Engine Cylinder walls of a 1zz-fe in question.
The guy who wrote the DIY oil consumption fix suggests it should be done to seat the new rings. He has rebuilt many engines that I know of, both of my celicas for a matter of fact, I'm rebuilding a 1zz-fed head and a 1zz-fe complete short block for fun and to one day install in my Celica Gt as even after the original engine rebuild (we are assuming worn cylinder walls from being run low on oil enough to have a spun connecting rod bearing) it burns about 1 quart of oil in 3500-4000 miles, which I hate! Funny thing is, city driving doesn't burn any oil where as highway driving is where it burns oil.
Toyota tech with 25+ years of experience suggest that Toyota recommends against honing the cylinder walls anymore and the piston rings are "low tension rings" I have no idea what that means. He has rebuilt plenty of engines without honing and says he doesn't get the oil consumption issue to come back. Tech also claimed that Toyota doesn't mean use break-in oil anymore, I am not sure how true that is.
New OEM piston rings & connecting rod bearings will be used but all the gaskets will be Fel-Pro, as well as the head bolts & washer
My 2zz-GE has MMC coating on the cylinder walls? and if honed can lead to oil burning issue(Celica forums suggested that). We didn't hone the cylinder walls in that car, it doesn't burn any oil at all now after the rebuilt and goes through the full RPM range that is allowed.
What do you guys think? and why please? I would prefer to understand both side of the arguments if possible and please logic only, I don't care for your "I have done this forever and its the best way there is and no other better route" stuff.
