First off I'm a girl. :) My 2.0 non turbo engine has a bent valve. I have been asked to pick up the valve. But I need to know if its for the intake or the exhaust. I know the guy how is going to fix it said he will have to sand down the cylender that it goes in it. The car sounds like it knocking when driving or sitting still. The guy who is going to fix it is at work right now and I'm suppose to order this part right now. Is it an intake or an exhaust valve?
no way to tell ...and he doesn't sand down the valve ...it's called seating or lapping. and it's not done to the cylinder... knocking could aslo be a hung lifter.
tell him that you dont sand down the seat.if he does,then he could get it so it wont seat right.he needs to lap the seat.now 1 of the valves are smaller then the other.if it backfires through the exhaust then its the exhaust valve.if he know how to do it,then all he has to do is take a piece of paper and hold it up to the tailpipe and see if it sucks the paper in.
