Hey guys, I have a puzzle that maybe you guys can help me solve.I bought a 1988 416 8 speed that has 1200+ hrs on the clock.The engine runs good with no visible smoke but seems use oil at the rate of about a quart every 8 to 12 hours.There are no external leaks that I see.The hours on the engine tells me that its burnimg oil but again no blue smoke.A little black smoke at throttle up but with the oil consumption I see I am puzzled.I am thinking rings in the future but are the magnum series this hard on oil?Thanks in advance for your insight. Luck,JAinVA
