Re: Any idea on what this knocking is 72 C20 350
Engine has not been sitting. Been running it all summer. Although it did sit for about a week maybe less before I ran it on the day that this started happening. This started last Friday on the highway going about 65-70. I agree with you because sometimes the ticking/knocking misses its not always steady but it does increase speed with RPM. I also did just put some oil treatment in it this morning. Doesn't seem like it did too much. How do I check the flywheel?
