, I am beginning to agree with you. I had two sets of Stand Pipes and Dummy plugs, so I put the 2nd set in. Same thing happened and a leak was heard around the stand pipe. I put the old one back in and it went in easily and removed the leak.
Having said that: I need some advice. After I replaced the stand pipe and dummy plug with the old set, I didn't hear any leaks around those. I also changed the top seal, on injector #3, and that leak is gone... but I now have a leak on injector #1. Is it really possible? Maybe it is a stupid question. Maybe I should have been more patient and changed the top seals on all the injectors. I guess there is another possibility... The air that I hear coming out of the injectors is a sign that the STC fitting is bad. There is a change in the air leak when I put the IPR closed. What do you think?
I guess I'm going to purchase a new set of Stand Pipes. I have seen a set of seals and washers for the stand pipes and dummy plugs. Has anyone had any experience with those? Is it advisable to use those or simply get a new set of pipes/plugs?
Thanks for all your advice thus far...
Believe it or not, the Motorcraft OEM parts are cheaper than the Sinister Diesel parts....
