Hey guys, I have a quick question for you. I recently noticed that my 91 Civic SI is burning some oil. I have replaced the PCV valve and that has not made a difference. So, I am going to do a compression and (maybe) leak down test. I was wondering if any of you could tell me what the stock compression should be on a new D16A6 with no modifications, just so I know approximately where I should be at.

Thanks

 

great condition 185psi
Lowest condition 135psi
difference between cylinders 28psi.

make sure you disconnect the coil on the dist, and you hold the throttle wide open. Do it with the motor hot.

 

Excellent. Thank you

:thumbup:

 

this is off topic but you had a celica alltrack or a custom celica turbo

 

1988 Alltrac. G-Force tested at 263 Hp. at ~14psi of boost.

 

lucky you what happend to it

 

I was rear ended by some old guy in a mini van, and it pushed the Celica under a Dodge 4x4 in front of me, and it was written off. What really pissed me off that the only damage to the van, was a headlight, grill, bumper cover and bumper. Damage to the Celica, both headlights, hood, grill, intercooler (truck had a hitch on it), rear bumper cover, rear bumper, both tail lights, and hatch.
