I think those were the numbers. What are the suppost to read for a complete stock engine? Like what does honda say when the car is first made. is this good or bad.

 

What motor? Those look like healthy numbers though.

 

Its for a stock 92 civic. I believe its a D15B7?...

 

What are perfect numbers,what are healthy numbers, and what are bad numbers?

 

bump

 

anything above 135psi and with less then 28psi spread between any of the cylinders is acceptable

 

x2 the max I believe in the haynes manual should be 270 but like hotrod said there can be a difference of up to 28 psi per cylinder is acceptable.

 

damn 270 ? sounds a bit high to me

 

Yeah 270 seems high as **** for a completely stock motor.

I guess over the corse of 16 years and 93k miles the compression has lowered.

Im just asking this question because My car was overheating like crazy during idle sometimes but never on the highway. I have changed the thermo, cap....just recently changed the timing belt and waterpump and everything has been fine so far just wanted any heads up because people were saying it could be the head gasket.

Now the guy who did my timing belt said everything should be fine, but I plan on having this car for a loong time.

 

Oops my bad i thought you had a dohc 270 is for a stock gsr and Type-R stock sohc single is 184 at max pressure minimum is 134.

 

my sohc was 190 across

 

My Type R comp tested at 220 across the board. 270 is pretty [freak]ing high.

 

its in the standard haynes manual if you want ill scan it for you so you can see it

 

As long as my motor isn't low then I don't really care. I just dont see how there would be a 50-psi variation like that. My CR is already pretty high.

 

im not sure i guess when its a fresh motor ith evrything new its just that high i guess?? the lowest is 130 so your great where your at

 

my rebuilt y7/y8 is 210 across. heah was milled abit.

 

good info guys. I just had to re clamp my spark plug wires because the car was starting rough.

I finally have everything done to my car that I think I need done at this point.

 

you guys SOHC 190 and 210 thats great! for a single my gsr was jacked up 150 all across but i had 9-1 pistons in it because it was turbo but I needed new rings that I will have in a write up I'll be doing in about a month once i get my other project motor out of my garage.

 

This forum sure does give great information. Thanks guys.
