So my 5.0 burns oil, about a quart every 600 miles. A little background, the car has 70,000 miles on it, compression is excellent on every cylinder, and one spark plug appeared oil fouled. It only seems to smoke on a hard accel or a downshift, this points to rings but it seems wierd that one plug is fouled and all the compression is so good. I was thinking maybe the valve seal on that cylinder, and was hoping to do an H/C/I.
Now this is a gamble, because if I set up my H/C/I and it still burns oil, Ill have to tear it down again to rebuild. I'd like to avoid rebuilding if I can, or tearing down the bottom end. Is there a way to spot bottom end issues looking into the bores when the heads are off (any give aways/hints to look for), or do you have to do a full tear down to diagnose?
