ADD Posted December 8, 2007 Share Posted December 8, 2007 i was changing my coil pack connectors today and noticed whilst the cam cover was off that the belt had moved about 2 or 3mm towards the engine but carried on with the task ahead. i started the car up to make sure all was running properly and i heard a squeeking noise coming from the cam belt area. took the car out for a spin (gave it a good booting) and noticed on my return that there was blue ish smoke coming out from the cam cover where the belt is......now i know i should be worried about this but how worried??? any help would be much appreciated.

ADD it sounds like the belt is rubbing on something inside the cover DONT DRIVE IT OR START IT TILL YOU GET THE COVER OFF FOR A LOOK you dont want the timingbelt breaking!(bye bye engine) it sounds like you havent put the cover on correctly and its catching the t-belt whip the top cover off and take a look at the belt alex:) Quote Link to comment Share on other sites More sharing options...
Homer Posted December 8, 2007 Share Posted December 8, 2007 DONT DRIVE IT OR START IT TILL YOU GET THE COVER OFF FOR A LOOK you dont want the timingbelt breaking!(bye bye engine) Thats incorrect. A snapped belt on any 2JZ aside from the VVTI NA should not result in engine failure. Every engine apart from that specific US only model is non-interference.

carl0s Posted December 8, 2007 Share Posted December 8, 2007 Every engine apart from that specific US only model is non-interference. and UK Spec mk2 Lexus GS300 by the looks of it. That's where all those VVTi N/As went to.. Quote Link to comment Share on other sites More sharing options...
ADD Posted December 11, 2007 Author Share Posted December 11, 2007 right this noise only happens when the car is cold, whenis warms up it goes? could it be as simple as the fan belt? Quote Link to comment Share on other sites More sharing options...
