496 bbc, eagle stroker kit, studded etc.. i got this motor for nearly nothing and i have been running it in my DD for the past year or so, never driven hard or for even that long. lost oil press yesterday, yanked the motor and dropped the pan, noticed if i submerge the pickup in oil, spin the pump with the priming tool i have a massive internal leak at the main...pulled the stud out, noticed that the oil galley is now exposed into the hole for the stud and it looks like it blew through in the area that has been clearanced for the piston skirt/stroke...I have a theory that they noticed this when the machine work was done and they fixed it because the are remnants of a brass or copper material in the pan and a slight sign of the same material near the leaking area and i have since checked all bearings/other components and they are great shape so its not from them..my question is, is there any safe fix for this?..or am i looking at a new block?
had same isue with y block,driled oil hole larger and drove steel tube,with hole you could tack the tube in place need some thick tubing and a reamer to get the slight inter fearance fit. used lock tight as wellworked fine on the312 ford
Wow! Way excessive material removal, not even needed in that area. Can you get a bottom tap down the stud hole? Thread the stud hole to the bottom, then run a 1/2" sealed/set screw all the way down to seal off hole. Leaving enuff clearance above it to clear oil and stud..
I had a rod let go in a big cube Chevy back in the day and it cracked the block just thru the oil pan rail/oil galley. Used the thin wall tube repair on that. Block is still in service. In a blown street 55 Chevy.
