A bit of oil is normal. The orange seals are cheap, if you’re replacing the lower one just make sure you order a lower one. You need to create a bit of wiggle room on the plastic pipework: unbolt it from the two brackets that go along the length of the pipe. Then undo the jubilee clamp from the rubber hose that it connects to (in the engine bay). That way, you can shift the plastic pipe backwards to remove the orange seal. Easy job.

50-70mm👍

I had this challenge recently and by god it's hard to reach. But I found there's an opening between the gaps towards the driver side (UK) of this hose, you can use a small 1/4 drive ratchet with an extension bar (I had 150mm), a universal joint, and a 7mm socket attached. (Or whichever size the bolt on the jubilee clip is) You should be able to fit a hand with the ratchet up through the gap and reach the bolt with that extension. It's still a tight fit but enough to give you leverage to tighten it properly.

And got triple fuel consumption

Simply aligning the crankshaft using timing marks is not precise enough, so to be sure the pin slots in without forcing, it's easiest to rotate the crankshaft clockwise 15 degrees, then insert the tool, then rotate anti-clockwise again until (the webbing of) piston number 5 locks against the tool.

Yes, and take care not to rotate the high-pressure fuel pump once it's off.

Yes you can hear turbo noise on sudden gas pedal lift-off's after resonator is replaced with silicon hose: ruclips.net/user/shorts-fxfS8E5Z-E Some might enjoy this sound. I don't.

@@atmosphericrecord me too removed the resonator, but nothing similar sound as your. a can't hear any change

@@atmosphericrecordI have this noise on my XC90 D5 - have not replaced anything yet - what is the cause of this hissing noise? Exactly same as on video you posted.. thanks if you can advice!

Turbo is now more audible: ruclips.net/user/shorts-fxfS8E5Z-E?

when in doubt, replace. they are much cheaper than a seized engine

I just had this issue rock up yesterday and stopped the car. It started flaring very ridiculously in 4th and 5th. Instead just kicking it no gear, it flares over 3ooorpm and upto 4ooorpm. So after stopping the engine, waiting a bit, I drove off and the flaring was minimal. Still there but not as bad. I need to run a diagnostic to check the codes because this video somehow hints at the issue that I may or not have since I replaced my loom as the older loom had some knacks in it. This one has a few but much lesser breaks in the loom or at the connectors. Car starts first time and very strongly too. To add, I had a mild flaring issue when the engine is hot. Nothing when it's cold.

I've done the atf flush which improved the changes dramatically but it tends to return after a time do now I'm thinking the valve body needs a clean up

@@nabeeljacksonrhoda6480what ended up being the issue? Did you fix it?

Check for any leaks around your injectors, lifter noise is quite audible on idle and low to mid revs.

@@tropixmedia7325 thank you very much for the quick reply it’s very important tip for me I was suspecting injectors from the very beginning I have even bought one injector and start replacing them one by one putting one secondhand injector I bought but actually nothing has changed also I have noticed I’ve got different injectors Some of them if not all have been replaced because they have different numbers and some of them are class 2 others class 3 … but this is very important for me if lifters clicks always then I will concentrate on injectors thank you very much again

@@pedroleonowicz is your engine an euro 3? (Black engine cover) if so, the injectors all need to be the same class number also, injectors on these engines CAN NOT be refurbished, plenty of information online of complaints and problems from doing so. Make sure the injectors you have arent reconditioned.

@@tropixmedia7325 I have No idea …is xc90 2005 reg. T5 TBF I bought it with this noise month ago…I’m really appreciating this source of knowledge do you think is euro 3 engine I do most of repairs myself but I am window cleaner not Mechanik…But I’m driving old cars for almost 30 years and I’m accustomed to repair my cars

@@pedroleonowicz Euros 3 don't have a DPF, also the rocker cover on the Euro 3s are silver and not black. The Euro 3s have, as you mentioned 3 classes of injector.

If you have black smoke under boost then yes, most likely you have a boost leak. A tell tale sign is oily mist around the joints. The pipe in this video is a very common failure.

@@tropixmedia7325i have oil aroudn the joint of this pipe - pretty dirty actually and my car hissing like hell when taking my foot off - so shall I replace right away? Thx man

A broken shaft is no joke.

@@tropixmedia7325 nothing worse than a broken shaft..

Gently

@@tropixmedia7325 do you use two hands??

My uncle does

@@tropixmedia7325 🤣

Lifters needed changing yes, £100 for a set on ebay. Check rocker arms for scoring, will make alot of noise if not changed also.

@@tropixmedia7325 THANK you for your answer is it possible to check it without removing camshaft?

@@Adam19832 in a way yes, if the lifter seat has been smashed, you'll notice straight away, by then it's too late and you'll need a new cylinder head. However, if all seems fine then usually the lifter has collapsed, or broken apart but not damaged the head. If you notice a loud tapping noise and pulsing sound from the airbox, get it seen to asap. Lifter issues on these engines are caused by the 0w30 oil, I use the 5w40 oil a4/b4 oil personally and have not had a single issue since the repair. EURO 3s never suffered a single lifter issue due to the recommended thicker oil they had. The thin oil on the euro 4s prioritises MPG and DPF efficiency.

Also to mention, diesel enters the sump from failed regens which dilutes the already thin oil causing the problem.

@@tropixmedia7325 do you still have dpf and using 5w40? You mean the problem with vavle rockers is because oil. You mean less protection on higher oil temps?

No it don't, its more of a preventative measure. Also durable enough to handle higher boost pressures if you have the car remapped.

Actually it does effect. Hear the sound when resonator replaced with silicon hose: ruclips.net/user/shorts-fxfS8E5Z-E?feature=share

Are you cranking it with the bolt loosened? You are meant to as this will pressurise the rail and purge the air, easy start is never recommended, as it has been known to bend con rods in the past due to how volatile it is. Double check you have tightened all fuel lines including the metal fuel pipe nut at the bottom of the HP fuel pump, that is an easy one to forget about. Also check ALL connections. If the fuel is delivered around the system while in position II then it should do so while cranking.

I'll upload a video soon to show in detail if that will help, it will demonstrate it better.

Also I forgot to mention, make sure your absolutely certain the timings correct, did you keep the pins in place when tensioning the belt and torquing the sprocket, misaligned timing can cause the problem you describe. Especially if everything worked before you stripped it.

Thank you, apologies, I thought I responded.

Make sure the cam sprocket notch is aligned with the mark on the cover, tension the belt THEN torque the sprocket bolts. Remember to always turn the engine by hand a few revolutions to make sure there is no interference (very important) Going by what you've said, you probably have air in the fuel lines hence why your having problems starting, start by cracking lose the large bango bolt ontop of the HP fuel pump, turn the engine over then it should start as your purging most of the air out of the system, this is what I did when I had this issue the first time, remember to tighten the bolt after loosening.

High pressure pump faulty. replace it and it will work. no need for priming bosch one designed to bleed it self

@@gbmultit2222 not always true, it can take alot of cranking for it to self bleed, usually resulting in the battery going flat.

Hi, you helped me when I did my valve body, I've just changed my rockers and lifters but now engine won't turn by hand, did this solution work for you, thanks

Thank you.
