[VAC] Re: Smoke & Tears

[Weimers]

Bob:   Summit Racing at http://www.summitracing.com/ has a number of nice covers.   Old bent ones that have been over tightened will never seal!   Summit probably has racing type gaskets too.  In my mind, the equipment for racing and heavy towing needs to be about the same excellent quality stuff.     MARC WEIMER Punxsutawney, PA  -  Home of the Groundhog #15767 1963 Globe Trotter 1971 Globe Trotter http://users.penn.com/~mweimer/weimer.html ----- Original Message ----- From: Bob Kiger To: Multiple recipients of VACList Sent: Saturday, April 21, 2001 6:21 PM Subject: [VAC] Re: Smoke & Tears I am 75% convinced that the problem is the bent old valve covers.  So far two professionals have replaced the gaskets yet the smoke proceeds.  I wish one of them would just have told me to get new valve covers. I would rather invest in new valve covers than try to pound out those old buggers.  This has been so frustrating.  Today I drove about 15 miles with my interior bonnet open.  I could see the smoke emanating from the manifold but it gets pretty murky because the fan is quickly dissipating the smoke. I'm going to see if I can locate heavy duty valve covers and gaskets for the 351W. If anyone knows a source . . .

You have the procedure correct, but the cover must start out flat. A hammer and small block of iron will make it that way if it's been warped from overtightening.                                    <<Jim>> Bob Kiger wrote: > > I > My Quick Question is, "When valve or pan gaskets are installed with cork > gaskets they are not supposed to be torqued down.  They are supposed to be > tightened uniformly and snugly?  Then, in a follow up visit, they are > supposed to be uniformly snugged tighter to further compress the gasket and > seal." > > Am I right or wrong.  The shop does not say that I am wrong and are in fact > putting it on the rack soon.  I just need to know if my premise is correct > as a defense in case they get testier :) > > --                        <<http://www.oldengine.org/members/jdunmyer>>                                 <<[EMAIL PROTECTED]>>                                <<lower SE Michigan, USA>>                             <<mailto:[EMAIL PROTECTED]>> To unsubscribe or to change to a daily Digest, please go to http://www.airstream.net/vaclist/listoffice.html If replying back to this message, please delete all the unnecessary original text from your reply.
