2005 T4R v6 engine knock | Engine Rebuild

More bad news... definitely spun a bearing. The crankshaft cap bearings very worn as well.
Engine block and crankshaft may be toast. Very concerned about those deep scratches below the cyclinder wall.
Taking block and heads to machine shop tomorrow.

Thanks man. Learning a lot along the way labeling everything I can.

Drcoffee,
I do get the point you are trying to make but I need the challenge and with the help of this forum, it can be done. I really hope I can avoid the grenade part though.

Ouch, that's a lot of carnage. Good on your for tackling this but personally I would get a used engine. It would always be in the back of my mind that I may have missed a damaged piece.

The damage is fixable in my humble opinion. The crankshaft can be definitely fixed...re-grinding and polishing can be done by a specialty shop and oversized crank shaft bearings can be used.

My vote would be, buy a used engine, replace the timing chains while its out, and get the truck running again.
Keep the pile of bits so you can tinker with rebuilding it and then trash it. If you had bottomless pockets and a full machine shop at your disposal, I’d tell you, your nuts, go buy a used engine. :tea:

This is what I would do as well. All of those bearings are trash, crank is f'd from all of the washout of the head gasket leak, a couple rods are cut/broken??, it's not going to be cheap to fix all of this.
I was not expecting to see that much damage and got completely discouraged trying to continue the rebuild process. I wasn't even able to get the crank out of the block.
The block, heads, cams, pistons, connecting rods, caps, bearings are at a machine shop and they will let me know what's salvageable.
As a backup, I'll be trying to source a motor from pull-a-part in the mean time.
I appreciate all your comments.

Nevermind. After reading this thread, it's probably more headache than it's worth.

Beeze, roughly speaking, what was your anticipated budget and hours for a quality rebuilding with OEM parts? Before and after you discovered the extent of the damage.
3k on a rebuild. Time wise....3-4 hours every evening until it's done.

Have you called any of the salvage yards like Yoda Jim? I think hes out on I76/I270 exchange. Maybe he can get a bead on a lump for you.

What triggered all the failure, is it just bad luck?
I bought the vehicle knowing it had engine knock. Im guessing bad/improper maintenance had a lot to do with it and most likely started with a blown headgasket.

From what I understand, you can't mix v6 engines from 03-04 with 05-09 engine because the both use different transmissions, and also have difference ECM communication protocals. with an 05, an 08 engine on paper should work out
