hi guys, I recently replaced my coil pick-up, but after I re-installed the distributor I was getting a bad oil leak. I didn't know there was a O-ring seal on the distributor shaft. Can anybody tell me exactly where the oil seal is supposed to go on the shaft? I'd really appreciate the help. Thank you.

theres a groove that the o ring goes into

the o-ring is felpro part number 70800

or 14-1020

 

kretos, thanks for the fast reply. could you tell me approx how far up the shaft the groove is that the O-ring goes into? just so I know exactly where to look. I already have the new O-ring, got it from GM....Thanks again

i believe its near the bottom, once you have the distributor out you'll see it clear as day

 

kretos, great, thank you very much and thanks for the fast reply again also :-)...have a good day/night

 

no problem, if you have anymore problems just post back here

 

GM part number is 10477565 for the distributor o-ring. About a buck each from gmpartsdirect.com.

 

The O-ring fits on the housing a little below the mounting flange. Heck, I have a distributor nearby, hang on for a pic.

Pic shows O-ring just below the flange.

P.S. I needed a new post in order to include the pic. Always thought I could edit a pic back in. . . Guess not.

 

(In before Karl) DOn't forget to also include teh $0.90 sbc distributor gasket to be put on before the distributor gets put back in.

 

I and others have included in past write ups on how to simply rebuild your distributor before you reinsert it.
That does also include my suggestion of adding a Small Block Chevy distributor gasket to the mix before inserting distb back in engine.
The gasket is only a buck.
Definetly helps in nearly a complete leak free are back there.
I use a film of black RTV sealant on both sides of SBC gasket, really helps makes sure of no leak.
Number one plug for these V6 is at passenger front cylinder.
With rotor pointing at 7:00 position on the distributor when ya remove the cap, you're pretty darn close to TDC.
Look at balancer you should be near zero in balancer pointer & timing mark.
Distb are not easy to remove due to aging. They like to be "stuck".
Keep pulling UP and distb will "eventualy release from the engine".
When done rebuilding distb, resinsert into engine.
To compliment this distb. rebuild, add new timing chain. Then your timing system is rebuilt, engine runs stronger, cooler & better gas milage. It's a win-win project. Cost runs ya into the $70 range, all the stuff (chain, distb. parts, gaskets).
