Hi All!

I noticed another slight leak today :( .  See attached pic.

 :?: Can this leak be fixed by simply unbolting the allens and replacing the gasket?

 :?: Anyone ever do this procedure?

 :) Thanks!

Bob,

I have many leaks also, and will watch this thread.  Is this at the front of the engine, passenger side, under the headers?

The cover plates on the right side of the engine block are coolant jacket covers. The only oil passages in the block are on the left side of the motor. Are you sure that it is an oil leak, not a coolant leak?

Oil leaks at the front of the engine will show up on the right side where your picture shows oil residue.  A good candidate to check (besides all the usual culprits) are the two socket head bolts inside the chain gallery.

Thanks Al & Vince,

It probably is oil from the front and even a small bit of coolant, so when it hits the garage floor, it looks like oil.

I will change the heading on the post to simply "Engine Leaks!"

 :?: My question still is...  to change the gaskets on these small plates on the right side, is it as simple as:
1.  drain coolant
2. unscrew allens
3. replace gaskets
4. button it back up!

 :?:  :?: Has anyone done this one?

 :) On a Winters mission to get my 113 engine leak free & a dry garage floor...

When rebuilding my engine, I noticed these water jacket "plugs" appear to be sealed with a hard gasket former, long with the OEM paper gasket. So I used Permatex Form A Gasket along with the new paper gasket during reassembly. No leaks so far and has been close to two years

Bob - The procedure is as you describe.  Careful with the allens, of course, if they have not been moved in 30+ years.

Has anyone ever tried Bar's Leaks Rear Main Seal Repair to stop leaks?
