I recently bought my ITR from someone who didn't maintain it like an ITR. When I bought it, he reported black smoke so I troubleshooted the fuel system when I got it, after everything it turned out it is blue smoke.
I am thinking piston ring or valve seal. The engine has 126,000 miles and it was never run hard or raced. I would think a honda engine's rings would be good past 126k, or at least that's what I am hoping.
I did two dry compression checks and this is what I found:
Max-270 PSI, Min-135 PSI, Max deviation-28 PSI
Cylinder..........PSI
1...................210
2...................205
3...................215
4...................230
What kind of life can you expect out of the stock ITR rings? The car was said to have been tuned, oiled and kept up regularly, but I don't know for sure.
The previous owner also bought an OBD1 ECU tuned for the ITR of this guy from eBay. I don't know if bad VTEC tuning or anything related to ECU can do this, but let me know.
Would appreciate any help.
Thanks,
Jake
