Straightness and align boring are two different issues. Straightness can be checked with a precision straight edge or a ground granite block. You also need to check the cylinder mounting surfaces. First check is to look at the center of the case halves and see if the milling marks are still on the flat faces of the bearing journals. If they are smooth the case is junk or at least a lot of machine work is necessary. Since these engine tend to overheat it is common for the case to be shot. Put the case halves together empty. Can you see light on the bearing webs? If the webs are worn, when the case is torque down, the cylinder mounts will become twisted and the heads will not seal properly. Place cylinders on the bosses and check across the top to make sure they are straight and parallel, especially on the left side. As for it being babied, why is it now apart? Dennis

I see no unusual markings in the bearing saddles and I know the history of this "babied" engine since new. are align bores mandatory, or is there a way for me to check the straightness of the case. it's been many a year since I worked one of these. thanks, Thomas -- 1985 Full Westy "Rustfalia" 1982 Full Westy "on the mend" 1972 Honda Z600 2 cyl ------------------------------------------------------------ + To unsubscribe from the Vanagon List send an e-mail to + listserv@gerry.vanagon.com with SIGNOFF VANAGON + in the body of the message. ------------------------------------------------------------ ------------------------------------------------------------ + To unsubscribe from the Vanagon List send an e-mail to + listserv@gerry.vanagon.com with SIGNOFF VANAGON + in the body of the message. ------------------------------------------------------------ |
