Hey guys, new to the forum, thanks for the opportunity to be a part of it.

 

I just did my timing belt, first surpirse was the fact that there was no timing mark for the crank, the sprocket on the crank had a dimple, but there was nothing to match it up to, so I made a mark just in case.

 

Before I took the belt off ,I also put the cam sprockets to the marks on the rear cover. So, with this i took the belt off, as I was putting on the new one, the passenger side sprocket got out of place, I rotated it the same way the engine would back to position.

 

Put everything back, started it up, absolutly NO POWER! It is obvious the timing is way off.

 

I just tore every thing down again, Lined up all the marks again, made sure the #1 piston was at TDC with all the marks lined up and it is.

 

Any input, any help, please!

 

 

Thanks in advance,

 

Paul

Well the #1 is at TDC and the cam sprocket above that piston has its dimple lined up with the dimple on the back cover so I am under the impression that is compression.

 

 

 

 

 

 

 

you at TDC on the compression or exhaust stroke?

Problem solved, counted the teeth, BUT, there is an odd whine coming from the timing belt area........

 

Did you replace the water pump too? I replaced mine when I did my TB and it made a funny whine even when spinning it by hand. It has gotten louder now (15,000 miles later) and I think I got a crummy one. :thumbsdown:

 

Also mine made a disturbing whine which was because the TB was a little too tight.

 

Sounds like you're gonna get real good at tearing the front of the motor off. :headwall:

If the belt is tight enough to make a loud whine, there's a risk of it snapping off the passenger side cam sprocket. There should be about 1/2" of deflection up and down in the belt, or you should be able to twist the belt 90 degrees.
