    Hello,
    First off I would like to thank anyone in advance that can help with any advice. :]

    I purchased a 1993 4runner 5 speed, with blown headgaskets.

    I did not have alot of money so I decided to tackle it myself.

    I followed all removal steps, and took the heads to get rebuilt with cams aswell.

    When I recieved the heads the cams where removed, so I looked up in the manual and saw that when the crank is in TDC number #1 camlobes is facing up. So Installed it that way, I cant seem to match the time marker to the rear timing mark and have the cams facing straight up.

    Is there something im missing? How do the cams look when they are in TDC? ive looked at atleast 5 forums, read through the whole haynes manual, and watched alot of youtube videos. None tell me what the steps are to make sure everything is in TDC when cams are removed. Any advice will help.

    There is a right and left camshaft. They both have markings telling you which is right and left aswell as arrows showing correct position. You got me on the whole belt drive gear, can that be considered the crankshaft?

    I read a thread on timing, and i believe i may be over thinking it... Aslong as the marker is lined up on both R and L cams, and the crankshaft belt guide is at tdc. I can slip on the timing belt on, spin the engine 2 revolutions and if they all line up. Then im good to go?

    If everything lines up after two revolutions then yes you are good to go. Did you ever get it all figured out and put together?

    Appriciate the reply, this issue was resolved. I lined it all up, finished putting engine back together. And it started right up.
    Only issue i have now is that the thrrotle gets stuck somehow and rpms randomly go up and down.

    Yeah I've noticed a sticky throttle on mine too. Gets on my nerves. The rough idle is probably a bad idle air control valve
