crazyhandlz Posted March 8, 2018 Share Posted March 8, 2018 My son has a 1993 subaru loyale, i think the motor has seen better days, replaced head gaskets, took care of over heating but is still burning oil. Wondering if we should replace piston rings or try something else ie: engine swap? If so cheapest fix? Quote Link to comment Share on other sites More sharing options...
MR_Loyale Posted March 8, 2018 Share Posted March 8, 2018 How many miles on the engine? Quote Link to comment Share on other sites More sharing options...

DaveT Posted March 8, 2018 Share Posted March 8, 2018 How bad were the overheating events? I had one that experienced a pretty bad overheat - about a gallon short on coolant. It burned oil like mad after I resealed it. I just ran old oil and cheap oil through it for the rest of it's life. Like a quart per tank of gas. The only reason I stopped running it was one of the heads eventually cracked so the coolant would leak out the exhaust port. Quote Link to comment Share on other sites More sharing options...
crazyhandlz Posted March 8, 2018 Author Share Posted March 8, 2018 Overheated almost immediately. Changed head gaskets and took care of the overheating, but oil is needed after almost every time its driven. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 8, 2018 Share Posted March 8, 2018 Rering it. GD says don’t hone it or you’ll have issues. Or get another block. Quote Link to comment Share on other sites More sharing options...
Dee2 Posted March 8, 2018 Share Posted March 8, 2018 Have you done any tests on it -- Compression tests? vacuum tests ? Is there a lot of smoke from the exhaust when you drive or a pool of oil in the driveway ? 1 Quote Link to comment Share on other sites More sharing options...
crazyhandlz Posted March 9, 2018 Author Share Posted March 9, 2018 Low compression on all cylinders, white smoke, no oil visible. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 9, 2018 Share Posted March 9, 2018 White smoke should be coolant. Watch the level very closely. Quote Link to comment Share on other sites More sharing options...
crazyhandlz Posted March 9, 2018 Author Share Posted March 9, 2018 Coolant is perfect, no leaks. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 9, 2018 Share Posted March 9, 2018 Not looking for external leaks - Don't just check by looking at the level in the recovery tank. Other possible cause of white smoke is only if it has an automatic transmission. Vacuum modulator. Look for ATF in the vacuum line down on the side where it connects to the modulator.

crazyhandlz Posted March 9, 2018 Author Share Posted March 9, 2018 It is a automatic,ill check the ATF. Quote Link to comment Share on other sites More sharing options...
Dee2 Posted March 9, 2018 Share Posted March 9, 2018 I agree white smoke is not normally burning oil. If you're getting low compression, did you try doing a wet/dry test ? I also recommend a vacuum test to check to confirm if the low compression problem is rings or valves. Quote Link to comment Share on other sites More sharing options...
