From a point at sea, to the circles of your mind, this is Martijn:
Have you ever tried to remove
a (square) air inlet manifold of a B27E. One nut is almost unpossible to
reach.
I used to have a 240 with the B27E engine. Actually I liked the
engine, it semed well suited to the car, and I got it up to a fairly
high milage without any of the more commonly reported problems. But it
seems that few share this view. And it returned abysmal MPG.
The only lasting trouble I had with it was, indeed, with that big
square inlet manifold. My memory of it is that the bolts that held it
down were stupidly short, stupidly small and stupidly too few (four
bolts for a six port manifold is patently poor design). It was
impossible to clamp the manifold to the block and make all six ports
airtight without stressing and eventually stripping the threads.
In the end I dispensed with the bolts and made a couple of clamp
plates that went across the top of the manifold, tied down to the
block with long J-bolts. Didn't look pretty, but did the job.
