Robert wrote I would recommend that if you are going to replace your head gaskets, go ahead and pull the barrels off and replace the seals under the cylinders. Also pull the rods off and put in new rod bearings and bolts and nuts Robert and the list while pulling the cylinders and checking the rod bearings is sound advise in general I caution the week end mechanics about tugging the jugs and thinking that they can just reinstall them without pulling the pistons or going threw great pains to get the jugs back on the pistons while the pistons are still on the rods. I have never heard of of the lower cylinder O-ring leaking and have never seen any signs of leaking in the engines that are stripped here at the shop. I have often written about replacing the 2.1 rod bolts and nuts BUT that does not cure the problem of the big end of the rod being out of round. the connecting rod and cap needs to be ground flat at the matting surface and the big end then needs to be resized to the correct dimension Bob Donalds http://www.bostonengine.com as always all rights reserved. |
