Internal coolant leak
My 92 pickup, 22RE, 188k miles has an internal coolant leak.
Oil is clean (no antifreeze) antifreeze is being burned and going out exhaust.
I bought a Snapon cooling system tester on Ebay (very cool tool).
With engine off, pump to 10 PSI, drops very slowly.
With engine running, pump to 10 PSI, drops slowly (just a smidge faster then engine off).
Has the head gasket failed or have there been other failues (in block or head).
Thanks, Jerry

With the engine off, can you HEAR where it's leaking? You should be able to. Pull ALL the spark plugs & listen while the pressure drops, then turn the engine over & if there's a leak into the system, it will blow it out the offending plug hole.
