Loud engine knock beginning at 1200 rpm
This is my first post. Just bought . 2000 Boxster with IMS issues.I just finished the replacement. At start up no issues. Test drive no issue until 1500 rpm.then a knock. Under this rpm nothing, over a knock.
This is coming from the bottom of the motor. Increases as rpm increases. Called the past owner he said that when he removed the oil pan he found lots of metal. He believed it was the IMS bearing. It may not have been all the issues.
Any insights
