Losing coolant every few weeks. Trying to diagnose.
Pressure tested it today and it held 15psi for most of the afternoon. No visible leaking I can find.
Oil level hasn't risen and oil looks OK.
I had to drive it to take the garbage out so it's currently hot. Planning on taking the plugs out tonight once it cools down and pressurizing it again. Going to look at the plugs and listen for hissing and maybe drag out the bore camera to see if there's any coolant dripping in. Also plan on pulling the valve cover and checking for signs of cracking (believe it has the original head).
Also going to remove the lower engine cover to get a better look at the underside.
If you have any other suggestions while I have it partially apart, I'd sure appreciate them. I have a few other things to take care of so I planned on it being down for a coupla days.
