Re: Retorque Heads
Bluebell,we reco quite a lot of the small Japanese diesel engines in our shop. It's very scary after, say, a spec of 40NM+90deg+90deg doing the 2nd 90deg. Even with the correct lube on the threads and under washers,if fitted,some bolts come down ok BUT others creak and grown and you would swear that they will break. Touch wood it hasn't happened yet. As a side note to the retorque procedure we put a small paint pen mark on the bolt head and on the head next to it. That way we we can see if the head gasket is still coming down.
