there is no oil going to the top of the motor would that be the oil pump

Not sure how you would know there is not oil getting to the top of the engine. I'm guess your hearing top end noise. Timing chain on that vehicle can make a lot of noise if proper maintenance was not performed ie: oil changes every 3,000 miles. The chain may be loose due to worn guides. Also, oil passages could be clogged, oil pump pick up tube screen could be clogged.
