CrazyDave 0 Posted October 21, 2006 Sounds very unusual... I had a timing chain rattle on my 69k mile Corrado. When I removed the tensioner and removed the plunger from the big bolt head part, I noticed a very small lump was missing from piston seal. So when the engine had been standing for a while you could really hear the chain rattle on starting and about 1200rpm when warm. Worth a quick check, just make sure you bleed it properly before you put it back in again. Lots of guides if you search on the forum. Anyway I replaced it with a new part and it's been silent ever since. Quote Share this post Link to post Share on other sites
Taggart 0 Posted October 21, 2006 Yeah, that seems very early to be worrying about chains. But we all know how variable these engines are, mine needed a rebore after 60k. Quote Share this post Link to post Share on other sites

Andi 2,147,483,647 Posted October 21, 2006 I'm sure this will help... http://www.the-corrado.net/wiki/index.p ... ent_Part_1 Gotta be something useful in that lot ;) Quote Share this post Link to post Share on other sites
CrazyDave 0 Posted October 22, 2006 Some pics of my faulty tensioner. Now I don't know if these are the same on the later engines but should be similar. This is what the complete tensioner looks like. And this is the piston when removed. Note the split in the seal. The large bolt lives on the right hand side of the engine at the back, probably under a few plastic covers. Hope this helps? Quote Share this post Link to post Share on other sites
g60bv 0 Posted October 22, 2006 that is perfect. . is it just a case of replacing those bits.? also you say that bolt/ tensioner is faulty. how can you tell.? thankyou every one for this infomation. Quote Share this post Link to post Share on other sites
CrazyDave 0 Posted October 22, 2006 The tensioner comes as one piece, the picture shows the centre part removed and the brown seal has a lump missing from it (middle of the white scribble, sort of black dot - sorry the pic is a bit fuzzy). Best bet is to remove the one from your mates car and pull it apart. Inspect the brown seal for damage, it should have a nice even sharp edge all the way round. But before you start, make sure you have a 6" deep tub of some kind to fill with clean engine oil. Because before you put it back it needs filling with oil and all the air / bubbles etc need bleeding out. Do a search, plenty of guides around for this. But basically you have to immerse the whole part and work the plunger in and out to get it about half way out. It's a bit trial and error and it will pump up on it's own but it needs enough to keep the chain tension while start for the first time. Quote Share this post Link to post Share on other sites

NickVR6 0 Posted October 22, 2006 We bought my wifes vento vr on 58k and it it had a little chain noise. It also had full vag history, but im sure thats not the cause ;-) Anyway, its got progressively louder and is now on 120k and is, well, very very noticable at 1200rpm, textbook tensioner noise. But there you go, it still get used "properly" and we are pnly just kinda thinking about doing it now. From discussions i've had, its not rocket science but is a big, time consuming job. Parts will cost you around £400 to do the basics properly as you may aswell do the clutch while your in there. Its gearbox off, front off the car, rad out etc etc iirc Quote Share this post Link to post Share on other sites
