Head gaskets blowing on MGBs are well-known to many owners with the familiar bubbles showing between the second and third spark plugs. On my own car, every 12,000 miles, I was forced to replace the head gasket, surface the head and check the block deck for distortion, especially near the head bolts.

Finally, in desperation I replaced the head bolts and the nuts, and knock on English burl walnut-I've had no further problems after 50,000 miles!
