Anyone Have A Step By Step Valve Timing Guide?


Recommended Posts


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

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:



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


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.


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

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:
