Where are the timing marks on a DOHC engine?
A piston stop can be used to find the actual TDC position for the piston in the cylinder when the head (s) are on the engine. Most engines will have timing marks on both cam sprockets. On the RB26DETT engine, the dot on the cam sprocket lines up to a dash mark on the back cover. There is also a timing mark for the balancer.
How can I Find my TDC without a timing tab?
When you feel pressure against your finger, the piston is coming up on the compression stroke. Insert a plastic straw about two inches into the spark plug hole. Don’t let go of the straw. Continue to slowly rotate the crankshaft clockwise. You will feel the top of the piston hit the straw and push it up.
Where does the crankshaft go when setting to TDC?
So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
When to set the engine to TDC on the exhaust stroke?
NOTE When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.

When to set engine to top dead center ( TDC )?
Procedure NOTE When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
Do You need Timing pin for Zetec engine?
After fussing with the timing belt on a Zetec engine, I bought this and it made the job much easier. The pin wouldn’t fit in with the exhaust in the way, but gently bending the heat shield a bit allowed for it to slip into place without removing the entire exhaust. The pin fits great and was a must have for the job. 5.0 out of 5 stars Don’t guess!
