do I need to crank over engine after replacing turbos

Recommended Posts

I have just replaced my turbos, I'm just putting the last few bits together then fresh oil and water, my son just happened to mention "are you going to crank the engine over to get the oil around the turbos first before you start it up fully?".

 

My question is, is he right and if he is how is this achieved?

 

Cheers.

cheers Matt, thank god he came out and mentioned it or I would have put it all together and fired it up. Sorry my communication is slow I'm dashing up when I finnish each bit, is there any other things I should watch out for when I start to test them out?

I might be making this up, someone can either confirm or deny.

 

Is it not better to do the crank with the plugs out? So that there is no pressure in the cylinders?

 

One of my reasons for thinking this is it will have a lot less load on the starter.

You may have a point there as the engine should spin a bit faster and maybe stop the pressure going from the chamber spinning the turbo's?

But the guys on the GT4 owners club never take the plugs out as its a pita on some with charge coolers and never had any trouble.

 

Im not sure how easy it is to take the oil return off and check when the oil has passed through the turbo's?

 

Just let it idle for a few mins when you do come to start it.

And bob just keep and eye out for any leaks

As soon as the oil light is out you will have oil at the turbos.

Nice one Bob, not that bad to do after all ehh!!!

Well, once I sorted yet another problem, I used Matts method, it took a while for my water to sort its self out (think I had an air lock somewhere), everything good at the moment. Its just so scarey when you have done something like that then you come to the moment of trueth.

 

Anyway thanks for all your help.

 

Bob.
