The Duel Overhead Cam (DOHC) design typically uses timing belts or timing chains to synchronize the engine's camshafts with the crankshaft. Whether a specific DOHC engine uses a timing chain or a belt can vary by manufacturer and engine model. It's essential to consult the engine specifications or service manual for the particular engine in question to determine which type it employs.
If your asking this question than you shouldn't be performing this job yourself<

To set the timing on a Kawasaki 750 LTD with dual overhead cams, first ensure the engine is at top dead center (TDC) on the compression stroke of the first cylinder. Align the timing marks on the cam sprockets with the marks on the cylinder head, ensuring the cam lobes are oriented correctly. Adjust the positioning of the cam chain or tensioner as needed to achieve proper alignment. Finally, double-check the timing before reassembling the engine to ensure optimal performance.
SOHC: Single overhead cam DOHC: duel overhead cam it just means if you car is a single can, or twin cam, the SL1 modles are single cam, and the SL2 are duel cam
do u set the timing marks at btdc or tdc on a 2.5 mercury cougar
To adjust the timing take off the timing cover,take off belt and then line up the marks on the timing gear.You will need a special tool to hold the gears if it is a DOHC(duel over head cam)
Single overhead cam have interference with pistons & valves. While in duel overhead cam engines there is interference betwen the pistons & valves & also between the intake & exhaust valves.
It will fit seeing that they are both 1.9 liter motors, however there would need to be several adjustments made since the SL1 has a single overhead cam and the homecomming has a duel overhead cam
ABSOLUTELY!
I'm pretty sure the 1.9 is compatible throughout in all the years as long as you get weather is is a single overhead cam or a duel overhead cam motor. This can be identified by the 7 or the 9 on the eighth digit of the VIN. A junkyard or a rebuilder such as jasper engines could tell you.
The homophone for duel is dual.
In real life you don't need a duel disk to duel.
