It was under the bearing in the front journal. Totally unrelated. Probably had more to do with it being drag raced and revved over 7000rpm constantly for 5+ years. It's probably fortunate that we found it when we did, a bare block cost me $210 dollars, the motor coming apart at 100mph plus and...

UPDATE: front cam bearing spun so cam journal and chain were not getting oiled. New cam/lifters/timing set. Oh and almost every valve was bent, they are toast. And if you think it couldn't get worse, we found a small crack in the block, so the block is toast. Now waiting on machine work to...

Just had new paint job, so yeah, it's a keeper.

If they are only slightly bent spring pressure can pull them back flat against the seats. I'm having them checked.

I agree, but Machine shop explained to me why this is dangerous. Valves can be slightly bent, but spring pressure pulls them down flat to seal giving the impression that nothing is wrong. Need to confirm they aren't bent or they will eventually break. Off to the machine shop I go....

Great idea, thanks!

UPDATE: Decided to pull the cam. There is enough general wear to justify replacement, so new cam, bearings, lifters are ordered. there are slight marks on the pistons/valves but they held air before I removed them. Tell me your opinion of the contact marks:

You're right. Just found out they can be re used!

UPDATE: Motor is out of the car. I have one of those hoses that lets you pump air into the cylinder to hold valves up while you change springs. I loosened all of the rocker arms so there is no pressure on the valves and shot air into each cylinder. All cylinders held pressure! Except for a...

Agreed, I was told I didn't need to put thread locker on it, but I think I should have. It came off pretty easy.

Yes, it slipped about 90 degrees and stayed in that spot.

UPDATE: Well here's a new one on me: The cam dowel pin is sheared off and the cam sprocket slipped about 70-80 degrees to the retard side. I think the dowel pin can be replaced, so I'll do that and see if it bent anything. It happened while it was idling, so maybe I dodged a bullet.

Well damn. None of the local parts stores has a leakdown tester in stock. You have to buy it. I'll start by borrowing a compression tester just to confirm that mine isn't broken.

Definitely going to borrow another compression tester before I do any more wrenching.

And what could happen on a gen3 hemi where the plug holes are in the top of the head?

What mistake would that be? I just had it at the track Friday night. It was idling in the garage when this happened.

It was idling when it went, we'll see.

No timing marks. Will have to figure that out some other way. Damper is marked every degree from 0 to 360, but there is no reference mark on the front cover. No, this is a non MDS motor and non VVT.

I have a wooden dowel that I can stick in the spark plug hole and get me pretty close. What exactly am I checking for? To confirm that piston timing and cam timing are suddenly off from each other?

I know this is a Gen3 Hemi, but it should be the same for all motors: Car was idling in the garage, suddenly died. Not electrical or fuel. Removed valve covers, everything is moving. Zero compression on all cylinders. Does this sound like chain or sprocket slipped? It's a ***** to take off the...

Fortunately, there isn't one. I assumed there was one that was causing the issue.

UPDATE: Good news! I am officially an idiot! Well, you knew that already. It turns out I had the in and out oil lines reversed on the remote oil filter. Switched them and I now have 75psi at idle (1400rpm) and 85psi at 3500 which is all the higher I took it so far. Why so high? It's a racing...

Agreed.

Sounds like if I drain the oil and blow air backwards through the pickup, then run an engine flush through it I might be able to use it again. I have to remove the engine to drop the pan, trying to avoid that.

UPDATE: Car has been at the body shop and hasn't been started in 6 weeks. I started it up today and it showed 55psi oil pressure. WTF??

I had my race motor rebuilt. Apparently the machine shop the builder used did not boil the block. Now it loses oil pressure because the pickup screen keeps getting clogged with gunk. I backflushed the pickup tube and it restored normal oil pressure for a while, that's how I know. There are NO...

You will like it! I have a 5.7 in my race car with a carburetor and it's been very consistent. 6.40 @105 in the 1/8th mile and 10.1 @135 in the 1/4. I happen to have a 5.7 short block I could part with, PM me if you're interested.....
