I have a 1990 Sentra, I found out today that my clutch has bit the dust. I've been quoted from $563.00 to $900.00 to replace it. I checked for the price of the parts and they only came to $90.00. Has anyone replaced the clutch is this year sentra before? Also according to the haynes manual the PVC valve should be on the valve cover. It isnt, I have searched and cannot find that $#@#$# thing. Any help would be VERY GREAT.

I'm replacing the clutch on my 91 nissan sentra right now. It's really easy. i spent $180 on the clutch kit. Just remember to get your flywheel resurfaced and replacing everything.

And the PCV valve should be just about the fuel rail by the crankcase.
