My 68 has a 468 that is using oil. The previous owner, who had the engine built, said it never burned any oil when he had. He is a true old friend and ultra honest guy. I trust what he says about the engine's past.
The engine has TRW forged 9.5:1 pistons, chrome rings, Harland Sharp roller rockers, solid lifters, Lunati medium cam, forged crank, etc. It has about 9000 miles on it since it was built in about 1992. The owner didn't drive it for the 2 years before I bought it, but he says he used to start the engine in his garage every once in a while to keep things lubed. He drove it for a thousand or so miles with conventional oil, then switched to 20-50 synthetic Amsoil for the 8000 miles before I bought it. I am using (and I mean USING) 15-50 Mobil 1. He ran the engine at about 170 degrees, I have it stat'ed to run 195. It is a waaaay strong motor.
We just did a longer drive, about 220 miles highway and 30 cruising around town, all mellow driving. I got home and saw that the engine had gulped a quart of oil.
I do get a puff of smoke when starting, but nothing obnoxious. I was following it in another vehicle, and there is no noticeable exhaust smoke.
Sooooo........what happened from the time the guy ran it and it didn't burn oil, until it sat for a few years and I bought it? Could the rings have gummed or something like that? Would Marvel Mystery Oil free them up?. I have done probably 15 full throttle, 6000 rpm blasts up the on-ramps, but that surely couldn't eat the engine that fast, could it???
Check out http://members.aol.com/kengibbons/auto/index.htm It's really embarrassing for a car like this to "huff" (Utah vernacular for burn oil).
Any thoughts? Thanks!
