just wondering if there is a way to rebuild compression in a motor. Because i have 115 psi in the back rotor and 50 in the front but the car runs great boost fine only thing it floods when try and start it.
and if i run it like this will it damage the motor??

You can't really fix this problem without taking the engine apart. Hard parts inside the combustion chamber need to be replaced.

50psi is the lowest I've ever heard of, but at worst you have an already done the damage to the front housing\rotor.

how in the hell?

I assume you have a bad oil injector and or lines.

Start premixing and see if anything changes. More than likely the engine is toast and needs a rebuild.

Thanks guy's i dont really get much responds on here other than this but how much do i premix,what kind of oil do i use. I try'd the atf but does that really break free seal's sometimes??

You could use atf but i prefer sea foam over that stuff. I would guess with that much difference between chambers you have either the leakiest fuel injector in the world up front or you have a bad oil injector.

Run 1 oz per every 2 gallons of gas. Maybe a little more.

so maybe its not my motor then??i have a fuel pump switch and i only can turn on the fuel pump for less than a sec and it flood's. Regular seafoam the luquid stuff right, how much do i put sorry didnt ever have to do this stuff before...

bad injector or lines??? his front rotor has no compression thats the problem, sorry dude your motor is basically toast. theres no way of fixing it without taring the entire motor apart and replacing things

that much

and also since theres still about half the normal compression at least you haven't blown an apex seal. if your engine isnt burning a ton of oil or coolant or something it still might be ok. I personally don't know what would be wrong with it, but it seems to me that this could be a fuel problem like others have suggested.

i meant how much seafoam should i dump in the chambers sorry not tryin to be a wise crack or anything but if anyone has info for sure on what this could be stuck seal maybe??please put input and thanks so much to the ones that have already

VacavilleFC

stuck seals? chipped seals? hmmm could be a number of things

O and its not loosing any coolant it burns oil but not to bad i dont think didnt run it long enogh or maybe it doesnt burn oil maybe it leaks a little but runs great other than flooding and really slow under 2000rpm
im only 17 guy's sorry if i dont know much yet.

im 18....
If it doesnt leak coolant (no excessive white smoke when the car is running) that mean ur coolant seal is still good
Burning oil is normal unless ur loosing 1qt of oil everytime u drive then u mite have oil seal problem
If u compression is low u most likely have a stuck apex seal or chipped.
Also did u get ur compression check when the car is fully warmed or wut?
Also does ur car hold idle
Prepare to save money n get a rebuild or reman

no coolant leaks no oil missing from when i changed it car was warm when i did it but idk if it was fully warmed up no white smoke is there a way to unstuck a stuck seal LoL and if i do rebuild can i just do the front since the back still has good compression?? any help will help alot! Hahah

VacavilleFC

your motors toast dude, it's gonna need a complete rebuild. jdm motors are garbage. i'm sorry you wasted your money

hey dude, vacavilleFC..
you said it yourself, it could be a number of reasons.
it COULD be the oil injector being bad/along with leaky injectors. i think i have somewhat of the same problem.
altho i'm premixing now.


do you have any background info on the car the engine was from?
it might be a rebuild that was sitting out (sounds like a reaal stretch but you never know)
maybe the engine needs to be worked in..
just get your injectors cleaned. and check your oil injectors.
hope you the best of luck, and rebuilding the engine isnt all THAT bad.
atleast you have a reason to take it apart and Port the engine now =D
