Extreme Crankcase Vacuum: Yes or No?
I took off the oil cap on my mid 70's 454 while it was running yesterday and there was a huge amount of vacuum. When it's not running the cap comes off easily off but when running there is so much vacuum the cap or PCV is hard to get off, is this normal? I'm leaning towards no, what causes this?
