hi, just got a '90 7mgte manual in black/pearl mica, i think i got a BHG (gives a little puff of smoke sometimes on down change) freind thinks it could be the valve stem oil seals? either way i'm gonna have the head off. get it skimmed and new gaskets sets in. got the same heater problem (fan blows but only cold air), i'm a bit of an novice when it comes to getting my hands dirty and all the technical stuff. as i'm in the uk, i'm guessing that the vsv is going to be swapped over on the opposite side as we have our sterring wheel on the right here. thats right yeah? and where exaclty is it, can i access it from the footwell inside or in the engine bay? any help/pics would be great.

It is located next to the heater water valve, and always feeds vacuum to the water valve...except when the controls are set to 65*, for max a/c cooling. That's why you don't really need the vsv. Just bypass it and hook vacuum directly to the water valve. Out in engine bay on firewall.
