pistonbroke Posted June 4, 2009 Share Posted June 4, 2009 I don't think the 2jz engine has intrusive valves anyway. So if the belt did snap, It would'nt damage the engine. Quote Link to comment Share on other sites More sharing options...

trinitom Posted June 6, 2009 Author Share Posted June 6, 2009 well some updates. Yesterday I have removed all the stuff to get access to timing belt and what i have found is quite impressing! 1st problem: the crank pulley bolt was so lose that can be turned by hand! and because of this the crank pulley have now a crack on the inner edge probably duo to vibration! 2nd problem: The timing belt tensioner bolt was over torqued by the previous owner or who have it changed , that the tread on the oil pump is completely fooked, this cause the tensioner bolt get lose and damaged the timing belt. (it nearly make a hole on the water pump casing!!) Now solutions for this: Get new or used good condition crank pulley. And About the oil pump I can get a new one, or mea by repair this one by welding the hole and make new tread, but honestly I’m more for a new one! And for the previous owner i must say this is a complete MONKEY JOB for who have changed the timing belt last time!! (without offending) pics: cleaned all the mess done by the belt. water pump nearly damaged by the belt Crank pulley crack and damage done by lose bolt! damaged tread on the oil pump that supports the tensioner.

pistonbroke Posted June 6, 2009 Share Posted June 6, 2009 I would try and get the oil pump re tapped mate. I believe it's a huge job to replace the pump, so I would try a cheaper re-tap first, especially if there is nothing wrong with the pump itself. With regard to the crank pulley, look at it like this, at least you found the pulley problem out before it decided to jump ship of its own accord at 5000rpm . It looks like the original crank pulley anyway so could do with being changed. Once it's all back together, you'll get a nice feeling of smugness, safe in the knowledge that your new shiney crank pulley is good for many many years to come Quote Link to comment Share on other sites More sharing options...
