Doesn't that new timing cover looks so much better than one that you can only get about 80% clean? Aluminum gets a certain patina to it after a couple years, but I suppose you could spend an hour polishing it.

.... And that was for the neighbor. He was a bit impatient to get it on the road, so we cut a few corners where possible.... Like not cleaning the bolt heads. (At least he let me clean the threads on the wire wheel!) But on the flip side, he was all on board with going with the ARP head bolts.

By the way..... Regarding OEM versus aftermarket.... He went with the Dorman harmonic balancer. Quite a bit less than genuine GM, and hey, making one of those isn't rocket science. And that's one of those things you run across while you're in there, in this case he had a nice groove from the seal on his OEM balancer.

I want to say it could be done for around 1100, but I do a lot of other stuff when I do AFM deletes. Like new water pump and hoses, machine shop work on the head. New radiator. If the starter looks original, that too. All new sensors. Just under $2,000 to be thorough and really refresh things. Obviously not necessary, but better in the long run of course. And it depends if you plan on keeping the vehicle for several more years, and want it to be trouble free.

There's a solenoid on the front of the timing cover.

Then you have the actuator that goes through the camshaft pulley and threads into the camshaft. Some websites listed as the camshaft bolt.

Welp. Lifter collapsed and quit. Might be doing an AFM delete now but not sure where to go from here

Yes, may be the valve stem stuck in the valve guide, dropped valve seat, or broken valve spring. Hard to tell from that camera angle.

Here is a bandaid:
I’ve thought about this. Realistically how long could said bandaid help? I know it’s hard to tell but right now is definitely not the best time for me to have to do a tear down or AFM delete

Edit: the video probably answers this lol im going to watch it

while I think this is a worth while try for most and I'd totally try it on mine before taking it apart. if you look close at his first video. I think his valve spring is stuck down more than lifter stuck.
I might as well give this a try.

If I rotate the engine, would a stuck valve mean that the valve spring won’t move? As opposed to a collapsed lifter the valve spring will still move? I just wanna make sure I know what im looking for
