Partial Hydrolocking

Gavin&Gage's Powerstroke · #1 (**permalink**) 04-05-2011, 02:10 PM

I am being told that my truck has a partial hydrolock due to one or multiple injectors pushing oil into the cylinders. Would the cause of this be the injector o-rings not being installed correctly? Ford says they have to send a scope in to see which one is doing this if not multiple ones. Is this something that happens alot? Thanks

it can happen when an injector is pulled and they didn't drain the oil rails........I've never heard of a cylinder filling with oil from a faulty injector.......

If it was pushing that much oil in then it would be smokin' like a some bit!

As i was driving I heard a pinging noise so I quickly pulled over and looking out the front window through the headlights I saw a cloud of smoke for a very short period of time. After the truck sat for a little while I try starting it but it only gave out a short crank. I then checked the oil and there was barely any on the dipstick. Now back in mid December of '10 I had the pcm, idm, and the injector o-rings replaced and the oil changed. I only put about 3500 miles on it since. I'm thinking that the Ford dealer didn't install the o-rings correctly and the oil was slowly leaking into the fuel system. The oil does not leak in my driveway so it must have went in the fuel.

did you check the fuel filter like we discussed in your other thread?

Didn't have a chance the truck was in the ford garage before I could get to it. It was at my regular maitenance mechanics garage and he had it towed to the dealer.

Anything else I should need to know before I go to the dealer and speak my mind? Other than asking to see the fuel filter which I'm sure they discarded by now. Thanks
