Compression numbers
Hi!
On a smoothly running '99 NB 1.8 running 10psi of boost at 120k miles, I did a compression test with a new tester and it read 165/180/175/185. Wet, the first cylinder read more like 175, 180, but also I feel like I could have cranked the dry cylinder long enough to get a little more pressure. I truedd to keep cranking time even. So I assume there is some ring wear.
However, I really don't want to get a new engine or tear this thing apart. As long as I do all my maintenance and constant oil changes and stuff, should I be fine to just keep running this thing?
Also, anyone used ring sealant fluids before? Are they fake?

I wouldn't say it's particularly bad. What order did you test compression in? 4, 3, 2,1?
I ask because when I tested with a weak battery, cranking speed decreased as I kept going and continued to get worse numbers unless I kept the battery topped off. Now I always test 1, 2, 3, 4, 4, 3, 2, 1 to verify that nothing looks out of the ordinary due to a sagging battery voltage.
