Customer Question

Ok so I have a 2003 Toyota Highlander with the 3.0 v-6 I replaced the timing belt once with no problems but got it back together and let it run to operating tempature and noticed the rear cam seal was leaking a good amount of oil so I tore it back down again fixed the cam seal, the second time I tried putting it back together I had a really hard time getting the tensioner on since it bolts from side unlike most other 3.0 1mz which bolt from bottom up anyway the cam on the rear went back on its own after applying pressure to install tensioner so now I have it back together the (engine itself) to see it run and make sure there is no issues but when I try to crank it, it is starting but missing really bad I don't know what I did is it possible the rear cam going back like that could damage something or could it be a revolution off the timing marks are spot on and not hearing and bad (metal) sounds have rotated engine by hand several times nothing sounds or seems unusual

good afternoon my name is ***** ***** I will assist

the motor is a free wheeling motor so if you did install the belt wrong you will not cause valve damage

check the plugs, wires and coil and be sure all your connections are good and in the correct position.

start there

Well i work 80 hours a week so haven't got to it yet but all the connections are good I wouldn't have asked for help if it were that simple lol I have to double check the timing alignment it either that or a cam position sensor have to check continuity ... You don't live in South Florida do you or know a mechanic that does willing to pay top dollar to complete this no time here
