Not exactly sure whats causing the noise can anyone chime in on this? https://www.youtube.com/watch?v=udqR...ature=youtu.be

That is lower end knock. New engine or rebuild is in your future.

think it'll be fine with a new crank and rod bearings? If i do go get that done ima have them replace the intake manifole gasket it was probably the cause of this

There are so many of these engines in the boneyard, I would let my fingers do the walking, and and go that route......

It'* hard in a video, to determine exactly where a noise is coming from......a mechanic'* stethescope is handy in this situation.....also killing a cylinder one at a time, and listening for a change in the sound is another help, that would direct you to a cylinder.....

The intake gaskets on a SC'er were not a problem, like they were on the naturally aspirated engines......

If you want to drop the pan, and check the crank bearings and connecting rod bearings, and you find a badly spun bearing, chances are, the crank will have to be replaced, and that involves separating the engine from the tranny to get to the flex plate bolts......I'd rather get a low mileage, used engine......

But first and foremost, find the exact cause of the knock first....

I agree with TechII, investigate where the noise is coming from. A spun bearing will cost you at least pulling the engine, a crank and bearings.

I will this weekend i have both days off finally, i was quoted 200$ for labor in tijuana, i live next to mexico for pulling the engine installing new crank and bearings, cheaper than going to a junkyard finding an l67 series 2 then paying someone to install it i dont have a garage or nothing so i cant do work like that on my car, i tried the plug method and killing the cylinders noise never stopped but i will be dropping then pan and keeping u guys updated
