There were some tapping noises coming from the left bank. So decided to remove the covers and meaure the valve play to see if some of the washers needed replacing.

Found 8 damaged rockers in the right bank (slight flat spot, 3-4 mm wide), some light grooving on the cams (leaving them well enough alone for now), 6 washers that need to be enlarged to 5.45 on the left bank, and equally 3 worn rockers.

Also found the left inner chain guide had broken off. Managed to fish out the offending article and am now driving with the guide part under the inner lower pin missing. Seems to woj fine though, and no danger of loose parts wedging between the chain and the sprocket.

I'm looking forward to this like visiting a dentist out of novocaine.

I have always wondered why we do it! A guy could just go out and buy a nice NEW car and have many NEW modern features and not have to worry about something falling off every time he takes a trip.
I don't get it.
But then, I HAVE driven a few Benzs' from 0-150,000 miles with little more than fresh oil and filters and sets of tires and brake discs too.
I still wonder, late at night, sitting under the stars sipping, just why we do it! LOL

What has caused all that then do you think?
The broken guides are age more than anything else.

I expect the rocker wear is from misuse. I have the sneaky suspicion this car was driven for something like 10 miles every day for 20 years, never allowed to reach optimum temperature. Started cold in the morning and in city, low rev traffic for a few miles and shut down. Same thing in the evening. Combined with a slightly leaky thermostat never reaching above 60C.

The wear on the rockers is uniform. They have a small flat spot (not worn through the reduction plate), and it's across the right bank. Carbon copy, so probably bad lubrication.

I guess I need to find an excuse for a road trip. I only do quick darts around town these days, in essentially the manner you described.

Gutted. That's a lot of effort.

It's partly why I'm more than happy cycling unless going on a roadtrip. The thought of town driving and the wear it causes makes me twitchy. I'm always going on to my friends about the damage they do when they do this.

I know it's not advised, but it can't be that bad... I hope.

I've read in a couple of modern car owners manuals recently, the following guide:

'If you drive journeys of 8 miles or less, 3x per week or more, the owner should change the engine oil 4x more often, or the effect could be that the engine will last only a quarter of its usual healthy lifespan.'

It pretty much fits with what I've always thought, its the condensation that builds up in the oil, think water in the oil and you get the idea. If moving cars about, I will always try to push them first rather than start the engine needlessly.
And since my cars are for my trips home, they have had mainly the long runs to keep them chipper. My little 0.6 litre Citroen 2cv I have had for over 14 years now, it has screamed at full revs on the 200 mile journey home for most of those years, every 4 weeks. And never had to touch the innards, just kept up the oil changes and is in perfect heath, low emmisions, very healthy motor.
The other problem with the short journeys is the carbon build up isn't it.

I know how you feel. I've been working on mine off and on for 2 years now with a big push the last few months. Every weekend and every spare hour I have goes into this stupid car and it's getting real old...but then again it's close to being done so I'm committed to finishing it. In my opinion it wasn't a smart move to do this. At least not for me. It's a LOT of work and a lot of money getting these cars restored and it doesn't make any rational sense considering what these cars are worth. Nonetheless I got myself into this mess so I have to finish otherwise it's just a parts car. Hopefully I'll feel better about it when it's done.

I don't think I would do it again... but then again with the right car, It might go easier the second time.

It's nice to just get in and drive a new car without having to fix anything and have your weekends to do something else. That's what I think every time I drive my wife's new car.

When it's all finished, your wife is going to get in your car, and say " Man, I wish my car rode this nice... " and then you'll know it was worth it.

Actually, my DD is an F150 Raptor. But I never get a chance to drive it, because SWMBO has confiscated it. I can't seperate it from her by any means known to man.

On the subject of PPI's. It all sounds great. Theoretically. Unfortunately reality gets in the way. A few thoughts :

- These cars are 25 years old. Or more. Finding one that doesn't fall apart in our climate is a task upon itself. Finding one with a FSH and low mileage is possible. I actually did find a 560 SEC with a FSH and 50.000 miles. They wanted 25.000 USD for it.
- There's nobody left who can actually DO a ppi on them. Official dealers for the most part don't even have the tools for them anymore.
- These are not rare. They're not worth anything in terms of rarity or desirability over here. The economy is in the toilet, gas is over 8$ a gallon and has been for a long time. People don't want these, except for a few idiots like myself.
- I bought one that had just passed it's road worthiness test 4 weeks before. Paperwork and everything. The front suspension was shot to hell.

The thing with these old Benzes is that, although they were very expensive and generally properly maintained the first 5-10 years, the road tax system and gas prices over here pushed them onto the second hand market in the early nineties for very little money, and they were bought by people who could afford to buy them, but not maintain them properly.

When I started out looking for an old Benz a few months ago, I visited several professional second hand Benz 'specialists'. Just to give you an example : there was one claiming to shift 40-50 SL's a year, and he said he had never heard of the chain guide problem and had never had any trouble with them. Needless to say I walked away.

But I'm happy withe ar I found. I knew there was going to be stuff wrong with it, and I can afford to fix it.
I can also tell you what a fully documented repair history is going to do to the resale price if I decide to let it go. 0.

I know youre right. She already loves it.

I'm sure I will love it too. But it's been SOO long since I drove it, I forgot what it's like. But man, it's been a long haul with lots of twists and turns. In retrospect, I would have been WAY ahead just buying a super nice, low-mileage ALREADY DONE w126. Doing it the way I did it, is simply insane. Taking on the paint job was not practical since I literally had to do it 4 times before I got the results I was looking for. It's close to show car paint (just a few very minor defects here and there). I was at car show recently and I was shocked on how few cars had super paint jobs. That kind of paint job could have cost $10k+ which I didn't have to pay since I did it myself... just my time ... which was a lot.

Once I post pictures (in 3 weeks), we'll see what you guys think. Hopefully that will make me feel better.

I (try) to justify the time and money by thinking how much I'd have to spend to buy a comparable new car. What these cars are "worth" right now doesn't even come in to the equation for me. I keep reminding myself that I'd have to spend $50,000++ to have a new equivalent and every time I drove that new car I'd be unhappy because I'd just be another pea in a pod. The other day I was following 3 identical Lexus, all the same colour. The only people that would stop to admire your car would be that guy that owns the same car. I love standing out in a crowd. That makes it worthwhile.
