Thrown a rod out the block!!!

Props Al +1.
evovin: When you checked your compression, and found #4 low, did you pour a bit of oil in through the spark plug hole and re-check it? That would tell you if the compression was lost in the rings/cylinder walls or through the valves/valve guides. What does the #4 piston look like? For it to break a rod, my guess would be a problem in your valvetrain and maybe you hit the piston with a valve...It could have been a partially cracked piston, and a piece of it finally broke off, seized the cylinder and thus breaking the rod...

all my mods are in my sig."stock head"
No no no
I was saying, that if you had compression problems in #4, it could have been a cracked piston. It wouldn't necessarily matter what rpm you were at if the crack grew to a point where a large piece broke away from the rest of the piston, seized the piston thus breaking the rod.
When doing the compression test on the low #4 cylinder, and adding the thimble of oil down into the cylinder...if the compression #s rise, then the problem is in your rings/cylinder walls, if it doesn't, the problem lies in your valves.

Al I couldn't have said it better myself...well I tried it just didn't come out quite the way I wanted 
. But you hit it right on the head...which is real honest individuals getting turned down for legit claims when there are other yahoo's out there running every bolt on and not even tuned then think they deserve a new motor after 150 drag passes. In the OP's case it doesn't sound like his actual fault but the previous owners. In any case I dont think his will be warrantied.

looking for an engine....I found one for $4800 without intake and exhaust manifold with 20,000miles(from 03 model)---<<<is this a good deal? but im still looking just to have an option. If i can avoid 03 model...it would be great! pm me asap!
