A question that I am not sure how to even ask...

If it was running ok before the oil change and the valve cover was not holding the engine oil , then a plugged oil return is not the issue . VDART may have the best possible daignosis , maybe you did fill the trans with engine oil . but really theres really not many places for 7 qts of oil to hide in any engine , i cant wait to hear th outcome of this one

Yea, I agree, as she was running alright prior to this first oil change. But the oil went somewhere.

As for the amount, this is a big block and could hold it, it just shouldn't be put into it. A friend, a shade tree mechanic, suggested that I add kerosine, but I'm thinking it better to pull the valve cover off and see what i can clean before I try thinning things out to dump deeper inside.

Those who have suggested that it will be a mess, I agree and do not look forward to the task, but weather permitting, I'll crack her open and see whether the "candle wax" is clogging things up.

If I can get her open, and if I an clean out some sludge, I'll see what the recommended "sludge thread" suggests before trying the old kerosine ploy. I am concerned about how much that would affect the seals and gaskets in a car this old.

I know that older cars ran on that, but that was almost a century before on a different block, and this one has seen many a year and mile...

Suggestions?
