h22 compression is not right

[kispirit17]

ok today i checked my H's compression and 2 cylinders had 210 and the other 2 had 260 and i checked them 3 times and i got the same readings. i took off all the spark plugs and disconnected the fuel pump and ecu fuses to do the test and i had the gas pedal held all the way down when i was cranking ! why am i gettin these readings is there something wrong or is that good and no there is no oil leaking into the cylinders to throw off the reading. can someone please help

[kispirit17]

can anybody help

[cb7-tcakes]

should be even in all, which cylinders are reading the 210 and the 260?

[CB7Man]

If two opposites are the ones with 210 (such as 1 and 4 or 2 and 3)
The engine wont be that bad
But that is odd...try useing a thicker oil
Unless you want to tear it apart and replace compression rings

Those are good numbers. However the two lower ones are the ones to be concerned about. Now the previous poster said if they are opposite as in 1 and 4 cylinder have the low readings then i would do a leakdown test to insure backup. However it could be your rings (more than likely) or valve seals. But if it is on cylinder 2 and 3 i would almost say it could be your head gasket.

Real talk

i read somewhere h22 compression should be alround 250-275 i wonder if he"s rings are going out ? what you think guys iam not sure if my number are rite i read it years back ..

[wherm]

did you let the engine warm up to operating temp before checking compression?

[wed3k]

we need to know which two cylinders. it could be a blown headgasket if it is the middle two.

no way thats to much. all the ones that ive help joser, d112crzy tested about 230 and lower.

[kispirit17]

cylinders 4 and 3 are 260 and 1 and 2 are 210

[kispirit17]

and yes the car was warm when i did the test and i use mobile 1 full synthetic 10 w 30 high milage and there is no signs of head gasket damage

[accordztech]

do a leak down test to see if its just the valves.

What made you want to do a compression test ne ways?

[93.4dr.22A1]

and there is no signs of head gasket damage

loss of compression is a sign of head gasket "damage". Head gasket goin out just a tiny bit, between 1 and 2 could cause this. You dont always have to have water in oil, vice versa. And a head gasket is the easiest fix IMO

lots of things can cause loss of compression not just a blown head gasket. like rings or a bent valve.

[H23CB7]

yes you are correct there are like 7 or 8 different things that could be the problem. But almost always when 2 different cylinders are down in compression right next to each other it almost always points to a headgasket problem wether the car is smoking or oil in the antifreeze or vise versa. Yes we could be wrong and its just the rings but next to each other its usually a headgasket.
