the gaskets. or tighten them if you want it to really piss oil. Crunch those hard cork gaskets down and the oil just pours out.

while you are at it replace all the vacuum lines under the upper intake and replace the pcv valve and screen.

do you mind attaching the link for the thread, HatNinja?
OH-- and in the "everything I learned about..." thread you started, you included two other links to threads that were incomplete (the ... in the middle of the link, continued with the url: so the link didn't work).
I'm interested in the tv bushing thread you'd highlighted, could you post the full, working link?

thanks!

wow i just checked those 2 out and you are right try doing a search on tv grommet, and a.i.r. removal you should be able to find them.

cool! Got some help, and did it all yesterday! I was a bit intimidated to touch anything on the motor, just yet, but it worked out fine! No more oil leak, and man, was the poor pcv valve in need of changing (and the filter).

Only issue was when I overtightened and snapped off one of the bolts going through the valve cover, but we got it out.. Scary.

My friend also showed me where that throttle valve bushing is located, that everyone's been talking about. Still a mechanics newbie: just had no clue what/where it was. Does the ford dealership generally carry the brass one? Is there any sensitive adjusting to be done, or can I just swap it out?

Oh btw-- after replacing the pcv valve, filter (both of which may have been original for all I know...), and the gaskets: the motor seems to give me more power, but also run a little louder. Perfectly normal? We're not talking worrisomely loud here, just, when one's attuned to one's car: a decibel or so louder than it ran before I changed the pcv valve and gaskets.

[gadget73]

probably a good thing. The pcv system does move air through the motor, so that might be what you're hearing. You'll also get a slightly better piston ring seal with the crankcase under zero or slightly negative pressure.


Ford dealership will possibly tell you the brass one doest exist, is obsolete, or the part number is invalid. I dont know why but they don't seem to have any clue what people are on about when it gets asked for. Its just a simple direct swap procedure when you get one though. No adjustments required as long as you don't meddle with that adjuster block.

look up ford aod overhaul on youtube, there's a few videos of guys adjusting and showing the correct procedure for setting TV pressure
