Default Re: Chasing the knock.

Everyone, including me, has our own idea of what could be going on with your engine.

As I mentioned to you earlier. I have had a couple of cars that looked the same way, and sounded very much like yours.

Many years ago we pulled a Model A out of a barn that it had been sitting in for over 35 years. When we got it running it was making all kinds of different sounds. We pulled pan and it looked like yours, timings gear was also shoot.

We rebuilt oil pump, replaced timing gear, cleaned oil pan, put back together. Started engine using oil I mentioned in earlier post. It ran great, but still had a couple of light knock type sounds. Added rebuilt distributor and leakless water pump. Engine now ran right. The little valve noise it had went away after some driving with the MMO in gas and the high detergent motor oil doing its job.

It’s 40 years later, and that same engine is still running strong. No noise, great compression, no knocks or smoke.

If you rebuild you still are going to need a good distributor and water pump. Plus other things.

If it isn’t broken, don’t fix it. What will it cost you? Gaskets and a timing gear that you need anyway.

Your car looks like it was well cared for. I would take a chance. Good luck. Enjoy.
