Hello,


99 sonata v6 2.5
I do have a problem.... Being that my cams are directly opposite of TDC
and my Timing mark on the crank is directly opposite of the TDC mark as
well.... HOW do I get the timing alingned?

How do I know when the crank is at TDC? Even if it is at the mark, it
could still be wrong (not at TDC..) Should I take the plug out of # 1 to
see when the cylinder comes to the top? I am lost now (doesn't the crank
make 2 revolutions per each cam gear?).....

I feel sick over this now!!!


THANKS FOR ANY HELP!
 
Ok, I'm thinking of this now...

TDC on the crankshaft is TDC on cylinder 1 ALL the time the mark on the
shaft is in line with the TDC mark on the engine right? (the shaft is 1
piece that for every revolution pushes the #1 cylinder to the top when it
is on the TDC timing mark- on the CRANKSHAFT).

The dillema is the CAMSHAFT gears that I have to line the Timing marks on
once the CRANKSHAFT is at TDC timing... What can I do?

Thanks
 
When #1 Cylinder is at TDC, shouldn't the intake valve(s) be wide open,
and the exhaust valve(s) closed? Or I guess maybe that should be the
other way around. Just a thought.
 
Just line up the timing marks on all the sprockets to the marks on the
heads/block.
 
There is no timing belt on now....Don't I have to turn the CRANKSHAFT back
(counter clockwise) a couple teeth, and then move the CAMSHAFT clockwise
the same amount of teeth? Or can I move any of them freely without
worring about hitting the valves to the cylinder while lining up the marks
(it is pretty far out now.. the cam timing marks are on the opposite side
of the cam gear now, and the crank mark is on the opposite side of that
gear as well.)

sounds like you do it by feel. move the crank some, if it binds then
rotate the cams to clear the offending valves. repeat unitl they are
all lined up.
 
Do make sure you don't put undue force on anything. It should be easy to
tell if something bad is happening. It'll get nearly impossible to turn
very quickly.

At TDC, both valves should be closed. TDC is the point where the highest
compression would take place if the cylinder did not fire. Firing
usually occurs a few degrees Before TDC (BTDC).
