Q: Timing chain positioning

This system is a bit complex. I can give you some instructions, but I highly recommend getting a hold of a repair manual or purchasing a yearly subscription for just your vehicle from AllData. It is only $25 for a years subscription from AllData.

There are two separate sets of marks on this system. One set is for aligning the timing chain to the camshaft gears and the intermediate shaft gear. There will be marks on the chain that raps around the crankshaft gear as well. These marks will not line up after you turn the motor over.The other marks are on the inside of the camshaft gears and align with the cylinder head parting line. If you were to draw a ling through the center of both camshaft gears, they should line up with that imaginary line.

The crankshaft key way should be aligned with the mating face of the main bearing cap. You can confirm it is in the correct position by verifying the number one piston is at top dead center. If you have removed the balance shaft timing chain, these marks really need a visual diagram to understand where they should be aligned. Without a diagram I am not very confident it can be explained very clearly.

This may be difficult to to follow, so again I highly recommend purchasing a repair manual in digital form or a book. If you feel this is over your head, I recommend the following inspection to help you out. Timing chain replacement

Good luck! I hope I was able to help you.
