How do you timing the valves without timing mark on the gear crank shaft and cam shaft?

Hmmm, you're asking the question about several different vehicles all with different combinations of cam/crank. The general purpose answer is, the factory gears all have marks on them (unless, for some crazy reason, someone has ground them off). If you've replaced them with something from the aftermarket, you should contact the maker/supplier of the gear (hard to imagine no marks though). For the Solara (this forum) to set cam timing without marks you'd have to be absolutely certain #1 cylinder was at TDC. You'd set the cam to have both valves closed (but you could easily be off by a tooth). You'd do the same with the crank turned precisely 180 degrees and, after determining which cylinder is now at TDC set that cam so both valves are closed. It would be a frustrating exercise that you'd probably have to do more than once. For the Fords with overhead valves it's a little simpler, just do the first cam procedure (you can still be off by several degrees so a cam timing wheel would be really handy). Frankly, I'd just get a new set of chain drive gears from Toyota or Ford and have done with it. Cheers

How does a timing belt work?
A timing belt is driven by the crank shaft and allows the camshaft to turn,which opens and closes intake and exhaust valves in their proper timing sequence.
Which component controls the opening and closing of the valves in an engine?
A cam shaft generally open and closes the valves. This is a driven component by a belt or chain to the crank shaft.
Where do you set crank and cam shaft marks to set timing on a 1996 Nissan Pathfinder?
Where do you set crank and cam shaft marks to set timing on a 1996 Nissan Pathfinder?" Did the timing belt snap ? if so the engine will have bent valves and require more work than just the belt. This is timing belt job is not one for the inexperienced diy mechanic. Not trying to be a wise guy, but get the manual, the timing mark set up isn't a simple explanation .
Replaced timing belt and all idlers and tensioner now has a miss and rough idle car was fine before this Whats up?
Chances are the Timing gears or pulleys are not properly aligned. The Cam shaft and the Crank shaft must be aligned properly so that the valves and pistons are "in sync"
Need to no were timing mark is on crank pulley on 1999 daewoo nubira?
Check the crank shaft pulley
Where is the crank shaft bearing located?
It's behind the timing belt cover on top of the crank pulley.
How do you replace the crank shaft sensor in an infiniti G35?
It is on the front of the crank shaft and under the timing belt cover. You have to remove the crank pulley and all the belts and then the lower timing cover. It is not a job for a beginner.from : http://repairpal.com/crankshaft-sensor-569
What is the pulley for your timing belt directly behind the crank shaft called on a 1997 Dodge Intrepid 3.5L V6?
Timing belt crank sprocket

Will a crank shaft seal fail without some type of warning?
YES ON ANY VECHICLE THE CRANK SHAFT SEAL CAN FAIL WITHOUT WARNING.
Where is the crank shaft position sensor located on a 2000 Mitsubishi Eclipse?
behind the crank shaft pully and the timing cover and then another pully is there two bolt hold it on
Does it ruin engine when timing belt breaks?
How can you tell it's an interference engine or If it's a non-interference engine, or if your valves are in the right place when the belt snaps? Also how can I remove the crank shaft pully?
