I have a year 2000 mpi. One of the thermostat gaskets blew recently, and after replacing them with some difficulty (tiny leaks), they are now leak free. What I am getting now though is steam escaping from the expansion tank cap, which suggests that there is another problem at the root of all of this. I haven't taken the rocker cover off yet, but there's no water in the engine oil, so I'm not sure it's a head gasket problem.
Does anyone have any ideas at this point? Cheers all
