[QUOTE="88CR250#13, post: 1260097, member: 83723"] I bought CR250 from a kid a couple of weeks ago. He said it was an 88 but after looking at the vin, the year code is "M" which makes it a 91. Anyways, I got it cheap because the water pump was leaking. He said it needed a new water pump shaft. I replaced the water pump shaft, seal, gaskets, and the oil seal. Put everything back together and started it up. Still leaked. So when we took the screw loose to drain the coolant, it sprayed out with a lot of force/pressure. So I topped the coolant off and left the radiator cap off and started it back up. No leaking. Put the cap back on it would leak. I did notice that little bubbles were coming out from around the head gasket. Could a bad head gasket cause to much pressure? I don't know much about motors. Any help will be greatly appreciated!! Also forgot to say that there are air bubbles in the coolant too. I can see them in the top of the radiator. Thanks, Tuc [/QUOTE]
