I've got a 429 ford in my hydro, and have just put on a tunnel ram and tweaked the carbs. I took it out today (second time since I've had the boat), and noticed the the oil pressure when cold gets up into the 60's.. when we were out on the water with it warmed up (oil temp of 180 or so), it would give 40 or so at idle or slightly above. When I got on it, and up to 4500 to 5500, it would drop to almost 30. I'm a bit concerned. The pump is almost new. There is a possibility that some blowby gasoline got in the oil with a carb gasket issue that dumped tons of fuel in the front 2 cylinders. It seems to run ok, other than minor carb tuning issues with going to a tunnel ram from a dual plane. I would think that any of the gas in the oil should have burned off.. we were out tooling around for an hour or two. I'm thinking I'll just replace the oil and filter and see what happens. Any thoughts? What oil weight are you guys running? What pressure do you see?
Thanks,
Bryan
