Busybee Posted June 23, 2002 Share Posted June 23, 2002 I have a 1993 ES300. Is there a set mileage at which I should have the valves adjusted? My dealer is pushing me to do it even though the car sounds and runs fine. Quote Link to comment Share on other sites More sharing options...
AWJ Posted August 1, 2002 Share Posted August 1, 2002 You can usually hear them clicking over time. Some cars recommend 60,000 miles others 80,000. I do mine when I notice them clicking a little more than usual. It is good to adjust the lash. It is possible to go 100,000 miles but I would do it then at least. It is good to have everthing nice and flush in the valvetrain. Quote Link to comment Share on other sites More sharing options...
voeltz Posted September 29, 2002 Share Posted September 29, 2002 how do you adjust them? Quote Link to comment Share on other sites More sharing options...
AWJ Posted October 4, 2002 Share Posted October 4, 2002 I personally have not done a valve lash job. It takes some special service tools to be done correctly as well as a selection of shims that need to be inserted. It is really pretty tight work and takes a little bit of skill. It is not impossible, but I have not tried yet. I Usually take it to a trusted mechanic for that one. Quote Link to comment Share on other sites More sharing options...
zeta Posted January 19, 2003 Share Posted January 19, 2003 hey AWJ, what do you mean by valve lash? the VC's? or what? :? Quote Link to comment Share on other sites More sharing options...
AWJ Posted January 19, 2003 Share Posted January 19, 2003 The clearance between the valve stem and the camshaft lobes. This increases due to wear over time and as a result needs periodic adjustment. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 11, 2003 Share Posted May 11, 2003 funny lexus goes for perfection with so many things but not with self adjusting valves like most cars today or timing belts that actually last like the new vdubs with a kevlar belt ( same stuff they make bullet proof vests from) Quote Link to comment Share on other sites More sharing options...
