Engine Oil Discussion

Idiot, name calling proves you are a clown. Going off on synthetic oil after someone with a 1974, oil burning in a 225 asks about oil? You have not an ounce of help for the OP. Go back to playing with you dyno.
I dunno what "Rat Bastid" said/ since I've had him on "ignore" status for long enough that I don't remember why, but again judging by the comments that follow the post that reminds me of that, I'm guessing he's up to the same thing he was when I put him on "ignore".
And on the oil burning topic as related to this thread, I've fixed a few that came to me as "oil burners" (not all but "some") simply by replacing the valve guide seals and did so without even pulling the head(s). If you have a compression gauge that clips apart like an air hose, a decent air compressor and the right style of valve spring compressor it can be done with the head in place.
