Hi guys.
Long time lurker, 1st time poster.
I've a 2008 Accord 2.2 CDTI sport GT tourer with engine code N22A1.
She has 145,000 miles with a very good but not conclusive service history.

So I've got the dreaded cloud of white smoke from a cold start. This is gone after a few seconds but if I then press the accelerator I get a follow up cloud of blue smoke. Blue smoke goes after another few seconds.
So am I correct to assume I've a cracked manifold causing the white smoke ?

I am then assuming I've a problem with valve stem oil seals giving me the blue smoke. My reason for thinking this is being that the blue smoke goes once whatever oil is in the cylinders burns off.

Any thoughts on this diagnosis or am I wrong ?

The car pulls well and is overall close to mint considering its 1p years old. I'd consider doing the valve stem oil seals. If however it's further down in the engine as in piston rings I'm wary of the massive bill...

Is it drinking oil? does it blank out the following traffic? if not then stop worrying. Change your oil at 6,000 and a new filter at 12,000.

More likely worn turbo seals on this engine I would say. How much oil does it use?

Drinking oil, no.
Burning some oil yes.
I serviced it 2 weeks ago. Oil and filter.
I keep a really close eye on the oil level.

Car was last serviced late December 2017 and since then has done about 4 thousand miles.
Used approx a pint or slightly more of oil in topping up between services.
Once the car has ran up to normal temperature all smoke, white and blue disappears.

If it's only the turbo seals id be a very happy man as I can deal with all those issues myself.

So since I've posted nothing has really changed. Same issues.
Can anyone recommend a parts supplier that delivers to Ireland where I can source the following ? :
1)Exhaust inlet manifold and gasket.
2)turbo seals/gaskets - change some or all seals in the turbo ?

I've done a fair bit of reading on the inlet manifold which is within my own mechanical skills set hopefully.

The turbo however is unknown territory for me.

Anyone got any links to part numbers or advice regarding changing turbo oil seals/gaskets.

Thanks [emoji106]
