Looks like there was a leak between the 2 middle cylinders piston tops are nice and clean.

Left cylinder does not look too good oil possible ring issues?

Honestly I can't tell where it let go. Cylinder #1 is full of crap and plugged up, maybe a piece of the head gasket is in there and sealed it up. It was late last night so I stopped.

I don't see a mark or split in the gasket where it went, maybe after it's clean I can tell better. After the head is cleaned I'll check it with a straight edge to see if warped or not (fingers are crossed).

Based on the amount of smuck in the holes I'm worried about the condition of the lower end. If the head is straight I'll pull the pan and check the bearings. Otherwise I'm calling the junk yard for another motor.

If you can't see where the gasket blew that is a bad sign. The head could be cracked or something more serious. With what I see a good used engine would be the way to go. There is a good used engine place up here by me in Ayer that has warrantied any issues I have had.

I purchased a motor for an Explorer installed it and it had a noise. Turned out to be a broke spring. I sent them an invoice for 300 bucks for parts and installation and they sent me a check. The motor now has been in there over 100k still running strong.

I cleaned up the head, put a straight edge on it and it's warped. The block looks good so now the question is should I put a head on it? or swap the motor. I'm leaning towards a new cylinder head.

Get a head.
Odessa cylinder head on ebay was cheap and shipping was free.

One thing I would check is for any casting flash in the coolant to head holes in the block. I know on my Escort some years back there was a blocked passage in the deck. This was causing the head gasket to pop in between 3 and 4 cylinders. Punched it out with a screw driver no problems after that.

$255 free shipping.

Here's an update.

I purchased a new cylinder head and went with the aftermarket version.

Finished putting the new head on two days ago. Hit the key and it fired right up, it didn't even really crank (fired up that fast, YEAH!). I didn't have any antifreeze in it so I just shut it off. Yesterday filled it with straight water, hit the key and it fired right up again but it started to smoke like no tomorrow (I was getting nervous). After 30 minutes or so the smoking stopped but I found a small water leak. I thought it was coming from the joint where the radiator inlet pipe and cylinder head join. So I drained the coolant (water), pulled out the pipe, put some RTV red on it, filled with coolant this time and tried again. Only this time it started leaking worse, arggg! Instead of pulling the lower hose to save the coolant I started by pulling off a hose from the radiator inlet pipe to the overflow / fill tank and it starts leaking again. Since the engine wasn't running I could get in there to look and found the radiator inlet pipe has a hole in it. I'll bet this is what caused the motor to overheat / fail in the first place.

I'm off to the junk yard tomorrow to hopefully find one in good shape.

It's amazing how much stuff can be in an exhaust system after an "incident" and how long it can take to cook out. Sounds good so far, hope it's a quick fix on the coolant leak and away you go. Clay
