"just rebuilt 1987 454 Crusade
"just rebuilt 1987 454 Crusader , reverse rotation, and it suffers from ridiculous oil consumption.(lost 2 qt. on a 20 mile ride @ 2000 RPM's)
machine work was done by a reputable shop, bored 030 over new crank, and heads were done i was assurede the deck had minimal material removed and that the heads were "just touched to clean them up. the heads have all new parts, guides ,valves and springs and seals.
we can not find any immediate faults, the engine starts fine, temp and oil pressure is good compression is about 150# but it uses way too much oil.
theres no oil in the bilge or on the water and the oil cooler pressure tests ok, the motor does not have any PVC valves on the valve cover just two hoses up to the stock flame arester the same way it was before it was rebuilt and I had no oil issues then, the port side motor was rebuilt by the same shop and has no issues and is set up the same way, we replaced the intake gaskets thinking it had a vacuum leak with no luck
any ideas?"
