i upgraded my cams yesterday to 272 duration and 9.3 lift for both intake and exhaust. i noticed that my engine became so noisy. it's like someone's working on a typewriter.
my mechanic said that it's natural because i used stock valve springs. my tappets, according to him, is also within specs so i don't need to worry. after driving so long, i also noticed that my oil pressure is almost zero. my sensor connection is okay and when i rev the engine, the reading goes up also. again, according to my mechanic, it is natural for the oil pressure to go lower than usual when you upgrade cams and the reason why i am probably getting a very low reading is that my gauge may not be very accurate. btw, the brand of my gauge is autogage and my cams is Jun. please enlighten me on this. i plan to go to the dyno shop on monday and i'm not sure if this already okay. thanks guys. |

a whole lot of stuff, best to check the repair manual in the NA sticky thread, to see what you need to do.
any chance of going back to the person who installed the cams and get them to fix it, or taking it somewhere else?? -------------------- |
