No 1 piston tdc
the cam lobes for no 1 piston should in such a position so that a slight turn of the cam shaft one way makes the exhaust start to close and the inlet start to open or the other way the inlet start to close and the exhaust start to open
this is known as valve rock or valve overlap and occurs when the cam shaft is properly timed to the tdc position of the piston
for a twin cam engine the cam lobes position will be the same operation just that the inlet cam rock will be for the inlet cam and the exhaust cam rock will be for the exhaust cam

SOURCE: Looking for cambelt timing marks/ positions please, Twin cam engine Thanks Kevin

these bend valves if belt breaks while running
Align the timing marks on the camshaft gears to the notches on the camshaft cover, using the intake gear mark for the intake gear and the exhaust gear mark for the exhaust gear.
Align the mark on the crankshaft gear with the
notch at the bottom of the rear timing belt cover.

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.

How to disquinguish the intake cam from the exhaust cam,,mine got mixed up while doing a headgasket job .


the cam shaft may be identifiable but I doubt it as the lobes will be all the same .It may take a trial fitting of the cam shaft to determine which is which. Place the no 1 piston on TDC and install the cam in the exhaust side of the head. position a the no 1 piston cam lobe in the just closing position. Check where the timing mark will be in this position ( the engine make and sized would have been an enormous help here as the key position or timing mark on the gear would have revealed what cam it was). Place the other cam in the position where the no1 cam lobe is just opening.. This is called valve overlap and from the positioning of the timing marks will show if the cams should be interchanged . The marks will either both face down, face each other or face upwards. If they face out wards away from each other then interchange the the cams and if that makes the marks face each other then it may be right. Another way ( probably simpler will be to put a cam in place and the cam lobes will be directly in line with the rockers over the valves or directly over the valves. Workshop manuals are a big help when doing this work.

While replacing timing belt on my 2003 pt cruiser (2.4 liter) I got the belt on with the crank pulley and compression pulley (top front) in timing but exhaust pulley (top rear) off by one tooth. Took belt...


To readjust the cam timing loosen of the valve rockers so that the valves will not move as the cams are turned.. Set the crankshaft on TDC no 1 piston. This will make the mark on the crank sprocket line up with a mark on the housing. The cam shaft marks are to ne facing each other with the "up" marks facing up. Loosen of the adjuster idler and use an allen key to lever the pulley away from the belt. Fit belt and let tensioner off Ensure tensioner spring is in line with the notch. Repeat procedure to get it there.. The valves will now be timed . replace the rockers and adjust as required . The problem that you had is that there was load on the cam lobes from incorrect positioning of the cam shafts and the shaft turns until the load was equal between two lobes.. There is every possibility that there will be bent valves as it is an interference motor.

"I tore down my 2005 Hyundai Santa Fe 3.5 engine and my son decided to clean the garage. In doing so, the camshafts were placed in a box in no order. There are several numbers on each camshafts. Also,...


looking from the water pump end the side on the fire wall will be the LHS. You can distinguish which cam is which by placing the cam in position and seeing if the cam lobe is over a valve. If the lobe is over an inlet valve (inlet manifold hole then it will control the inlet valves an so on for the exhaust cam. Before you place the cams in position make sure that you have the no 1 piston on top dead centre with the timing marks positioned correctly and do not touch the crankshaft again as the timing will all be done by the positioning of the cam shafts.

The cam gear has a triangle and a diamond , which mark do you line up to mark on back cover ?


Not sure, but you should be able to figure it out by how the valves set. At TDC of number one cylinder on the compression stroke, the valves should be fully closed and the cam lobes for #1 will be more or less in an upward position. If this is a Nissan, I think you want the "diamond" up, but just not positive about that.
If you want to play with it and try in both positions, first turn the crankshaft back a few degrees, so no piston is at the top of block. That way, no chance of valve kissing a piston crown, the kiss of death for interference engines. On a running engine with wrong timing, that is how valves get bent or broken.

I found crankshaft mark but not cam there is two marks on the pulley that don't seem to line up with anything, can someone please help. Thanks


There should be a mark on the camshaft .If not you are going to have to remove the valve cover,and set the camshaft at its top dead center and recheck the for cam marks and you will find out its there.On the number one cylinder valves,is what you are going to be of concern, on the camshaft there is what you call lobes,On the lobe are what you call a heel and a toe,(the big part of the lobe is the heel and the small part is the toes),The toes should be out board of each other.recheck for cam marks at this time

Hi where are the timeing marks on a 1.6 16v astra


nice set of wheels ,cant remember since i done the last one?? right it either has locating lugs on the cam between the cam lobes on no1 ,or horizontal slots on back of cams ,or is that an escort ?' or 8mm hole in cam wheel that locks into the head with a drill bit or an bolt?' or was that VW .If not sure then both inlet and exhaust valves are closed and the valves on no4 open with cams on teh rock so to speak ,then look for the timing marks and next time bring engine to no1 and mark it with white paint

Need timing marks for 2002 ford explorer 4.0 engine. trying 2 check timing chain. any one know specs


There are no marks on this one. There is a special tool set to align camshafts ($900). The best you can do is to bring #1 cyl to TDC compression with both cam(valve) covers off. #5 cyl should have lobes at equal opening, exhaust just closing and intake just opening.. #1 cyl cam lobes should each be diametrically opposed to the positions of #5. If cams need to be moved, there is no registration of gear onto cam. Just loosen bolt holding gear and move cam. Retighten bolt. Roll thru 2 crank revolutions and check cam timing again.Simple.
