GR8, still makes the noise without the snout having a belt on it...

Rep, it DOES sound more like the first video, but no where NEAR as bad... the second is just completely different, I can barely hear it from inside the car, unless I'm at a high RPM. I'm currently on vacation on the gulf coast of Florida, but when I get home I'll make a quick video and let you guys hear the issue. I can't figure it out, and now it's just about getting it to a good shop to have someone charge me out the @ss to tell me something small is wrong and they replaced it, as well as 4 other "notquitebrokenbutwillbeinthenext100thousandmi les" parts that I didn't need. We'll see what happens.

Mine sounded like that first video when I spun a rod bearing. It started out as barely noticable and only at higher RPMs. Over the next few days it got louder even at idle.

Alright SS... IF that were the case and I spun a bearing.... am I still in the same boat financially? Cheaper to get a whole new engine, rather than tear the heads off and pull the block apart to get to/replace that one bearing?

if you get a new engine it will probably cost more than a rebuild...if you get a used engibe you never know what it has been through or how long it will last.

a rebuild imho is the best solution if this were the problem....rod bearings,crank bearings,rings,line honing,cyl bore honing and labor at a decent machine shop shouldnt cost more than a used engine with 70000 miles....you do the math lol

You can pick up a used L67 for as little as $500-700 depending on the yards near you. Ed Morad sells them too. A engine rebuild would be more than that, from what I've seen.

your right...figured they would have been more....what you think a compleate rebuild would cost? 1600.00?

I would look for another engine and do a direct swap if it is internal.

Rebuilds are not as cheap, and not as reliable as a untouched factory bottom end.

It takes a good mechanic and a good machine shop to be able to rebuild one of our 3800 and not have a failure 500 to 10,000 miles later.

If its a broken flex plate, thats easy to see or find, climb under your car, and remove your cover and shine a light up in there and look for cracked, bent, or broken metal pieces. You can replace the flex plate with both the motor and the transmission in the engine bay, you separate the motor from the transmission and sorta push it to the side as far as it can go, there will be enough room to get in between the block and tranny to remove the bolts and the flex plate for the swap. Thats how one guy did it in the pits at the Pontiac Nationals a few years ago. Oh, and you have to use a engine hoist/cherry picker to move, support/hold the motor while your doing this replacement this way.
