If it has a keyway in it, it can oonly go on, one way. Front & back only make a difference, if the timing mark isn't on both sides.

Ok 1990 geo storm 1,6 litre dohc replaced water pump replaced 3 valves replaced head gaskets replaced timing belt car wont start any ideas?


90 Storm, must be in Canada, 1,6 (the comma tells me this)
the storm is a:
The car is really an Isuzu Impulse minus some of that car's more expensive features.
my guess is you drove the this 4EX1 engine until the cam belt slipped. yes> if yes you bent valves.????????????
so does compression exceed 150psi on all 4 cylinders now?
we use the cylinder leak down test in all DOHC .
if not , back to the drawing board.
if yes, the we check spark next, then try test fuel.
when did the engine last run , last week,month , year,?
who did your valves, a real machine shop or kid down the street.
a read shop pressure tests the head ,and warp checks it and
then makes sure the valves are ready for long service.
are the head bolts at 58 ft/lbs
did you use sealant on the 3 cap caps, per the FSM book.
if not , top end oiling will fail. and cams wrecked.

the 1.6l DOHC has no HLA's
the lash on valves must be checked, and this is corrected with SHIMS.

a pro machine shop does the for you,did they:?
when rebuilding engines, its best to read the factory service manual first. FSM so you know the special steps just for this engine.
ISUZU engine it is.



quote.
1.6L Twin Camshaft Engine
  1. Disconnect the negative battery cable.
  2. Remove the cylinder head or valve cover.
  3. Position the No. 1 cylinder at TDC on its compression stroke.
The notch on the crankshaft pulley should align with the 0 degrees mark on the timing gear case. Make sure the rocker arms on the No. 1 cylinder are loose and the rockers on the No. 4 cylinder are tight. If not, turn the crankshaft one complete revolution and align the marks again.
  1. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 1 cylinder, then the intake valves on the No. 2 cylinder and the exhaust valves on the No. 3 cylinder. Note readings.
  2. Rotate the crankshaft 360 degrees. Using a feeler gauge, measure the clearance between the cam lobe and the selective shim on the intake and exhaust valves on the No. 4 cylinder, then the intake valves on the No. 3 cylinder and the exhaust valves on the No. 2 cylinder. Note readings.
  3. The valve clearance obtained on the exhaust valves should be between 0.008-0.012 in. (0.20-0.30mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 (valve lash spring spacer) between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.
The rear camshaft bearing caps must be removed to remove the selective shim.
  1. The valve clearance obtained on the intake valves should be between 0.004-0.008 in. (0.10-0.20mm). If not, replace the selective shim by turning the camshaft lobe downward and installing tool J-38413-2 or J-38413-3 between the camshaft journal and the cam lobe next to the selective shim. Turn cam lobe upward and remove the selective shim. Install new shim using the selective shim chart.
  2. When the adjustment is completed, install the cylinder head covers and connect the battery negative cable. Start the engine and check for leaks.
end fsm quote.

see those 2 marks, and crank must be at TDC. mark first.

Finding out how to find lost cam timing mark on a 1997 volvo 960


you are in a bit of a bind. Turning the engine over will result in bent valves so do not touch the crank shaft. you have to loose off all the rockers/ cam followers even to the point of removing the cam shaft. having done that remove no1 cylinder spark plug and by the use of a thin piece of wire turn the crank until the piston reaches top dead center. find this by rocking the crank back and forward until the piston dose'n move up or down check for the crank timing mark next replace the cam shaft and position the cam lobes for no1 piston in such a position that the inlet and exhaust valves move slightly up or down when the cam is moved slightly left or right. this is called valve over lap and with the piston on top dead center means that you now have valve timing for the engine. Cam timing marks can be dot on gear to shiny link on chain or if using a belt a dot on tooth lineing up with mould mark or join on head before starting up do a compression check to prove that there are no bent valves. if you are not mechanically minded enough to attempt the valve timing method it may be cheaper in the long term to let a qualified person do the job

How to replace a broken timing belt for a 1998 daewoo lanos?? Would there be any head damage?


yes it is quite possible that valves are bent if the cam belt broke or teeth stripped off of old belt, which unfortuneately means removing the cylinder head and getting it repaired (valves replaced and possibly guides) see some of my other posts for cam belt timming marks locations etc...
depending what motor is in your vehicle twin cam or single?

stevenhurc_14.jpg and if its twin cam you usually need cam locking tool for cam gears.

2001 HYUNDAI SANTE FE 2.7 V-6 NO START- SOUNDS LIKE NO COMPRESSION( SPINS WAY TO EASY) CHECKED COMPRESSION ON FRONT CYLINDERS 0 PS1 FRT 25 PSI MIDDLE 50 PSI REAR ASSUMED OUT OF TIME-PULLED FRONT...


Yea, because what probaly happened is that, you dropped a cylinder or two...which means you probaly have bent valves..that's why your compression is way out of wack...I believe that engine is an interference engine..so when the timing became off, the piston hit the valves..and bent them...You can take the heads off and have a machine shop, or you, can put new valves in it...Good Luck

If it made it to any valve, it may have bent the valve shaft but it is more likely that a rod bearing is announcing its retirement.
A bent valve shaft would put that cylinder out of business and you would have a pronounced miss.

IF YOUR TIMING BELT BROKE OFF BEFORE YOU CHANGED THE TIMING BELT DO YOU HAVE TO TAKE THE COVER OFF OF THE HEAD VALVE LOOK AT THE CAMS AND YOU WILL SEE THAT THE VALVES ARE BENT IF THE CAM IS NOT TOUCHING THE VALVES ARE BENT BEFORE YOU ALINE THE CAM GEARS YOU HAVE TO PUT THE CRANK SHAFT GEAR IT HAS A MARK AT THE BOTTOM OF THE OIL PEN MAKE SURE THAT WHEN YOU GET IT ALL SET UP RETURN THE GEAR TO THE MARK ON PULLY ALSO THE TIMING MARKS ON THE CAMS HAS TO MARKS ON THE COVER THE LEFT CAM GOES AT 12:00 THE RIGHT CAM MAKE SURE THE EXHAUST LINE LINES UP AT 12:00 OTHERWISE IT WONT START BECAUSE YOU DONT HAVE NO COMPRESSION I HOPE THIS IS HELPFUL FOR ANYBODY THAT NEEDS TO REPAIR THE ENGINE
