Chasing an oil leak

Any of you guys have oil leaking from the glow plug connector o-rings and if so, is a measured amount of weeping allowable?

I don't have an abundance of oil, but enough to run down the block but not form drips. I went with OEM everything when I chaged them out years ago, but am disappointed the o-rings are already leaking (if indeed they are).

I pressure washed the area and will confirm once I drive it a bit.

Thanks
Joe

Sorry.....had to stop and restart the thread a few times.

The orings that seal the glow plug post going into the valve cover.

I don't have a great answer for you here. When I put them in I was thinking of sealing them with RTV, but then went to grease when the thoughts of taking them back out again surfaced.

I might be possible to go with a slightly larger diameter o-ring, same ID, to get more of a seal, but I didn't try that.

Thanks Jack.

I will confirm the leak first, but was curious about the allowed/expected seepage with a component like this. I am pretty sure it is not my valve covers, but again until I confirm I cannot be certain.

I will get back with my findings.

Thank you
Joe

I think it's a weak design point on this engine. Too often we see leaks from these and sometimes I've seen the o-rings had split.

Just about every other o-ring or cord gasket on this engine a added T-31 to the outer area of the cord/o-ring.

Confirmed from the GP harness o-rings. For the life of me I cannot recall if I bough OEM or not when I yanked the motor out a few years ago, and something tells me I bought Dorman off of Amazon. Well the hell with it, I am going to replace the harnesess with OEM I bought from Clay over at Riff Raff. I have to install the BD up pipe set I bought last year to get rid of the leak and now is the perfect time to do it all while it is still cool and the f'ing mosquites are still in hell

where they belong.
