So I have been battling a leak at my thermostat for quite a long time. Last year I took the housing to a piece of sandpaper that was stuck to a piece of glass, so that is perfectly smooth. I then tried taking the housing to to the intake with sandpaper stuck to it and tried to make sure the intake was true. Hard to do with such little space. Well it was still leaking after I did all of this, even though it took a while to show up.

I pulled the housing today and the housing still looks really good, but the intake doesn't look all that great. My thought was to pull the intake and take intake and housing to a machine shop and see of they could true them both up and then make sure to cut in the groove for the thermostat to sit in to make sure it doesn't sit up too high.

Any thoughts on this? Is there a decent way to true it up on the car without removing intake?

Here is some pictures of the intake and a picture of the still clean housing.

Thanks,
