Hello,
I’m looking for some advice and tips on removing the sump on my B7 A4 2.0 TFSI Quattro to replace the pick up pipe as I’ve got a chain rattle coming from the top rear of the engine which I believe to be the cam chain which has a hydraulic tensioner. I’ve never had the oil light pop up but I’m thinking as this tensioner is the furthest from the oil pump that it’s just not getting enough pressure to keep the chain tight enough.
Anyways - I’ve been doing a lot of reading on this and just looking to get a few things cleared up before I start it this week.
1. Does the subframe need to be fully removed or can it just be loosened on the bolts and moved down slightly?
2. Does the air con pipe that runs right under the sump have to be disconnected? I’ve seen someone say to just remove the 3 bolts holding the air con pump on - how do you take the tension off the belt as I would rather do this than lose all my gas!
3. Any specialist tools required? Seen some mention a long 5mm Allen key to get the bolts behind the flywheel but some say they can be got with a wobbly joint and a 10mm socket.
4. Is loctite 5922 suitable for sealing the sump again? Audi want £25 for the sealant which seems ridiculous!
5. Final question - is there anything else besides the pick up pipe that I need whilst I’m in that area and have the sump off??
Cheers
Jamie
