My seemingly never ending David Brown 885 wet stacking problem. Finally got around to installing a hotter thermostat (for a Toyota application, I think), we'll see if that helps tomorrow. Meantime, the exhaust manifold is sooty inside but dry even though the manifold to muffler connection is dripping black slime and the muffler is very wet inside. As I was inspecting things before dropping the hood back on I noticed the block/fuel pump stake marks do not line up. The pump mark is misaligned with the block mark by a stake mark width. Viewed from above, the pump mark is clockwise of the block mark. Could this have any bearing on wet stacking?
