Timing Belt Change Question

[TexasProton]

Taking the valve covers off to set timing is not needed. You state that when you are at the 9 o'clock sprung position and turn it 90 degrees more to the 12 o'clock, it sprung and stayed there.

Fen, I kept turning the LH Cam until it sprung back to 9 O'clock (Based on the Head O'clock concept). I then turned it 90 degrees to the 12 O'clock timing mark on the Head...It stayed at that position, it did not spring back to any position, and I did not have to hold it in place...it stayed there on its own!

I tried that procedure over the weekend with the Crankshaft sprocket in the BDC, which caused the backfiring

I tried the TDC position last night, I turned the Crankshaft two full turns, but the timing marks did not line up as they were supposed to had the timing been right

I did turn both Cams several turns passed the 12 & 9 O'clock...in other words, I did not take the first right position.

I'll try it both ways again tomorrow night, but this time, I will do at least 9 Cam revolutions per Cam to see if I an hit that magical spot on the LH Cam.

Thanks again for your reply.

Update...

1- I turned the Crankshaft sprocket so the Timing hash mark was at 3 O'clock (BDC) and aligned it with the timing hash mark on the oil pump cover

2- I turned the RH Cam (passenger side) at least 9 full turns (I watched the timing mark on the Cam pass by at least 9 times). I then rotated it again until it sprung back to 12 O'clock (using Head O'clock reference)

3- I did the same thing with the LH Cam (Driver Side), but let the Cam spring back to 9 O'clock (Head O'clock reference)
4- I turned the LH Cam an additional 90 degrees until the timing hash mark on the Cam was aligned with the timing hash mark on the Head
5- I aligned the marks on the belt with those on the pulleys and made sure nothing moved
6-I installed the tensioner and released the pin
7- I turned the Crankshaft sprocket TWO full turns...Nothing lined up...not even close

8- I repeated the same process, but this time I started the Crankshaft sprocket in the TDC position (Halfmoon cutout notch at 3 O'clock)
9- I turned the Crankshaft sprocket TWO full turns...Nothing lined up...Not even close

Note: The timing marks seem to get aligned every 1.5 Crankshaft turns
