I know it's a stupid question to ask on the net where I can't actually hear it, but I have a 92 Caprice 305 with 308k on it, original timing chain and tranny as well.
The engine purrs like a kitten and doesn't burn any oil but I am getting this "rattling" sound after the engine warms up and the car is idling in PARK. If I step on the gas a little or shift to drive/reverse the rattling goes away. Actually it kind of sounds like it is coming from the tranny but it's difficult to isolate.
I am going to change the timing chain, water pump this week but I was curious if anyone had any ideas?
Like I said car runs fine except for that.
I was wondering if the screen in the tranny might be semi clogged and at idle there is not enough pressure to pump the fluid? I have NEVER changed the fluid and it is still bright pink and doesn't smell at all.
Any ideas?
