    Hey everyone slight problem for past few days I have been taking the d.v valve off and the hose which connects to the tip it's this hose which is full of gunk looks like the gunk in the stickies when a member installs a catch can and removes light brown gunge out.
    I have ordered the last remaining hose which I needed so altogether I have the fittings and clamp etc.
    My question is that will all this gunk go in the catch can once installed and after the install should I use 1 step thicker oil.
    Currently I use quantum 5 w30 but I require a top up more often than I need to top my mobile lol car is s3 8l 150k ish
    Thanks everyone ...Silva bullet

    Yes, once you connect crankcase vent outlets to a catch can, thats where all the oil vapour will collect.

    As im sure you know factory set up re-introduces crankcase pressure (oil vapour) into intake system

    Evening samhendry I have in the past took off the hose connected to the tip alot of times 5 years of ownership but never hav I found this gunk it has always been oily but not gluey brown gunge I was today literally fishing it out with a hose clamp screw.
    Should get my hose in the post in a few days so will try the install.
    Is it worth me 5 w 40 quantum aswell asi hae always put in 5w30 but keep getting empty reading on the dipstick really paranoid so put in a litre or so every few hundred miles or so
    Thanks for your help mate...Silva bullet

    Litre every few hundred miles doesn't sound normal to me. Is it burning oil?

    I use 10w40 mate. 30 is too thin imo

    I don't understand why the gunk is in the Diverter Valve? To get to that the gunk needs to go through the vacuum hoses and potentially N249 valve etc. do you mean the hockey puck?

    it does seem like quite a lot of oil disappearing somewhere.

    Did you not have a couple of threads going about blue smoke and burning oil on here before Xmas. Was that problem sorted? It does sound a bit strange that you would have gunk in ur diverted valve. Sounds like a bit of investigation needs to happen to find ur problem.

    Morning mate sorry but I have been confusing..
    Yes buddy I meant the hockey puck ..it's gunked up really too much.
    I have done the n249 delete afew years back so all the mess on rocket covet is gone which improved throttle response..
    Don't know how to nip it onetime..
    No hose in the post today but I wait patiently.
    Ounce i get the hose I'll wonder how to plumb the catch can together..thanks for your help mate...

    Morning mate that's right I started investigating before Xmas and as off until now it had the head off valve guides fitted inlet/exhaust valves replaced,springs,stem seals,oil pump..I have also had the turbo on the bench which had slight play but was rotating quite freely.
    Hopefully get to the end of this mystery the problem I have I I only have 1 car so I don't have much time to work on the car I always have to complete whatever it is in like 1 day as I would need the car for work next morning..works 15 miles away or else I would trot it lol

    Blimey that's loads, did you get a compression test?
    Where's the oil going?
    Past the rings, combusted and through the exhaust?
    Out the breathers through the tip and intercoolers combusted and through the exhaust?
    Dripping out a leak?

    Stuart mate I know loads of work done in the last few months work was carried out by awesome gti they did a good job can't lie.
    They also replaced my cracked bam head as it had low compression so they took off head and found hairline cracks on 2 ports and also exhaust manifold was cracked so I gave them a used good condition1 and before the car went in with them I replaced t cam chain tensioner which I got from eurocarparts..
    There is a leak under the car but it's windscreen fluid from the tank so basically If I fill windscreen tank to the top it leaks half the amount so I keep under half full and got a window cleaner holts spray in the glove which I use almost everyday.

    Really mate the oil is making me so hot headed recently.
    Car went back to the repaires and they confirmed that all was still well with their work
    Their senior mechanic is a top bloke learnt so much from him I'd defo go there again and not just for parts either.
    All in all just put it down to age/luck buy I know everything should be running as it should after all the parts fitted
    .
    Hey ho I guess I've learnt to save money now lol

    Morning all..this morning got my silicone hose in the post so I now have all the bits for a catch can install.
    I've eyeballed the engine bay and sort of can tell where the hoses pop onto for the can but I'm not sure what to do with the hole
    That's gonna be left in the tip when I remove the hose that connects to the pancake valve..
    I have a can with a filter on top with no baffles and I do intent to vent to atmosphere..do I block the hole with a bolt??
    Thanks...silva bullet

    Put a bolt in the hole and a jubilee clip on it to hold it in place.

    You just put on another breather filter. The same as the one the catch can probably came with.

    What is the can like? 2 hose connections and a filter on top?

    If so, both hose connections are likely 'intakes', and the filter is the 'exhaust' of the can.

    One filter on top and one on the side and ur hose going in to the catch can if ur venting to atmosphere. I'll get a picture of mine in the morning and put it up if that would help.

    If your engine is spitting out a lot of gunky smoke those filters will block up and split.

    Hello everyone just a update on jobs done today in fact not very much done.I ripped out the ever so oily pcv pipes.
    As I have previously done the vacuum chamber detele all that needed removing was a hose that connects to the plastic elbow that comes out the block and also took off the hose that connects to the tip and then the oem junction which comes out the left hand side of the rocker cover.the pancake valve has also made redundant.
    Moving on in then placed a bolt in the oem tip hose which was left as I made the hose that connects to the tip redundant thanks for the heads up Hydros3. .scrapping is all done now I have to just install the can in the morning. .
    I couldn't heli coil dogbone mount hole as my crappy drill belive or not doesn't open enough to insert the fat round drill bit that comes with the helI coil kit
    So that's on the back back burner for now.
    On the sleering rack snapped bolts issue no luck at all the hss cobalt drill bit was a waste snapped after 3 second no bloody progress and it wasn't even raining..silva bullet

    I went through about £40 of drill bits trying to drill off one manifold to turbo bolt, you need the right amount of oil and start with small enough but not too small or they just snap. and that was from above - it's gonna be painful laying under the car, make sure you use good ramps and not the car balanced on axle stands etc.
