1.5 dci blue smoke cold and noise



  Clio 2 1.5 dci
Hi guys,i have 1.5 dci 60kw 82hp clio 2 2005, there is a problem from start, engine when is on first start no smoke at all even in minus degrese, but if i when is cold start reversing fast an realase, burned oil is smell and there is a blue smoke, if i slow get to 2k and hold no smoke at all or if i drive cold on stucked rpm 2k no smoke at all. If I accelerate fast when is cold till i get rpm (2k) there is a blue smoke and then stop smoking. And there is a noise when is cold like ticking noise. I know its oil in combustion proces. And when engine warmed up noise almost disapear and smoke when accelerate also disapear. I tried with inlet pipe remove, same thing happend(to inspect turbo). I changed valve seals again same thing. I forget to inspect valve guides when i changed valve seals without remove head. And i done compression test dry on cold engine, and compression is 28bar on each cylinder. I dont know will wet compression test show oil rings or scraping ring, if compression ring are good? Thanks an advance. P.s sorry for bad english

Turbo or piston rings need changing. Take exhaust off at turbo and see if any oil on the turbine.

I already removed inlet mainfold pipe, and test it and same again. I put new turbo 3 weeks ago. Old was bad. But without turbo and egr still same. Is any way to inspect piston oil ring or scraping ring, i already test dry compression test on cold engine and reaults are perfect

You will to strip the engine to inspect. Worn piston rings are common.

Can turbo leak into exhaust cause blee smoke when cold revers, and when get hot seals expand?

As above take exhaust off and see if there is any oil deposits on the rear turbine, if its wet with oil turbo is bad, if its normal soot then its ok and its issues with the engine
