sorry i always hear people talk about it, and I kinda know what it consists of but can you do it personally? im assuming its something a shop does. Is it expensive??

take off the engine head.
get a woopi cushion and place it on top of the block.
work on each cylinder at a time.
make sure the woopi cushion is completely covering the cylinder youre working on.
press on it as hard as you can.
count the number of times you hear the "ppbpbbbptttptbrrtttt"
(for example..that wouldve been 20.)
write down the numbers for each cylinder.
do that for each cylinder.
post it on HAnet.
discuss.
