52 bolts holds all of the components in place. 15 o-rings sandwiched between the inner cover and the front of the block to seal in the oil. 3 of them are pressurized oil.
The 4cyl Subaru water pumps are driven by the t-belt, but they’re a walk in the park compared to this dumb shit. We replace a lot of head gaskets on them for oil leaks too.
And if your Audi needs extensive amounts of cash to repair, you deserve it.
Tech tip of the day: How not to brake wheel studs.
Have you ever put a lug nut back on and it started getting tight before it even made contact with the wheel? Then it won’t come back off, or destroys the threads if it does. WTF? It came off just fine the first time.
Whenever a lug nut is removed, hold it open end down and tap it on a firm surface a few times to remove the tiny metal chips. The metal dust collects inside the nut and will eventually destroy the threads. After years of rotations, inspections, and brake repairs, the threads naturally wear a little. Clearing the metal dust from the nuts will help them to llast the life of the vehicle.
DO NOT apply anti-seize, to anything. Ever. It gets all over my hands and your interior before i notice what the fuck you did. Plus it holds these thread-eating little chips inside the nut so they can continue to ruin your studs. if you own a jar of this junk, throw it away. The 1960’s are over.
Don’t get me wrong, there is a place and time for lubed studs. A lot of the older vehicles did not use acorn style nuts and the threads are exposed to the elements. This would be a good place for a silicone lubricant. However over time, if the nuts start to feel sticky, the lube is loading up with chips and it’s time to clean them and re-lubricate.
I also use lube after restoring to chewed up stud that had “dust” damage. Grind away the ugly threads and touch up the others with a triangle file. You don’t need all of them. Just most. ;)
Some steel wheel GM engineer decided to make the stud holes in the wheel too small, so when the nuts are torqued down, the tapered part of the nut gets crushed smaller. The nuts then come off hard, and can be impossible to thread back on. Removing the first thread or 2 from inside the nut with a tapered die grinder bit will cure the issue.
Enough of this shit for today. I’m going home to play.
