How do i aline cam shafts with cam gears on my b4204t engine

try it and see .. get a printout of the timing marks from the parts store..

You need to turn the engine over and bring it up to top dead center (TDC). Aline your put the chain or belt on. The crank gear will be on you just will need to aline the cam gear as I believe it is overhead cam. Do NOT force the cam gear to turn as you can bend your valves. When you are putting in the distributer as you slide it in it will rotate a bit. Make sure it is alined to where your rotor will be faceing to the #1 position on the cap. I hope you understand. If need be I can look up the timing marks for the cam for you just post a comment if you need. When I say to bring to TDC you turn the engine over to where the # 1 piston is to the top of the cylinder. Hope this helped and good luck.

4.3 liter, right? I think you have it right--see pic below. So it cranks but no fire happening? Did you check firing order, etc.? Getting sparks? Fuel pump coming on? Injectors firing? If you had the engine out of the car, make sure you got all the ground wires back in place, etc.

Well my friend first I need to know a little bit more. Now when you say rubbers, what do you mean? Your timing belt and gears consist of a cam shaft gear or sprocket, a crank shaft gear, and a tensioner located under the valve cover and behind the timing cover that is behind the crank shaft pulley. Can you help better understand which rubber thing broke?

set it to top dead center. there's an access hole to put a 4" or 100mm pin to keep the balance shaft from moving when replacing a timing belt. The other marks are at the cam and crankshaft pulleys.

Or remove #1 cylinder spark plug, put a wooden rod against the piston, when it is at the top of it's travel and goes neither up or down, it is at top dead center. The balance shaft locking pin can then be inserted.

To align both sets of timing marks, turn engine crankshaft to the right with belt on cam and crank. Once you have done this the crankshaft alignment mark (on front of crankshaft gear) will line up with mark to the rear of gear on engine block.The two cam gear timing marks should be alines across from one another. The right cam gear is the intake side and the left side is the exhaust side. After removing the belt turn the exhaust cam down 1/2 notch. Timing mark on exhaust 1/2 notch down from the intake side. Install new belt and recheck everything to make sure it's all correct. Hope this will help you.

usually if the magnet in the sensor comes out it destroys the cam position shaft,(it should have a half moon shape when u remove the sensor from the cam pos/oil pump drive. if the half moon is damaged or missing u must replace the cam pos/oil pump drive, and yes it is timed with the engine. wot i have done is try to locate where the half moon was on the drive it usually leave a trace of where it was. now index where the half moon is at remove hold down bolt and remove the driver assy. install the new drive, clock the half moon shaft to match the one u just removed once u get the half moon shaft where u want it and the oil pump rod alines and the whole housing is down install the hold down clamp. now to get rid if that check engine lite youll have to plug a scanner in and look at the live data adjust the cam position till u have plus or minus 2 degrees

EXHAUST CAM WILL HAVE A NOCH ALIN AT 3 OCLOCK THE INTAKE ALIN AT 9 OCLOCK BOTH MARK ON THE CAM SPORKET MARK MEET EACH ANOTHER, THE CRANKSHAFT GEAR WILL HAVE A NOCH THERE WILL BE A MARK AT ABOUT 12 OCLOCK ALIN CRANK GEAR TO THAT MARK.

on the cam shaft there is a dowel it sopose to be up while crank shaft pulley is aline to 0 in most case damper rubber on crank shaft pulley shifts and cant get timming line up. in that case you get #1 piston up make sure its # 1, then on cam shaft put #1 int. and exh. lobes opposite so int. and exh. are close ,when engine turns exh. opens

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
