I changed my injectors today. still have white smoke/miss sound coming from exhaust.im thinking cracked/broke valve in head or piston. weird thing is all cylinders warm up quickly when u put your hand by each exhaust port. I totally unhooked my edge also. rail pressure is about 7000 psi idling. it goes up when i rev her up.

good news is that believe it or not i totally just didnt waste $3000 on the injectors i put in because my truck starts very very fast compared to before and when i rev her up she idles down like everyone elses truck now. also with doing the injectors and valve set she purrs awsome now.very very quiet except for the fact this other problem i still have....


any have any ideas????

 

Now that have partially blowed 3000 clams, why not take it to a dealer that can diagnois with their starscan. Someone can aim you to a knowledgable dealer in your general area. May be the best 100-200 dollars spendt. But they you won't buy a FSM. On second thought with reading of your equipment, doubt they can sort it out without it being restored to nearer stock.

 

While you had the injectors out a leakdown would have been a good idea.

 

Just look at the first time as practice. Pull the injectors again and use a rubber tipped blow gun and pressurize the cylinders. You will hear hissing out of the culprit. Are you sure you adjusted the valves correctly?

 

yes. i do valve sets for a living. i just dont have time to do my own work because i dont have a garage and its -40 celcius outside right now lol.

 

i wonder what shop will charge for head removal and valve work? I think its my head. Whether its a valve seat or crack along seat/valve.how much roughly for a used or reman head?

 

I would pull the exhaust manifold of the head and start the engine and see where the white smoke is coming from

 

yes i was thinking that. i have a crappy 3rd party warranty that covers engine parts but not injectors. they reiumburse me $2500 a claim. i might go with that and let a dealer/engine shop do it. i dont have a shop. i hate borrowing friends garages all the time.

 

ya it sounds like you have a burnt valve

 

Sell it.

I swear everytime I log on you have another issue.

You have more patience for what sounds like a POS than I do.

Good luck.

 

lol sorry. i think this is the last issue. after this the whole truck will be brand new. also i think by changing the injectors i solved alot of issues i had before. it idles and revs awsome now. just that the valve is burnt. also how much more to get head studs vs head olts. i might get that done now since head will be off.

 

will burnt valve keep engine overfueling? when i moved it out of shop to run it it revved high and wouldnt slow down. is it because excess fuel in 1 cylinder?

 

I would take 200 and go buy a good heater, heat up your garage and start pulling the head. If you do valve work it would be no problem.

I 2nd the seeing what exhaust port the smoke is coming out of, that will at least narrow it down to 1 cylinder (hopefully)

I do still agree, take it to the dealer, that will at least get you on the right path. I know a lot, but my scanner won't do everything the dodge one can

 

i have no garage. thats the prob. ill have to see if i can borrow some ones garage space again. i hate doing that.one weird thing is the truck starts super fast now. i swear with these new injectors it takes half a revolution and shes purring.

 

if i get all the valves done that might cause problems down the road would it not? Because doing all the valves will make the top end very strong and i could possibly start seeing blowby on the pistons then?just fix the bad valve ?
