wierd noise before TVIS
Wed, 23 March 2005 02:10
Need some help guys.
i own a 4age and it pings a bit during the normal rev range(1k-4k), there is a flat spot on 3.2k which i aint too worried about. i had pretty much given up on pushing the car above 4.5k due to the amount it pings below.
yest coming onto a freeway i thought i would kain it abit and see how much it is pinging(u can hear it really well, as the noise bounces off the sound proof barrier). to my suprise it make a really wierd tapping sound from 3.8 to 4.5 and then when tvis came in the sound went away and the car was pinging less then before!!!!!
WTF was that wierd noise... i kno the exhaust manifold has a leak, but i dont think thats it cos it only makes that noise from 3.8-4.5(and it gets louder as it gets closer to tvis). the engine has done 255000kms so i guess it could b a worn lobe on the cam.
also, can i disable the 'thing' that stops second set of intake vavles from being used below 4.5k and it is at all feasable? will i lose ALOT of torque and increase consumption?? has anybody done this before?
do you think that would fix mt tapping noise.
