69, sorry, I was busy last night and only on for a second whenI got home. Yes. You will almost always hear a very slight amount of air, not always from the engine but rather the fittings on the gage set. In any event, 25% is bad. (even for Indy...) The good news is you know why, and overall, it's not a catastrophic failure. The bill will be in the hundreds, plus a little time. That's not terrible.
