What all is needed to build one for cheap? And how exactly? Also will a bike pump work instead of an air compressor? I know you only put 5-6psi or you risk blowing bottom end seals.
How long ahould I wait as well? I saw one guy say wait an hour, some guys say 5-10 minutes. How many psi can I lose (if any) and be good?
What should I use to spray around the motor inside and out and not ruin anything?
I know it seems straight forward, but I have never had to do a leak down teat by myself before... so some advice as well would be great.
Thanks.
