Apparenly I have an oil leak in my 4.3. Don't know where it's coming from.
Gets really low after about a month so it's not a huge leak. Don't see any oil from the heads, Valve covers, or intake manifold. Don't smell any burning oil nor is there an oil puddle under the truck when parked. What I did find when looking under the truck was oil covering the oil pan and some areas behind the engine getting onto the cross member and some other junk. Could it be a rear oil seal? I'm using 5w30 mobile 1 synthetic have been for a long time.
I first thought the oil I'm using is to thin and slipping out but my dodge ram with 160K using the same oil with no problems and the chevy has 94K miles.
( I did put 32K miles in a year on it though ) Any suggetions ?

 

Could be the oil pan gasket.

maybe the oil filter is not tight?

 

Most common is the rear of the intake manifold and valve cover gaskets. It is also very common on the 4.3 to burn oil due to bad valve seals.

 

Thanks, Sounds more like the intake manifold gasket as I can't see behind it only the front. I am loosing coolant at a slow but steady rate to but thank god it's not mixing together creating the milky crap that it does.
Ughh, the 4.3 is junk on top of that it has multiple exhaust leaks from the exhaust manifolds and the nv3500 just blows. Boo on chevy for making a wimpy and out dated v6. Now I wish I didnt sell the 6.0 but 4500 for the 2050 I spent for all the parts comes in handy : ) Thanks guys. Big help
