Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • T5 oil leaks

    Hi all,

    First real post on here so go easy on me
    I picked up a 2013 Multivan TDI400 (cfca) a few weeks ago with a dsg issue very cheap. Plan is for it to become a weekend camper for me and my partner once it's hopefully fixed up.

    I'm waiting for a vcds box before I tackle the dsg so for now I've turned my focus to the engine. It's done ~250k KMs so hoping the EGR cooler hasn't done too much damage (wish I'd googled that before buying it). I drove it home 60-70kms on a uvp with no real issue aside from the dsg not wanting 6th gear, engine felt strong.

    Upon further inspection I found a lot of oil on everything but particularly bad at the timing end of the top of the motor. Pulling the timing cover off revealed a lot of oily grime around the main camshaft pulley and the hpfp. I'm hoping this isn't a Hpfp fault as the oil doesn't smell like diesel, suspect it's tracked down from the top of the motor but confirmation would be appreciated.

    The rocker cover gasket was changed last September so unlikely to be that, cam seal is my next guess.
    I cleaned the motor down well so hoping I can track the fresh leaks now....

    Does anyone have any other suggestions for how I can narrow it down further?

    Pics aren't the best but oil definitely starts above the HPFP.

    I''ll start by saying that I am not familiar with these engines........but a cam seal seems like a likely curprit, but dont rule out that it could just be oil from when the rocker cover was leaking that was never cleaned up. You have done the right thing by degreasing and cleaning it all up and just keep an eye on it for the next few weeks.

    Looking at your photos the oil leak does not look fresh which leads me to think its possibly left over from when the rocker cover gasket was leaking.

    Not sure when the timing belt was last replaced, but seeing its been exposed to oil for a period of time it might be a good idea to get it replaced soonish once you sort out the leak.

      That'd be great if so, really hope so haha
      It seems fresh in a few spots but agree mostly old and no saying the fresh isn't just a puddle from before it was fixed. Suspect it hasn't been driven much since then before the gearbox went.

      Timing belt was done at the same time as the rocker cover gasket so 7 or so months ago. Should hopefully be good enough for a period of time and then will just chuck a new belt on to cover myself once I'm confident the motors solid.

      Hoping to do everything myself but will see how I go, have done timing before but with the engine on a stand so a whole different game haha
