oil leak in 2.4

[Fritz Peyerl]

Had a very spirited drive a while ago and the next day, I had a puddle under my car.
I thought the from main seal was leaking, as all the traces of oil came from that area.
Winter set in, where I live and the engine came out. The Seals arrived from Pelican and I wanted to start the job,
I cleaned the engine and left it sitting for a day, next day I had a small puddle on the floor, I checked and found no traces from the crank shaft seal. But I found a dark spot in the case and a trace of oil coming out of it and running down the casing.

Question:
would JB weld do the job, or should I split the case, drill and tap the hole and insert a plug. Splitting the case is not the reply I hope to hear.

I have another case and could start rebuilding the spare case and transfer all components.

What are the expert recommend??

I'm no expert but if that isn't a pressurized spot I would think if you and get that area clean and oil-free then JB Weld would hold up fine. I am just perplexed how the hole got there.

JB Weld it. Mine was covered with something like JB Weld from the factory. I used the JB to cover all the plugs like that on the engine during the rebuild.

I would not use JB Weld. I have used Dow 730 aircraft sealant ($99.00 a tube) that will actually seal the oil leak.

Here is the description of it: "A one part RTV paste which cures at room temp. to a tough rubbery white solid. Used for bonding, sealing and caulking where resistance to fuels, oils and solvents is required. Excellent on fuel line pipe threads, repairing fuel lines and tanks, bonding components exposed to fuels, oils & solvents. temp. range -85F to 400F. Stores refrigerated for years. "
