J.J. 0 Posted February 3, 2016 Report Share Posted February 3, 2016 So, I'm having to replace the VR6 in my Scirocco with another one.. (Another story for another time) I have the replacement engine ready to go in, well almost.. After having a quick look over the new engine to see what I need to order for it, I've noticed this pipe has rusted very badly, probably to someone running the car on just water for quite sometime.. whatever, I need to fix it.. The one on my broken engine is corroded even worse so I can only assume this is somewhat a common problem with the VR's. So, does anyone know, how to get the rusted one out and if I can get a replacement from Volkswagen, does anyone know a proper name for this part or a part number ect.. All help is appreciated.. Here's a couple of pictures of the culprit. Untitled by Jake Jezard, on Flickr Untitled by Jake Jezard, on Flickr Link to post Share on other sites
rsweeney 40 Posted February 4, 2016 Report Share Posted February 4, 2016 although it looks corroded if it isn't leaking it's probably best to just give it a thorough clean. They are an interference fit, the same principle as the valve guides. So if it needed replacing I'd take it to a machine shop and get them to carefully remove the old pipe. VW don't list this as a separate part of the cylinder head so you could work out the correct diameter of pipe needed for the interference fit, cut a section of this pipe, and then put a slight flare on the end so the hose has an edge to seal against. You could then fit pipe into the cylinder head using a wooden mallet or similair (I would probably use some loctite when fitting this) VR6Pete 1 Link to post Share on other sites

Guest Posted February 9, 2016 Report Share Posted February 9, 2016 Possibly just coat with a kill rust type paint. This will stop any more corroding or oxydising. If its not leaking, just leave it. Link to post Share on other sites
