Noise After Cams Upgrade Options

[fgvillegas]

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.

i went to my tuner today to have a second opinion. according to him, the oil pressure is okay. the sound that i hear also are the tappets but it's just okay because it is usually in the loose side of the specs. sound of a very loose tappets is different.

with that said, i decided to go on with the dyno tune. he's a very good tuner here in our location and i'm happy with the result.

now my worries are gone and what i have now is a big smile on my face.

thanks guys for your input and suggestions. i really appreciate it a lot!
