So after a 3.5 month long exhausting avionics install, it was also due for its annual condition inspection. Unfortunately cylinder #3 compression on the o320 fixed pitch was 64/80. Initially it was even lower until I ran the engine after sitting for 3 months. Unfortunately I’m not the builder or an A&P. I don’t believe he will sign my annual off unless I’m over 70. The air is definitely coming from the oil filler tube so it’s getting past the rings. Anyone have a good shop that does an exchange program or anything else I should look into or consider before pulling the jug? This is disheartening as I just spent a ton of $$ on the avionics and now this
