Hey guys,
So originally I had decided to do a compression test just for the heck of it. I had never checked the overall health of my engine (40k miles), and I wanted to see where I was at in terms of compression. Obviously the nominal pressure is 199psi (B18B1), and the minimum is 135psi. Onto the results..
Dry compression test:
1 2 3 4
145 115 120 135
Clearly this is not good. Per the DIY I followed from team-integra, it mentioned a "wet" test, in whichyou add a small amount of oil in each cylinder to help create a seal on the piston rings. So if the compression results are the same, you are losing all the pressure through the valves, where as if the results are higher, it means that the piston rings are becoming worn. I was hoping the results were the same so I knew it was just a valve job and I would do it myself. Results of the wet test..
Wet compression test:
1 2 3 4
165 155 150 160
This is where I need your guys help.
What are my next steps?
Does this mean my rings are bad/should i get them replaced/how much would that run?
Would a leak down test help me find anything out more than I already know?
I'm just kind of stuck at the moment, and I know you guys have been such a great help in the past. Please share thoughts, comments, and suggestions if you have any. I planned on getting a new car after I graduate college in the spring, and this may end up speeding that process up a little bit depending on what the issue is.
