Hi All,
i thought this message would be asking the recommended way of removing old and fitting new inlet manifold pipe stubs but i can't quite get there in that i find it impossible to get any tool onto the two lower nuts holding the inlet manifold to the studs in the cylinder head. I've tried open end spanners, ring spanners, offset ring spanners, universal joint and extension bars from all different angles - at the side, from above from below etc; It seems the relationship between the inlet manifold and studs is angled in such a way as to not allow anything even as small as a 1/4" drive socket on it - my 1/4" set only goes to 13mm so if the nuts are larger that may go some way to explaining the problem. I've attempted to remove the exhaust manifold heat shield (the metal one held on with 4 x 8m bolts) to allow more room but without success as the bolt heads are in between 7 and 8mm due to erosion. It would help to know what size these two manifold nuts are vis 12mm - 13mm etc then at least i know using the correct size tool. They are bigger than the 4 x 10mm bolts in the top, that i can tell.
I read the article on aronline by Mike Humble who didn't seem to have any issue replacing his pipe stubs but i'm stumped with this one. I can only assume it is something to do with this part no CAM 9693 clearly stamped on my inlet manifold. This number isn't listed on any of the 3 sets of microfiche i have for the Montego only CAM9708 being listed for this 1987 model. Am i looking at attacking this from below on a ramp with the starter motor, etc removed? Can this inlet manifold be (easily removed) with the engine in situ? Any advice gratefully received. Oh! did i mention, the car has power steering if that's relevant.
As an aside, for those interested, i got into this mess by noticing a slight weep on one corner of the rad which i then had repaired (before finding a new one) and decided to renew the hoses as good housekeeping - most if not all looked as though they had been there since leaving the factory. The attempted undoing of a jubilee clip on one of the inlet manifold pipes resulted in the stub disintegrating in front of my eyes; the subsequent google search pointed me to the aforementioned article by Mike Humble. i seem to remeber reading somewhere not to even think about bypassing the inlet manifold coolant wise but i'm sorely tempted
Thanks in hope
Arthur
