Hi, Silicone wipe on, and no excessive amount, will not cause any regrets. Just do not apply more than a coating to a paper gasket. Racers need to remove and reinstall a awful lot of parts and often reuse some gaskets, successfully prepared with black lightly applied silicone. Foolishly apply a bead to glue parts together and I have seen oil pump screens 80% blocked by unknowing fools, with disaster to engines. I am a long time engine builder. I sent my 1990 F250 95k miles plow truck to Chicago Differential for a rear bearing kit and $600 as a fair price requested synthetic gear lube. 500 miles later I chose to pull the cover and change gear lube after break in; No synthetic and 1 hour to chisel off the cover after the shop gobbed on a pound or more of what resembled tar. I reassembled it with a paper gasket and black silicon 2 years ago, just a proper coating. I stuck to common 90 wt. I follow myself often and want the next mechanic (old school) to recognize proper service.

This is especially important when dealing with the oil system and it's many small ports that can be completely plugged by silicone and some important (and typically expensive) part will be destroyed, Good luck - Larry T (67 MGB, 74 911, 78 240D, 91 300D) www.youroil.net for Oil Analysis and Weber Parts Test Results http://members.rennlist.com/oil PORSCHE POSTERS! youroil.net Weber Carb Info http://members.rennlist.com/webercarbs . ----- Original Message ----- From: "EDWARD DENNIS" To: "Mercedes Discussion List" Sent: Sunday, November 18, 2007 5:04 PM Subject: Re: [MBZ] Losing coolant, somewhere > Hi, > Why not silicone? > I did an 82' 300sd 120k miles water pump replacement with a gasket > lightly coated with permatex black silicone. as I always do on this type > pump with gasket. > I switched from the soft brown non-hardening type for removal is easier > with the silicone. > Non-hardening does not mean it comes apart.
