VR Buick 3800 compression test?

[Bizmark]

Had a compression test done on my V6 VR early this year and these are the results, I think it was a dry test?
Cyl Comp (psi)
1: 130
2: 140
3: 140
4: 140
5: 135
6: 140

Had about 265xxx k's on it at the time, does the above indicate a healthy motor or does it look like trouble?

looks pretty good mate, for a motor that has 265xxx kms

 

[F l a k]

Sounds healthy to me, does sound good for the k's.

Old thread but does anyone know what the compression figures would be on a low km engine.
I have figures from 140 - 155 VR Buick. But i have no idea if this is as good as the mech says they are.

If I recall correctly it would be around 165psi with 99 being the minimum allowable figure which is really poor in my opinion.

We do 150 - 155psi with a cam in an s1 buick which is lower comp than vr .140-150 is still healthy give or take some gauge variance and cranking speed .

Thanks Delco and VS, sounds like mine is fairly decent.

Can be massive variations in pressures between gauges too. Some are 20-30psi different. But at the end of the day you’re more looking for consistency than anything else so pinpoint accuracy isn’t as important as repeatability.

My little old VN averaged over 180psi per cylinder
