My truck had been sittin for about 4 days havent been driving it much since got the 04 it was doin great made a spot for about 45 minutes jump in it again took off went aout 2 miles and noticed the engine seemed a lot louder than usual and sitting at the red lights there is a lot of blue smoke could not get any codes yet but it stills runs great execpt the dead peddle thing is happing again so it looking like the vp at this point but when it went before there was never any blue smoke any suggestions?

after some more checking it is more than the injector pump it has some upper engine noise and when you take off the oil cap there is a LOT of blow by and a lot of blue smoke out of the exhaust so it seems like a lot more serious than i first thought leaning towards possible broken rings or cracked piston.

Could be as simple as a dribbly injector.

Well, if you can call that simple.

you think that will cause that extra blow by?

Check for Diesel in the oil.

Diesel gets in the oil, all the extra has to come out somewhere.

how could tell if it was an injector or not may be compresion test?

phox_mulder

In order to do a compression test on a Diesel, you have to remove the injector.

If you have an infrared thermometer, and the truck still runs,
you can check the exhaust manifold at each cylinder.

If one is noticably hotter or colder than the rest, it is most likely the injector.

Easiest would be to check the oil level, if it is a lot higher than it should be,
fuel is dribbling down the side of the cylinder filling up the crankcase.
Give the diptstick a sniff, if there is Diesel present, you should be able to smell it.

The blue smoke could also be from a stuck injector,
very cold days mine smokes with a blue tint till the block temps come up a bit,
extra unburnt fuel coming out.
Leaky injector would also be supplying extra unburnt fuel.

i will check that next and see what that looks like even when the engine is cold when you remove the oil cap there is a lot of blow and that the part that worrie me and all of the blue smoke and i mean a lot but the engine s running fairily smooth still thanks for the imput im going to keep my fingers crossed and i might get lucky

hauliday,
I had a 2002 HO and changed the injectors. I wasn't sure what I was going to do with them now that the truck is gone. I don't see in your profile that you have changed out the injectors, so I'm assuming yours are stock. If you want to pay to ship these, I will send them to you. They had about 25,000 miles on them.

Replaced pump and it helped some and it seems to be weak still hardly any git up and go and seems to be on high idle most of the time when coming to a a stop its idiling about 950 and just before i come to a complete stop drops to about 800 and when its hooked it to a code reader it says the fuel temp is - 133351.1 degres so i guess the rebuilt pump is bad too and when we try to pull the injectors it broke the puller so i guessed the injectors are carboned up as well
