The shop that did the work said it was leaking from the lifter gasket?? I have searched the Internet to no avail. What could they mean? Anyone know? It looks to me that the oil drips out of a hole in the red metal cover just behind the oil pan. It has a new oil pan gasket.
So whats a lifter gasket?

cover have a gasket that quite often is the source of oil leaks.
the oil will run to the back and down the engine and pool in the
flywheel cover. That's probably why you see oil dripping from
the hole in the bottom of the cover.

You can also cut one out yourself from a sheet of rubberized cork gasket material if you really want that olde-timey experience.
Seriously though, find a close by parts store that has someone with these traits behind the counter; bald or grey hair, knows that a 1990 honda civic, isn't a "vintage-ride", and mutters about "these darn computers".

Now that I look closely, I have the same drip (from the flywheel cover), and I can see, after a lot of wiping, it clearly comes from the pushrod cover, not the rear main where it looks like it might be coming from. At least it's an easier fix to start with, then see if I'm losing anything at the rear main. Thanks again,

If its a 235 then the felpro part number I last bought was PS 5130. | | | | | Joined: Mar 2008 Posts: 283 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 283 | You didnt say what engine it was. If its a 235 then the felpro part number I last bought was PS 5130. I just bought that same part for my 235 (same '50 to '63 for 235) at a local parts store. Looked at internet sites and decided to try local for a change - voila! They had it in stock.

Thanks man, it's been an epic journey. It's back in the truck now, I'll try to get some more pics soon. Sorry for the thread jack. Do some searches here on installing cork gaskets, there's a lot of experience on using good sealant and what to watch out for to get a reliable seal. Be especially careful on that lifter cover since the bottom edge is pretty much submerged in oil while it's running. | | |
