My old A4 did something similar when I had WATER in the oil pan. Somehow is got syphoned up through the seacock when it over heated. ~Dan --- On Tue, 7/27/10, Mark Robertson <[email protected]> wrote: From: Mark Robertson <[email protected]> Subject: Re: [IC27A] Re: Engine Trouble To: [email protected] Date: Tuesday, July 27, 2010, 2:32 PM In the automotive world the cylendars should be within 10lbs of each other so if you have one that is more than that it could be the problem. The other issue is that the plugs may be worn and need to be replaced. Sometimes one step hotter on the plugs will fix the problem. >>> Wade Rogers <[email protected]> 7/27/2010 10:30 AM >>> Matthew, I too have an Atomic 4. Fortunately, it hasn't given me that kind of trouble? How many hours on the motor? If there are a lot of hours, given that the oil pressure gauge fluxuates, you might have a blown head gasket or a cracked engine casing. This would allow oil into the chambers, foul the mixture, and cause the engine to lose compression. If you can get a compression gauge and check each cylinder, you might find the pressure in one or more pistons is not up to specs (don't have the specs on me right now). It could be any number of issues but it does sound like oil is making it into the cylinders, then out your exhaust system, hence the soot on the transom! My 2 cents worth!
