engine noise??

[rstb88]

go ahead and send me a pm on how to check and see if the mount is being rubbed. cause that'll give me a reason to look at the suspension as well.

im a diesel tech and im pretty sure the "dit-dit" or clicking noise u hear when u shut the car off is the thermostat in the engine poping in and out, cause once u shut the car off, everything is off, even the cooling system... so bsically the engine cooks itself, its alright no need for alarm, my dodge dakota, my chrysler cirrus, my girlfriend's '88 buick lesaber does it... to eliminate that sound... just dont pay attention. hope that helped

I hear the same noise too. I mentioned it to the tech when I went to the dealership for my first oil change about three months ago. Apparently nothing was done that time. May be I will mention it again when I go for the next oil change.
The strange thing is sometimes I hear it when I switch to the R gear, sometimes I don't.
Since nothing serious has developed, I am now ignoring it. I don't know if it is right to though.

The noise in reverce is annoying but normal and completely harmless

The cause it the exhaust and the way it's suspended under the car.
When the car is in forward or reverce it torques/twists the engine in one direction or the other. In forward the exhaust fits snug together, however in reverce they exhaust is being twisted againt it and a slight bit of rattling between the joints can be heard.
Don't worry about it, a lot of 4CYL/FWD cars do this
