Remove Head or Motor for Rocker replacement
Hi everyone. I'm new to the forum as a member, but have always found the information on here very helpful as a guest user, however not having owned a VAG car yet I had not needed to register an account. But here I am now, and my German lizard has taken it's first shot at my wallet
So the car in question is a 2005 Audi 2.0TDI with the BLB engine, so I hope you guys can still assist me with this question even tho it not being a VW, but using a VW engine.
Recently I broke 4 of my exhaust rockers on the car, the 50mm one's. Now that I want to replace them I am facing two approaches. I can remove the head, and then slide the shaft the rockers slide over out the head etc. Or remove the whole motor from the engine bay and also slide the shaft out the side.
My reason is that the engine has never been opened before, and the car only has 162k on the clock. A friend suggested I keep the engine sealed as per OEM spec, but removing the whole motor seems a bit over kill.
So I'm looking for some other opinions please. All is welcome and much appreciated!

Re: Remove Head or Motor for Rocker replacement
This is a pd engine, there are no rockers for valves.
There are 4 Rocker arms for the Injectors.

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on

Re: Remove Head or Motor for Rocker replacement
I must have named them wrongly.
The 2.0TDI is a 16v motor, so instead of solid lifters like the 1.9TDI VW used these weak things:
Here you can see the broken one without the roller at the bottom.
These slide over a shaft that slides into the head from the side, now being an A4 the engine is mounted longitudinal and said shaft will slide out the back and hit the firewall, which brings me to my dilemma in the first post

Re: Remove Head or Motor for Rocker replacement
I would rather remove the Head, did you find the reason for the damage? Sure the valves did not make contact with the pistons.Arlow wrote: ↑Wed Oct 31, 2018 7:52 am I must have named them wrongly.

Those are very long shaft and I dont think it will be easy or possible to remove them while head is in the car.
A bit crazy to remove the complete motor for this.

Re: Remove Head or Motor for Rocker replacement
The reason why they broke is a bit embarrassing I was moving the cam pulleys to fine tune the timing a bit, and I wanted everything on TDC before I plug in the laptop with VCDS. I forgot to take out the locking tool on the intake cam and proceeded to swing the engine.....
This resulted in the timing having jumped and now I have 4 broken rockers/lifters. I have written the damage off as school fees.
The valves I hope have not bent as the car was not being driven, but just cranked. I do also believe removing the head is a better route to take, both in terms of labor involved and to check the valves. I just wanted a second opinion on the matter

Re: Remove Head or Motor for Rocker replacement
That starter swing is enough to bend the valve on contact
Better to take the head off as suggested and inspect for any damage to valves etc.

Re: Remove Head or Motor for Rocker replacement
Thanks everyone for your input! I will be removing the head rather than the motor. I will keep you guys posted as time progresses.
@Ashveer I would have loved the locking tool to have just broken rather

Re: Remove Head or Motor for Rocker replacement
Time for an update!
The process has been delayed due to time constraints unfortunately, but I'm happy to report that my car is alive again!
This is the first time I have worked on a diesel, not that much different to a modern petrol engine really. There is not much to report on really, besides that the motor is alive and healthy again. I am also very thankful that no valves were bent, keeping repair costs to a minimum.
So moving forward from here, my plan is to do a remap sometime in the future and some other small mods, nothing hectic as this is my daily car and would like to keep it fairly stock and comfortable to drive.
Here are some pictures of the process
All the old broken rockers
New rockers fitted! Cleaned all the metal shavings and deposits before installing the head on the car
I had a friend make me EGR delete plates as well, seeing that I was in there for the rocker replacements
The first time the car has started in two months! This was a very satisfying moment for me
After coming back from the test drive. I have yet to assemble the car further
