Well if it is a 4 cylinder the timing marks would be small hole in camshaft lined up with little dot on head at 12 o'clock position and the crank with the pulley on should line up with 0 on the timing indicator. If it is a 6 cyl then the marks would be- camshafts both with dots up and lined up with indicaters on heads and crank timing mark on 0 with the harmonic balancer installed. Hope this helps.

Look closely at the cover. You will see a small slot. Insert a small flat blade screwdriver, and pry it off. Very easy..

Removal of the plenum is pretty straight forward. You will need to replace the plenum gasket after you remove it; the gasket is not reusable. Personally, if I was going to take the trouble to remove the plenum, I would replace the plugs and wires back there, also.
I know, I have a 93 Camry V6, and it is a real pain to do the plugs and wires with the plenum on. There are no secrets or great tips on the plenum removal, just take your time. Remember that there are different size bolts, and where they go. Please get back to me if you need any more info...Hope this helps, and thanks for choosing FixYa to resolve your issue.
The graciousness of a FixYa rating for my assistance would be greatly appreciated.

Hello. A vibration in the steerign wheel indicates an issue with the front tires. They are either out of balance, and would need to be rebalanced, or it is possible (although remotely) that the tire(s) may be compromised (after hitting a pothole), the belts in the tire may be corrupted. What I would suggest is to take the car to a reputable tire place, and get the balance checked. While the tire is on the balancer, the Tech will be able to see if the tire is out-of-round due to possible road damage. Probably just a tire balance problem. Thanks for choosing FixYA for assistance.
