147 1.6 Head Questions?

Hi All,

Working on the wife's 147, after the water pump failed and threw the timing belt off. On inspection there were two inlet valves bent (No4), I removed the two valves and while the cams were off I turned the head over and filled the combustion chamber with water to check if any other valves passing. After an hour chambers 1 + 3 were holding the water but chamber 2 had passed a slight dribble thru the exhaust port. (slight burnt valve seat?)

Question:- Is this a good way of checking that I don't have any other bent valves? as the remaining valves look to be seated properly. I then put the camshafts back in to check the operation of the valves, but there seems to be more resistance than I expected when the valves were being depressed. (I'm more used to the Fiat 8v twin cam engine) Should I expect more resistance with a 16 v head? or do I have a slighty bent valve?

Any Thoughts?
