Sorry for some reason It didn't post.
The copper stuff is head gasket spray, don't worry about the over-spray on the pistons I cleaned that afterwards.

That is so true. I put om603 original gasket with copper clue to my car and its still working
I have heard so many time about those om606 gaskets because they just dont work and makes pressure to cooling system almost immediately after first start or after couple days. If you still want to use it, careful installation is the key to succeed. Sometimes they work

(08-30-2012, 03:18 PM)mantahead hi,
has anyone tried a copper gasket on 603 or 606?
what gasket you recommend for 606(standard mls?)
One guy here in finland tried a copper gasket and its much worse than om606 gasket
it didnt work at all. For 606 you should put original gasket. But there is same problem that is with 603 engine. Head and block both need to be extremely straight or gasket wont hold pressure. You could put copper clue on both sides of the gasket to get better chance to succeed.

some people say that the copper gaskets have to be heated and tempered before they are put on.??

I think that he did everything possible to get it working. I am using 603 gasket with glue and it holds 2,2bar (32psi) boost easily. And thats enough to get 400hp/650Nm with hx40 holset.

(08-31-2012, 04:15 PM)mantahead hi,
do you guys run standard compression ratio?
Whats the advantages of lower CR apart from running more boost?
Yes we use standard CR. You dont need to lower it if you arent really building a drag car
bigger and lighter valves and better valve springs are needed if you want more than 550-600 horsepower from 606 but compression ratio is thing that you dont need to worry about.

09-06-2012, 08:02 PM #15Has anyone tried this before me with any success? I glued the gasket down as well as disassembling the gasket and gluing each layer. I can't see why it would not work it works for the 606 with success.

09-08-2012, 03:58 AM #17it doesent work because 603 has "expand" creeks betwen the cylinders wich is the engine coolant water, and some of the compression leaks betwen cylinders and the coolant gets pressurized. 606 doesn´t have those "creeks" so theay usualy to get some leak betwem cylinders but it doesn´t matter on them
