I just did mine, I had one exhaust valve at .08mm and one intake at .45mm.
On the 94 5SFE intake clearance is 0.19-0.29mm and the exhaust is 0.29-0.39mm. It should be written on the emissions label under the hood. Heres a video of how to remove the valve cover, I never did make one for the valve lash like I planned. http://www.youtube.com/watch?v=4DFhHncL8l8 You will need use a feeler gauge set to determine the gap between the cam lobe and the valve shim. Write it all out in the layout of the 16 valves, you will only be able to do half with the engine at TDC and the other half with the crank rotated 360 degrees. Next you will need to remove the camshafts to be able to measure and replace the valve shims. On any valve that was out of spec you will need to use a pair of calipers to measure the thickness of the shim and swap for a shim that will bring the clearance back into tolerance. In the case of my .08mm exhast valve which was .20-.30mm too small, the valve shim was 2.7mm thick. The .45mm intake clearance was nearly .20 to .30mm too big and had a 2.9mm valve shim. So I simply swapped the two valves shims. The exhaust is now at .29mm and the intake is .20mm. You may have to order some shims from teh interwebs or a local machine shop if you cant just swap existing shims to bring all the valves into clearance. |

On the repair manual, it's said to use the valve adjustment tool to remove the shims without having to remove the camshaft. Wander where you can get that tool. I've only found the ones for the Toyota trucks. -------------------- |
