Technically that could be possible with a DOHC 4-cylinder and a timing belt driving two pulleys (one for each cam), although the 4g63t Mitsu engines Im use to running just bend all 16 valves on the pistons, without any VVT. On this 1ME, the exhaust cam being driven by one drive pully and connected with helical gears to drive the intake cam, it might be possible on one cylinder to have the helical gears timed wrong while going back together, but thats a long shot. Having hydraulic roller lifters should eliminate the chance of float if everything is in correct working order.

its in the under the cargo area, left side.

Are you saying the valves could hit each other?? If so, how in the world would that be physically possible?? I was hoping to do this all today, but my re-ring/re-seal kit still hasnt made it here from Utah after 10 days, and the machine shop still isnt done with the heads after 14 days What ever happend to good customer service????

I know, Ive done this a few times before ;) I just joined this site for the links to service manuals (my trans went out at 226k, so Im re-ringing the engine while its out), but it seems Ive gotten myself into more than just looking up .pdf's now.

Looks like I joined this site just in time then. Once I pick my heads up from the machine shop tomorrow, Ill measure the valve opening distance to compare to TDC. And yes, Ill even post pics. Ill put money down that its a non-interference, anyone want to bet against me?

link to previous debates on here? Im sure the ES guys are in on this as well

Ive seen several 1mz-fe (with vvt-i) timing belts break and never wipe out the valves. Do you have proof of prior statement?

There was a recall on some RX330 brake boosters, maybe it could be part of that..

I replaced the belt on my '99 for the first time at 180k, and it still looked clean and solid. The valves arent an interference fit with the pistons, so even if the belt does break it wont do any damage to the motor...you'd just have to get a tow truck.
