I checked my compression the other day, on my CRVtec, and it ran 155 all the way around. It has stock bottom end, and stock b16 head.

What could be the problem? I also have a bad headgasket.... or something wrong with the head leaking. I could use any help please!

 

on my stock 10.2 cr b16 i got 170 all across
a b20 b with a b16 head is 9.0 cr
a b20z with a b16 head is 9.9 cr
so youe number dont lok to bad to me

 

ya I know.... but I was told it should be around 190 across.

if you have b20b....155 is a fine number!!

 

You positive? Because I heard different from a friend of mine.

 

Anyone else that has a CRVtec, that has done a compression test? Or know if 155 is a good number?

 

my numbers are all fuct up 190 150 160 170. what should i trouble shoot 1st?

 

Well 1st off don't hijack my thread, go and please make your own.

2nd off, those numbers are crazy...i agree on that.

 

Jason-

I think stock B16A's do 210 compression, so 190 would be a bit high. I'd say to do some compression checks on other people's cars, like someone with an LS motor to see where they are at.

 

Will do jeff. Thanx.

 

My friends b20b vtec did 180 with an untouched bottom end and head. However, different compression testors read differently. As long as your numbers were consistant (150 across all 4 cylinders) than you are fine.

 

Well that sounds good for the most part. I will re-check my compression again once I get time to fix my headgasket because that could make it that much lower, if there is a leak in the head. Thank you everyone for your help.
