Any suggestions???

This is for my dad's 94 Chevy Suburban with 150,000 miles on it. A while back, he went to change the oil and realized the plug is stripped. He put I believe a one-over plug in and it worked until now when he tried to change his oil again. This time we tried a two-over plug, and a 3-over ... both leaked. Put a rubber stoppr plug in there worked for a day or so and leaked. Yesterday we got a 9/16 - 18 tap and re-did the whole. Bought a bolt and washer, it set up nicely and didnt leak. Today my father drove to work and came back to about a 1 foot diameter puddle of oil. He was only in work for 3 hrs. We backed out the bolt and tried a different washer ... still leaks.

ANY IDEAS .... WE ARE DESPERATE.

 

If it was my truck,i'd replace the oil pan like yesterday.You don't want to give it a chance to blow all your oil on the pavement and leave you stranded someplace.You might find one at a salvage yard cheaper than you think.My local yard has a whole bus full of the things.Make sure you get one for your one-piece rear main seal block though.If you want to get really butch,you could seal your drain plug with JB weld and get one of B&M's drain plugs designed for transmission oil pans.I installed one on my trans and it never leaked.Anybody got a better idea?

 

A little update -

We had a new oil pan put in the burban. Everything's fine.

However, now the plug on my 88 Formula's doin the same thing. I put a Single Over Piggy-Back in, and it leaks very little (drop an hour) but I still would like a new pan.

What are my options? I need one for my '88 L03, that would also swap over to my '86 350 block out of a Suburban. I plan on putting this motor in within the next year or so and would like to swap the pan over when doing so.

Is there such a pan that would fit both small blocks? Any comments welcome.

Thanks,

Kurt

 

well provided that it is ONLY leaking out of the plug, id just cover that baby in gasket sealant and that would be that!!!!
