Hey guys.

I have a 2001 Dodge Ram 1500 318 4x4 that consumes oil like a mother. I'm talking about a quart in 200 miles. I got the intakes and plenum replaced with Mopar gaskets but i didn't replace the actual pan. I also put a Mopar PCV as well. It helped but still was way too much. I put a catch can on there to try to retrieve some oil but it seems to go right past the can. There is some oil in the can but not enough for it to over fill. I took my TB off and found oil in the intake. Also on start up, I get a blue puff of smoke which leads me to believe its bad stem seals. But losing that much oil i cant see how bad stem seals could be causing it to burn so much. After the blue puff, I get a thick white smoke until the engine get hot then it doesn't smoke, even at acceleration. Only other time I get a small cloud is if i'm at a light for awhile and a step on the gas a little hard. Any ideas on what I should do first?

P.S. Please don't say piston rings

 

Compression test.

Also, check for oil leaks. It's possible its leaking out the valve covers, and simply burning off on the hot exhaust manifolds, as opposed to making it to the ground.

 

No leaks, I replaced the valve cover gasket that was leaking.

 

That leaves the compression test......

 

What about valve stem seals?

 

Or guides?

 

id start with the compression test to get an idea of how well the rings are sealing. if your numbers are low then repeat the test with a teaspoon of oil in the low cylinders. also a leakdown test wouldnt hurt.

worn valve seals and guides could be part of your cause. typically seals will only smoke on startup unless theyre really bad, same with guides. however if your guides are bad enough, your engine could pull oil right past them with high vacuum.
