Hi guys, trying to diagnose litres of oil that has poured out of the drivers side of the engine under the plenum and im having troubles removing it.

post-20826-1175930821.jpg

I have removed all the injectors, bolts to the block, fuel rails, and hoses at the rear of the plenum, but having no luck getting the AAC off.

have photo attached

got one of the bolts off, but is there and easier way? i can wiggle the plenum assembly around off the block, but cannot remove it as it wont come out far, can only assume its just the AAC still attached causing this.

Prior to all the belts coming off the car was making a weird whiring noise, i got the power steer unit overhauled, and have just inspected the belt which seamed in great shape for 90,000kms, and the idlers and pulleys seamed healthy too

i did notice the pulley on the aircon unit has a little bit of play in it unlike all the other pulleys, when spun freely it makes a grinding noise, how hard is it going to be to fix this? and will i need to dump the gas?

thanks for the help guys, once this is sorted, hicas and the massive ammount of grease i found under the front left steering rack i can maybe get the car i purchased from a dealer interstate on the road!

Do you know what your doing!!! Whats pulling the plenum off going to do...

I'd say take it to a workshop before you do something you can't fix.

You should have looked for cracked lines, blown gaskets, disattached hoses etc. before randomly pulling the plenum off.

if you have a huge oil leak under the plenum then i'd be looking straight at the oil filter and oil cooler assembly...

what your doing looks like a real mess.. have you jacked the car up to see what things look like from underneath?

i have claustrophobia so have problems going under the car,

i am deffinate it is the oil cooler and filter assembly i just need to get at it from the top side down, the plenum is just a pain too get too

BAMR33 - i have already checked hoses, gaskets etc. i know where the problem is, getting too it is the problem thanks

Take a deep breath and face your fears. :laugh:

DO IT DO IT DO IT!

im thinking of buying some wheel ramps, im really unimpressed with the idea of going under though, i already had a blast getting the sump drain bolt out

Yes ramps are good but for the general stuff I prefer axle stands + chocks under the front wheels + the wheels under the car also. Rock solid, doesn't move, absolutely no chance of being squished.

went top side in, too much oil under but the exciting news is it looks like its coming from everywhere, almost an engine out job!

great news is my car has been raced before, the lockwire on some components is evident too this.

thanks to the useless roadworthy dicks who said my car looked good and my mechanic who assured me it was probably just driven hard on the road

Thats a busted coolant hose?

Where's the oil coming from?

i cut that hose myself, replacing it as it is f**ked and for lack of better words glued to the block

not sure on coil, there looks like a breather on the tranny is loose though, going to call a friend over to look over it today

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
