Hello,

The loud knock on the top end of the engine can be due to low oil pressure on the engine.
Low oil pressure can be due to low oil in the engine.
So check the oil level and verify it is correct.

You can also have low oil pressure due to a faulty oil pump, it can also happen if the oil pump pickup tube becomes loose and unable to pickup oil.
This vehicle should have 35-65 PSI of oil pressure at 2,000 RPMs.

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
