$$$ for Timing Chain Work

I have a 1980 450 SL. How much should I expect to spend at a highly qualified shop to have the timing chain replaced? Also, when they do the timing chain, are there other things that they should do while they're working on it?

Thanks,

They should also check the cam sprockets for wear, and the plastic upper and lower chain tensioner parts should be replaced "as long as you're in there."

If you do replace the cam sprockets, please contact me as I'm collecting worn used ones to experiment with, and will pay something above shipping costs for another pair (and the old double row chain). My email address is my350SL@yahoo.com

ya, do the guides and tension while your there.
I did the chain on my 450 several years ago. The replacement chain has a master link. So you secure the old chain to the spockets with some plastic zip ties, then cut the chain (don't let the chain slip). Use the master link to connect the two together. Hand crank the engine to snake the new chain into place.
It took me about 12-14 hours, so I would think a shop could do in 2-3 hrs.

Treat yourself to cam oil tube kits as well.

DZLPWR, you're underestimating your own ability; the shop's faster, but not as dramatically so as you thought.

My indie shop did the timing chain, upper guides, cam gears, tensioner and valve cover gaskets. Parts were $493 and there were 7.4 hours plus a few miscellaneous small charges; total $1033.

I thought the 450SL had metal guides, but then I don't have a 450. My experience is with the 5.6L engine, but I'll assume the 450 is similar in this regard.

Certainly have the upper guides checked and/or replaced. Replace the tensioner. Should also replace the cam oilers and valve cover gaskets.

How many miles on it and has the oil been changed religiously? There are lower guides to be concerned with, but with regular oil changes, they could last 250k+ miles. They are also a bear to get at.
