Hello All,
I'm new here. I have a 2001 GS Spider Convertible w/ 2.4l engine 130k miles. Automatic trans. The balance shaft belt broke so I replaced it, and timing belt (was still intacted when removed) and water pump. Set the timing according to some vids found on youtube. Got it all back together, now when it starts it vibrates bad. I made sure to set the timing before I removed the old timing belt, just to make sure everything lined up correctly. Any suggestions. Also, have some other problems to figure out. But, that can come later. Thanks

I don't have the 4cyl but could the balance shaft be out of time with the rest of it? I'm assuming they need to be timed together since they need to be in sync to properly balance the rotational mass from the crankshaft.

I'm thinking the same thing but I set the timing marks just like the youtube vids showed and as I read in the forums.

The 4G64 has two balance shafts. The one with its own belt is easy to line up, and the second one is part of the oil pump assembly, and is gear driven by the main timing belt. The wheel can look in time but the balance shaft might not be. There is a bolt you can remove on the front of the block near the exhaust manifold, and while all timing marks are lined up, you should be able to slide a screwdriver in the hole free and clear. If you hit something while sliding in the screw driver, its not correct. You can also use the gravity check, and while the timing belt is off, and the arrow is close to lining up, turn the wheel left or right, if it falls back close to lining up its good, if it lands 180 or straight up or down, its not correct. Turn it 360* and try again. There are good Youtube videos explaining the timing on these.

Ok thanks for the info. I figured that all the timing mark were in the correct spots when I removed the old timing belt that everything should be ok. But, I'll to check into that just to make sure. Thanks

That gravity check is fool proof and theres no risk of something falling into your engine. Its certainly the problem.
