How to keep your Exhaust Manifold in check
A leaking exhaust manifolds on a Deutz, Perkins or Deere engine can be annoying. If left alone, this can lead to burst exhaust valves.
Here’s how to stop a leak:
- Check the manifold flanges with a straight-edge and a feeler gauge. (You shouldn’t be able to slide a .010 inch feeler gauge under the straight edge.)
- Clean and resurface as necessary. (A belt surfacer does a good job.)
- Because access to the studs or bolts will be limited, use a high quality performance 12 point socket (with thinner walls). Lower priced imported sockets often have very thick walls making the sockets ineffective for precision work.
- To prevent the bolts from loosening, use a high temp silicone sealant like Lock-Tite.
- Tighten in a circular, hop-scotch pattern as you would on a cylinder head. Re-tighten after 10 hours. If working on a torque-to-yield head bolt setup, as on a Deutz diesel, call us toll free at 1.800.233.6539 for the Deutz Workshop manual. You’ll need it!
