Did a compression test on my 98 Civic LX (canadian) today.
Steps I took were (as per haynes):
1. Disconnect Main PGM FI Relay (its above the ECU in my vintage of civic)
2. Disconnect plug at the distributor (its right behind it)
3. Remove all spark plugs.
4. Plugged compression tester into each hole and turned over 5-7 times.
Readings as follows:
#1 - 190 lbs
#2 - 192 lbs
#3 - 193 lbs
#4 - 202 lbs
All readings rose very quickly, leading me to believe there is a good seal at
the rings and minimal leakage in the valve train. I assume there must be
some carbon buildup in #4 causing a higher reading.
Any comments on my findings?
I did not do a leak down test on it yet.....
Any thoughts are appreciated!
