i did a compression test the other day with my car. From the right cylinder to left the results came out to be 155, 160, 155, 130. the 130psi kinda gets me worried. Is 130psi that bad? or is it still okay. need helpp! thanks

 

i would redo the test one more time and if the numbers are the same i would say its either head gasket or worn piston rings in left cylinder... u can check that by taking out a spark plug from a cylinder that got lowest numbers and put some oil into it. Then re do the compression test and if the numbers are higher then your piston rings are fried:/ good luck!!

 

how many rotations/secs did you do in each? looks like the 130 is kinda low

 

u should make as many rotations as u gave cylinders rite? for ex. 4 cyl.= 4 rotations and 6=6 right? just making sure i know the right way....

 

yes, other wise reading in each will be different.. the more rotations you make the more pressure you will get.. 4 rotations is about 180-190 psi

 

I redid the compression test with about a teaspoon of oil dropped into the cylinder and came out to be around 150psi. im just hoping it was just a bad test...

 

well i dont want to drop this down on you but it might b a really bad man... but i hope everything will b good.
