High idle and no engine temp

[Yakozan]

refitted turbo and manifold today because the manifold to turbo gasket was exchanged.

Fired the engine up and everything seemed to be OK.
After I while a started to wonder why my idle wouldn't get any lower (stuck at about 1500rpm).

Checked my oil temp gauge which was reading about 65 degrees C and rising
My water temp gauge (Think it gets signal from the ECU) showed around the 55-65 degree C mark (don't remember exactly).

Checked the stock engine temp gauge which was still at the bottom

I was going to take the car out for a test-run but a so called garage mate had decided to leave his car in the middle of the garage jacked up and with no front suspension on Blocking the only way out for all the cars in the garage :furious:

That car will be removed one way or the other tomorrow :wave:

What can I do about this problem.
Have I forgotten anything when replacing the gasket?

I was thinking about disconnecting the battery and letting the ECU reset and make another attempt. Any more ideas?

Help me get my S15 on the streets again :thumbs:

Have you replaced the hard pipes with braided? If not, is the oil feed OK?

I've got braided lines :thumbs:
Problem was solved by topping up coolant and when doing so undo the air relief screw

Runs like a dream now. And so much quiter without the leak from the turbo gasket
Boost comes on much earlier. Now I only have to reset the EBC. Running in off mode now and that is no fun :yawn: (0.5Bar)

Thanks anyway :thumbs:
