Compression Test Reading high on 1 cylinder
Am checking the state the engine is on MY01 and I started with a compression test. Just a dry test. Engines already hot, injectors off, coils out. I got a reading like
180 - 181- 182 - 205.
fairly rough numbers but you get the idea. The manual states 28 variation max. Its not past 28 but its pretty close. Any ideas?
edit: took off valve cover, has 100,000 miles on and the retainers are still good wtf. Who knows the difference between ap1 and ap1 retainers?? like what do they look like. Spark plugs look good too.

I have not seen AP2 retainers, but I would guess that they look very similar. I'm sure I read somewhere on here (written by Billman250) that AP1 retainers will last fine as long as the engine is not abused or over revved. I have AP1 with 68000 miles and retainers are fine, I checked them just recently.

Valve clearance is good, and I looked at a pic and determined I still have the ap1 retainers. i seen a lot of guys who read 180 on there ap1 and its fairly normal. Im being bold and saying the engine is healthy, but wanted a second opinion
