May 11, 20213 yr comment_621390 it looks like my valve doesn't have a connector for the wire. That is your prop valve. The safety valve is under the MC on the driver side.

May 11, 20213 yr Author comment_621392 I dont have that valve. I guess the previous owner removed it? Link to comment https://www.classiczcars.com/forums/topic/60184-rust-advice-78-280z/?&page=23#findComment-621392 Share on other sites More sharing options...
May 11, 20213 yr comment_621395 Should look like this without the additional prop valve. Link to comment https://www.classiczcars.com/forums/topic/60184-rust-advice-78-280z/?&page=23#findComment-621395 Share on other sites More sharing options...

If I remember right, the wire under the seat is the one that finally made the light go off so I'll plug the G/Y back and see what happens.

May 11, 20213 yr Author comment_621417 I am assuming that it will still work if deleted but not be as safe, correct? Can anyone help with question 2 and 3 in the previous post Link to comment https://www.classiczcars.com/forums/topic/60184-rust-advice-78-280z/?&page=23#findComment-621417 Share on other sites More sharing options...

I can only assume that it was easier make up the wiring harnesses so they would work in many parts of the world although not all of the wiring was needed in every jurisdiction.

May 25, 20213 yr Author comment_622090 Well, I was able to start the engine which is a great thing....but now it sounds like this. Where do I start troubleshooting?

May 25, 20213 yr Author comment_622092 Reading somewhere that this might be an exhaust leak. Is that possible. I do have some white smoke Link to comment https://www.classiczcars.com/forums/topic/60184-rust-advice-78-280z/?&page=23#findComment-622092 Share on other sites More sharing options...
May 25, 20213 yr comment_622095 Sounds absolutely mechanical, not exhaust. I'd check oil pressure first. Don't rely on the gauge. Either plumb in a mechanical gauge or pull the valve cover and be sure there's plenty of oil being delivered topside. Then, do a valve adjustment. If everything's okay thus far and you still have that knocking, I'd start thing rod bearings.

May 25, 20213 yr comment_622103 I agree, that sounds like a clearance noise. Start with valve lash first Then record again Link to comment https://www.classiczcars.com/forums/topic/60184-rust-advice-78-280z/?&page=23#findComment-622103 Share on other sites More sharing options...
