Vance,

What will the compression check tell me.  I've also got a good amount of
smoke but it is primarily at idle and start up, the top end was done about a
year and a half ago so I'm assuming that the lower end is the culprit but am
unsure on what the compression check will tell me.

Thanks in advance.

Mark
