I have no number stamped on my cam. The only number I have is the cast in one.

928.105.188.0R

It may not be easy to see, its on the flat rear of the cam.

You might be able to barely make out about 11 o'clock on the right cam 174.01

Well rich, I figured I would just respond here.

I just inspected the cams, the casting number on the cam I have is 928.105.188.0R
I am afraid that there are ZERO stampings on the rear faces of these cams, I have confirmed that the cam which broke (and I removed) has a 211.00 VERY clearly stamped into the back of it. Yet these have no numbers like that stamped into them. They have marks from the tool which would have held it. And they have what appears to be a germany stamp on the end of it, but that is all.

My left cam that broke has no numbers stamped, just a SMALL triangle stamping with a letter or number or something in it. It's too small for me to read. I need to bring my magnifying glass out to the garage. I'll post a pic.

Are you saying your broken cam has the 211.00 stamping?

What is a 204.00 cam? Lame times two?:D

That's what I have to run for now.

That would be lame for bank 5-8, a companion to 203.00, US S cams, M28/19-20.

This info from the WSM section 15, should be 3 columns, but that didn't paste.

^cam from a M28/11-12

Then you need another right side 211 cam or you need to swap on both 188's
So they match.

Your left side 211 has a different profile than your 188 replacements.
Look at the specs posted here.

Rich, the casting number doesnt tell you the specific grind. As N2O states they used that grind for both the M28/11 and M28/12 (engine I am working on) uses.
I have confirmed though that these replacement cams I have came from a 1984 M28/12 enginge. Let me know if you are interested in the cam. It may be slightly better than your other cam. How much of an imbalance it may cause is hard to say, but I doubt it would be much.

just to confirm something all the cams I am using are 211.00 cams, but the replacement ones are NOT stamped on the end.

I have so much to learn. I have been working 7 days a week and have no time to do any real research. So what ever I can pick up here is all I have time for.

PM me a price for the extra cam you have. If I can swing it I'll buy it.

211 and 212 are M28/21, 22 Euro S2 cams from 84 to 86, and have the longest, "best" duration, with same lift AFAIK as the early Euro S cam 187 and 188, which have slightly lower duration.

Rumor has it that some Euro S 84 motors used earlier parts, like slightly lower compression pistons with deeper valve reliefs perhaps making them non interference. Switch occurred I think around M28/22 82E 6114 (or maybe thats the ID off my motor, which is the newer style, and the actual number is lower).

I'm just moving past this issue for now. The engine is going together quickly. I installed my 174's in some Bling housing with new seals. The cam sprocket bolts are properly torqued. The belt is on and tension is set and rechecked.

I'll work on getting some good cams over the winter.

Looking good, what did you do to the exhausts to make them look so nice?

It's a zinc primer for Auto body work. Weld through primer. It's hard to find the Zinc grey color now. It will burn off but looks good for now.

Danglerb, your info is correct, but the engine number you list is for auto cars only, or the M28/22 engine, the first 84 euro to get the high CR pistons (10.5:1) was M28/21 82E00597

Rich PM on route.

I couldn't remember where I wrote the number down from, just that it was related to the small relief piston change. I thought itt must be from the engine I took out of my 84 Euro S parts car and put into the Euro 85 5 spd that broke a timing belt and damaged the valves, but I just read your post on rennlist, so nevermind. ;

"The first autos to recieve the high compression were engine code 82E06114 And 82E00597 for manuals."

BTW the set of cams I looked at today are grind 174 (the ones in the pictures) and the casting number matches the part number.
