Thank You. That's what I have on Hand. Just wanted to verify that's what You use. If this thing still leaks after this I don't want to second guess myself that I used the wrong Sealer. Going back together Today. Let You know if its a successful repair.

  

I only use the Ultra Black RTV here in the shop.  I have no experience with the plain RTV for the side seals.  I'll add that when I do the dollop of RTV and the side seal insertion, the rear seal retainer is not bolted down yet.  It's sitting about 1/16" off the block mating surface as this allows the RTV to creep under the seal retainer when the side seals are pushed into place.  When the seal retainer is brought on down and tightened, this insures that the mating surface between the seal retainer and the block is also sealed.

Question for Ted in previous Post.

  

I am not planning on using the T-5 Synthetic. T-4 is what the Rotella-T was before they added the 4. Been using it for Years. never had a problem with it. **Question for Ted**- On Teds Instruction Sheet there is a Tube of Ultra Black RTV Gasket Maker pictured. Is that what Ted uses in the side of the Seal Retainer just before the Seals are inserted? It appears to be clear in the next 2 Pictures. Will the Black do the Job?

  

Good luck this time around. Seeing your other post do you know if the seal material is compatible with Synthetic oil?

I did get the Upper Half replaced Today. Dropping the Crank by backing off the main Caps makes it easy. Just used some White Grease and compressed the Lip as I pushed it in a little at a Time. Still nothing wrong with One I took out so we will see if this makes any difference. Going to put it back together Friday. Repainted the Oil Pan while I had it off. Mine is more than One Spot the size of a Quarter. 

  

I never did stop the leak on my seal. See my previous posts on this subject. I have heard that the Y's mark there spot! I guess that is so, I'll just live with the leak as long as it doesn't become major. I have yet to get the car on the road. All the leakage has been on a test stand. Soon I will see how bad this may be.

I did everything correctly I think, first time using the Best gasket black seal and have a minor leak about the size of a quarter over night. I just live with it, not bad enough to me to redo it.

I did Jim. Followed Ted's Instruction Sheet.

  

Did you offset the seal so the parting lines aren't the same as the parting line between retainer and block?
