SRX compression


It depends highly on the compression tester being used. It is more imporatant that the numbers you get for each cylinder are VERY similar, no more than a few pounds difference. Leak down tells you a lot more about an engine.
 
^ i agree..

i got, p140 ,c135, m135 on my '01, if that gauge is right i'd say
your down a little, but like holic said a leak dowm will tell the truth..
 
My 00 with 10,000 Miles had 132 132 130 when I refreshed it. I have only put 100 miles on since then. I check it out tomorrow and see what it improoved.
 
A cheap gauge will always be off. I tested my sled (01 srx) 1st gauge said 135-136 and 2nd gauge said 120 on all 3. As long as they are within 5-10 percent of one another and not toooooooo low you should be ok. Flat up top.....powervalve issue??? I had a bad wire cap and fouled #1 plug and it wouldn't go over 80!!!!!
 
I had a cheap 30 dollar analog one I picked up. It read 130's across. I picked up a sweet digital one for 180.00 and got the 132 132 130 readings.
 
my 99 srx 700 has 120-120-120 with 7800km on it. i have a cheap tester that i paid $39.99 . i would also think you are fine as long as all your readings are within 10% of each other.

Some would say yes,,it's cheap and easy to do,really don't need to
hone eather..

like said earlier do a leak down...
 
well i got 100 across on a cold engine then 120 across on the cold engine. runs like a champ, but should i do rings this summer? i want to just so i know i have good compression. my 98 srx has over 8800 on it now. riding this morning at 10:00.
