OK, so I pulled one of the valves and the valve and guide slipped right out. The guide then slid right off the valve easy. So they were not seized up. The valve is not bent and the face and valve seat look ok. The guide is paper thin. The side of the guide near the valve face looks burnt for about a third of the length and the end is opened up a bit.The valve has numbers near the tip, 01769R and 1-1-W1-1. Now as I recall, the motor only had about 5000 miles on it, and the reason I pulled it out was because it would go two or three blocks and all the water would dissapear and it would get hot. Now it appears some of the head bolts did not have any sealant where they go into the block. So my question now is would overheating cause the guides to come out like that? When the motor was put together(about 7-8 years ago) I had the heads done at a local shop and some guides were installed, I dont remember how many. When it started overheating I would shut it down and have somebody pull me back home. I know its asking a lot with no photos, what do you think?
