Oil leak in spark plug holes
First post in a while- this is on my 4.2 2007 FSI motor. 142K on the clock.
I have the dreaded camshaft girdle leak.
What is the latest and greatest fix for this?
I found the leak sleeves that get pressed and RTV'ed in through the spark plug holes themselves, but have not found any reviews or anyone that has tried them. And $400 for the 8 sleeves is a big pill to swallow.
I have the engine torn down to pull the cam girdles currently, but I am at a stopping point as far as how to get the rear timing gear adjuster covers off of the back of the engine. There are 2 SAI (secondary air injection) valves that are going to be impossible to pull due to where the tork screws are behind the rigid air injection lines that feed air into the head are positioned.

Did some research, the Audi manual states the rear timing covers can be removed in the car. There are coolant pipes on each rear timing cover that pass through a jumper pipe/seals that need to be removed. And the SAI hard pipes and check valves need to be removed. These looked like they would be a major PITA to remove.
I ended up purchasing the oil leak repair sleeves from www.audioilleak.com and couldn't be happier. These can be installed without removing the valve covers (I removed mine because they were leaking to replace the camshaft cover seals....)
The oil leak sleeves fit perfectly, and were a great alternative to the amount of labor it would have taken to remove the camshafts and cam girdles.
If anyone is interested, I did make a youtube tutorial on my issue and repair.

Looks like a good fix compared to the alternative. The V10’s suffer from the same problem as they’re the same architecture. Weird why they don’t offer a 10-pack. Then again, easy enough to just buy a 4 and a 6-pack, as they’re all the same size.
As they’re just held in with silicon, rather than an interference fit, I doubt it’d cause any issues with disassembly should you need to go that deep.
