sealant thread, (asked to repost)

OLD POST COVERS THAT INFO

 

 

I can,t believe the stuff I see at times..in the car mags that are SUPPOSED to be articles composed by guys who know what they are doing!!!!!!!

I picked up a copy of one of the more comon, chevy based magazines and theres PICTURES of a guy dipping head bolts in yellow weather strip adhesive to be used as a thread sealant on the bolt threads (its not designed to come in direct contact with oil and/or high heat coolant),and its not going to give the correct tq readings either, and on the next page the guys gooping, GOBS of clear silicone like youll use to seal aquariums or bathroom fixtures 1/4 thick on/around the intake manifold ports, NEITHER SEALANT is DESIGNED FOR or is LIKELY to perform correctly IN EITHER APPLICATION, and WHERE does this guy think all that excess silicone will go once the intakes torqued down????

theres only two high probabilitys, it will flow into the port where it will eventually harden and get sucked into the cylinders or it may hang there causing a restriction in the port, or if it flows down, it gets into the lifter gallery where its eventually going to get into the oil pump pick up screen, restricting or blocking oil flow

i would not let these guys fix a flat tire let alone work on MY ENGINES all I can do is shake my head and wonder who if ANYONE screens these articles

 

always use the manufacturers suggested installation instructions, as some applications or gasket types REQUIRE differant lubes or sealants but heres a rought guide

a few things you should know

 

Ive had the best luck with the extra thick synthetic /cork composite mix gaskets

[1] synthetic oil desolves that yellow 3m weatherstrip gasket adhesive than many guys use over a few months time so you cant use it to glue valve cover gaskets

 

[2]you must use a o2 safe gasket cement like the BLACK RTV silicone cement and you must clean and degrease the cover with acetone or a similar solvent before glueing on the gasket to get the best retention

 

[3]you need to allow at least a few hours to over night,depends mostly on temp. for that black silicone gasket cement to set up before installing the valve covers, and placeing them gasket side down on a table with a sheet of wax paper under them and a 20lb weight on top of each valve cover while the cement sets up is the best way to insure the gaskets stay correctly aligned on the valve covers perimeter

 

[4]a light coat of (PAM) cooking spray on the lower gasket surface keeps them from sticking to the cylinder heads after installation

 

[5] these gasket retaining rings add a great deal to the valve covers ability to firmly hold the gasket WITHOUT bending SHEET METAL VALVE COVERS OR CRACKING CAST ALUMINUM VALVE COVERS AND ARE WELL WORTH THE MINIMAL COST

 

 

[6]doing it correctly the first time saves time and money
