I pulled and checked everyone of the tubes, their tips and the seals.

 

you pretty much checked everything. i wouldnt send the injectors back, if its runnin good then you probably dont have a sloppy/dripping injector thats fludding the piston and putting fuel past the rings. i would check these things again.
1. injector o-rings (did the injectors fit in tight?)
2. copper washers (you only have one GOOD one per injector)
3. check the fuel return lines. (passages in head are not clogged and lines are not pinched somewhere or clogged.)
4. cross tubes going to injectors ( good clean seats and you fully pushed them inside head and torqued down lines.)

 

The shop I went to checked all of those . There is something wrong with the injectors because they threw the RV275s back into it and the problem stopped. But they wanted $25 each to pop test them I said no to that one and found a place to do it for $40 for the set and they are local. So we will see what's wrong with them after that.

 

I found out what the problem was. Two of the injectors had bad rubber O rings. They were allowing all of the returned fuel to blow by them. I am going to reinstall them this weekend with all new O rings. Fingers crossed they work fine.

 

Here's hoping!

 

glad you found the problem. let us know how it does.

 

Put them in to day and put 200 miles on them. No issues as of yet. $9 in O rings fixed the problem. But $450 to find out the problem not so good.

 

200 miles, where the heck you end up going??

 

You and I put 40 miles on it then I went up to a buddy's house to pick up a puppy he bought from my mom because he could not handle it with a small child in the house. But I only made it half way be for I turned around. We ended up keeping him.

 

Thinking of doing orings on mine soon as well
