So the other day, my roommate and I were bored and decided to do some compression tests. Figured I'd record them here and share them with anybody who gives a damn.
Here are the results from my 90 N/A with ~60k since a full Toyota dealership rebuild. 291,000 miles on original block. I did the test twice, about 30 mins between. #6 had oil in the spark plug galley and therefore was tested "wet" because I failed to soak it up before pulling the plug.
1: 172
2: 170
3: 151
4: 158
5: 167
6: 178 < wet
1: 160
2: 159
3: 151
4: 156
5: 165
6: 180 < wet
The first test yielded a very low #3, but after waiting about 30 mins, the second test indicated no such problems. (TSRM specifies ~156psi with a maximum variance of 14psi)
I could have tested each cylinder wet, but I had just replaced all spark plugs and frankly, didn't feel it was critical.
Looks like the motor is in pretty good shape, though I may need to keep an eye on #3. The test may explain why my N/A isn't as slow as the others I've driven. :biglaugh:
Anyone have any thoughts?
