I'm screwed....
Alright, the thing died on me about two weeks ago and I had to get it towed home. I saw a fuel leak when the guy was putting it on the truck, so I replaced the rubber parts of the fuel lines. Then, lo and behold, today I found out everything I wanted to know about Hydro-lock. So, I pull the oil dipstick, and its soaked in fuel, no oil anywhere. I drain the pan....must've been at least 1/2 gallon of gas in there.
Now, I'm pissed. This blower setup is almost done, and now I gotta rebuild the entire engine......

that probably is why your fuel pressure in another post looked bad (I responded) about the hydro lock, before I tore into it I'd change the oil and fire it up..you might be lucky, no knocks I'd take it for a nice soft drive.Good luck.

But what makes you think the engine's wasted? Have you tried putting some oil back in it and restarting it? Bogus had a similar situation occur when (I believe) a FPR failed on him. I'm pretty sure he saved the engine, if my foggy old memory serves me right. I've had diesels come in the shop with so much fuel in the oil that I had to have two drain pans ready to catch all the liquid. On an average system fill of 10 gallons (yes, 10 gallons) on these engines, I've seen double that or maybe even more come out. After I fixed the problem that caused the leakage, they all lived to see another day.

Oh, and of course troubleshoot and cure the problem that caused this!

the kid is right, my FPR failed, dumping fuel in through the vacuum line.
I had 2 cylinders FULL and a crank case with about 3 gallons of **** in it.
That was 14 months ago, and no problems.

I pulled the vacuum line from the FPR, and not even a hint of fuel smell (well, outside of fuel being all over the garage now). I'm guessing I've got some injector issues, but these are brand new FMS 42#'ers.
So, I'm gonna put some new fuel in there, and start troubleshooting this ****er. Any idea where I should start?
(By the way, thanks for all the input!)

We used to have a switch in the cockpit on the big radial aircraft engines to dilute the oil on shut down in frigid temps. We'd pumped gallons of aviation gas into the crankcase oil to thin it as we taxied in , so it would turn over in the morning . after start-up the next morning , we would run up the engines to evaporate the fuel before takeoff. SOP , no ill effects on the engines.

Obviously it was a pretty safe procedure. You fly-boys can't afford to take chances.

Here's something interesting: I've emptied the engine of fuel (drain pan and cylinders), now when I turn the key over to get the fuel system to prime, I get no rail pressure. There is fuel on the plugs, but no pressure. I've also switched out the prom I was running to a different prom (one for 30# injectors instead of the 40 that I was running).

the prom won't effect the pumping action or pressure at the rail.
I wonder if the fuel pump spun a gasket, so to speak, and decided to die by dumping huge volumes of gas...
You need to check the fuel pump and filter.

As I understand it, the FPR is a restricting device...

Not cool! I'm sorry to here about your loss. Maybe you could go with a 383 instead, I saw your blowere for sale in the parts section I hope all goes well keep us posted as to your progress!
Thanks,Matt

Well, he posted his fuel pressure in another post, and if the FPR goes bad he will definetly lose pressure, but not like he posted, which leads me to believe he has some injector(s) not all, but some sticking open.

If it comes to it and you have to get a new engine I found several places to get really good high powered engines. I bet its the fuel pump or the injectors. Possibly both. Its problably more of a head ache than a disaster.
