Timing chain guide broke..jumped time and broke middle gear.

If it is a chain. Check the shear pin/moon key on the crank shaft.

Take all the spark plugs out and bring #1 piston up to TDC. Look at the timing mark on the pulley. If they don't line up, then timing has jumped. If that's the case replace the chain and both the cam and crank gears.

It appears that you got it right but to be sure the check is on the timing chain there are 3 black links If you have it right then the black links will line up with the marks. If not then re adjust the gear that is not correct.- ensure that you have the ignition timing right as you may be 180 degrees out

Turn the crank one more revolution. The two marks will now line up since the cam gear turns a half turn For every full turn the crank makes. A timing chain will not jump half of a gear with out some sort of evidence that it has done so.

I have the instructions but they are long and will not entirely fit in this forum. [email protected]

That motor has a timing chain, not a timing belt. Replacing it requires removing the water pump, dropping the oil pan, removing the balancer and timing cover. Rotate the crank so the dots on the cam gear and crank gear line up at the 6 and 12 o clock positions respectively. Unbolt the cam gear and remove it and the chain. If you need to remove the crank gear you can use a three jaw puller or something similar to pull it off. Reinstall the crank gear lining up the gear with the keyway on the crank and press it on with the appropriate tool. Install the cam gear with the chain and make sure dots line up again. It may be necessary to remove the valve covers and rocker arms as well to rotate the cam shaft if need be.

Unless the timing chain suffered a catastrophic failure, ie broke into many pieces, you should not need to replace the cam and crank gears, the tensioner arm and tensioner. The timing chain and guide I can agree need to be replaced, but without a physical examination, you can't just say "replace all these parts". If you do let this mechanic do the work, insist on him giving you ALL the old parts. Then take them to another shop and ask their opinion. You may find the mechanic is honest, but I suspect not.

It definately sounds as though you've got your cam gear set 180 degrees off.When your timing is at top dead center your crankshaft will be at TDC on the guage, the cam gear will have both of the lobes at 10:00 and 2:00 away from the surface of the valve they serve on the number one cylinder. This can only be see if the valve cover is removed, which at this point I'm sure it is. Thank you, Dana

i had the same problem. had a knocking on the engine and let the vehicle sit until i had time to look for the problem. my unknowing mom took the car without permission and the car broke down on her. as it would turn out the upper timing guide rail broke off and damaged the cam gears and broke the upper timing chain along with damaging both the right and left lower chain guides, and the tensioner was also damaged. i would recommend that u inspect the lower chain to make sure that everything is good.

if you mean the timing chain then on your crank gear and your cam gear there will be a mark on each sometimes they look like a dot the dots need to look like this for perfect timing ( . . ) this will be there closest position. Your crank turns once all the way around (360 degree) and your cam gear will do two complete revolutions to the one of the crank gear. so when you set your marks as above when you turn the crank one half turn the mark on the crank gear will be at the bottom and at the same time your cam gear will have made one complete revolution, so when you turn the crank another half turn your cam would have turned again a complete revolution and the two marks should be at their closet point again.
