Guest Simon Bolton Posted July 9, 2007 Report Share Posted July 9, 2007 Hi all Nice easy one for you. What's the best way of sealing the cork rocker box gasket- Can't seem to get mine oil tight! Many thanks Simon Quote Link to post Share on other sites
Richard Crawley Posted July 9, 2007 Report Share Posted July 9, 2007 I use a light smear of Blue Hylomar to hold the gasket in position in the rocker cover recess & a light smear of grease on the cork to seal against the head; use a new fibre washer under each steel washer on the fixings. The trick with these is not to over tighten the rocker cover fixings; the more you tighten the more the cover distorts & the more it leaks; in some cases covers have been permanently distorted!

jonlar Posted July 9, 2007 Report Share Posted July 9, 2007 Hi Simon, can only second Richard's comment - don't do the securing nuts up to tight, unless a tubular space tube is on the stud under the cover, with a washer above - if just a nut and washer, use a Nyloc.

robgeev Posted July 9, 2007 Report Share Posted July 9, 2007 Use spray glue (carpet glue or similiar) to bond the gasket to the clean rockercover, let it dry for a bit, then fit, as mentoned, don't overdo the tightening, just nice even pressure across the 3 studs.

Guest ron Posted July 9, 2007 Report Share Posted July 9, 2007 Hi Simon Any proprietary seal will do or even none at all if the cover is good. The problem as already posted is usually caused by overtightening and a distorted cover, it is worth dressing it with a hammer and dolly to get the flanges flat and the bolt holes true. A nice alloy cover solves the problem 100% and if you just nip the gasket it is reusable about half a dozen times. Ron Quote Link to post Share on other sites

john.r.davies Posted July 11, 2007 Report Share Posted July 11, 2007 Simon, No amount or style of sealant will seal if the surfaces aren't straight. The standard rocker cover is a very light weight pressing, and distorts easily. Check it for twist, by placing it on a flat surface with the light behind - a table top in front of a window is fine. Is the edge flat on the table? And check that your DPO hasn't overtightened the hold-down nuts. The area around the studs can get depressed and this can lead to distortion. Carefully beat out any reverse bulges. And dings in the edge - again, careful beating out required. Good luck! John Quote Link to post Share on other sites
