Hi i am new at this and i hope u guys can help me.
i have a gs300 2jz ge engine and i just change timing belt myself, unfortunatelly timing set off while trying to lossen crank pulley bolt because of lack of decent tools. i set the timing back abnd install timing belt and everything back, turn engine on and the valves start ticking hard and car wasn idling even. drove the car for a while now it seem it idles nice but the ticking ts still there. do you guys think i could have demage something while setiing the time back or its just simple coincidence. the car seem its running normal thogh. adjusting valves might solve the problem?? please help
thanks in advance!!

I got to drive the car.the car runs strong. Windows up u dont hear anything. And yes i had to adjust timing on the crank with the belt off because when i try to losen the crankshaft pulley , the timing belt jump 2 teeth. I had no other choice. As a matter of fact the more i drive the car the less it sounds. I guess i keep driving until gives up. Good excuse to do a 2jz gte swap. I put some tranny fluid in the engine while that happens

Bent valves. Pull the head, take it to a machine shop and reinstall.
I'd find someone else to do the work. You only get one chance to get the timing right on the VVT motors.

If you adjust the cams by themselves without a belt on, it'll leave valves down, and when you move the crank, BAM, it'll slam right into the open valves. Like CleanSC said, find someone knowledgeable to work on it next time. Unless you have deep pockets, it isn't a good idea to do it yourself lol

no,
Better advice is to take a class or learn under proper supervision from someone who knows how to do it.
Most skilled trades are not independent study like pure education.
The industry still is in the older traditions of "apprenticeship" under the "master" mechanic, then you go out and do it yourself afterwards.
If you're learning by yourself, or even just trusting idiots, maybe you will pick up some skills, but in my opinion that is a fool's way compared to learning things properly.

^ I learned everything by myself well not entirely some DIY on here helped me out get started. I read up on how to do a 5spd swap, granted all the info wasn't there. Most of the time I improvise and it worked so far.
But a timing belt I would never touch I rather have someone who has done it before even if I have to pay a few bills it gives me the comfort of it being done correctly.

You only get one chance to get the timing right because if you start that engine out of time, you bend valves. Non vvti motors are safe, as they are non-interference engines. Vvti motors are interference engines, so you have to be absolutely sure the timing is spot-on before starting it. Verification is easy, just turn the motor by hand two full times and make sure the timing marks line up each time. Always do this with any timing belt work! If they don't line up, remove the belt and try again. Do not start the engine unless absolutely sure!
Removing and replacing a head is a whole other can of worms, I recommend the help of someone with experience in this area.
Good luck and report back with any findings!
