Odd cylinder pressure.

Post by DaveEFI »

A mate reported doing a compression check on his 4.6 RV8 the other day.
A couple of cylinders were high at about 200 psi and one low at about 140 psi. The rest all around 160 psi. What could cause the high readings?
He's trying to chase a vibration under load at a certain engine speed. Which has just appeared.
