Default Leak just under the PCV valve......

On the 95 Bonnie I just bought, there is a coolant leak, just below the PCV valve at a little elbow. The (edit UPPER) intake has been replaced, but it looks like it looks like a stock replacement. I dont' know if the lower has been replaced as well or not.


Anyhow, there'* a hard plastic elbow that comes out under the PCV valve, and takes a 90* turn and goes through the alternator bracket. I'm not sure where it goes from there.

What does that coolant do?

Turns out there was no o-ring in it! Dag-on....

I'll be changing the intake in the coming weeks just in case. I just don't have the time to do it right now.

Sheesh.
