What year was this 4000Q? I'm not really sure how many years the 5cyl
broke the lower #5 exh. man. stud. I've seen this problem on both early
80's 4000 and 5000 i've owned. I've also heard many 5 cyl driving down
the road with this problem. I'll assume your 4000Q has a similar cast
iron ex. manifold. When I recently rebuilt the head on my 4000 I had to
extract the broken exhaust bolt, using ez-outs. If there's some stud
left here one may be able to use vise grips and a lot of penetrating
oil, and not have to remove the head, otherwise???? I also did not use
a hardened replacement stud for fear of someday having to drill out
the same bolt, except now almost too hard to drill into . There was some
concern about the ex manifold being warped and was considering getting
it planned for $30 but this was just too much over what I had planned to
pay for machine work. I used the ex. manifold, as is. No problems with
exhaust leaks now at 1500 miles after rebuild.
I'm not sure what Cnd$800 is in U.S. but seems a little high for just
pulling the in/ex. manifolds and doing a little machine work (no replacement).
