Question
QUESTION: my oil pump want bad which cause a tapping sound under the hood i drove it for 30 miles do you think i mess anything up
ANSWER: Hi
It is possible. If the tap is a deep "throaty" knock, that would be a crank shaft related knock, which IS bad. If it is a light fast tapping coming from mainly the top of the engine, it is probally a valve or valve train related tapping which should be addressed, but is not as damaging as the knocking.  I would tell you to take it to a mechanic in your area that you trust, and have them check it out for sure. Sorry for being so vouge but I hope it helps.

Answer
Hi
My advise at this point would be to take vehicle to a mechanic in your area that you trust, and get them to check the engine out.
If you do not know an honest mechanic , most mechanics/ auto techs are honest (despite what people hear) and will generally give you an true estimate to protect themselves and their companies reputation. Ask friends/family.
