should be in between intakevalve movement and exhaustvalve movement
Yes, valves should be closed.
#1 piston should be at TDC and both valves closed (compression stroke)
If the timing is retarded due to cam and crank timing, the answer is YES. If it is due to distributor or ignition timing NO. Compression is produced mechanically when all the valves are closed during the compression stroke of the piston. If all is well (rings and valves), you should achieve optimal compression from the engine. Almost all gasoline engines require a least 80 psi to fire the cylinder.
Well if you lined up the timing marks properly then it would not matter. The engine would run anyway.
Neither, on a 4 cycle engine the timing is set at the end of the compression stroke of the number 1 cylinder.
To determine if the number one cylinder is on the compression stroke after the timing belt has snapped, first, turn the crankshaft manually to align the timing marks on the crankshaft and camshaft. Next, remove the spark plug from the number one cylinder and place your finger over the spark plug hole; you should feel air being pushed out as the piston moves up, indicating it's on the compression stroke. Additionally, you can observe the position of the piston through the spark plug hole; it should be near the top of its travel when on the compression stroke.
The timing gears basically first the cylinders in the right sequence and when the compression is at it most optimum
Timing marks for twin cam 1.6L B6 engine. When crank pulley is at TDC on the compression stroke, 'E' & 'I' on the camshaft pulleys should be at 12 o'clock. Too easy.
When installing a distributor in a motor, the rotor button should point to the terminal of the ignition wire for the number one cylinder at top dead center (TDC) on the compression stroke. This ensures that the ignition timing is correct when the distributor fires. It's essential to confirm that the engine is at TDC on the compression stroke, not the exhaust stroke, for accurate timing. Proper alignment ensures optimal engine performance.
get the #1 up on compression stroke crank gear mark at 12 & cam gear at 6 this should work
Look for detent marking on camshaft sprockets and align them with timing marks on cylinder head, should be visable markings and ensure that engine is at TDC on compression stroke, and timing marks should all line up
Yes, if #1 is at TDC on the compression stroke.
More than likely your timing belt is not installed correctly so you have open valves when they should be closed to have compression...
