I'm converting a set of 1.7 engine tin to work with my 2.0 spec heads. I've welded the old spark plug holes, and put in new holes lined up with the spark plug center lines. But, there is a hole very near one of the new spark plug holes. What is the hole for? There was a rubber plug in mine. Does factory 2.0 engine tin also have this hole? This is on the right side of the car.

Thanks!

If it is not the CHT hole, I don't know what it is. It looks a little big though.

i'm converting 1.7 to 2.0 also. do you know of any other tin needed? keep us all posted!

CHT sensor indeed! The other engine tin should be the same, assuming the same shift rod and the same type of exhaust.

So the 2.0 tin has the hole for the CHT in the same place as the 1.8 tin?

Yup. Or at least, close enough to be useable.

Hmmmmmm ...... The sensor's in the same place, so ya think the access hole might be, too? The Cap'n

i'm doing the same 1.7 to 2.0 heads. so far its only the 2 peices needed to convert from what i know, we'll see on installation. i bought a set of 2.0 tins (expensive). i only used 1 2.0 tin and chose to modifiey one (1.7) like you pictured due to a few cut out areas that i chose not to repair. (it is rust free and painted and for sale for what i'm in it -$50 shipped). we just cut 3 plugs and welded them in the 1.7 and redrilled off of mesurements from the 2.0 tin
the cht hole is actually over about an inch on a 2.0 but i suppose it wont present a problem in that area.
