[Fot] Race Engine Refreshing Frequency - compression results

[James Trudeau]

I finished a 9 weekend race/school/track day season that started in April and finished at Thompson in October with no obvious performance problems. Total of 38 engine hours including warmup, grid, race, cool down. 

Did a dry compression test today:
210
225
195
200

I get some oil blow by at the valve cover cap and maybe some drips from lower end seals (not sure if oil starts at valve cover). 

I’m sure I’ll hear a suggestion to do a leak down test and / or wet compression. 

Oil filter forensics?

In the absence of obvious issues, how much of a tear down is warranted?
