Rocker arm replacement info/suggestions Anyone done the job, how how doable DIY?

[a4huey09]

Looking for advice on replacing a rocker arm it's on the passenger side front of my 2016 rs7 based on the noise I'm trying to get an understanding if it's something I can do myself by without pulling the engine, from some of the videos I've seen I think I could get enough space to get to the front rocker by removing the camshaft carriers while leaving the cam shafts and cam chains intact/attached. This is assuming it's one of the front rocker arms which I'm fairly certain it is.

Does anyone have any experience with this?

Dealers and indie shops are quoting 10 to $15 K range to pull the engine and do the job.

I understand it's not the complete /right way to do it ( i.e pull both heads replace all rocker arms with new updated part number designed arms etc) but I just want to get the vehicle into a stable state.

I have no experience with removing cams on the 4.0T but if it's anything like the other FSI/TFSI engines you'll be pulling or at least lifting the cams up out of their journals to do it.

You could do the work without pulling the motor. You are going to end up pulling off a majority of anything currently on top of your motor though. It'll make the job a bit more tedious but it's still doable.

Unfortunately, whoever told you you could remove the rocker without removing the cam had no idea what motor you were talking about. The top of the cyl head you see IS the top camshaft carrier for the head. You pull that cover and the cams come right out. What that means is that you also need to effectively do the timing for the cams, so you'll need the timing tools to take tension off the chains. Doing that with the motor in the car is tough and then getting it all sealed up, including coolant plumbing (which goes through the cam gear cover) can be fun for a first timer.

These are a good multi-view of a head with the cover and all the bits in place and then removed. You'll see what you are up against.

Svarog is always good to see exactly what you are facing when looking at the 4.0t. You can see all the parts you'll have to access and what tools you'll need to be able to do this!

Again... doable, because the upper chains are meant to be able to be serviced while in situ. You are also looking at a lot of ancillary parts i.e. o-rings, gaskets, sealant that go with any normal cyl head reseal.

Now you might understand why they want to pull the motor!!! Resealing things is SOOOOO much easier when it's out! No climbing over the motor for 1/2 the job!! If you do decide to do it in car, at least remove the front end (not service position). It's a lot easier to reach everything you need to.

Personally... if I intended to keep the car, I would pull the motor and do a lot of refreshing on all the wear points and things that go bad.

But that's me.
