Hey, Brit living in spain here

My pcv system is messed up. I was getting exhaust smells coming in through the air vents as soon as I fired her up from cold, so assumed a leak in the exhaust system. After reading up on here, and a mechanic telling me there was nothing wrong :icon_eek: I located a massive crack on the crankcase breather elbow. Pretty obvious when you knew what to look for. I won't be using that mechanic again as I had already told him I thought that the PCV might be the source of the problem.

So, how easy is it to replace this system of tubes with really, really basic tools. I mean, I have a few smaller spanners and a couple of socket sets and screwdrivers. I am a plumber and heating engineer by trade and, after watching a you tube vid of a pro doing it, I think I can handle the manual side, but do I need specialist tools for it. I really dont want to take the intake manifold up as fuel systems etc are waaaaaay out of my ball park right now but I hope to build up my skills over time.

Oh and any good links to suppliers of the parts in UK or Spain would be really helpful


Mind how you go

For the V6, it's easy, except for the one rear hose coming off the dead-center back of the engine. I wouldn't replace that one on the 1st go-around, as it's very difficult to get any tools on it, or your hands, to release the end. Also, that's not a likely hose to be blocked, IMO. There's a DIY in the info forum, as well as a straightforward youtube video. You might need some sharp snips to cut the one-time use clamps off for the valve (replace with re-usable ones). Other than that, it's like a screwdriver, a socket to remove the plate cover (to access the valve), and strong fingers. If the PCV pipes are old, the ends will probably just break off in your hands. It's like the first DIY I did on my car - if I can do it, anyone can.

Its the 1.8 turbo 20v flat four I think. Watched my video through and a shop vac looks essential and I dont have the money for extras right now. I think to the garage it shall go this time. Just gonna go and check the engine code on it.

What model year? A photo would help greatly.

PCV Systems for the 1.8T range from relatively simple (as on the AEB 1.8T) to WTF were they thinking [comply with US emissions laws] (as on the 2003 to 2005 AWM 1.8T).

From a photo, the forum can give you deeper advice. You may discover some smaller 8mm ID lines under the intake manifold that likely also have brittle plastic tees and likely check valves. I replaced the 8mm plastic tee (AEB 1.8T) with a brass tee.

"comply with US emissions laws" - that's their new motto, ain't it? CEO just got indicted. Oooops.

I shipped my car from Texas to Madrid where I lived for 5 years before shipping it back to U.S. again. Where in Spain do you live? If you are in Madrid area, I know a couple of mechanics in Las Tablas area who are very good and reasonable in repair fees. I bought some after market parts in Spain but was not satisfied. It's better to buy from the dealerships.
