Here's the deal.. replaced my head gasket.. 01 24 valve cummmins.. idled fine.. went down the road all of a sudden it started missin and it has whitish blue smoke that is raw fuel coming out exhaust..

 

Could possibly be a Push rod that didnt get seated well in the tappet. Go ahead and pull the valve cover and look for the issue and we'll all give our opinion.

Things that come to mind are:
What was the Valve lash set to?
Are you sure that you got the pushrod in the tappet (were you able to lift the tappet a bit with the pushrod?)
Valve bridges installed correctly?

It's always a good idea to spin it over by hand a few times to make sure everything is seated good.
It could also be that HG leaking

 

HG not leaking..
valve lash to spec..
bridges installed right..
this is my 4th time doing this repair maybe the other 3 were just luck but i dont know.. just pissed... trying to figure it out..

 

Dont feel bad bud, thats the way it always goes. Keep ya head up
Really the only thing I know to say is it would most likely be a valvetrain issue but you'll have to pull it apart and check. IF it's not that theres a list of things it could be.
If you need help give me a call!

 

I'm REALLY REALLY hoping i just adjust the valves again and she'll purr... it surely won't be that simple..

 

it never is...and when it's 9PM and all you want to do is never see the truck again....it makes it that much worse.

But I've got faith in ya! I'm sure you'll get her fixed up right!

 

The worst part is knowing i dropped 12 grand in it just so it will break down all the time.. ha ha..

Problem solved.. the piece that goes from valve to valve... bridge maybe??? came off..i do believe this is the first repair i've made to this truck that didnt cost anything

 

Good deal. Going to close the thread. If the problem comes back, can reopen the thread.
