[QUOTE=great pumpkin] Thanks Joel, the car has been in winter storage since late October. Is there a way to check the rad.cap for pressure?

Soitanly!
Terry, there is a pressure tester for checking the rad caps, but I don't think it is capable of checking the suction aspect of the cap. If you are concerned about keeping the car original for later, go ahead and get a new cap, so you can at least drive the thing without having to worry about it. Then, when the time comes, say, you have it judged, or show it, just pop the original cap back on. Us NCRS guys do stuff like this all the time!
Some of the older, original caps just won't hold the pressure, and the car will puke...not a good thing when doing a PV(Performance Verification) test, or even the Operations check. So...on goes the newer, good cap for that, then swap for the original for judging.
Then again...your cap may have been defective to start with, and you just happened to notice it now. After sitting that long, there shouldn't have been any vacuum on the system anyway, so at least ya know there ain't no coolant leaks!
btw, John...that is NOT a cure-all for everything that ails yer car!
...it IS fun, tho, ain't it?
