camshaft installation problem question?

[calebmilla]

What happens when camshafts are installed 180 degrees upside down? Does the motor run at all? I think mine might have been installed upside down, but I didn't think it would be possible since it doesn't seem like it would run at all. Is there anyone out there that has alot of experience with camshafts?

you shouldn't be able to install the camshafts 180 degrees out since the cam has a dowel pin that matches up with the gear. You can be 180 degrees out if the cam was not lined up properly when the timing belt went on. I don't think the car would run if that was the case. You could be 1 tooth off on the timing belt though since the gears tend to try and turn when you tension the belt.

Is your car running? I suggest you check the base timing with a timing light.

Thanks for your help, but I found out the person who did the timing belt last installed it with the cams turned upside down making the marks on the cam gears point down instead of up and making the timing advanced 60 degrees. The only reason why it ran was because the computer was retarding the timing to compensate but it still ran terribly. Thanks.

Thread moved. And do us a favor, don't ever go back to that guy who did the work again.
