Quick brief about me, fellow grand prix owners.
My name is Timmy, I am a student in the Automotive Technology class, each and everyday I learn something knew, I am still a very inexperience tech but I do try my hardest. I am currently looking for a job so until then I am dependent on my mother. My mother bought me a used 2002 Pontiac Grand Prix SE V6 3.1L engine. I have a concern but the reason I haven't asked my instructor for advice is because he wants us to learn how to look up information and do research to find what we need to know. I have done some reasearch on my own but I'm still doing more and I would like you all or some to help. Your assistance is very appreciated and many thanks.
On July 31, 2012 at school I had changed my oil at 112,086 miles. I only had enough money from what my mother gave me to buy the Gastrol GTX High Mileage Oil with the Purolator PureOne oil filter special that Advance Auto Parts had. The oil is 5W-30 and before I changed it the engine was silent. After I changed it I started to hear a noice coming from inside the engine. The specs are 4.5 qts of oil and I put that, I looked on AllData to check out what cause these symptoms. The symptoms that I am hearing is like a rattle/tapping/knocking when engine cranks up cold. First it asks if the oil filter has an anti-drainback feature and it does. Next it ask if it has the correct oil viscosity, it does. Then it ask if the crankshaft thrust bearing is worn, this I do not know how to check. Finally, it says "High valve lifter leak down rate", not sure how to check that. Those last two I am currently looking up how to check those but if a heavier weighted oil was used how can you tell which one? Will using a heavier oil make the noise stop? Will problems occur is noise persist? Should I change the oil brand and put a different brand? Should I use oil additives such as Mystery Marvel oil?
Please again any help would be nice, any questions for me feel free to ask, again I am still doing my part to find out more.
