"I have a pair of 1954 vintage marine 471's. The starboard side has developed a leak in the vicinity of the blower - after shut down a fair quantity of oil runs down along the top of the engine. I'm going to pull the blower this fall, but am wondering in advance what type of internal problems I should be looking for.
Thanks!"

"Thanks for the responses. To be a little more specific...The valve cover gaskets show no leakage, and there is no oil on the fuel pump. This engine uses a little more oil than the other, but apart from that it starts and runs pretty much the same. It has always been a little noiser and the noise does appear to be from the blower, not the engine."
