Re: TR-6 Engine Lifting Mount Bolts - More Info...
Well since you were all so kind to commment, I thought I'd tell you what I discovered. Removal of the bottom bolt did show it was wet, in fact I got a slight "pisst" sound when I first loosened it indicating that it was under a bit of pressure from the other side. This concerned me and I wondered if like Tom said above had I fractured a water jacket or oil galley. The bolt I reinserted from the original assembly is 3/4" long from the bottom of the head to the end. I originally put it in with a lock washer, 1/16" inch. So it tunneled in probably 11/16's before stopping. As an experiment, I screwed in a longer bolt and sank it - by hand - to 3/4". It probably could have gone slightly deeper if I'd put a wrench to it. So arguably I don't think I bottomed out the first screw and breeched a galley, or jacket. Like Paul above, I've always wondered why the area above and to the rear of the fuel pump seemed to collect oil. I've been cleaning it for years along with the area on top of the block, below the head, where the tranny connect. I discarded it as maybe a leak from the oil pressure line, whatever. I suppose this problem is not limited to airpump equipped cars since this is a drilling in the block. Someone correct me if I am wrong. Anyway, I reinstalled a shorter 1/2" screw, in both holes, complete with fiber washer (bottom only), flat outer washer, and Permatex. I'll fire it up tomorrow. Thanks to all.
