Seeking knowledge

Very interesting read, thanks for that! The Forge pipes were simply suggested as I was fantasizing over pretty colours but that thought has passed!

My coil packs are not due a recall, phoned VW and checked with their database so all good. I'll keep my eye on them though, and replace if required. Downpipe and sports cat... Now I thought it would only be worth doing that if you go stage 2 tuning, but I may have to re-consider my approach, however the R32 rear bumper has been acquired so fitting a full system may be the simplest option, allowing future upgrades without the need to think about the exhaust system. K04 upgrade would be lovely, but a long way off just yet.

Cam followers, what's the symptoms of failure from this component?

Also, I have a K&N panel filter in my air box, but was considering a VW Racing intake system but will consider the system you mentioned. I've not come across that manufacturer so far in my travels.

The re-map will come after a upgraded DV valve (the Forge kits look the best to me), exhaust and a possible intake system upgrade too. Figured there's little point in mapping the ECU before all the additions and changes to the engine have been carried out. But it will be one big spend over about 3 months I think, probably over the winter when there's little else happening.

The cam follower is at the end of the high pressure fuel pump and permanently rubs against the cam lobe. Over time these wear and can eventually fail catastrophically taking the cam lobe and pump piston with it. As it is a relatively cheap part it makes sense to check it periodically for wear. When new it has. Black coating on its face and if it looks like it is starting to wear off then it is time to replace it.

The forge DV wouldn't be my choice. It isn't a fit and forget part as it needs lubing periodically. If it dries out it can stick. I've found that either the EVOMS manual DV or the GFB DV+ with the new revision piston and spring would be best......if you must change the OEM DV.

OK, but the GFB DV+ bolts onto the OEM solenoid, just replacing the weaker parts? Should I buy a whole new OEM DV (latest revision) and then fit the DV+ parts before installing, or just the DV+ parts? (And it's also cheaper to do this, yay!)

Have now added the down pipe and sports cat to my shopping list, and will get some quotes for fitting cost ect... Could fit the DV+ part myself I reckon, doesn't look as involved as other options, and will research the cam followers this afternoon (how to guides and parts ect.)

Cheers for your advice, having read your project I'm quite confident in your statements! :-)

Also, having searched through the forums and what not, I've noticed there seems to be an issue with using oiled panel filters, like K&N ones (which I have). What are the symptoms of it and would re-mapping cure them or would something more drastic be required?

[Hurdy]

It would make sense to buy the latest revision OEM solenoid to go with the GFB DV +.

Oiled filters, whether panel or open cone have advantages and disadvantages over dry filters.

- oiled filters need cleaning and re-oiling periodically.
- oiled filters can "seep" oil through and this can foul the MAF sensor causing the car to run roughly.
- oiled filters do filter out more particles than dry filters
- oiled filters aren't as efficient for power as dry filters.

I run a dry cone filter.

Ah, OK, but baring in mind my stage of tuning, having cleaner air is preferred than performance at this stage? Until I go beyond 25% power increase, is it worth worrying about?

Also, I though the solenoid itself wasn't changed through the revisions but just the diaphragm, or am I mistaken? The GFB DV+ replaces nearly everything bar the solenoid and the yellow O ring.

And with regards to cam follower, is this the correct part?

And is this guide the right way;

And yet another question regarding PCV valves. Been led to believe the the stock OEM fails regularly so it's either replace with an ECS OEM Update (£110) or could I go with this, for just £50 more...

Opinions/reasons for and against..?

Thanks.

The latest OEM revision will do the job.
