Not surprising on the sources......

Yep, one of the symptoms of a bad plenum is spark knock. In combination with your "jet chip", (is that a two wire hookup, or something a bit more complex) Spark knock can and will shatter pistons.

 

we havent did a dodge truck engine in a while, but i thought the last one came with pan and timing cover. you just have to put intake on and valve covers, ect. Just asking,

 

Depends on who you get the engine from. Some come with all the tin. Others don't. No biggie.

 

I've only found one company that includes the pan and nothing else, and one that doesn't include oil pump assembly and all others did. I'm only worried about what they do internally. Can easily replace "tin"

 

Just a heads up on the oil pan. If you get a Spectre oil pan, myself and a couple others on DF have noticed it takes a couple more quarts of oil, which is nice.

 

Thanks for the info. My motor will be out so won't be an issue but were you able to put it on, being larger, without moving the motor? I pulled mine without moving anything and its a squeeze still with the grooves on front of the tranny

 

And i pulled my tb and def a plenum leak. Noticed some chunks of some sort laying in there. Magnet couldn't grab em so might not be metal. It kept grabbing the plate instead. What was the check? Plate was or wasn't replaced if the magnet grabs it? Assuming its not replaced since the new one supposed to be aluminum? Is that correct?

 

And was oil covered too, not just the chunks.

 

Thats the thing, went back on with no problem and no jacking the motor. That pan is suppose to be OEM replacement. But it holds more oil.

 

you say you had a gross evap code?

i'd be interested in knowing what those chunks are..

the charcoal canister can disintegrate, but usually it only clogs lines when it does.. what it can do, though, is cause extremely lean conditions, because it starves fuel delivery..

by itself, a lean engine will ping- it will ping HARD.. that by itself could have caused your issue.. but if you were unaware of the situation, and were generating some good vacuum via 2k+ RPMs, there is a chance you pulled charcoal particles into your intake, which in turn fed them to the cylinders..

I'd guess they would just pass, unless there were a helluva lot of them- but if it were that bad, they were no doubt clogging the breathing of the tank- and that would starve fuel, which would cause some hard core pre-detonation, which would fragment pistons in very short order..

as a precaution, I'd be blowing out some vacuum lines, or maybe even considering re-tubing them..
