[Fot] Race Engine Refreshing Frequency - compression results

[Tony Garmey]

It’ll never be any cheaper than right now ! If you’re planning on a similar number of events next year - pull the head and service the valve train and change the bearing out.

 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:

  1.  210
  2.  225
  3.  195
  4.  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?
