Garage Report
« on: July 31, 2013, 03:56:15 PM »
Some weeks ago my motor head lost one freeze washer while I was driving.
For the first time in 19 years I had to come home with my car on a tow Truck.......
Not fun...

For about 10 years ago I replaced the head with another and then the washers looked OK.

You cannot replace the washers without removing the head.
Note:
Always replace the washers !!

At the same time I have made some service to the valves to.

From an old friend I was able to buy 2 pretty nice Hella Autobahn Horns. Rather rare I think?

Tomorrow I hope that I will have the car back on the road again.

In english they have several names .... freeze plugs, expansion plugs or core plugs.  In german I believe they are called verschlußscheibe.  The specific type that our cars use is a flat concave disc called a "welch plug".  They are inserted into holes in the engine to seal holes that were used to cast the part.

In the pictures that Lars posted you can see them in the second picture down  (cylinder head) .... one installed, one missing.

The M136 engine has a total of 10 core plugs and the OM636 (diesel) has 13.

In Dutch the name is   Vriesstoppen
Dit zijn metalen plaatjes die in je motorblok en cilinder kop geslagen zitten.
Bij de cilinderkop zie je ze niet omdat ze tegen het schutbord aan zitten.
Het doel is dat als je motorblok bevriest deze stoppen er uit schieten zonder schade aan het blok te veroorzaken.
Reken hier echter niet te hard op ondanks de stoppen scheurt het blok meestal toch nog.

The horns are called Fanfare horns. I have several sets of the Bosch type and they sound like the Queen Mary ship coming into port !
