I've got this bubbly flaky engine as clean and greaseless as I can ("simple green" delicate degreaser fyi). Timing cover looks like it might be weeping but I'm having trouble finding any other source especially the bad one. Looks like it's under the left cylinder base gasket but, I've read numerous posts on the subject and have found that a common leak is the oil cooler lines/oil lines/coupling gaskets. There is no evidence of that... I do know that the previous owner had the rings replaced on the left cylinder and the heads had been re-torqued fairly recently. I was hoping the leak was as simple as the timing sensor so I had smeared a light coating of silicone sealer between the shim and case. Also totally unrelated while I had her sitting there idling thought I'd check the charging system. Headlights brighten up with revs but last time I checked it was perfect (12.9 at idle up to 14.2v at 3k). Today it was sitting at 14.26 at idle and didn't change much when revved. This can't be good... I know I'm like most of us Americans who believe that a little is good but a lot is better. But in this case.... I'll try and post some pics, any help is obviously appreciated. Note the "foot powder trick" showing very little weepage on the timing cover, last pic is back of the case with a small amount of oil
