This is a 2.25l replacement engine I got when my last one lost its bearings. It starts and runs well, seems to have power enough.
However, over the summer oil pressure kept dropping during idle when the oil had really gotten up to full temp. There were times when the engine would actually sputter after going up a hill. Someone suggested that I might simply have a low idle setting, and I think he may have been right. After the engine was warm, I adjusted the idle just a tiny bit at the carb, and it seems to have fixed the issue. But I can't really get out and test it now because after the last few drives I've had a knock develop.
I think it has been on the edge of my hearing for some time. But it is distinct now. It is coming from the back of the engine, somewhere near the middle top of the block. I can't really pinpoint it, but I think it may be most noticeable at that rear of the exhaust manifold.
Other than the knock, the only symptom might be that if I am at idle, then rev the engine quick a few times, some grey smoke does blow for a second or two. It is faint enough that I would have to have particular lighting to catch it on camera.
The knock itself is medium low in tone, and it has a ring, or metallic sound to it. Video linked below that actually does capture the knock, but not really with the same tones I hear in real life.
The last engine I had knocked from right down low in the center of the block. And it had a deep wooden sound to it.
This is not a priority. I want to get the 110 on the road before I dive into this. But I figured if I get lucky, maybe one of you will know what this sounds like, and maybe I can justify a repair sooner than later.
