Engine porn!  WOW great job!  Where are you getting the parts?

[rumb]

I buy most of my parts from http://www.mbpartscenter.com/oe-mercedes-benz/1167250125

The plating I do some myself, and I just took a large batch to a local company.

Received my pin puller and got the tensioner guide out. As you can see it is crumbling on one edge.  got it just in time!

Wow, that is nasty! What's the mileage on that chain?

[rumb]

Hard to say, the odo stopped working in 1991 at about 86K miles.  The car lived in Nevada and was subject to high heat most of it's life.

BTW  here is the pin puller I got,  it works very well.

Took my driveshaft to get balanced because when I removed it from the car, the 2 shafts accidentally  got separated.  They said they could not balance it because the splines were too worn.  I did notice the big nut was somewhat loose before i removed it.

anyway my spare shaft seems tight there, so new center bearing and support ordered.

It's funny.....I STILL have people that tell me I'm wasting my time replacing timing chain and chain rails at 100,000 mile intervals.  I suppose the joke is on them, huh?

On other forum someone was adamant that chain never had to be replaced because there was no specific literature that said to replace it every X miles. Insisted that you should just keep changing offset cam keys.

Until KABOOM! Like cholesterol, the silent killer unless you count the timing chain "death rattle " which I'm sure most folks ignore.

There engine is back together with all it's new plated parts, new timing chain and guides, valve stem seals and valves adjusted.

Just painted engine bay today, next week will respray undercoating on bottom of car, rebuild driveshaft and start assembly.

First picture is what I started with..


*somehow the images are reversed - not a new engine configuration!!!
