how do you ensure tdc on cylinder one?

[canonize-ryda]

On my timing i never did the cylinder one part. Just lined them up. So how do i go about getting the cylinder part right? thanks

You can pull the #1 spark plug out and put a long screw driver down in it until it sits on the piston. When it stops moving upward, its at TDC.

I have a small metal rod that I sit down in cylinder one for testing purposes. You can see when you rotate the crank it will get to its highest point. I usually do about 10-15 rotations so I can get a feel for exactly when it starts to go back down. Best way to ensure TDC for Cylinder 1 in my experience.

thank you. I have it so number 4 is up.. I may have bent some valves here. Hope not

Number 4, and number 1 are both tdc at the same time, 2, and 3 are also the same.

I just now checked and yea i was on tdc one cylinder one. Do you have to time the balancer shaft?

 

[Boomdeeze]

If you still have the balance shafts in, you have to time the balance shaft sprocket too.

Would a out of balance shaft make it read Zero compression?

Nope, Have you performed a leak down test?
With the piston at TDC are the cam dowel pins pointing straight up with the notches in the gears at 3 and 9 o clock?

Yup with them line up perfectly on the cams. But when the cylinder is tdc my main pulley is maybe a half cm past the tdc on the timing cover.

Line the engine up with #1 TDC. this mean the crank pulley should line up on its corresponding mark. Which from what you are saying is that your cam timing is off. You always ensure the crank is lined up first, dont try lining it up by the cams.

Time to pull the head.

Yea it is...I hope i get this manual and i will be getting down to tearing it apart.
