a cookie to whomever explains this........

ive got a ka24de. the motor runs fine, but uses oil... it leaves none on the ground so i assume its getting in the cylinder. i did a compression test and it came up with 120psi all the way across all 4. isnt it supposed to be more like 170? and how in the heck did i lose the exact same amount of compression across all 4 cyls? the car does smoke a lil when you rev on it, but nothing too terribly horrible. pulled the codes and there are none. so whats goin on???

[neverlift]

take your pick... either rings or valves are pwncaekt.where the fug is my cookie

[neverlift]

btw yeah around 160~170psi is good.120 is very very very bad. Add oil in the spark plug hole and see if it gets better(higher) if it does your rings are what is bad. best of luck

[7spokenightmare]

if that were true, wouldnt i see diffrent compression on all the cyls? i mean how likely is it that all my ring or valves (or combo thereof) failed in a manner to create the same values across all 4 cyls?

why are you starting new threads about this? sounds like your motor is thrashed, you can either rebuild it or swap in a new one.

there's not really much to gain from discovering what happened to make it that way; or its not very cost-effective to do so anyways.

start looking at getting a new motor.

i dont believe the motor is "thrashed". it runs fine... just smokes a lil at high rev. dont see any real power loss out of it... im just getting weird crap as i try to look into it.

i was hoping maybe there was an explanation such as timing or a ka specific issue that would explain it.

maybe i checked the compression wrong? heck i dont know.

i have a hard time believing that my motor is trash when it runs fine and has no real issues while im drivin it.

the reason im using multiple threads is because i cant seem to get anyone to respond... either everyone here has no clue (hard to believe) or i must be asking the wrong questions

[dickie]

im willing to believe that you performed the compression test incorrectly, but then again i could also go for the theory that you have a tired motor from your description of the symptoms.

it smokes and bad compression is a dead giveaway for bad rings causing blow-by.

Steps on dong this correctly1) Run the motor for about 5 mins or so untill it is warm.2) Turn it off3) Unplug the fuel pump fuse and open up your gas tank cap4) Start the car untill it dies completely5) Disconenct The plug on the distributor or Unplug your ignition coil6) Install compression gauge at #1 cylinder7) Crank motor for about 8-10 seconds while holding the gas pedal down with your foot.8)record numbers (helps to have a second person, but can easily be done by yourself)9)repeat steps 6-8 for each cylinder

DId you do exactly this?

stfu d!ck I said that already

I'm willing to bet your **** is down on power if you got 120 across the board.

ok typically, if ALL are down an equal amount its your rings are bad,and if they go up/down randomly its your valves OR an pwnt head gasket. Seeing yours are all down equally your engine is just old and worn out like a lot lizzard my sohc went 145/155/160/140 or some shyt. The dohc wont get it. she will recieve her turbo and stfu untill death

i know you said it before, and so did a couple other people. i dont know why its not sinking in...

I would say it has sunk in for people. I just put down the steps so that in the small chance he did it wrong he would know. 120 across the board....thats major power loss from a healthy motor.

[neverlift]

clearly it is not down on power you heard dood its still making 200 whp lol.

I think he is mistaken a maf system(that is constantly monitoring and adjusting afr) compensating,for the less comp. And yeah it will feel like the power is the "same",but trust me its not,go drive a 240 with only 20psi more sacross the board. YOu will feel it.try some restore

ok - so i went back and checked the compression the right way. i was using my remotestart to crank it before and it apparently didnt crank it enough. now i have 180 all the way across. compresson checks out.

i did notice that im getting lil plumes of smoke out the plug holes, but this time all the holes either had spark plug or compression tester in them... it isnt coming from the plug hole itself.... but down inside that opening somewhere.

again... my issue is that the car is using oil, but none is on the ground underneath it. it is def losing it thru a cyl... is there any way to test valve seals?

Look here "dood" he did it wrong the first time like I had thought.
