Howdy. Adjusted the valves for the first time on my new-ish to me carbed '74 1.8.
I noticed that the interface between the valve stem and adjuster on the #2 exhaust valve shows some rust or discoloration. The previous owner had the engine converted to carbs and the crank ventilation trap is plumbed to a bung that was welded to the valve cover right next to this valve. Could the water vapors being introduced to this area cause corrosion? Is it something to be concerned about? Thanks! Bryan Attached thumbnail(s)

@burlybryan
I would be more concered about the marks on the valve keeper at the 7 o clock position. maybe the rocker it hitting it. And the jam nut has damaged points. Have you done a compression test after the adjustment? Rust on the valve seats is worse. |

Compression test 90 across the board (IMG:style_emoticons/default/icon8.gif) Engine does consume oil and smokes on acceleration. Sooty plugs. Supposedly was rebuilt 5000 miles ago, but the PO was not very forthcoming with details. |
