o ring sealant

[bud36light]

Need to know the best type of sealant to use on the distibutor o ring. What has worked the best and for the longest time? Give me months- miles etc. In this case price should not matter. And should I throw a small block dist gasket in there with the sealant and o ring too? Lets hear some opinions...

I used....

I used Ultra Copper silicone.
700° Temp resistant
High Oil Resistance (A must considering what your sealing in)
Was only 8 bucks.

I'm in your shoes as well, I just did the job over the weekend, no leaks yet. (Before it was just gushing out)

I decided not to use JB because one day I may have the nerve to remove that back head and do the job properly.

Just make sure you get up and under the plug cap. I really kinda overdid it but I did not want to have to take that damn lower intake out again.
I had to do it twice in one day as it was.


Good Luck, and make sure you change your upper and lower gaskets as well.

I had the heads off the 91 at about 132k miles about 2 years ago. I put a new o ring (was not automotive grade though), tons of black silicone, and a small block dist. gasket. 155k miles and 2 years later, no leak.

I wouldn't seal it at all. If it is loose, get a .010" oversize ring. You can use the small block gasket, but on a small block, it isn't there to stop a leak. It is there to stop the distributor from freezing up, (Electrolosis), so you can turn it. It has an o-ring too, to stop an oil leak. Look at a small block distributor, it has weep valleys on the bottom of the boss,(where the gasket is) to let you know the o-ring has failed.

I did not mean to say I used sillycone on the o ring itself, because I did not. I used silicone on the bottom side of the "head" on the plug, as well as on the gasket because I thought (not having pulled a SBC dist. before) the gasket was to keep the oil from coming out.

Dat's why I said it. I have never done this on a V-6 DOHC before,(getting ready to) but physics never change. There is never a wrong way as long as it works. Since this is never turned to adjust timing, it is probably a very good fix.

On the wife's 92 Lumina LQ-1 I used an old Chevy smallblock distributor gasket and some Hi-Temp CRC Red Silicone. Loosened the fucker up, notched the top of the plug about 1/4 inch so I could get it up enough. Then snaked the sliced gasket in there, totally impregnated everything with sealer, twisted the plug so it was sure to go everywhere. Tightened the fucker back up and let it sit overnight and cure. Did that about 1.5 years ago, still dry as a bone. Of course, then the damn oil cooler started leaking, so I put a starter in that last week and pulled the cooler out, used same silicone sealer, same cure time. Absolutely no leaks-WAHOO!

My 93 Olds has 119K on it now and still doesn't leak at all, much to my amazement. Of course, it doesn't have an oil cooler on it either for some reason.

Hope this helps, good luck.

PS: Thanks to Ben and whoever else helped with the pics and procedure for axle removal method to do the alternator, it was not that bad at all.

Has anyone ever tried Permatex Aviation Form-a-Gasket? That's good shit. We used it on all sorts of shit at Optimax.

Thanks for the info. Wanted to see if there were any nay sayers as far as using sealant.

There is never a wrong way as long as it works. Since this is never turned to adjust timing, it is probably a very good fix.

This is good info. Again thanks, Kevin

Do I have this infamous problem also??????

I have had a massive oil leak develop in the last few weeks, too much to live with and am in the process of replacing the oil pan gasket. Like everything in repairing this car, pulling off the oilpan has turned into a massive freaking job and to top it off I don't think this is the problem.

As I now have the tranny & engine mounts undone, the motor raised enough to get enough clearance from the engine cradle to drop the pan. I decided to change the back plugs while I could get at them. This has lead me to think maybe the pan gasket isn't the problem. The back # 3 & 5 plugs are soaked in oil. I don't think a pan leak would cause oil to get up this far? The entire bottom end, including the front of the block is coated in oil. Can this much of an oil leak come from the damn distributer hole??

I guess my question is, how does someone determine if the distributor hole is a source of the leak for sure?

how would you go about fixing it properly? mine does the same thing and if i'm gonna invest the time to fix it then i'm gonna do it right.
