Thermostat housing issue

Well last night was fire the engine night on my complete restore. I turned it over and bam, it fired. So i decided to add the water so I could fire it, adjust timing and such. Problem is that when the coolant reached the T-stat housing is started leaking. As I sat back and thought about it, I had a heck of a time getting the radiator house on that housing. It seems the clearance between the housing, valve cover and head are way to tight. Why would this be so tight? 258 4.2l

This picture was taken for a different reason, but I think you can see the difference between yours and mine (1977) Yours sweeps back toward the valve cover while mine doesn't They're square to the mating surface of the housing.

Looky here:


I'd rather be lost on the trails than found at home!

Mine is the same for a 1981 to 1985 258ci. It looks like the right part. It may be the extra clearance was needed for AC or air pump equipped vehicles which have additional belts and gubbins on the front of the engine.

Thanks for the help and pics. I since have reset it with gasket sealant and no leak. I fired the engine got the temp and pressure up and still holding strong. I still don't like it though. I think I'm going to track down a straight housing. Oh and by the way the engine fires immediately and runs strong. Slight lifter knock but ill investigate that tonight. Very rewarding seeing two years of labor coming together.
