-350-Ed- Posted July 14, 2015 Share Posted July 14, 2015 Good evening guys and girls, as someone with very little mechanical knowledge I'm worried about a sound in my engine bay. There are 2 main symptoms although they could of courses be 2 separate issues and unrelated: -The rattly sound in the engine bay, almost sounds diesel-y -The engine sounds and almost feels rough right at the top of the rev range. I've added a short youtube clip of the engine bay noise,. Now whilst it's hard to diagnose a sound over the internet and through watching a video, I'm hoping someone smarter than me when it comes to engines can identify what he rattly sound could be and what I could try to fix it. One point to mention, this isn't the clutch chatter that goes away when the clutch is pressed. https://www.youtube....cneLEqCE Quote Link to comment Share on other sites More sharing options...
GT4 Zed Posted July 14, 2015 Share Posted July 14, 2015 Sounds rough! Could be valvetrain related, bottom end bearing related or even just the belt/pulley related. Your belt looks new has the been changed recently? I had a ticking noise that turned out to be the painted section of the Continental belt going over the idler pulleys. A few squirts of WD40 on the back of the belt and it disappears until the oil burns off. The continental belt is noisier than the Gates anyway as the non ribbed backside is hatched/groved and transfer noises from the rotating assembly. The key questions are - does this happen only on idle? - is the car running ok otherwise? - have you had an eye on your oil level all the time? Ultimately you will need to take it for a live inspection with your nearest zed specialist as it just guess what the issue is. Quote Link to comment Share on other sites More sharing options...
-350-Ed- Posted July 14, 2015 Author Share Posted July 14, 2015 The belt was put on last October time (about 2-3k miles back) by the kind folks at the Zed Shed, it had a full service and every fluid changed. I think the noise has been here since I've owned the car but because it had a horribly blowing exhaust until about 6 weeks ago when I had an Invidia system installed, I think the noise was somewhat hidden. Oil level is fine and is looking very healthy. As I mentioned above, the car sounds a bit rough right at the very top of the rev range, but this could be something else. One thing I know is that my cats are still original and the Zed shed chaps removed the heat shields as they were rattling a bit, so maybe it's time for some HFCs.

Juggalo Posted July 14, 2015 Share Posted July 14, 2015 What he said. Take the belt off and run for a very short time. Or could be incorrect timing, but unlikely with it being chain. Or leaky manifold. Quote Link to comment Share on other sites More sharing options...
