no ideas bummer

 

Your best bet is to take it to your dealer.

 

i had the same problem here today in new york. I started up my car and it sound like the fan was hitting something. I dunno what it was but i'm bring my car in this weekend to the dealership

 

lifter noise. Try using a one step lower viscosity oil in the colder months. And use synthetic if you aren't already. Mine will do the same thing from time to time, early in the mourning, if I use 10w-30 in cooler weather.

 

the noise you are hearing is the VTC cams that just don't get the oil pressure they need immediately. Especially when the vehicle has been sitting and the oil has had time to drain out. This should only be for about 1 sec. anything longer and you may want to get the dealer to look at it. I know there was a TSB for this particular issue.

I know this is a different issue but I also hear a different sound, like when cranking at startup, and the torque converter is spinning up, I hear like a rattle/engagement very suddenly and withing 1-2 seconds of startup. Any ideas? Its not a serious issue I am sure but kinda annoying and makes the car feel cheap. I have 38k on my 2002 auto gle by the way.

 

yea...i`m about to switch to synthetic this oil change.....i figure that if it's going to continue i`ll just take to the dealer

thanks for the input
