Thanks for the replies guys, it's really appreciated, my car is a 81 300SD. It's been sitting for a month waiting for new axles, it's such a bummer to not be able to drive it now after finally putting the new axles on, and to top it off it's sat long enough there's a rodent in there now eating my wires. I'm a little confused though, are the ports on top of the reservoir supposed to overflow, or is there something wrong with them if they do that?
