Hi Gary,
Thanks for the info , do the breather hoses block up with grot? On these engines leading to an increase In pressure in the rocker cover.
Thanks

Hi Matt,
It's not a massive problem to resolve, and you won't need to disturb the cambelt.
Rocker cover gaskets are available for the TDi's, however it is common for a repalcement gasket NOT to cure a leak.
The recommended method for many indy's and main dealers is to replace the cover in full.
A new rocker cover comes with the new gasket in place.
I believe there are some differences in old and new covers or gaskets.
Part No's:
Gasket (seal) - 045 103 483 C - approx. £20 +Vat
Complete Cover - 045 103 469 G - Approx. £90 + Vat
Cheers
Jeff
.Ive Removed and replace cam covers on several TDI Engines now and never had a leak , ive only replaced the gasket once because it had gone a little brittal , main thing is to make sure is you undo the securing bolts in the correct order, reverse of the tightening sequence , 1/4 turn at a time so the cover does not get warped , more so during tightening id imagine but better to be safe than sorry, make sure the rubber seal is clean and the alloy top it sits against on the cylinder head is also spotless, youl also need a small amount of Blue hylomar or something simular as the seal neads this adding in four places before refitting. on the rocker cover youl notice the 2 half rounds where the cover goes around the camshaft , in each of the 4 corners youl need a small amount of blue hylomar

How did all this go in the end Phil?Oh dear found 3 maybe 4 oil leaks:
Right hand rear most corner of engine cover. Cover off, checked for flatness, seal good, waiting for blue hylomar to arrive. Correct tightening sequence and torque will be used.
Rear of engine at the engine cover, just to left of the bump in the head. Just where the hylomar should be applied. As above.
The injection harness securing boss:
The white seal appears to be in a bad way:
The back of the engine is very wet:
Possibly the fuel pump gasket but I'm going to start with the highest two leaks and see if it stays clean.
Any comments / other things to look for?
Hi Phil, tha ks for the info there, I have had a brand new audi cover fitted when they removed the egr, so my guess is either they didn't blob it with sealer or they didn't tighten correctly. My next guess will be tandem pump as I'm still.running original pump.@CrispyEdd today had to use a 3/4 drive ratchet and 36mm socket on the hub plus family pushers and a L driver to get the A2 inside. It could be there for a while so from memory:
Leak 1, cam cover. Needed a new cam cover compatible with the new seal. Apply sealant as in the manual and torque down in sequence and then that leak gone. Could only do that by removing the EGRV.
Leak 2, tandem pump. Tandem pump rebuild kit came with a gasket without silicone blobs. They leak; it did. Tandem pump replaced with new Bosch and genuine gasket. Leak gone for a couple of years. Gasket replaced with second genuine gasket, leak gone.
Leak 3, injector harness seal. Not available without harness and harness now NLA from VAG. Smeared engine silicone all over it. Leak acceptable.
Car develops misfire, replace injector harness; so assume leak gone, but haven’t completed the repair.
Stripped two cam cover screw holes, cant get drill or Hellicoil to them. Car stuffed; working on it.
