GC8 type R sti oil issues

[creecha]

Hey guys, a shot in the dark until I get time to get it checked.

Scenario is this.

Got my top end rebuilt by macbilt in Wellington(yes will call him on monday).

I'm now in Auckland, did the drive up here no problems, taking it easy and running the engine in nicely. Its now up to 800kms.

A couple of days the check engine light comes on when the engine is cold and I'm idling, it happens as the idle drops from just over 1000rpm to about 6 or 700rpm. As I drive off it goes off. I had put 95 in for maybe half a tank as I was nowhere near 98 which is scaring me as well.

It's done this a few times now but everything sounds and runs normal.....until tonight.

So had just come off the motorway and I see a little bit of smoke coming out and the oil light comes when i pull up to the lights and engine starts to idle. I pull into where I was going which was very close by and shut her down and open the bonnet to see where its coming from. Its coming from down low on the left looking at the engine.

I check the oil and levels seem normal. Nothing had been dripping previously but now after leaving it for a few hours there were a couple of drips under the car.

I eventually had to go home so again checked the oil and its still good so I drove home and of course get every f*#%INg light. As I pull up of course the oil light comes on as I stop at the light, and a small amount of smoke comes from the engine again, if i rev the car below the idle the light goes off. I make it home ok, there is a little bit of a burnt oil smell but the car was behaving normal. The oil light came on when left to idle but as soon as a small amount more revs are given it goes off. As well as this the check engine light came on but went off too.

Anyways its a stab in the dark but this is the story so far. My non mechanic brain thought it could be something to do with the oil pump not getting enough pressure but to be honest I don't know ****.

If you feel like speculating please feel free, if you know any good not too expensive shops or just cool mechanics in Auckland who might be able to check it out, plug in a laptop and see whats been going on by all means message me.

Cheers

Do a manual CEL/diagnostic check to see what CEL came up. By connecting the 2xsingle black read plugs, straight above the clutch pedal:

List of CEL codes also here:

The oil light is concerning, how many kms has the block done? Leak could likely be the rocker gaskets or turbo oil feed/return.

Apparently the block was replaced with a reconditioned one appx 100,000km ago.

I just had the block stripped and honed, new bearings and rings, valve grind on a new second hand head, new waterpump and cambelt kits, new clutch and spigot bearing. Alistair said it has 1.5thou ovality in the bores.

The errors the diagnostic check said were 22-Knock Sensor and 21-Engine Coolant Temperature Sensor, it ordered them like that 22 then 21.

sounds to me like oil pump has shat itself, either that or the o-ring. rare thing for al's work to have a problem

[creecha]

yeah I know, and if I was in wellington I'm sure he'd take care of me but alas I'm not. I'm pretty sure I've kept within his running it in guidelines as well. I'll talk to him tomorrow anyways.
