    Please help. Oil leak at head bolt orings, again!!!

    Hey all. Motor just rebuilt. 1170 wiseco kit, 750 oil pump gears. 2000 miles and head bolt oring's leaking again. This will be 3rd repair since overhaul. I am using factory orings. What could be the problem? Driving me nuts.

    When you had the head off we're the bores around the bolts good and smooth? When you replace the orings are the old ones torn or scrapped up? You could try some sealant on the orings them selves, ,maybe high temp silicone
