Anyway to fix burning oil?, Besides getting a rebuild? Options

[Stambo]

After realizing i gotta put a couple quarts in between oil changes. I figured i might start saving for a engine rebuild. I'm only at 170,000m though but i burn oil like no other... Is there any other way to fix that or am i just stupid trying to believe there is a other way.

My 7A started burning oil around 165k. I dealt with it for a long time until it started getting really bad around 190k. I was going through about 3qts of oil every 3-4 days and it smoked so bad out the back, found out later it was also leaking from almost all the oil seals too.

If you don't see that puff of smoke on startup it's most likely your piston rings more so than the valve seals. I figured if I was going to go so far as to change the piston rings I might as well do a full rebuild, so I got a second motor and rebuilt it. Swapped it in at 196k miles.

You could just remove the oil pans and pull the crank and pistons out from the bottom. Problem is that you still have to get the timing belt off to get the front oil pump off the block and the transmission off to get the rear main seal housing off the block before you can pull the crank out. It's so much easier to just pull the whole engine out, rebuild it, then put it back in.
