Hi there,
Did a compression test on my 98 Civic LX (canadian) today.
243000kms (151000mi) 5 spdSteps I took were (as per haynes):
- Disconnect Main PGM FI Relay (its above the ECU in my vintage of civic)
- Disconnect plug at the distributor (its right behind it)
- Remove all spark plugs.
- Plugged compression tester into each hole and turned over 5-7 times.
Readings as follows:
Min 160 Max 194
#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!
