Missing Exhaust Stud - Have you checked yours lately?

Exhaust leak could definitely lead to reduced pressure to the drive side of the turbo. Have run into this quite a bit on ground based turbo diesels.

Similar thing happened last year on my 182. Stud was just gone, not broken. Double nut technique worked. When I got my 337, a loose stud and exhaust leak overlooked by previous owner eroded the cylinder side irreparably and had to replace whole cylinder. I now keep attention to this area where exhaust manifold mates with cylinder.

Good to know about the oversized studs.

Thanks for sharing that. Sounds like it may be more common than I thought.

As you saw, a leak can cause damage to the cylinder head if left unchecked. Another reason to take a good look at your exhaust system periodically!
