I have a 1997 Ram with the 5.9 and I am losing oil somewhere. Nothing is leaking on the ground and no blue smoke but yet still losing oil. Can anyone help?

 

maybe plenum gasket. very common. do a search for lots and lots and lots of posts. the intake vacuum sucks the oil into the intake and burns it.

 

Most likely the plenum gasket.

 

It could be the plenum gasket like they said. I have been searching for the same problem with my oil consumption and I'm leaning towards the failing plenum gasket which likely the same problem you have. Are you having a engine miss around 40-50mph speed? Set your cruise control around 44mph or 45mph and see if you feel a miss.

question...my friend has the same problem and we changed out his intake to the M1 no oil in nothing yet he is almost 2 qts down at oil change time...any thoughts?

 

How long does he go between changes? All engines burn SOME oil ... some more than others.

 

if its not leaking it, then its got to be burning it. either by sucking it into the intake, leaking/sucking it down the valve seals, or slipping past the rings. i used to just say oil is cheap, engine repairs/rebuilds are expensive. its not cheap anymore, but oil is still cheaper than major repairs. in my old chevy truck after about 200k miles i found that it used less oil with 40w or 50w rather than 10w30 or 10w40.

btw, where did he get his M1 intake ? do you know how much ?

 

he goes about 2500-3000 miles between oil changes...and we both ordered our intakes from mopar

 

Time for straight 30 weight.

 

Thanks to all that replyed to my post!

I did notice something this morning when I was letting the truck warm up there seems to be a faintsmell of burning oil thru the exhaust but no blue smoke. I do know one thing when I first got the truck I did an oil change and drove it for about 820 milesafter that. Last weekend was out getting some gas I had stopped at a light and the oil light came on, checked oil level and it wasalmost 3quarts low (GM's WOULD HAVE BEEN DONE ha ha!) I will investigate the plenum gasket and probably repair it.

One other question which brand of gasket is recomended and should I use the (Chrysler C.C. Cleaner)?

Thanks Too All!
