Engine/Transmission (1998.5 - 2002) heavy blue smoke

[Wagon]

My dad's 02 HO lately smokes heavy blue exhaust smoke on the first start up of the day, and it doesn't sound like a 24v, sounds like its underwater. After driving slowly for about 5 min BOOM smoke goes away and the sweet sound of the 24v returns. Any ideas would be appreciated. He has Formula injectors in it as well as a edge comp box. Does this with the box on or off. Thanks for looking!

I have an 02, and My truck did the same ,thing here's what I did.

I loosen the bottom bolts of the

exhaust manifold, what I mean is i loosened to of the bottom exhaust manifold bolts at a time I drove for short distance and then let the trucks sit overnight Then in the afternoon I checked for any oil leaking out of the bottom of the exhaust manifold I did this to all six exhaust manifold flanges but only the bottom bolts . I ended up with oil coming out of number six ,five ,four exhaust manifold ports . I took the valve cover off Look at my valve stem seals and number 6,5,4 ,valve stem seals on the exhaust side were crushed And letting oil rundown the valve stems into the exhaust manifold which was creating all of blue smoke at start up . brought it to the dealership for warranty they've replace the valve stem seals and it worked for a short time and then happen again to me it did this three different times.

It ended up being Bad valve stem guides also so they decided to replace the entire head and now no problem since .

It may be easier just to take the valve cover off And look at your valve stem seal's and see if their crushed on the exhaust valve side .

You may do a search on blue smoke at start up And see what you find ?

Also heard of Turbos leaking oil causing the same problem .

Hope this helps good luck

Thanks I'll go look in the morning

Wagon I don't think your smoke issue has anything to do with oil. Since the rattle is gone it has to do with fuel. His lift pump might be dead. . . here is a quick test, easiest to do with a helper:



Get a 2-liter soda bottle and put it over the end of the fuel drain hose.

Have someone bump the starter (but not start engine) and as soon as you hear the lift pump kick in open the fuel drain lever for a moment to see if fuel gushes out.



If no fuel comes out or is very weak, the lift pump is dead.



Another problem could be a badly plugged fuel filter. Also could be a problem with a fuel line leaking and it's drawing air somewhere between the lift pump and the fuel tank. Another possibility is the check valve for the fuel return at the injection pump sticks open and doesn't build fuel pressure.

I thought that it could be fuel as well but its had a fass on it since it was about a year old and its never been run with low fuel pressure. I changed fuel filter on it this summer and there was no debris or water in the fuel canister or filter from what I could see. I was wondering if the intake temp sender could be failing and telling it that its -40 and then come back to life. Could this be possible?

Blue smoke in the exhaust = oil. Ask anyone that's owned a "Smokey ol` MoPar". Now the question is where is the oil coming from? You could check to see if the turbo drain to oil pan inlet hose has a problem. Meaning, rubber hoses sometimes fail internally first, creating a flap if you will (a check valve) that will only allow one way flow. If upon shut down the flap covers the return to pan oil can build up and have no other place to go except the turbo. Upon start up the oil burns through the exhaust until for some reason the flap opens allowing oil to drain into the pan, thus relieving the flow path. Bla, bla, bla, check the hose and then look elsewhere. MHO
