dave94ls Posted April 18, 2005 Share Posted April 18, 2005 Hi Im a brand new member here and I have to say that this is the most useful forum I have seen in a long time. Here is my question Im taking on the task of valve clearance adjustment. I would like to know if anyone out there knows of a good walk through for this. Any help would be greatly appreciated Dave Quote Link to comment Share on other sites More sharing options...
monarch Posted April 18, 2005 Share Posted April 18, 2005 A couple of us are working on tutorials, but they aren't ready yet. Read this thread thoroughly for tips and links to an Australian tutorial: http://us.lexusownersclub.com/forums/index...19119&hl=valve+ +clearance The toughest part of the job may be figuring out how to remove the valve clearance adjusting shims http://www.saber.net/~monarch/valveshim.JPG A factory toolkit specifically made for the 1990 -97 LS400 V8 is Toyota Part # 09248-55020, but it's currently on backorder at OTC tools and sells for a hefty $99. A near equivalent toolkit is the generic Toyota valve adjusting toolkit Part #09248-55010 which is this one on ebay http://cgi.ebay.com/ebaymotors/ws/eBayISAP...m&rd=1&item=249 2451948&category=43998&sspagename=WD1V The valve lifter depressing tool of the cheaper generic kit doesn't work very well on the Lexus V8 - it doesn't depress the valve lifter enough, but an effective work around is to depress the valve lifter using a large screwdriver that has been covered with 7 layers of tape to prevent any chance of nickingor gouging of the metal of the valve lifter. http://www.saber.net/~monarch/valvedepress.JPG Both tool sets include a valve lifter hold down tool that keeps the valve lifter depressed while you remove and install the shim with a magnet. It works well so you should buy the cheaper generic kit http://cgi.ebay.com/ebaymotors/ws/eBayISAP...m&rd=1&item=249 2451948&category=43998&sspagename=WD1V to get this important tool http://www.saber.net/~monarch/valveshimrem.jpg However, the installed shim is held tightly to the valve lifter by a film of motor oil. So before a magnet will even be capable of removing the shim, the shim must be loosened (dislodged) from the valve lifter using compressed air in this manner: http://www.saber.net/~monarch/valveduster.JPG Quote Link to comment Share on other sites More sharing options...
