Well I tore the rest of the engine down tonight and all I can say is
! Who ever owned it before either knew nothing about Buicks or took it to someone who had their head up their @ss!
As you can see from the pic the filter adaptor was slobered with silicone as well as the rest of the timing cover. The oil passages were half blocked off. Glad it had some pressure at least.
No spun bearings but there was some metal in the pan when I cleaned it. Took the oil pump apart and it looks really nice, considering.
It seems that I've bought the interum block. It's a 20 bolt block with an open lifter valley. Not really and issue but I'd like to know what the deck height is supposed to be. I hope it's the same as the 109 blocks so I can have a little more compression.:biggrin:
