Is it true you can tell the health of your compression but the vacuum reading? I read that as your compression gets worse your vacuum reading will get closer to 0. So for example, a -10.5 would be a really healthy motor while a -9 means your compresssion isn’t as good (please note the reading must be taken when the car is warm with the air off. ’ot doing this will skew the reading)
While we are on the topic, post your idle vacuum reading from the accessport.
mine is between -10.4-10.6 for the most part.
