Update: Coolant has been disappearing –over the course of 3k miles it will drop to the bottom of the overflow tank instead of being at the cold line (when cold). I first noticed this in Feb. Topped it off in Feb, then in April (3k miles), and now again in June (another 3k miles).
While checking for vacuum leaks due to the intermittent stuttering idle, I noticed a puddle at the base of the front passenger side of the manifold. BTW – my manifold cover has a date of ’01 stamped on it. My car is an ’00.
Can’t see the leak here… but it’* located on the left (passenger) side just below the spark plug wires.
At the base of the manifold cover, there’* coolant collecting in the valleys where the bolts are.
This is a pic farther to the right (towards driver side) …although not currently wet, you can see signs of contamination… the far right side is dry/clean.
Inspection of the oil cap shows no signs of contamination….yet
Technical Ted stopped by today and check the coils - cleaned and dielectrical greased them; replaced the air filter (wasn't too dirty...but changed anyhow since it was apart.) Started up the car...ran for about a minute or so... something made a funny noise (like a fan stopped or something)...then the chuggling (rough idle) began. Reved up the RPM'* to 1500...chuggle still present. Don't notice it when driving, however backing into garage it could be felt.
Message left for Dr. Boosty... I wonder if he makes house calls? I wonder if I can make it out 400 miles to Bonnevilla?
EDIT: Here'* how I know it'* coolant...actually looks like some oil too. Stuffed a Bounty papertowel in there to soak up the puddle...oil with definite orange (Dexcool).
