Doesn't sound internal to me. As Double R Ron mentioned I think it sounds like resonance being transferred into the chassicI will pass this on. Believe me when I say that he will try almost anything.......He indicated that it seems to be coming from around the front of the rocker cover.... It is strange that it moves up the rev range when extra tension is placed on the timing chain though....

They send noises in all sorts of weird places. The only other noise that springs to mind that sounds similar is an Unhappy pump, but since you have tried it without the belt it rules out the PS and Water pump......what mods have been done to the Oil pump? 1 Link to comment https://www.fordxr6turbo.com/forum/topic/91160-desperately-need-help-new-built-engine-with-strange-sound/page/3/#findComment-1562158 Share on other sites More sharing options...

Seen the motor a few months back while I was getting oil for mine. Really hope he can get it sorted ASAP and with no warranty I don't blame him being paranoid about it. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/91160-desperately-need-help-new-built-engine-with-strange-sound/page/3/#findComment-1562160 Share on other sites More sharing options...

Quote what mods have been done to the Oil pump? It's dry sumped. from memory it is a Peterson.

The videos sound's not the best but it sounds like a hydraulic (ie oil pump) buzz to me. 2 Link to comment https://www.fordxr6turbo.com/forum/topic/91160-desperately-need-help-new-built-engine-with-strange-sound/page/3/#findComment-1562162 Share on other sites More sharing options...

There seems to be a resonance at that RPM that amplify noises. For us it ended up being exhaust related , but took ages to diagnoses as it definitely appeared to be coming from the engine. SO this noise may NOT be actually coming from the engine. Noise travels strangely through different components and metals.Very hard to diagnose from the short video.Sorry, I missed your post. Great input!! Thanks....
