SR engine noise VIDEO
Hey guys. I need help figuring out what's wrong with my engine. I pulled off the valve cover today and looked @ the timing chain and guides and the complete valve train. Everything look OK as far as I could tell. No slack in the chain and the guides looked great. There is also a squeaking noise coming from the rear of the engine.
Red top sr. Stock cams. Been running great for the past 2 years. Installed a gt2871r, 740cc injectors, z32 mafs, Apexi PFC, walbro fuel pump all in January this year. Compression is 150 across. No vac/boost/exhaust leaks. I was driving pretty hard last weekend on the way up to a 240 meet with several other 240's. Noticed a high knock level once or twice on the PFC commander. Car ran fine the rest of the way there and back. Noise started about 2-3 days after. http://s3.photobucket.com/albums/y88...ginesounds.flv Last edited by awd2rwd; 06-03-2007 at 10:09 PM..
