Working on my Dad's 1980 F150 302 4x4. It had low oil pressure and the ring gear was so warn the starter would not engage any more. I would rather pull the motor than the trans and it about time for a quicky rebuild. We just wanted to replace the rings, bearings, oil pump and timing chain.
The first set of rings they sent the wrong box. They sent 30 over rings well their was no gap after a bunch of filing we figure it out. The next day we got the "right" rings 4.000 STD Sealed Power E251X. There was about an 1/16" gap. Put one of the old rings in it had about an .028 gap I think the upper end of the spec was .020 gap. Far as I know this engine has never been apart.
Anyone ever had this problem? Susgestion? Don't want to overbore.
