Lumina Valve Adjustment Q. My previous question was: 4L60E To Turbo 350I plugged the sensor into the harness and tied it up under the hood but the light still comes on. But it doesn't come on untill after 3500 rpm same as before. Does the speed sensor actually have to be under the car? What else can I do? One more question my driveshaft was cut down by a couple different places and I still have a vibration. Will a driveshaft from a 200R4 work?

Then figure out how to adjust them with engine warm and/or running. I'm sure it is going to be messy. I would like to do this to my car. I'm sure that I should have a pro do it, but they won't or want a mint. Sorry, I don't own a mint, have to do it my self. Not sure of the right technical language but I have a good understanding of my car. If you have any? I'm all so looking for all the sub-frame mounts (parts suppliers) adjustable fuel pressure regulator.

Thank you...

A. I'm not sure what you are trying to accomplish with the adjustable rockers. There is a procedure to do this in older service manuals. Turn engine to TDC and you can adjust half the valves. One revolution more on crank and you can adjust the other half. As long as the cam is on the "flat spot of the lobe you can adjust that valve. 3/4 of a turn AFTER all the lash is out. As for pressure regulator, don't know of an adjustable one. Check at a speed shop. Bushings should be available at a GM dealer.
