Help with finding a PVC system, replacement kit & coolant flange
 

I need help, looking for a complete, PCV replacement kit and coolant Flange for my 2001 Audi A4 1.8T AWM :) I looked on esctunning and was completely confused with the kits they had on it. someone, please assist. :confused:

If you want to replace the entire PCV system then I would suggest 034's silicone breather kit.

If you don't want to spend that much, then you could get by with replacing the block elbow and T fitting as those are the common leak points.

Block elbow: 06A 103 213F

T-fitting: 06A 103 247

You should be able to get those two parts for less than $50. Make sure to get a new o-ring for the block elbow. Also, I wouldn't call those two parts easy to replace. You'll be working in very tight spaces beneath the intake manifold and will have to remove a couple of the pesky one time use clamps.

Thanks basedrifter :)

what about the coolant flange? :confused:

AWM OEM coolant flange: 058121132C

Flange to head o-ring: 037121687

Flange to coolant pipe o-ring: 058121687

awesome! Thanks man. I added those part numbers to my Reinforced Silicone Breather Hose Kit.

Total is $142.33 not bad, considering how much, esctunning is charging for it's kits and OEM kits, that's not even silicone. :)


Can you vouch for this kit? did you install it in your B5? :)

Yes, I installed the 034 breather in my car a few weeks ago.

I wrote a DIY article here: https://www.audiforums.com/forum/diy...-early-199692/

It's written for an AEB, so your AWM will be a bit different, but the same concepts apply.

you're awesome man, thanks a lot. I just pulled the trigger and ordered the parts.

I'm leaking oil and i didn't know from where, until i finally got my Russian mechanic to finally look at it and tell me, where the oil is leaking.

This after i got my rear main seal, valve cover gasket, half moon seal and the gasket seal and Both front camshaft seals, replaced and still was leaking oil!!

So i hope this settles the oil leaking issue. ;)


is there anything else i should replace, while replacing the PCV system? Do you know of a vacuum hose kit? maybe i should do that, while I'm at it? please point me to a kit on the same site if you can, being i prefer to buy, everything at once on the same site if i can.

It's always a good idea to check the vacuum lines and replace them with silicone. I believe 3mm for the smaller lines and 5mm for the larger ones.

ECS and 034 should both carry vacuum hose.

do you have a link for a kit?

No, there are no kits. Buy some tubing, remove the old line, cut the new one the same length, reinstall.
