Well, I was out for a nice drive after changing the front wheel bearings
last week and decided I would take a trip on the interstate. Everything was
going fine till I hit a hill doing 70mph and white smoke just went
everywhere(including inside the car) so I pulled over and found a nice river
of antifreeze running down the side of the block. It was coming from the
head and block mating area, so I have the new headgasket. I did a little
research and the problem only occurs over 65mph going uphill, so I am
wondering if the head or block surface area may be warped slightly and
separating when that amount of stress is put on the engine. Anyways, I will
check that when I take it apart to change out the headgasket. If that
doesn't work, then I will just order an aluminum head from Moss and have the
bottom end rebuilt. Any suggestions are welcome.
Thanks
