Re: White/blue smoke after injector change

how far have you driven it?
Do you feel you seated the injectors fully and without pinching any O rings?

Re: White/blue smoke after injector change

Ive driven it about 10 miles so far. As for seating the injectors I tapped them in with a rubber mallet and then used the lower bolt to pull rest of way then torqued them down.

Re: White/blue smoke after injector change

Okay so the hold down bolt does not seat the injectors, you seat the injectors the hold down bolt simply holds them there
You need to drive it ALOT more then 10 miles. It needs to be put under load and driven 30-50 miles in order to purge all the potential air pockets from the oil injection system and fuel rails.
Then see if she still smokes.
Blue/grey smoke should clear up 100% when engine is warm
