    fuel in engine oil

    Thought I'd try one more time on this one. My 2004 Volvo Penta 5.0 GL-D (w/stock holley 2 brl.) runs great at/below 4000 RPMs. Above 4000 RPMs it intermittently boggs down - not much RPM change indicated on tach. When I bring the RPMs back down it runs fine again. I am also noticing some...

    Fuel in engine oil and bogging down at high RPM's

    2004 Volvo Penta 5.0 GL-D Some time ago I posted a thread about gas in my engine oil and overheating at high RPM's. Well, after changing impellers, thermostat, tightening hose clamps, checking risers, etc, the overheating at high RPM problem turned out to be a leak in the water intake in the...

    Volvo GL-D Lifter Noise

    I posted a thread a couple of weeks ago regarding lifter noise. Someone suggested an overabundance of oil would start the oil to froth and/or aerate and could cause such a noise. Well, I checked the oil and it was overfull (atleast a quart). The oil has NO viscosity. The boat was only used twice...

    5.0 GL-D Lifter noise and power loss

    Looking for some advice, I have 2004 Stracraft Aurora 2210 with a Volvo Penta 5.0 GL-D (carburated). Other than a bad thermostat, this is the first problem I've had with the motor. I've had this problem the last two times I used the boat. The first time it happended I was running the boat at...
