Cheapskate Plenum Gasket fix?
I just replaced the plenum gasket on my 93 5.2 Magnum.
It was using oil mysteriously, and pinging. I removed the throttle body and looked inside. Oil pooled inside.
Once I removed the intake, the old original gasket was rock hard, and wobbled in and out of position, like a snake. Lots of leaky spots.
Someone mentioned to me, to check that the bolts weren't too long. So I did, and guess what?
With the plenum cover and gasket removed, they all bottomed out before contacting the surface. They are a dog point bolt (meaning they have about a 1/4" non threaded tip. So I ground them all off about 1/8".
New Fel Pro blue gasket. It is wider than original, and has sealing strips moulded in place. Nice part.
Sure runs nice now.
Hopefully problem solved.
