So, from what I gather, there are a few techniques listed, provided;
A-All surfaces are better than 50Ra, and flat.
B-Surface areas are clean, dry and oil free
C-Retorque after one day or as long as possible
D-Seal the threads of the bolts, obviously
The techniques for Cometic ML HG installtion are listed as;
1-Install dry and "as is" (Per Cometics website )
2-Remove rivets, coat all layers with copper spray, assemble in order, add GM seal tablets.
3-Remove rivets, coat only inside layer on both sides with copper spray, assemble in order, add GM seal tablets.
4-Remove rivets, coat all layers with GE1200, assemble in order, add GM seal tablets.
5-Remove rivets, coat inside layer on both sides with GE1200, assemble in order, add GM seal tablets.
6-Remove rivets, coat all layers with thin coating of silcone sealant arond the water passages and section to the lifter valley, assemble in order, add GM seal tablets.
7-Remove rivets, coat inside layer on both sides with thin coating of silcone sealant around the water passages and section to the lifter valley, assemble in order, add GM seal tablets.
8-Remove rivets, add a very thin coating of silcone around the water passages only and section to the lifter valley, add GM seal tablets.
9-Remove rivets, add a very thin coating of silcone around the water passages on all layers, and only and section to the lifter valley, add GM seal tablets.
10-Remove rivets, coat all layers with HYLOMAR, assemble in order, add GM seal tablets.
11-Remove rivets, coat only inside layer with HYLOMAR, assemble in order, add GM seal tablets.
So, which one worked for you to get a leak free installation?
Anyone try Permatex adhesive sealant between the layers?
