Volvo D16 Injector question

you do not have to touch bolts 1-7 if cam was not removed.

 

go from step 3 down. call me if you need anything else

 

did you get the rocker bolt out

 

Wow it's amazing to see some active recent talk on the d16. I don't want to thread jack but want to ask. Have you ever had a continuing problem that the truck every so often will act like the same injector goes bad over and over? 07 d16 535hp. Just put new injector in about a month ago in cylinder 5 again and now two days ago it was miss firing and blowing white smoke and theieing code for mechanical problem on inj5 again. Kept driving and now it's cleared up again. Cups inj and cam all done 1.5 years ago and had inj 5 replaced under warranty 4 times since now it's out of its 1 year warranty :// could it be a sealing problem? How can I diag, any ideas?

Sorry for the length I just been struggling with this long time.

 

So a compression test mechanical on that piston alone I can almost guarantee some kind of bad valve seat or burned valve have seen this few time. Poor man compression test is simple quick remove rockets remove injector take a blower with a big rubber tip stick it in and put shop air in the cylinder might move engine a bit but then just hold for a min and try to listen for air leaks when I remove lower should get rush of air if everything is good if not something is wrong with that piston

 

Gotcha ok, I'll have to give that a try, thank you!
