Message Hey guys,

I have a 1990 NA with 121,000 miles. I just did the 120K service (Finished on July 3rd). About 2 days after that, I find a coolant leak while driving. I could smell the coolant because it was dripping (one drip every 6-8 seconds) onto the driver's side exhaust manifold. I got it home, waited for it to cool off, and checked coolant level. It was not too much lower, maybe a quarter inch. I went for a 5 mile drive (about the same distance I went before I smelled the coolant the first time) to see if I could ID the leak, but there was none. SO, I pulled the plenum and am now at a dead end because I still can't fins the source of the leak. It's gotta be one of the coolant lines under the plenum on the driver's side, but I can't tell which one.
