Any other ideas? Annabelle has a 292 that I have replaced the rear main seal in. It had a neoprene seal and I replaced it with a new one. I put Bar's Stop Leak into the crankcase. I don't drive her much anyways and the last couple of month's I haven't even had time to start her up till a couple of weeks ago. Now she's leaking more than ever, maybe 1/4 to 1/2 quart in 15 mins of idling.

Anyone have any other solutions to this problem?

 

Sounds like the rear main seal - again. It is easy to put those in poorly, from what I understand.

 

Buzz is probably right. Not many places can leak that bad. Where is the oil coming out? I guess it is possible that the pump could leak that much and you should be able to confirm that the oil pump is not leaking without much trouble.

How did the crank shaft look? How did you seal between the two halves? RTV?

 

sometimes the rear main seal cap is warped. this can cause issues with the crank seal or the wedges along the side.

I would recomend replacing this the next time you have it apart

 

Thanks for your guys' help.
I can't tell for certain where the oil is coming from. It doesn't look like it's near the heads. Seems like it's coming from behind the flywheel. Could be the rear main, again but I hope not. I've read where there are some threaded plugs this happens at.
The crank looked okay to me. Had the little hash marks where it meets the seal. The lower seal retainer seemed pretty square. I used my speed square to check it out. I put it back together with a copper based RTV. The toughest part of the job was the transmission. I'm not looking forward to fighting with it again.

 

These jobs alway go better the 2nd time.

 

That seems like large amount of oil for a new main seal, are you sure you didn't install it backwards? Hope it isn't the cam freeze plug.

 

Did you by chance install a PCV system on this? Or do you still have the road draft system? It may have too much crank case pressure if installed improperly or has a blocked road draft screen.

Sometimes people have eliminated the road draft because they drip only to increase crank case pressure causing other problems.

Probably not an answer to your problem, Just throwing it out there as a possibility.

 

Bigwin, That may just be it. I haven't installed a PCV and it did not have a draft tube when I bought the truck. There was this hole (pictured) that I had asked about in a different post awhile back and I don't think I got any definitive answer. I ended up blocking it with a bolt so it would quit spewing oil all over the top of the motor. Is this where the draft tube would go?
Thanks for every ones help.

Thats not for the draft tube, it is located on the side of the block. It will be a large hole with two smaller bolt holes. If it is blocked off it will have a plate over it similar to a fuel pump block off plate. If that is blocked off you need a PCV system..

 

That hole is where the body ground should connect to.

What year block is your truck as some have a road draft tube on the driver side out of the block and the newer ones had a valley pan tube running out of the back on the pass side

 

Dang. Sorry about not replying back to this. I have since sold the truck, but want to conclude this post.
The body ground strap is at the bottom of the larger picture. I am not sure what year the block is, it's not original to the truck. I thinks it's from a '63. There is no plate on the side of the block.
I think the oil might have been comming out of someplace higher up on the back of the block. I didn't remove the transmission of clutch plate or anything to actually investigate further. Just used a flashlight and looked at the back as best I could.
