Pictures as promised.

First picture taken with the engine hanging from the hoist after I pulled and leveled it . Notice how far aft the load leveler is adjusted. I didn't stop to take pictures when I had the tranny angled down about 45 degrees. Too scary.

Free of the car at last... I was surprised by how easily the hoist moved as I pulled it away. See the bungee cord running from the A/C bracket to the hoist? That's all it took to keep the engine from turning.

The empty hole where the engine once was... looks like a job for the pressure washer.

On the ground safe and sound... I was really amazed by how easy it actually was to pull the engine once everything was removed. I had many well wishers warn me to not attempt it yourself, get somebody to help you. With the Harbor Freight 2 ton lift and the Harbor Freight 2 ton load leveler... the actual removal is easy.

More pictures tomorrow. (y)

I pulled mine by myself but I needed someone to help me put it back in. The load leveler that I had wouldn't create an angle steep enough to get the engine back in.

Is there a trick to removing the timing chain cover? I got every bolt out and I can even wiggle the cover in and out but it feels like something is preventing it from lifting off over by the distributor tap off. Is there something there that I'm just not seeing?

Good to see that everything worked out for you. Perfect time to replace the engine mounts. The two small bolts are a PITA with the engine in.

OK... I'm embarrassed to ask this next question but the last time I removed rod bolts or nuts would have been on a 265 Chevy small block. Are the rod nuts on the Mercedes Torx or what? I don't have any sockets that would fit these nuts. What should I get?

The door creaked when I tried to open that memory. Are you sure it isn't a 12 point metric socket? I don't remember it being Torx or a special socket on the 4.5L. They did look like that.

You may be right about it being a 12 point metric socket. I think it's 14mm. Wouldn't you know, I have a 13mm 12 point and a 15mm 12 point but no 14mm 12 point. I do have a 9/16 12 point that fits but a bit sloppy.

A 9/16 is .562 inches and 14mm is .551 inches so I guess it makes sense that a 9/16 12 point would fit a 14mm 12 point but a little sloppy, by about .012 inches.
Tomorrow I'll pickup a 14mm 12 point and see if that does the trick.

Thanks.

I needed more room in the garage... engine parts all over the place... so I put the hardtop on and rolled the 107 outside.
It's amazing how the hardtop completely changes the look of the car.

Wow. Was it a ring that gave up and did that?
No... the rings on #6 were fine. It may be that one of the two times the chain guides broke and took a few valves with it... there must have been something (now long gone) that got lodged in one of the ring groves and beat the crap out of the piston and cylinder wall. None of the other pistons or cylinder walls show any signs of excessive wear although a few of the rod bearings show some wear but nothing excessive.
I still haven't found a reason for the loud ticking sound... which is part of the reason I torn the engine down. It looks like all I can do now is a standard engine rebuild. I'll have the cylinders dressed and re-coated, fix #6 by whatever means the machine shop has,replace the rings, and bearings, do (or have done) a valve job, replace the valve guides and seals (why not?) and put this thing back together.

Time to remove the crank... I took a picture so I could document location and direction of the caps.
The mains have numbers stamped on them 1 - 5 but I want to be sure I get them back in left to right instead of right to left.

Not just the look, but the way t sounds and feels to drive. I put the hardtop on mine last night and have been driving it since, and will probably keep doing so until it's time to put it away for the winter.

As expected the #6 piston is unusable.

I take it it's not supposed to look like that?

That would explain the helicoils.

The block is ready to go to the machine shop for cleaning and to see what can be done with #6.

Here's what #6 looks like from the bottom. Ugly.

Here's 1 thru 4 (picture taken from the bottom). Not bad.

Here's 5 thru 8 from the bottom. That's #6 second from the right.

I should mention that every one of the bearings... rods and mains... all show wear and some scratching. It's obvious that some tiny pieces of nasty shiot was circulating around in the oil. The worn metal on #6 piston and the scrapings from the cylinder walls of #6 had to go someplace. I guess getting trapped under the oil delivery holes in the bearings was as good a place as any.
