Details: Been hearing a small squeal when accelerating (low revs) recently. Last night, I seemed to hear a large whirring noise and could smell a small amount of fumes in the cab. Forum research seems to point to the no1 manifold stud. I've had a look under the passenger seat and think I can spot a hole where the stud should be but I'm not sure. It's hard to spot something which is missing!
I've read most of the posts about the studs on the forums, just wondering if this is the problem I have.
Many thanks all!
