and watch how far he pushes your engine....I know..

was funny how he did a base line on my old engine...said it was down from a year ago...pulled the valve covers and readjusted them...oil looked fine, just had some weak springs...he ran it up again, this time at ear splitting RPM and said he hears something..

pulled the covers again and here its loaded with bearing material...I was PE Oed.. tore the engine down and here, there was a snapped off rod and damaged cylinder...was not like that before that session...

so I learned the hard way...
