Injectors leaking fuel into oil

Shortly after installing 190mm injectors my truck would not start hot. Later I figured out my engine oil was severly diluted with diesel. Truck has now been parked for nearly a year and Im piecing it back together. I was afraid to install the injectors again and risk diluting the fuel because I had no idea were the leak originally came from. So I decided to install them in a cylinder head with new O-rings and feed them fuel with my Air-dog 2 while the head was still sitting on a bench. What I found was shocking. 7 of 8 injectors leak fuel externally from the body of the injector.

Has anyone seen injectors leak from here before? The picture with the screwdriver points to the location all the injectors leak from. They all seam to leak at different rates. There is only 1200 miles on these injectors after they were built! Where would be the best place to send them to go through them, I no longer trust the vendor I purchased them from.

The internal oring could be cut or there could have been dirt or debree when they put the nozzles on and it didnt seal right

MOST of your products... I have your EGR delete and I love it. You shipped quickly, and it fit perfectly. Been running it for 30K with no issues whatsoever.

But I have heard of more than one person being left with 8 paperweights on their desk because your injectors did not work properly at all. Oh, and a engine being completely ruined by some of your 155's, and was replaced with a new engine from Ford by the owner at the tune of $10,000.

On the other hand, I have heard of plenty of people running your injectors without any issues. It's about 50/50.

I personally have no issue with you guys, you treated me great during my purchase from y'all. But I won't be buying any injectors from you guys simply because of the reviews on the forums.

Of course, y'all may have improved your injector design since then, and improved your customer service as well. But based on the past, you do stand behind your products, except your 6.0L injectors.

Re: Injectors leaking fuel into oil

Yes, I did buy the injectors from RCD, in the first week driving one blew a tip off so I pulled the head again to dig the injector tip out of the piston and bought another 190 injector. Shorlty after I went overseas, this is when the oil became diluted, the wife was driving it unitl it she noticed it was getting harder and harder to start and then the truck was parked unitl I came home again. I sure hope the bearings in the bottom end did not get damaged from the diluted oil, I would not be surprised if I have an early bearing failure. I drained over 20 litres of oil from the engine so there was 6+ litres of diesel in the oil.

Im glad to see that RCD posted a response because I did buy the injectors from them, if you guys (RCD) are willing to get these things fixed I would really appreciate it. I have three 6.0s and so far my biggest regret has been these injectors. I did not mention your name in my initial post because Im not out to bash, just wanted to know if this has happened to anyone else and what needs to be done to get it fixed. I would actually like to enjoy driving my truck again, it has been an ordament in front of the house for way too long.

From now on when I install injectors I think Im going to turn the fuel pump on and confirm that none of them leak externally, I dont want to risk ruining an engine ever again.
