microsvc Posted December 5, 2009 Report Posted December 5, 2009 All of a sudden I noticed an abnormal oil consumption in this 3.1 when all along it never used any more than a pint between oil changes. Generally what can cause this in this engine, what should I be looking for? There is no leakage on the ground and the engine is dry of oil. Thanks for all the replies! Quote
slick Posted December 5, 2009 Report Posted December 5, 2009 Check the side of the engine, below the throttle body. Also check your coolant. Running alright? Quote
microsvc Posted December 5, 2009 Author Report Posted December 5, 2009 Check the side of the engine, below the throttle body. Also check your coolant. Running alright? It runs great. The coolant is leaking from somewhere but I don't know where. Theres some drops on the driveway. Im thinking its a different issue? On the side of the engine? Which side are you referring to? The side with the belt or with the air filter? Thanks! Quote
hotrodolds Posted December 5, 2009 Report Posted December 5, 2009 What he's telling you to look for is the oil pump drive seal leaking and/or the LIM gaskets having failed. Quote
White93z34 Posted December 6, 2009 Report Posted December 6, 2009 http://www.w-body.com/forum/index.php?topic=16325.0 good write up on the oil pump drive seal as for your coolant, check that stupid metal heater line that goes down and around the passenger side frame rail. Also, are we talking 3.1 MPFI or 3100? Please post the year and car that you have Quote
