    Low Oil Pressure

    Guest-only advertisement. Register or Log In now!
    Hey guys, posting for a friend as i come from the S4 world. His car recently started getting the low oil pressure light. When the car is started cold it blows a lot of white smoke out the back but there is no engine knock.

    Pulling the pan shows quite a few metal shavings and weíre trying to decide where to go from here. I have read quite a bit on the oil pump failing and causing these issues. Could the shavings in the pan be from the pump shaft? No oil leaking anywhere on the car and there are no blantanly obvious issues.

    Anyone have any ideas?

    I had the same issue and it was not the oil pump. Mind you, no metal shavings.
    Check the intake cam bridge. It has a check valve with a metal screen and some times the metal screen goes through the oiling system.
    I ended up buying a used engine from a 2015 car and swapping it.

    Itís the balance shafts there causing your oil pressure and the shavings done lots

    Low Oil Pressure

    The balance shafts seizes thatís where the metal shavings came from. Just replace the chains tensioner guides and balance shafts

    That is ONE possibility. You cant just KNOW that without even seeing the shavings first.

    Can this be swapped to a 1.8T setup? Where do you source your parts? Brands etc.?

    This is common on the b7 platform also. If you have the pan off already you should be able to see it

    You prob wonít see the balance shafts with the lower pan off but you will see the metal and brass shavings. The 1.8t is a similar motor but thereís to much different to make it work. The parts are cheap to fix your oil pressure issue I did a set off balance shafts last week and from Audi they were 480 for the set. There easy to do only hard part is undoing the water pump belt but I always forget about it until I have the chains off:(

    I believe the balance shafts are part of the oil pump assembly. In fact on the B7 forum where this is a common issue also the balance shafts are " cut" away from the oil pump gear to prevent this issue.
    This is a large job in my mind and when my oil pressure dumped I had it towed to the shop to have it done. Turns out low oil pressure was caused by a chain tensioner which self destructed and dumped oil pressure.
    To give you a general idea for the pan .. the subframe has to be dropped ( or at least loosened and pulled back .) So the engine has be supported. On the B7 there are two bolts that you access up through the bell housing which is tricky, and all this is just to get the pan off. Then you have to take off the lower and upper sump and the chain has to be removed.

    I am sure Quattro420 can provide more detail but I work on cars a LOT and I would not hesitate to have this done by someone else. If you don't have a lift I see this being a miserable if not impossible job.

    Yeah, it's a bitch!
    You dont have to support the engine, since the engine mounts stay in place, and you only drop the brace not the subframe. And you also have to move the steering rack so you can get to some of the rear bolts for the oil pan.
    Also, the balance shafts are not part of the oil pump assambly. The oil pump is on it's own chain.
    Balance shafts have their own chain as well and the 3rd chain drives the camshafts.
    I'm sorry to say, but there is a lot of missinformation in this thread.
    If you do decide to tackle the job yourself, make sure you familiarize yourself with the timing chain DIY. There is a few specialized tools you need.
    But so far, I dont think you were able to see what went wrong with your engine. Pulling the pan, might give you some idea, but there is a lot more digging you have to do.
    I'm not saying its not the balance shafts, but the cam bridge can be the culprit, the chain tensioner could be another one.
    I hope you get lucky and dont need a new engine.

    Like doc said your not gonna know for sure till you did in I donít think the balance shafts are very hard to do start to finish it takes me 4 hrs but my buddy does them in 2 hrs, I believe book time is around 9-11hrs. I always do new chains guides cam bridge and tensioner and new balance shafts. Iíve seen the balance shafts seize and stop the engine all together, the balance shafts like doc said donít run off oil pump they have there own spot in the engine block, the exhaust is balance shaft is just there and the intake balance shaft runs the water pump Iíve only seen the intake shaft mess up

    Thanks for clearing things up Doc . I wasn't trying to say the B7 was the same , just that on the B7 its a big job so would not hesitate to have it done by someone else if necessary. So imagined the B8 would be just as much of a pain

    Do you ever pull the engine when doing this job? Is it easier or more work?

    It depends what ends up being the problem. If it's a cylinder than it gets pulled. Most of the other jobs you do with the engine in.
    There is a lot of work to remove the whole engine and most of the bolts holding the engine to the tranny and mounts, etc, are torque to yield fasteners that cant be reused. So you are 100$ in bolts alone, leave alone labour.

    I know you found metal shavings in oil, but what other symptoms where there? What happened that prompted your troubleshooting?

    Front end is off completely at this point. Next is the pan. Symptoms were low oil pressure light, noise from engine bay at first and now there is nothing. Car starts and runs fine, blows white smoke for about 15 seconds on startup than it clears up. Going to scan with VCDS shortly.

    Figure anything else out? How does the coolant and oil look? Anything out of ordinary on the oil cap?

    Again, best of luck!
