kdml Posted May 13, 2012 Share Posted May 13, 2012 Anyone know of a source for a valve cover grommet for the breather for the stamped steel covers on on '65 401 (see picture)? The hole in the valve cover appears to be 1 5/16" and the breather is about 1". I tried by local auto parts stores with no luck. Cars Inc had grommets, but listed them as for a 1" valve cover holeThanksDoug Link to comment Share on other sites More sharing options...

RivNut Posted May 13, 2012 Share Posted May 13, 2012 Mr. Gasket makes the push-in breathers, check with someone like JEG's or Summit Racing to see what they offer. Someone help me here. I thought only the '66 cover had that hole in at the front of the cover. Ed Link to comment Share on other sites More sharing options...

Plus, another hole further back where the breather sticks out... Link to comment Share on other sites More sharing options...
60FlatTop Posted May 13, 2012 Share Posted May 13, 2012 Thinking back to the mid-1990's, I am pretty sure Cars had those in stock. I know I put a new one in.Bernie Link to comment Share on other sites More sharing options...
kdml Posted May 13, 2012 Author Share Posted May 13, 2012 I looked at TA Performance and the only grommet they had for that size hole was a plug, so I could not use the breather.I looked at Jegs and Summit and they did not have anything in that size either. My '65 shop manual shows this as the original setup. A hose connects to the breather and runs up to the air cleaner. I also have a hole further back on the cover for the oil fillI will give Cars Inc a call to double check the sizesThanks Link to comment Share on other sites More sharing options...
RivNut Posted May 13, 2012 Share Posted May 13, 2012 Doug,That sounds like an early California set up. I'm betting that the other 49 states used the plug and a breather that also served as a filler.Ed Link to comment Share on other sites More sharing options...
kdml Posted May 14, 2012 Author Share Posted May 14, 2012 It is originally a California car and the filler cap I have also doubles as a breather. I suppose I could plug the valve cover and the eliminate the hose up to the air cleaner, as I probably don't need 2 breathers on the one valve cover Link to comment Share on other sites More sharing options...
RivNut Posted May 15, 2012 Share Posted May 15, 2012 Clark's Corvair sells reproduction finned aluminum valve covers that have the large breather like you have in yours. In their catalog, they state that the valve cover comes with the breather grommet. Perhaps you could get one from them or get a lead from them on where to get one.Ed Link to comment Share on other sites More sharing options...
kdml Posted May 17, 2012 Author Share Posted May 17, 2012 Thanks EdI have convinced myself that I should just plug the hole as I already have the filler/breather. Also, the hose up to the air cleaner is broken and would need replacement as well, so plugging the hole eliminates that expenseIf I change my mind, I will give Clarks a call Link to comment Share on other sites More sharing options...
