Help! Check Valves - Emission

[Peek81]

Replacing the 3 engine check valves on my 81. one for each exhaust manifold and one on the converter pipe to catalytic. Can I use the same part # for all applications.Dorman brand seems to leak.Ecklers has Delco sku -25-105882-1 seems like a better choice.

Check Valves

Just received info same check valve will work in both applications.

Rockauto.com has those check valves.

I replaced mine several years ago. I got them from Chevrolet. Don't know if they are still available but would guess that they are if Eckler's has Delco. The originals were gold and the replacements were satin black. Worked just fine so far.
