[Dilemma Scout 07 - fix a worn inlet valve or sell the car for spares / repair?]

Yes good plan. Not sure about the bypass or flow question.  

[Dilemma Scout 07 - fix a worn inlet valve or sell the car for spares / repair?]

Thanks that is a good plan. 

[Dilemma Scout 07 - fix a worn inlet valve or sell the car for spares / repair?]

Thanks for the heads up. I will definitely be checking those areas for swarf and hopefully avoiding the costs of a total rebuild. 
 

I will let you know what I find.

Perhaps checking the oil pump pickup for debris.

Yep poking around the oil in the area around the injectors produced a bearded magnetic screwdriver!! 
 

thanks for your input into this. 
 

I cannot help feeling that someone replaced the rocker shafts and skipped the cam at some point in the past...

 

cheers

So I have just got the injector rocker shaft off and found:

 

Cyl 1 rocker lobe deep gash in the metal 

 

Cyl 1 first lobe (inlet?) tip to toe 57.75mm

 

Cyl 2 first lobe 61.79mm 

 

Cyl 3 second lobe (exhaust?) 60.75

 

Cyl 4 second lobe very worn

 

Basically all but one of the lobes shows sign of wear but the lowest above was the worst by far. 

 

Have just ordered a new kit from Engine Team. 

 

Question though about how that deep gash could get there and the corresponding rocker is damaged?

Has the engine had regular oil/filter changes with the correct grade of oil for a PD?

Certainly there were a couple of years with nothing in the service book but was a company car at that point.

Has it become more noisy? If so describe.

Firstly I have noticed a more tappet type noise from it but have become used to this with diesels.  When accelerating the misfire noise becomes more apparent.

What's the odometer reading/how is it driven?

 

162,285 and I drive it about 30 miles per day when commuting with some long motorway drives about twice a month.

When does the misfire occur? Cold/hot, low/high RPM,  under light/heavy load..

From cold but more pronounced under load.

I'd suggest a more informed opinion before whipping the cam cover off for a peek but it's certainly looking likely your problem is there.

I will certainly try to get a more informed opinion on it and have one local to me who may well be able to help from a VAG perspective.  I will probably also do a visual because a) I have already bought a new gasket :-)) AND b) there is a small oil patch oozing from the seal near the tandem pump so I can fix that as well.

How do you know the injectors are working fine?

My AUTEL system shows them to be operating normally but to be honest who knows!

 

Oh well will need to get to look at the next bit and if it is camshaft at least I can change the belt and waterpump at the same time.....

[Dilemma Scout 07 - fix a worn inlet valve or sell the car for spares / repair?]

There is a bit of 'back draft' out the intake.  Could the lobes issue cause that or is that a red herring?

The misfire will be caused by a lack of fuel (injector loom etc) or a lack of compression (valve/seat damage).

Hi.  Thanks for the advice to date.  Completed a test of compression and got 29 bar on all cylinders so i guess the issue is elsewhere - either injector loom or maybe turbo?

HI

 

I am just about to commence a strip down of my BMM.  Any chance of a down load of the manual?

 

Apologies Just saw the latest link and that is working fine!

 

Hope your BMM is working well for you?

Done a full rebuild on mine so any questions feel free to ask

 

 

Ah OK!  Is yours a BMM as well?  I am very tempted to give it a go to be honest because apart from this issue it drives very nicely.  Saw another BMM at the mechanics this morning and mine is definitely in better condition than that one was....

 

It would be great if there was a list of items that need attention on these engines and then a list of the parts needed to sort them out!  Still Haynes is good and there are some great apps online for getting the parts through these days.

 

How long did it take you Mike?

I am currently in West Sussex (near Gatwick) for 2 weeks and brought my VCDS with me if you want a free scan and a look over, PM me if that would help you decide what to do.

 

That would be great.  I will PM you as I am very near to Gatwick.

The misfire now happens all the time. Rough running at anything over idle, then losing power over about 2000.  My commute is about 10 miles each way and on one day about 30 miles each way.

I'm not familiar with the garage labour rates in your area but that does seem a little steep for head off, reseat valves, replace seals and rebuild.  Are they suggesting skimming the head as well?

 

To be honest i am not sure how long it would take though I am sure most of it is labour...

Apart from doing what @J.R. suggested give some thought to the condition of the car as it is otherwise.  Is it a clean runner or does it have other problems?  When was the cambelt last done?  Is the clutch OK?  Tyres, brakes etc.  all these add up when looking at the value of a car to keep versus sell.

 

I'm assuming yours is a 2.0tdi 6 speed BMM engine?

 

HI - Yes I have taken that on board.  It is the model you suggest.  Tyres and brakes are recently changed....cambelt done at 116K.  Clutch I am not sure, seems OK.

 

They have quoted £1300 to complete the job.

[Dilemma Scout 07 - fix a worn inlet valve or sell the car for spares / repair?]

Hi 

 

Just need some advice really.

 

My Scout started having misfire issues, intermittent, but getting worse.  I checked the data readout and it was showing a glow plug open circuit and after going through this forum decided it was a wiring issue, even though the injectors seem to be working fine.

 

Took it to my local trusted independent to sort out and they have come back and said it is most likely a damaged / worn inlet valve and will need to replace all valves.  

 

Clearly the cost goes way beyond what the car is worth, so the question is what to do.

 

Any thoughts?

[Blower fan issue]

HI

I had this issue with my Scout and it was a fan motor getting clogged up with dust.  The fan came on intermittently then would stop and not come on again.  I gave it an air blow to the motor and a squirt of WD40 and it has worked pretty well ever since.  Hope that helps.

[Key fob battery]

Thanks for the link - worked a treat!  I hate having to invent wheels - I am not that clever!

[Egr cooler]

Hi

 

Did you get this done and did it cost around £1600?

 

Thanks I have a Scout as well and think it needs doing on mine.....

Not mechanically minded, and not trying  to misdirect, but like you I have a 2010 Octy Scout TDi. (PD) 

 

Last year I had the EGR Cooler replaced after smelling 'exhaust'  gasses for quite some time. Going by the location of the engineer sent out to assess the issue, I believe it to be located low down and towards the back of the engine. 

 

Best wishes resolving this. 

Hi

did this cure the problem? 

[Manifold gases on scout]

Hi. I have Scout 2008 Octavia and also have this problem. Took it into Kwik fit for a check and it seems fine. I suspect that the fix will be a new EGR.
