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

Thanks that is a good plan.

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.

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 simon

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?

Certainly there were a couple of years with nothing in the service book but was a company car at that point. 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. 162,285 and I drive it about 30 miles per day when commuting with some long motorway drives about twice a month. From cold but more pronounced under load. 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. 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.....

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

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?

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? 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.

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

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.

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?

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.
