@@danieleriksson1657 You will clean the intake manifolds outside of the vehicle. In order to clean the intake valve ports rotate the crankshaft pulley and make sure to clean the ports with closed valves only. If you don't you will wash all the mess inside the engine which can cause catastrophic engine failure.

Thanks for this. I admire that you did this. I need the exact same repair and know my limits. Does £1700 to repair which includes replacing intake pipe connection, inlet port motor, oil cooler and drive shaft at the same time sound fair to people? Only the seal needs doing, but the suggestion is to do the other bits whilst the engine is in bits as it won’t make much difference to the overall labour cost.

Hello , Vielen Dank für das Video. Ich habe eine Frage - möglicherweise tritt Öl in das Abgassystem ein, und ich weiß nicht, was der Grund dafür ist. Liegt das Problem am Motor oder am Turbolader? Alles andere am Fahrzeug scheint in Ordnung zu sein. Ich habe das Fahrzeug gekauft und der Verkäufer hat mir versichert, dass weder der Turbolader noch der Ölkühler defekt sind. Dennoch tritt dichter Rauch auf, wenn der Motor heiß wird. Der Motor läuft reibungslos und klingt gut. Ich habe auch etwas Öl am Einlass des Turboladers entdeckt, wie im Video gezeigt.

@TheKeenMechanic 9 күн бұрын

Hello, thank you for the video. I have a question - maybe oil is entering the exhaust system, and I don't know what the reason is. Is the problem with the engine or the turbocharger? Everything else on the vehicle appears to be fine. I bought the vehicle and the seller assured me that neither the turbocharger nor the oil cooler were defective. However, thick smoke still appears when the engine gets hot. The engine runs smoothly and sounds good. I also discovered some oil at the turbocharger inlet as shown in the video.

@TheKeenMechanic 9 күн бұрын

I have posted the translated message in English so others can read it too. It is hard to tell without inspecting the vehicle in person. Is the smoke Black or Blue/White? If it is black smoke the it is most likely not enough air to burn the diesel. If it is blue/grey/white smoke it could be oil/antifreeze coolant leak. It will be very hard for oil to pass through the combustion chamber and to end up unburnt in your exhaust system. Make sure you have no turbo boost leaks which will cause the black smoke. This ML350cdi shown in the video was working very well when idling, but had no power and smoked black due to boost leak from a sensor that was not fitted correctly and had fallen from the plastic manifold which goes to the aluminium intake manifolds. Check the engine 1st and make sure you have no obvious boost leaks. If you know somebody who has a smoke machine get him to pressure test the intake system and check for leaks. Hope this helps

@@TheKeenMechanic The smoke that comes out is blue, a lot of oil enters the exhaust system / Sometimes white smoke comes out when the engine temperature risesThe engine runs smoothly and no malfunctions appear on the screen ,But the problem is the smoke and oil in the exhaust system

@TheKeenMechanic 9 күн бұрын

@@MN-nl3kp hi If there is nothing obvious you can replace or rebuild the turbo and see if this solves the problem. I found a company here that sold me a fully professionally rebuilt turbo for around £300 when I returned my old one. I hope the place you purchased it from offers a warranty. Check if coolant is leaking into the intake valves from the manifold. I have seen this before. This causes light coloured smoke too. Hope you get it sorted. 🤝🏻

@TheKeenMechanic 4 ай бұрын

This was my 1st experience with OM642 engine. I had big trouble removing the 3 bolts at the back of the turbo which took nearly 6 hours by itself as I had to bend and weld custom tools to loosen them up without snapping them or rounding the heads. I would say all together with all trouble, cleaning and filming took about 30hours. If I was doing it again it will be 12 to 16hrs with good detail. I have heard others doing it for 8 hrs but I assume they did not go into such detail and cleaning. Consider yourself lucky if you get this done for under £500. Gaskets, seals, Oil, filters, coolant, cleaning chemicals and consumables increase the price even further. Hope this helps
