I bought the new bolts for the cam sprocket on my M103 engine. I was told by someone that they THINK that this is an angle torque procedure, but they were not sure. I think they get tightened to 12 Nm and then turned 1/4 turn each.

Any arguments? Any clarifications?

Tahnks for the help,

The torque on M103 7mm cam bolts is 16NM. All 1987 & later cars or earlier cars with replacement cam & gear. Not stretch bolts as the later M104 engines use(after 1992).

Larry, BTW, how was the rod thing (bent??) you were worried about. I am assuming it turned out OK. Keep us posted...

M.B. Doc,

Wow, only 16 NM? This sounds awfully loose. I guess when I tighten it up, it will probably feel tighter than it sounds. That's only about 12 foot/lbs. But I'm sure you're right.

Thanks


Jeff,

I have eyeballed everything, and I don't think there is any lower end problem except the rust. It turned out that the problem was not warpage or a blown head gasket. The problem was corrosion between water passage in head and combustion chamber. I've only had this car less than three years, I suppose the previous owner did not care for the cooling system.

I plan on using a straightedge and feeler guages above each piston to ensure that there is not a bent rod before I put on the head. I don't have a depth mic. I really don't expect to find a problem with this, but I would rather find it now than to take that long walk back up the road to pick up the pieces off the highway.

Unless I run into something else, I hope to have it running again this weekend. In spite of the fact that I'm enjoying driving my new Six Speed C Class, I miss driving the manual transmission 124 car.

Thanks everyone and have a great day,
