Motor:

B18C 84mm 9:1.

Results:

#1: 110
#2: 110
#3: 100
#4: 120.

Car runs fine. Valves are loud, and need to be adjusted. Gas sucks. less than 200 miles a tank.

why low #'s?

 

its a little odd that all your numbers are so low, are you sure you conducted the test correctly?

 

Thats what i was thinking also. Engine has to be warm due to expantion,take out all plugs first,open up throttle plate 100%,5 cranks,make shure batt has full charge or hook it up to a charger.

 

what should the compression be at for a healthy b18c1?

 

200-210

 

pull the fuse for the fuel pump too

ill try that.

I took one plug out one at a time and did the test. would that matter?

 

when i do mine, i pull them all out.
it also depends if your car is warm or not
and if your pusshing the gas pedal all the way down

i push pedall all the way down, (after the car has been driven a little)
then crank few times.

 

wow, thats no good, sounds too low....

 

car was warm and been driven for awhile. pedal was all the way down.
