hello, i have a 1987 power ram with a 2.6 that has suddenly started smoking and burning oil. it uses a qt in 5 miles. i ran a compression test it was between 135 and 145. was wondering about the jet valves in the head? any suggestions? thanx

A valve seal broke from age. It would not hurt to get rid of the air valve while in there. They can do this also.
thanks for the info does the head hav to come off for thisQuote:

You would need to make sure the parking brake is on and you set it in gear to keep the engine from turning over. But I would do the air jet valve elimination kit first. It sounds like it's going to be that or an intake valve. Does it smoke more after you slow down to a stop then go again. Or is it bad all the time. You say it's using a qt in 5 miles. That seems like a lot. Or is that what is on the ground?
smokes bad at idle and constant speed or slow down. not much smoke on acceleration. no oil on ground. whats puzzle me is it all started wen i put a new fuel pump on. before that it used a qt between 1500 and 2000 miles. it still runs fine and good oil pressureQuote:

I don't see how the fuel pump could do this.
Does the 2.6 run a PCV? The better fuel PSI could have an effect on combustion which changes crank case pressure. I know the 2.6s have alot of head problems so the best way to know is to yank the head. Bottom ends on them are usually pretty tough.
The 2.6 does have a pcv valve. I agree with. Camoit on the valve seals. If you were using oil before and now your using more it sounds like whatever was starting to fail may now have failed completely. I would pull the exhaust manifold also and look to see that none of the valve guides have dropped.
He would be able to see that once he pulls the valve cover. If there is a valve problem it would stick up or be lower then the rest.
