Overhaul gasket kit... first thing on the list will do it.

The dowel pins get a .20 cent rubber o ring btwn each housing. That's it... Too bad it requires tearing the whole engine down to replace.

Although there is a trick others have talked about working. Search dowel pin gasket repair or something of the sort. It involves drilling exactly where the o-ring would be and filling with some sort of gasket maker or something that will re-lifen the o-ring from being dryed out. I'm not sure on the specifics.

Me personally I'd rather tear the motor down to see what's going on inside then a band-aid.

I have done the drilling method. Works fine.

The drilling is easy to do. Since hole is as big as nidle, it’s not noticeable at all once the procedure is done.

Cost me 2$ to make a syringe to have high enough pressure, but no oil leaks, and good oil pressure since then.
Only major down point is 24h wait.
