- Ok, I don't like to call myself a mechanic but I do work on my cars and a couple of other people's as well. This is just a little more difficult for my level of knowledge and experience. So, I have a 1989 Winnebago motorhome (Ford E350 chassis) with a 460 big block and only 40,000 miles. it suddenly started making some unpleasant knocking sounds that sounded like lifters clattering. It's more audible when it gets warm and it seems to go faster when I push the gas but stays the same during idle. It is also more noticeable during idle spears. recently did an oil change and found that the undercarriage is completely wet with some type of fluid....looks like power steering fluid though, anyway, I accidentally put conventional oil in instead of synthetic like it had. Shortly after, I heard the sound and also noticed that the oil pressure gauge was looking kinda low. So then I completely drained the oil out again and put in synthetic oil like it had, but the sounds continued. The oil that I drained out the first time had some flakes in it, but in my opinion wasn't enough to be fearful of it because of the age of it and it wasn't any more or less than I had seen in other cars of this age. After some extensive research, I have decided to try and replace the oil pump tube and screen. I'm thinking it might be the pump but I only have the money to replace the tube and screen for now and I am hoping that it will solve the problem. I'm worried it could be the oil pump or worse, a bearing on the inside just based on the research I had done. I don't want to throw a rod or trash the engine so I drive it very sparingly right now. It has never given me any problems before and has always been maintained well. I'm currently driving it with a little more weight in it than I prefer but I don't know if that is relevant. What do you think the problem is and how do I fix it?

Well it shouldn't have any flakes at all. Hopefully you save some of the flakes. You can send them to an engine oil analysis company and they can tell you what it is. Jared's bearings inside the motor when they're that old and who knows the history of the engine. Generally noise like that is serious. Internal problems. Of course, being that old it could just be the lifters making most of the noise. Any mechanic would tell you by looking at it
