You also might want to send the rod out to check it for straightness. The piston on that number one cylinder was messy combined with the band on the crank main nearest it. Almost like something was not running straight.

The engine might have been hydrolocked for example at some point in the past. I personally would not put any money in until the problem or a pretty good indication of the problem is identified. There apparently was a noise at the top end on the number one cylinder remember. I doubt it was caused by the broken ring.

#1 piston and rod are being replaced... true it is just another used piston but it looks just like all my other pistons i.e. smooth, not all beaten up and the grooves are in decent shape.

update
 
Well, today I replaced the rear crank seal (wow, I am glad I did - the old seal was like a fossilized rock). I also removed the pulley, balancer and all that stuff from the front and will be replacing the front seal. I stripped one of the allen bolts while removing the pulley and had to hammer a 8pt 12mm socket onto it to get it off...

Tomorrow I will put the new seal in and hopefully will find a place where I can borrow a torque wrench that goes up to a gazillion N-m.

To all y'all who hesitate about replacing those seals "while you are in there": IF YOU have them out and see what those seals have turned into, how hard they are and how they crumble, you will be glad to replace them. So, DO THE SEALS!

I also replaced all the rubber parts in the oil drain tube in the upper oil pan while I was doing the rear seal in it...

Oil pans installed.

Head is on, tightening the head bolts as I type (10 min cooldown period before doing steps 3 and 4 90 degree angle torque).

konstan 09-03-2010 12:51 PM

Man, tightening the head bolts is stressful, for a first-timer, at least.

40Nm - easy.
70Nm - also easy.
wait 10 min - piece of cake. Have a cigarette, drink a coke (too early for beer, dont want to get an evil eye from the missus)
90 degree - well, they all turned ok but it was hard
90 degree again - had to get a bigger breaker bar, and I was kind of worried the whole time that I will break something. :eek:

In addition, the last few bolts in the last step turned easier - maybe because all the others have already squished everyhing... hard to quantify, them last bolts just seem to turn easier than the first ones.... so I thought I'd see what y'all say

And yes, I am reusing the bolts, :o and yes, I should've bought the new ones, but after the rings, bearings and all the other stuff the project was getting to be over budget.

But the head is now on, so now I can go and fret about whether I did it right...

Looks good !!!! This has been a long time coming !!! I may have knocked those dents out of the pan while it was off, not that important though.
The motor should purrr like a kitten when you get it back in & running!!!

Good Luck !!!!!!

So, dont worry about the head bolts? Can I check their torque or retorque them or something? Get a life? What's that?

Don't know about those head bolts. It would give me the heebie jeebies too. But probably not the screaming willies.
Pre-dented oil pans give the freedom to hit speed bumps at escape velocity.

The Plan
 
Yes. Thank you all for reminding me why I keep coming here :)))

Here is my plan.

I am going to loosen these last 4 bolts by 90 degrees. Then I am going to torque them to 2nd step (70).

Then wait 10 min, then steps 3 and 4.

So there.

UPDATE: the bolts are all good. Everything tightened up correctly, in sequence, and with the proper torque. I redid the last two bolts just so I can sleep better at night.

On to the camshaft and the rocker arms now.

konstan 09-08-2010 10:29 AM

Yay, the rocker arms are in place and the valves adjusted. Now I need to install the various odds and ends like a/c compressor, alternator, manifolds, turbo, etc.

At this rate, you may have it done by winter !!

That's the plan, my wife wants her garage spot before it gets to be below freezing here.... She's been a real sport about not being able to park in the garage for over a year.

layback40 09-10-2010 09:44 PM

Best you treat you wife well konstan, good ones are harder to come by than good benz's !!

mach0415 09-11-2010 04:44 AM

Yeah, and good Benz's cost less:D
