What happens if the camshaft timing is off?
What happens if the camshaft timing is off?
If the engine timing of the cam is off, your car will either be running rough or not at all. If the ignition timing is the problem, it isn’t as easy to notice because it has four cycles: Intake valve sucks in air while fuel is delivered by the injectors. The fuel mixture is reduced.
What should the timing marks be on a camshaft?
Count how many notches it is off and when you repeat, make the allowances by turning the camshaft the forward or backwards the required notches. The new timing belt should have markings for the various marks, using them would be the fastest and most accurate.
When does a cam line up with the crankshaft?
When a cam is installed “straight-up,” the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
What are the timing marks on a Camry?
Ok The best way I can describe it is after I get the timing belt installed, the tension set, then turn the crank the 2 revolutions clockwise the camshaft timing mark does not line up again, it is about a 1/4″ from making the full revolution and lining back up. This is a 1999 camry with 2.2I4.
Where are the timing marks on a 5S FE engine?
Checked tags and is definitely the 5s-fe engine. It has one gear bolted to inlet cam driven by the timing belt. Inlet cam has a second gear on it that meshes with a gear on the exhaust cam. Will find a picture to show what I mean. PS. I did originally mark the cams myself on the out side of sprocket, but these marks came of in the parts washer.

Where are the timing marks on the crankshaft?
The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head. With the distributor cap removed, the rotor should be pointing toward the No. 1 mark on the rim of the distributor housing.
Where are the timing marks on a VW?
Make sure that the camshaft and crankshaft timing marks are aligned. Install the timing belt, with the arrow pointing in the direction of rotation, on the crankshaft sprocket, the water pump sprocket and the camshaft sprocket. Install the lower and center timing belt covers.
Where are the timing marks on a 8 valve engine?
On 8 valve engines, the notch on the crankshaft pulley should align with the dot on the intermediate shaft sprocket. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the sprockets. Check the alignment of the timing marks.
