My 2.0 engine has 300 miles since rebuild. It has the early sand cast aluminium casing. Since rebuild I have trying to address the issue of operating temps. It has been getting up to 210F. My mechanic has checked many things (so I will not provide a list).
Anyway, in checking out the engine the other day he found that while the crankcase would turn easily by hand when the engine was cold, this was not the case when the engine was warm. If he tried to do this after the car had been running at 190+ the crankcase was very hard to turn by hand. (apparently nearly impossible)
Not being very knowledgable about this, I have no idea why it is getting harder to crank the car in such a manner.
Could anyone tell me whether this represents a problem or not? Is there something that could have been missed in the rebuild?
My engine rebuilder said that the case wasn't milled or anything and to the best of his memory it was all within specs. (note: it was rebuilt a long time ago).
Oh, and also, after my mechanic checked the case and corrected a few things, etc the engine has no oil leaks and only leaked a drop or two a week anyway.
