Used by FAT Performance, European Motor Works and the California Central Coast School of High Tech Stuff. But (IMG:style_emoticons/default/WTF.gif) do they know? (IMG:style_emoticons/default/av-943.gif)


Thats interesting, is that the Locktite pipe sealant in the photo?

No that is RTV... I think I'm going to cough....hack hack...

BTW I use to use the Loctite pipe sealant, but I been using DOW 55 molycoat O'ring lube, which is a grease.



Do you have a supplier and part number on the DOW 55? Nevermind, I had to try a bunch of search terms but finally found it. It is McMaster part number 1325K54

Are the o-rings the same size for 1.7 and 1.8 liter engines?

Oops, That part number comes back as:

Seal and O-Ring Grease, Dupont Molykote 55, 5.3 oz. Tube

It is listed as Dupont. Does anyone know if this is the same as the DOW?

Yes, except for the outer orings on early 1.7, up to eng # W0057460, which use 23.5mm instead of 25.1mm orings at cylinder head end.

So then what is the orange stuff in the picture?


Orange RTV. Generally not the right stuff to use for O-rings. Elliott, however, is quite proud that a Professional Shop ™ used it on the outboard rings on his motor.
