A "catch" can is supposed to collect excess oil from the crankcase-that is it's function. Fuel on the other hand, should not be showing up in your catch can. The only time I ever saw lots of fuel in the crankcase was on a car with a bad ECU. The ECU was holding the injectors open all of the time and keeping the fuel pump running constantly. That car did not run.

Best way to kill an engine.

 

Are the JE's 81.5mm also?

I had to ask.

A Catch can is supposed to collect blowby vapors, which is air/fuel mixture that pushes past the rings and mixes with the oil cloud.

You should be getting a oil/fuel milkly brown mixture in the catch can.

 

sounds good to me! hey read my signature! LOL

 

The ecu is good.. and yes the pistons are 81.5 all so..

 

anyone else??

 

well me and my boy did a leak down test and it had %10-%15 leak down in each one we also did a compression test and it came out like this.. 1 had 190.. 2 had 210.. 3 had 200 and 4 had 207... what do you guys think?? when i frist got the car done it was 255 across the bored

Blowby and raw fuel are two different things. As far as the results of the compression and leakdown tests-looks like it's time for the head to come off, perhaps a complete teardown

 

i just got the car back mybe 2 months ago it was fully rebuilt i dont understand why this would happen and i will tear it down if it has 2 be done but i want 2 know what u guys think befor i tear it down and its something stupit and could have been fited without do that.. im just trying 2 fit it without have 2 do that you guys know what i mean.

 

Alrite so i think its my rings we droped a lil bit of oil after doing the com. test and it went up so yea thanks everyone that tryed helping thats alot..

 

^^ did you make sure that the motor was warm because your pistons are forged and they need to expand

when you add oil it will obviously boost the comp. numbers because you are adding mass to the cylinder which makes less space which means more compression...

the only way i see the gas getting there is obviously if the motor isn't burning it all (get the car tunned) and because of poor valve seals and while combustions occurs maybe it forces the unburnt fuel to the head...just a clue, never said i was possitive

 

thanks alot i got new rings there goin in tomorrow when i get the block back from the shop.. thanks everyone who helped me im getting the car turned this weekend thanks

 

Sounds like a tuning/break in issue.

 

i had fuel in my catch can after i put in my non vtec cams and was running stupid amounts of extra fuel at idle untill i got it tuned so it would even hold an idle. it wasnt untill i got it dyno tuned that i stopped smelling gas in the car at idle.

 

bingo!!!! you win the dread.
also what kinda ccatch can set- up are you using. becasue u have seen problems with too much oil entering the catch can from a endyn set-up with out siphon tubes on the back of the block. the furl on the other hand if the compression numbers are good are more than likly your a/f ratio is too rich. and its spraying down the cylinder walls and not being burn during cumbustion. this will cause the cylinder walls to sctach and the rings to go. and dilute the oil
