When it comes to compression, i know that in general, the numbers in a common chamber are all usually within 5psi of each other(unless you have broken apex seals) But are there any parameters on what the numbers should be in reference to seperate chambers? And if so what could this indicate? What i mean is what if the compression numbers look something like 9.0/9.3/9.3 @250 in the first chamber, and 7.6/7.8/8.0 @250 in the second chamber. Dont know if it makes a difference or not but the motor is greddy boosted w/ AT secondary injectors. Compression was checked at mazda, me and my friend that is a tech there did it. (Oh yeah my guys at mazda know their stuff and have been really good at helping me out on the low since im a salesman there.) All thats besides the point...any body got any info on how to answer my question?
p.s.- u can get a close psi number by multiplying the number from mazda by 14.2
example= 7.0X14.2= 99.4psi
(im tryna keep from getting hammered by u tough forum vets!)

 

yeah a variance of more than "X" from front to back is a sign of side seal failure. meh i think its side seal. im tired.

i dont remember the X but since your freind is the TECH he should be able to look it up really easily

check your pm's please

 

interesting.

i might have a question or two for you!!

might need you help on two levels!

btw, still nice to see you around. baby sleeping better?
