R107.042 M110 Engine question
 

I am working on a 1985 280SL Euro for a friend of mine. I have been working on Mercedes for over 34 years but I normally don't do heavy engine work. That was always my brother's specialty but he passed away a few years ago, so I am stuck with this repair. I prefer interior work, restoration stuff, general maintenance, etc. (Anything but heavy engine work). Anyway, the engine on this SL was overheated and blew the head gasket. We pulled the head and had it sent out for repair. The machine shop did an excellent job, now it's time to reinstall. I have done a search on here and the google machine and can't seem to find the cylinder head torque specs. I did find specs for the older M110 engines with the standard head bolts. I believe these are stretch type head bolts because they use the spline socket instead of allen head. Does anyone happen to know the specs for the head bolts? Any help would be appreciated. Thanks. CF.

Give me your e-mail i'll send you all the info you need.

Thanks for the valuable info daddi. I will be glad to get this car out of my driveway. I hate engine work. That is why I have had the car over a year. I told the guy, if he wants his car back, put on some old clothes and get your arse over here to help. He is on the way, wish me luck.

Thanks everyone for the information. I haven't put the head on the car yet. We spent Sunday putting the head together. We did a lot of cleaning then installed the intake and exhaust manifolds and the cam tower. Next Sunday we were going to set the head on and torque it down but I just found out I have to work...crap-o-matic. Not sure when we will be able to get back on this project. I will try to keep you up to date.

Normally, if you buy a head gasket set, they give you the torque specs right on the packaging.

I found that out when my friend got here Sunday with the parts I told him to get. He originally said the specs were not included but as it turns out they were in the package.
