3. Re-post pictures of plugs with electrodes aligned the same way like #4. (can't compare plugs unless angle is similar)
4. Squirt small amount of motor oil (teaspoon) into cylinder and crank engine with no sparkplugs for 1 minute before taking compression readings
5. Take and post compression readings for
a. Front bank 1-3-5
a. Rear bank 2-4-6
6. Also advise if you removed any of the lifters. (Compression readings can be erroneous if the lifters have not bled down.)

1. I guess I'll have to get creative here because the debris thats in there is hardened up and isn't gonna come out easily.
2. Yeah mine's like that.
3. Hope these are a "LIL" mo betta:
4. Are you saying this is a way to do a COLD compression test and get fairly accurate figures?
5. Tomorrow.
6. No lifters removed. I wish I would've known about the new 99 lifters when I bought my 98 engine. Missed the good ones by 1 year dammit.
