I installed a set of RV275's about two months ago. follwed Mike's instructions here and the install went well except for some weeping at the head. 3 of them at first and they just progressed to all of them leaking and not weeping. Also my return tee was leaking and I put new orings in it about two weeks after the injectors. In my infinite wisdom i did not even think about the bolt on the back of the head:doh:. Dont know why I just did not. Well it was still leaking and getting worse. So I went home this week end and tore it all apart and re did everything. This time I loosened the injectors and tightened the crossover tubes first and then tightened the injectors down.It is all back together and its time to start it up. I am looking at the engine realizing I now have to loosen some of the injuector lines to get it started.:pray:I loosened 1, 3, and 4 and satrt her up, smooths out and runs great. Let her idle for 5 or 10 minutes and sure enough 1, 3, and 4 weeping some. I tightened them up alittle more and went for a ride. Drove her easy and hard for 8 or 9 miles came back and still had some weeping but less. Afraid to tighten them any more that is tighter then i ever did them before, but it helped.Also took the return line bolt out of the head and it appeared the washer on it were just flat washers. Put on new sealing washers and reinstalled the returns. return line is leak free. I looked athe old washers alot closer and could finally tell they were sealing washer, but evedently the head had cooked them hard.Any way I had to get back to Tennessee. Stopped once for fuel after 200 miles, opened the hood 1 is dry 3 is barely moist and 4 is weeping slightly. Drove the next 220 miles to the campground, opened the hood and all six are dry. Shut the engine off and looked a gain and 4 started leaking ever so slightly. Well I guess i will just have to keep an eye on them. Will be doing mostly in town stuff the next couple of weeks and maybe they will stop altogether.If anyone else has had this problem and found a sure cure I would love to hear about it. I am still pretty happy for now, I am almost 100% leak free.

I have a friend that's looking at an 01 dodge cummins and he's asking me some questions. Now he says it has a fuel leak on the vp44 behing the inspection cover. I think he means the cover that has the tamper proof screws holding it. Is this a concern or can he just change a gasket or seal and not worry about it? It also has a cracked exhaust manifold so I suppose that means it's been run too hot. Any concerns there?
