YM 1700 head gasket

Maybe he was just doing as the manual says and droping the oil pan every 150 hours or whatever and cleaning/making sure the pump screen was clear!!

But i think the gasket scraping marks could be there for a long time if not indefinitly? I have pulled stuff that i was the last person in and could see signs of where i had done it before, weather it be old scrape marks bits of old gasket that were left or some other sign.

Still no word on the head- shop said it would be ready by the end of the week- they just didnt say which week.
How much play should I feel in the cam followers? Should I be able to push them up and down with my finger? What about wear on the followers? While I have the head and oil pan off is there anything else that needs or I should at least visually inspect?

I have a Yanmar 1700 and as soon as i start it it, Coolant comes spewing out at a high rate of pressure. Is that a sign of a blown gasket?

Also, be sure to use the compression release every time you crank it, to blow the water out of the cylinders before it starts. Water cannot be compressed and will break the rings.
