Maintenance updates (coolant leaks, another misfire)

I noticed a fair bit of coolant loss and discovered the main radiator hose was leaking. Replaced both radiator hoses as well as the radiator since it was suprisingly cheap and I'd heard the plastic can crack when the motor mounts go. I replaced both the motor mounts and the transmission mount, they were in bad shape.

The car has developed a misfire again, and so I had Clark rebuild my voltage transformer just in case but that wasn't it. Since I had new coil packs I was getting a bit edgy, but decided that it was time to change the valve cover gaskets since I had seen the oil leaking into the plug wells . When the coil packs were removed, noticed the turbo water line seals were leaking. The o rings were in pretty bad shape . But also, one of the MAP sensors on the intercooler line had physically broken .Misfire solved .

You need to order 28 bolts when changing the valve cover gaskets BTW
