Something to do with bombing through a puddle and hitting the submerged rock in the puddle. I used my deductive reasoning to figure this one out. Anyway, is there something I can patch the aluminum pan with that will hold for at least a while? If I replace the pan, I have to pull the engine!

If it's fairly small, drill it out and tap it for a tapered pipe plug- - - -lots more likely to seal than any sort of patching compound since it will be impossible to get the oil to stop dripping and keeping the epoxy from sticking. If it's a big hole use a scab patch of 1/4" aluminum plate, a piece of rubber gasket material, and a bunch of sheet metal screws, and be prepared for a few slow drips.

Years ago I had a old Starcraft boat that I fixed up for deep sea fishing off Calif. It had a Mercruiser "Iron Duke" 4 cyl engine. A hole rusted thru the bottom of the oil pan, and I fixed it with a patch of duct tape and a gob of JB weld. I let all the oil drain out of the pan for a week and then cleaned the area with acetone, and then applied the duct tape and JB. The tape held the epoxy in place till it cured. It worked great, and I caught many more Albacore and Yellowtail with that old Starcraft for many years., sometimes as far as 50 miles off shore..... | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | What year Blazer and what engine? Also, 2wd or 4x4? The S series 4x4 isn't too bad to pull the pan from, once you pull the front axle center section out, it's fairly clear to get to it.
