Well its still leaking! I removed the nipple and heater hose pipe plugged it to eliminate a possibility of a leak and its completely dry. It starts leaking almost immediately, a drip every 5 seconds right off the bottom of the pan where the rear main is. I think its definitely a freeze plug, its probably running down the rear of the block hitting the bottom ridge and running onto the pan. Guess my options are the barsleak or pulling the transmission to replace the plug.

Anyone think I should drain the oil and check that? I wouldnt think coolant would be leaking past the pan seal with no oil present at all right? I dont have a dipstick tube in this car as I was going to use the Canton dipstick but the dougs headers made that impossible

Just look in the valve cover filler with a flashlight.
Any coolant in oil turns it into a chocolate looking milk shake .

Yeah its the freeze plugs. I was able to get an inspection mirror behind the torque converter and could clearly see antifreeze running from a spot where the edge of the plug meets the block. Crap.

The problem is that it shreds and contaminates the system. Therefore, worse on oiling systems than on coolant systems. And why it works just fine for natural gas installations--which tend to last the life of the water heater or furnace; potentially decades before a person needs to dick with them again. And those applications also tend to be out in the open making for easier clean-up. Which is why a chemical solution (anaerobic paste sealer) is much preferable to Teflon (PTFE) "tape" on automotive applications, since there's almost no product remaining in the system after disassembly, except what's easily removed from the male fitting; and traces on the female side. All the excess squeezes-out during assembly. I've had all I can stand of picking thread tape out of castings or fittings with a tweezer 'n' compressed air. The anaerobic sealers are so infinitely superior in that regard--provided at least one of the fittings is "active"; iron/steel/brass. (Aluminum isn't "active".) Otherwise, applying the Permatex "activator" spray is enormously helpful. |

"Thanks for all the replies, super helpful all the way around. I did use tedlon tape originally but will be switching to a thread sealer tonight."
We are WAY past using teflon tape on anything. It's will work but MUST be wrapped correctly and it's a one time deal as it shreds into scores of thin pieces if you back the fitting up anywhere along the way. Get and use this instead, our local Rural King has it for about $15 for the large can: https://www.summitracing.com/parts/p...iABEgLOXvD_BwE I discovered this stuff way back in the 1980's and chit canned all the teflon tape and never looked back.......

The company I worked for spec'ed the anaerobic sealer. I forget which variety--may have been 565, or 567, or maybe something else in that same family of products. (I use 592 in my home-shop) But we had perpetual supply problems; the "head office" wouldn't send us enough of the "good stuff". So the local officials at our plant bought the giant-economy-size tubs of the stuff Cliff linked to. Within one week, the supervisors confiscated the big tubs and made sure we had the anaerobic sealer--the fluid leak rate went out-of-sight. As soon as the anaerobic sealer was back in general use, the leak rate magically went back to near-zero where it was before. Strangely, they did the exact same thing about a year later. The results were predictably identical. About a week after giving us the tubs of solvent-evaporating sealer, they confiscated 'em again, and gave us the anaerobic stuff like we should have had all along. I've been a believer ever since the first time they tried to replace the "good" "Teflon" anaerobic paste with the "cheap" brush-top tubs of "Teflon" sealer. Some time later, I put in a request to the Company to take home the solvent-evaporating brush-top tubs of Teflon sealer. My request was granted, they wanted nothing to do with the stuff any more. I painted embossed-steel-shim head gaskets with the stuff. Worked great. Last edited by Schurkey; 09-29-2022 at 04:32 PM. |

Teflon tape should not be used on a automobile. It is asking for problems, I have used the Permatex white teflon stuff for years, works. I have used Permatex # 2 on threads, works fine.
I use Permatex Aviation on the oil galley plugs in the engine because it does not dry/harden and it works great. Teflon tape is for plumbers. |

Let’s see if I got this right then.
Plumbers use Teflon tape in water systems, but yet it can’t be used in a cars cooling system connections . Please stop with these never never statements.

I would take the PIA route to fix this and drop the Trans.
God forbid there is a crack at the rear of the block you want to now about now, not when parts come flying out the block at 6500 rpm one day!

Im So tempted to try the bars leak. The machine shop that assembled the lower end suggested it too. I can see the spot its leaking from and the plugs look like they were installed properly, probably a small nick in the block or plug that the sealant he used didnt fill well. I did order mew plugs as well.

I imagine it wouldn't take you more than a day to remove the trans, replace the leaking plug, and get the car put back together though, right? I'd just take a Saturday and get 'er done.

Who did the machine work? They should be stepping up. I would pull tranny and fix it now, or else wonder every time you use it if the sealer will fail.

Mid Cape Machine. I did call him and he was vey apologetic. Im sure if I brought the engine to him he would fix it but I'm not pulling it. This is the first engine I have farmed out as I always build them myself but he offered and im limited on time these days with work.Im going to bite the bullet and pull the trans and replace it in car, plugs arrive today so I'm going to start after lunch.
