I recently overhauled my 12HT engine and I think there is excessive noise. Whenever I am on high RPM on low gear I felt something is hitting inside the engine somewhat fast like ‘tak-tak-tak’ and then at the same time there is the normal sound of the diesel engine humming . My mechanic is a petrol engine expert and he and is pretty sure he has overhauled it correctly.

I wanted to know is there any way to determine through engine sound on the engine condition? Or is there any testing checklist to make sure on engine condition.

I recently went on long trip but had to return back as I noticed the engine oil was leaking through the filter and was worried incase if there was exceesive pressure built up? My mechanic is somewhat confused as new problems seemes to surface up and I thought I can provide him a checklist to make sure he verifies it and get potential issues sorted out incase if he has inadvertently goofed up.
