You need to contact the cam manufacturer. Usually 32-40 BTDC @ 3000 rpm.
what is the timing marks on the camshaft what is the timing marks on the camshaft
Does the 1991 2.5 s10 have a timing chain or a belt or just mesh gears and how do you replace them The camshaft is gear driven off the crankshaft. The camshaft gear is pressed onto the camshaft. The camshaft must be removed from the engine to change the camshaft timing gear. The timing gears should last the life of the engine. Next time, please don't answer your question with another question.
It is the "Advertised duration", used by the factory. It is the Valve timing from when the valve is .006inches off the valve seat to .006" off the valve seat.
You can set the camshaft timing on your automobile by lining up the timing marks. There will be timing marks on the front main pulley and timing marks on the camshaft.
My timing belt slipped on my 1990 tyota 4runner 3.0. The crankshaft mark and camshaft marks do not align. Should i keep the crankshaft aligned and then align the camshaft marks?.
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.
your timing is out
The camshaft is turned by the timing chain or belt.
Camshaft Sensor is used to adjust the timing to to belt stretch
Both, cranshaft to camshaft sprocket, belt, camshaft sprocket to cams, chain.
There should be a hole in the camshaft that aligns with a hole in the head. That locks the camshaft to #1TDC. Then manually turn the crankshaft until the #1 piston is at TDC. Then install the head and timing chain.
Yes. The camshaft determines valve lift, duration and timing. By changing those specifications the engine performance can be significantly modified.
