Re: Hard to find Coolant leak..
Thanks guys, does the T stat need to be open (engine warmed up) so the pressture test tool is inserting pressure in intake/heads/block?
Wiped head/block area and pumped back to 15 PSI and that seam is dry....one drop on floor pan and a drop on bottom of starter.
PSI bleeds down to about 6-8 after 15 min. IDK if the "seal" the tool is making is 100%. Its the cone "universal" compression fit
fitting in this kit as there is no dedicated, out of at least 20 caps, one that fits the old 2 slot radiator neck
The area behind starter (against block) is "moist" (oil/road grime but moist compared to rest of motor) which is where the rear freeze plug is. I will pull starter to get a clear visual.
My initial thought was the heater hose connection, or core, but (even after tighting the clamps some) that joint is bobe dry
IDK, but assume, it "weeps" during driving but there is a teaspoon or so (drops) from parking it on the pan I put under the car
This is the 327 original to the car, according to #'s, but at some point was rebuilt in its life. The forward freeze plug looks good...the rear one behind starter has crud built up in it. Will know more when I pull starter
should it be the plug, what size freeze plug for 327?
