Re: Oil in head bolt holes
Yes it could or could have gotten oil on it upon removal. The reason you don't want oil in the holes on installation is because when you go to torque them you will get a false torque due to oil is not compressible and acts like the bolt is bottomed out but it really is not. Then when the oil finally works it's way out of the bolt hole you have a loose bolt/stud etc.
