Help timing a 2g

[thefeller1881]

Ive read about counting the belt teeth when timing my car. They say to count from the timing mark on exhaust cam gear to the intake cam gear and it should be 39 teeth. i dont understand am i suppose to rotate the gear until the marks are on the outside of the gears lined up like the pic i loaded up and if so i counted 40 so my car would be one tooth out so which gear do i correct? the reason for this question is because my car is lacking power after my belt broke had head rebuilt and new oil pump and pulley.

Put the engine at TDC, with the cam sprocket dowel pins located straight up. Then take another pic.

You're counting the teeth on the belt, not on the cam gears. Place the dowel pins in the 12:00 position. See the two timing marks on the inside portion on the cams? The exhaust cam is usually one tooth off, slightly above the intake sprocket. Notice on the outside of the cams there is identical markings. Mark the belt, count out 39 teeth and mark it. Place the first mark on the intake cam where the cam marking is. Zip tie the belt in place. Now run the belt over to the other side and place the 2d mark on the belt on the other cams marking. May have to use a wrench to rotate the camshaft slightly. Zip tie that one in place. Check the markings on the center of the cam shaft sprockets. They should be paralell to each other. If not, rotate one of the cams until they are. Shouldn't have to move more than 1/ 4 inch or so. You can now make sure the crank and oil pump sprocket are timed and feed the belt on.

new pic now what??

 

[g4ebguy90]

timing looks spot on.

 

[thefeller1881]

they are but i counted 40 teeth and everyone says there should only be 39 and now my car is lacking power so thats gotta be it cause before the belt broke nothing was wrong with it

Do a compression test. If you didn't bend some valves when the belt broke I'll nominate you for the DSM hall of fame.

Top marks look perfect. How about the bottom timing marks.

i had to have my head rebuilt and yeah i bent every valve but 4 i couldnt find the second timing mark on the intake cam gear the exhaust cam gear has two and so how do i count the teeth? i did a compression test and we are getting like 70-90 but i just had new weisco pistons, eagle rods and rings and the block bored .20 just about 4 months ago. the compression tester is like 15 years old could it be bad?

Could be a bad compression tester but generally when they go they won't read compression at all.

How many miles are on the motor and how did you break it in? Looks to me like the rings are shot.

 

[thefeller1881]

it might have 200 or 300 miles on it and i was told to take it easy on it for the first 100-200 miles except for the instructions i got to help seat the rings which was drive and get the rpms to about 4 or 5000 and then let it gradually idle back down normal idle but the car ran great until timing belt broke and i just got done using a a timing light and the gears were off so im gonna take it to a guys shop and let him set the timing and dyno it for me for like a 100.00. and now theres a squealing sound coming from around the crank so im gonna leave it be and let him mess with it cause i dont know squat about timing a car period except for lining up the cams and setting to TDC and timing the oil pump pulley. actually fine timing dont know and if something is off i wouldnt know besides the fact the car lost a lot of power.
