Oil Leaking from Distributor and Starter on '89 YJ
I just bought a used '89 YJ. The engine was replaced and is supposedly
not that old. I have beed dripping some oil after I park and have been investigating the leak. I went through the usual recommenations of checking valve cover gaskets, back of the head etc. I have definitely found one leak - at the base of the distributor. From what I have researched, I need to change my oil pump. What's puzzling me though is that I find oil weeping out of a hole in the bottom of my starter - and also possibly out from under where the started mates with the bell housing dust cover (or whatever that flat metal plate that covers the bell housing is called). Could this be a blown rear main seal and oil is getting into the bell housing and then out through the starter? There is no oil coming out IN FRONT of the bell housing up where the u shaped end of the oil pan is. Bill Smith |

IF so then all you need is a new gasket, or someone horked on the holddown bolt too tight. Check the inside of the distributor for oil. If you find it there then you need a new distributor or will have to rebuild the bushings. It's easier and lasts longer with a new or rebuilt one. http://revbeergoggles.com/distributor/ > What's puzzling me though is that I find oil weeping out of a hole in > the bottom of my starter - and also possibly out from under where the > started mates with the bell housing dust cover (or whatever that flat > metal plate that covers the bell housing is called).

Give it a good wipe then come back a day later and check. The I6 is notorious for leaking at the back of the valve cover and doing a damn good impression of a rear main leak. -- -- DougW -- 93 ZJ 4.0 http://members.cox.net/wilsond HESCO Supercharger - 300W IASCA Stereo - Edelbrock IAS Shocks Gibson Exhaust - rear DCpower - custom gauge install - Stillen Rotors Banks Header - and BEER, in the fridge! |

Re: Oil Leaking from Distributor and Starter on '89 YJ
Doung thanx. I read all about the back of the valve cover deal and went
through all that already. And from what I understand, that would have the oil showing up near the rear of the oil pan which it's not. And I wiped everything down and then let the engine run without driving so I didn't confuse things with oil being blown back. It seems to seep straight out of the little hole in the bottom of the started and under the lower mounting bolt. As far as the distributor. I thought that there shouldn't be oil coming up that shaft at all unless the seals on the oil pump were shot.

I've got an oil drip that travels down the valve cover and runs down the side of the engine. Fix it every now and then with some cleaner and a skim coat of rtv. One of these days I'll actually re-do the gasket. > And I wiped everything down and then let the engine run without > driving so I didn't confuse things with oil being blown back.

One of those bolts might be like my old chevy and actually go into the block enough to weep oil. Plus you would be able to see the flywheel and check if it has oil buildup. > As far as the distributor.

Not that it couldn't be the oil pump seals, but usually bad pump seals = low oil pressure. There is another seal that is part of the distributor just between the oil pump and the camshaft pump gear. -- DougW |

Re: Oil Leaking from Distributor and Starter on '89 YJ
I do the same thing . The tappit cover leaks. I just dab it with rtv.
Once in a while. It leaves oil marks every where i go. But i tell every one that bitches she's marking her territory. Some day I'll fix it right. Later Mike |
