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 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?
