NQ You have a very eloquent way of stating things!
Ray and the general concensus on bolt-on covers has been a resounding NO. -----Original Message----- From: No Quarter <[email protected]> To: vintagvw <[email protected]> Sent: Mon, Feb 2, 2015 2:32 pm Subject: Re: [vintagvw] Stock vs bolt on valve covers Kyle - this is one thing that we've discussed over the past 20 years on the list (and not recently mind you as the list is really, really slow compared to what it once was, but our quality has still remained thank goodness...) and the general concensus on bolt-on covers has been a resounding NO. If you get the good stock cork OEM gaskets and use the clip-on bail springs, you will have far less leaking - even to the point of NO leaks if you have no scratch marks on the faces for which the oil can trickle through. The air-cooled VW engine expands and contracts a substantial amount (remember why you need .006" valve clearance!) and so the spring bail does an excellent job keeping the proper tension on the valve cover throught the entire operating temperature range. I love getting my valve covers powder-coated black. The bail slides on them nicely and the powdercoat seals up any small scratches. You'll find the OEM gaskets (cork) do a great job of sticking themselves on, however if you need just a little sealant to help hold the cork gasket in place, a little Gaskasinch on the valve cover will help to ensure the gasket comes off with the cover once removed, and keeps the gasket from collapsing into the rocker area. It's a great question that you asked and I'm glad you brought it up. Now you know why you see plenty of bolt-on covers for sale at the swaps. It's because they either don't work as well or flat-out not at all. If you need to vent your valve covers, you can get the spiggots that fasten on with a threaded nut and gasket, but it's a good idea to just weld or braze them on to the stock valve covers. They won't leak around the vents this way and functionally are better than anything you can buy in my opinion.
