I'm new here (just read a LOT) - I bought a 1999 E-350 with a 7.3 recently from a friend, and JUST put a new Muffler (Aero) and trailer hitch on..... (it also has a Striker Power Module on it that was at the time, set all the way up to 5 -
While I was out playing with the cool new muffler to see how much better it ran, under heavy acceleration, it made soft popping sound (from the engine compartment), "Service Engine soon" idiot light came on & it lost power but continued to run - as I was less than a quarter mile from my house, I continued gently down the road, it still responded to throttle, and I even heard a sucking sound when I let off the gas.... (I thought maybe it got carried away on Boost & maybe blew something loose on the intake side)
As i pulled off the highway, it died & would not start, THEN as a couple people helped me push it to the side of the road, I saw a BUNCH of engine oil where it had sit for a few minutes.....
No Rod hanging out or anything, and it seems like the oil came out on the topside of the motor, as the passenger side underhood area is DRENCHED with motor oil and even had oil running down the Grill.
I don't hear any bad noises when it cranks, and it still cranks over fast (maybe TOO Fast?) - but thats about all I have for info now, as it is dark out & I have to work all night.
If anyone has any helpful ideas, or obvious questions for me, I will check back as much as i can till I go to work.
I'm an OK shadetree mechanic, but my diesel experience is very limited and I would appreciate ANY INPUT! - THANKS!!!!!!
