Finding the timing marks is simple, it is an impression (a small arrow) on both the crank and the cam. As for the exact time set, I would refer to the owner's manual but if you are doing it off the cuff pull the number one piston top dead center, line up the rotor button with the number one piston and set crank at top dead center and cam at bottom dead center. This will be a good starting point, but the owner's manual will give you more exact instructions.

    If you look at the front of the cam you will see an impression, it should be an arrow pressed into the metal pointing straight down at 6 o'clock - and that should be bottom dead center. It may be a little hard to see, but it is there. Be sure that you have the timing cover off.

I m looking for chain timing marks on xc 1.4 holden combo any one can help please

there is no marks on both camshaft gears or chain, and special tools are required if this is the twin cam engine with chain drive not belt.
timing mark on crank pulley must line up with mark on cover then there is a special tool that lock both camshafts at rear in the flat slots as well as lock pin to put into hole in block that locks cranck shaft.
then there is another special tool for camshaft sensor interuptor ring which is on one of the camshaft gears.

Where are the timing marks on a 2001 Oldsmobile Alero?

Need to Know what SIZE Engine to give this Internal Technical Info to you. Externaly The Crank Sensor picks it up from Harmonic Ballancer and so there are NO EXTERNAL Marks Nor Does the Manufacturer Provide this Info
There is a 2.4L DOHC Engine and there is a PROCEDURE Rather than MARKS on the 2.4L and Requires you to Fallow EACH STEP EXACTLY and in a Very Long Texting . But On the> 3.4L Engine and INTERNALY on the 3.4L the Marks Alighn With #1 @ TDC CAM Mark is STRAIGHT DOWN and the CRANK MARK is SRTAIGHT UP < This is Internal marks on the 3.4L Engine
GM does not provide timing chain timing marks, or information to perform timing chain service without the special tools shown in the timing chain service procedure

Good luck with that, it's a big job. There are no external timing marks on the crankshaft pulley, if fact the pulley is not even keyed to the crank. The best way is to remove the timing cover to gain access to the chain tensioner, crankshaft mark and balance shaft mark, you'll need a good three jaw puller to get the pulley off it's a tight press fit. There are darken links on the timing chain that have to all line up with the marks on the cam sprockets, crankshaft and balance shaft. If you try to do it without pulling the timing cover and you let any slack in the timing chain the balance shaft will most likely be out of time. I have the engine out of the car and it's still a big job, I don't know if it's even possible to do with engine in the car. There are 3 small bolts down in the area where the timing chain is, don't forget to take those out. You don't need to remove the cams to get the head bolts out. They tell you to use special tools to keep the cams from turning once chains are removed, a piece of 3/8" flat steel or aluminum plate works. On the back end of the cams there is a flat machined on all the cams when the timing marks are lined up those flats are all in a line. You slip the flat plate under the cams, you may want drill a hole in the plate and bolt it down with the valve cover bolt at the end of the head. I bought a Haynes Manual for that car, it's not the best, but it gives you most of the information you need. Make sure you get all the gook out of the bolt holes use blow gun with a long line on it, like a piece brake line. Spray some brake parts cleaner or carb cleaner in the hole then blow them dry. Oil the threads and the washers or use anti-sieze. When you torque the head bolts it say's to torque them to 22 ft.lbs. and then turn the bolts another 60+60+60 degrees totaling 180 degrees or a half turn. Good luck!

41 is cam sensor code. are you sure the magnet is still in the cam gear? use only quality parts. if the magnet is missing, you need to replace the timing gears/chain.

Well I just looked up the specs for you for the 2.7 ltr. I hope this is what you want.
Cam Caps 105 in.lbs.
Cam Sprocket 250 in.lbs.
Crank Dampener 125 ft.lbs.
Cylinder Head Cover 105 in.lbs.
Here is an illustration of the timing chain set up. Be aware these marks are lined up with the three sets of plated links on the chain. You should easily identify them if you have a new chain. You may have to clean an old chain to see them.
Good luck with this and let me know how it goes for you.
