New turbo fitted, howto get oil to it on the first start up?

[Jonas_R]

Well,

I have changed my turbo and now iam going to change the oil to.

But do I need to do something to get oil into the turbo? Or can I just start the car up?

I dont want to break the turbo, I guess it uses the oil as a lubrican.

Is it not possible to pull the engine around by hand and thereby pumping oil through the system? I can't say for certain that it's possible, but that would be the first thing I'd consider.

[Jonas_R]

Yeah I guess that would be a good idea, would be kinda sucks to ruin the turbo.

Get someone to tow you around for a bit in 4th, 5th or 6th gear if you are that worried. I am sure it would be ok cold starting with a new turbo, I am sure someone here will give you a more precise answer.

I would have said if it is a new turbo it should have been built with some sort of lube for the first time that it is ran! Just a guess tho!

Surely hand cranking the engine won't give you the oil pressure you need to pump oil to the Turbo.

Unplug the Hallsender. Then normaly the engine will not start. Turn the key and let it turn the engine some seconds till you see oil pressure.

Ah yes that's right. I was thinking about when a friend was about to start his newly built engine for the first time, and I remembered it wrong. He did use the starter to pull the engine around without the ignition connected, so he got oil through the system. I should not give answers I'm not sure about anymore.

When i replaced my turbo, I unplugged the injectors, let it turn over for about 10s, of for 10s, turn over again... after the 3rd try the oil guage had built up to about 2-3bar oil pressure, figured this is enough.

You could even leave the oil return hose off the block and wait to see oil seeping through, if that would keep you mind at ease!

I like the idea of unplugging the fuel injectors.

Is there any problems with the plugs and no fuel?

Oil presure

Personally I would remove the spark plugs and remove the plugs from the ECU and crank the car over. With the plugs removed there will be little air passing the turbo vanes to rotate it and it will also turn the engine over faster as no compression to slow it down building up pressure quickly. Is a method normally applied to new engines on first start up.

un plug injectors and remove plugs, that way the engine spins much faster as the pistons are not having to work at compressing the air.

All you need to do is disconnect the hall sender remove the spark plugs
Leave the oil feed hose to the turbo disconnected if not done already put a clear plastic bag over the feed hose get some one to crank it over untill you see oil coming out of the pipe then fit the the pipe back onto the turbo now you know 100% that there is oil there in my experience you could have a blockage or any thing in that feed hose so its best to check you have good oil flow threw there otherwise its bye bye turbo pretty quick thats the way i have been taught to do it

Do I need to remove the sparks plugs or can I just unplug the ignition cables going to the spark plugs?

BaltiboyS2:
Is the oil feed line located on the top or on the bottom of the turbo?

Where can I find the Hall-sender on the 3B coupe?

As I read the advice.... remove the plugs, as this will mean the engine spins quicker as the pistons are not trying to compress the air...
