Engine Cold Start Rattle

Hi all,

I suspect I know what I need to do, but anyway: on cold starting I SOMETIMES get a loudish rattle from the engine for a half second or so. I suspect hydraulic tappets or maybe a chain tensioner - any comments or ideas??

I probably need to visit the dealer - however intermittent faults usually never happen when a mechanic is near!!

best wishes

Always useful to try the search facility on the forum. The rattle on start up from cold is a problem known by Lexus and there's a TSIB for it (Technical Service Information Bulletin) discussed many times in this forum, and here's a link to one http://www.lexusowne...showtopic=54369

Ahhhhh thanks for that - looks like i'm in good company on this topic :shifty: my car's extended warranty runs out this summer so i'd better ask the question about its history in case it was looked at before for this fault.

cheers
