HELP! Violent shake and loss of power!

ssamsom · #1 (**permalink**) 03-05-2011, 04:56 PM

I have a 2005 6.0, it is -17 Celsius let the truck warm up for 10 minutes and left the house. Got about 5 minutes down the road and it started shaking violently at a red light. Loss of power, sounds awful and shakes like crazy!!! Hoping it is dirty fuel filters, possibly from bad fuel?

Truck sounds awful, tow truck driver says it sounds like a rod is hitting something? What could this be? I put in the upgraded fuel pressure regulator spring about 2 months ago and the directions were confusing, could i have screwed it up somehow? Any ideas would be greatly appreciated, thanks in advance.

Ford dealer told me it was a bent connecting rod, it ended up only being a bent intake valve.

What caused the bent valve?

Your guess is as good as mine

gotta say this truck has never had anything for balls and could never keep up with my dad's duramax, thinking it wasn't seated properly when I bought it back in fall and it just got progressively worse?

That doesn't sound right to me. It would take a force to bend a valve, not just air. Something like coolant in the cylinder maybe

. The tampax's are a bit faster, when comparing stock to stock

When I pulled my heads I realized my HGs were toast, and my egr cooler went a few months back so I'm sure coolant was present in the cylinders.

Lucky it was just a valve, and you didn't make a window in the block
