Head Gasket done - no start (1 Viewer)

I would be curious if something is in with the timing chaining bound up

My thought as well. Something small dropped down the cavernous opening at the front of the head and is jammed between the timing chain and sprocket. In which case the OP would still be at the level of disassembly he is in right now.

It could be several things causing the engine to be ( or appear to be) seized, but more perplexing to me is the coolant on top of the head.

What's this? Looks like the head gasket firing ring.

Looks like a strand from a knotted brush...IDK. Remove head gasket and see if it is present the circumference of it.

What is it that looks like sand on the pistons? Is that carbon or what?

Didn't you say you had a Wix or Napa filter on it?

Those are pieces of carbon. The filter was a K&N that I intended to replace with Toyota after I went about 500 miles.

So, I took off the cylinder head and I am getting ready to drop it off at the machine shop.

I then took the block and turned it upside down. Nothing came out from the timing chain area so nothing loose. I looked down at each of the Pistons and I don’t see any issues. What I had thought was a bad piston skirt is just the same angle piece that is on each piston. From what I can tell they all look identical.

Here is the one that I thought was bad.

Once I get back from dropping off the cylinder head I am going to takeoff the timing chain cover. That is where I expect to find something.

Thanks for all the details and updates. I realize it’s a crappy situation for you but a great learning experience for everyone. So far the bottom end looks good so hoping for the best!

Took the timing chain off. Nothing notable. Bizarre.

Nothing in the timing gear teeth there at front?

Well, connecting rod caps next.

Then main caps.

If not there, then a piston broke a ring and wedged it in.

I almost wish there was at this point, but no, nothing. Crankshaft looks fine, bearing caps look fine, all of the oil nozzles look fine. All from visual observation, but they all look the same. I can see pretty good into each cylinder and the pistons all look fine. Nothing looks broken, jammed, etc. It WILL NOT TURN though.

Man, I'm not sure that I want to go further. Part of me thinks now it's time to bring it to a machine shop. Thinking .........

Now's the time to do it. It doesn't hurt to pull them off. Make sure you keep track of orientation and which nut came off which bolt.

Take the rod caps first, do only one at a time. You SHOULD be able to push the piston up into the cylinder with a bit of difficulty. Then push it back down while protecting the crank until it's seated again and replace the cap. Torque appropriately or at least close. Make sure you place grease on the crank when you put each cap back on to make sure there is lube on it.

THen after all those, check the main bearing caps. Same thing Orientation, look for scarring.

Did you have to do anything holding it wise to get the crank bolt off or is it so froze up you just put the wrench to it?

Crank bolt comes off easy. Torques to 420 without turning crankshaft.
