DIY Nightmare!
Posted: Sun May 27, 2018 6:30 pm
It never ceases to amaze me how an apparently simple job can occasionally go very wrong!
I thought that I would change the gearbox oil on our 13 year old 3-series. Simple enough to do, and the TIS shows just two items to come off (fuel filter cover and under body shield) to allow access to the gearbox fill and drain plugs.
Got the car in the air, took what I mistakenly thought was the fill level plug out, realised it wasn’t and tried to put it back in again. Except no matter what I try, the thread just won’t work. Nothing in the hole to block free movement and the threads look OK with a dental mirror (best I can do with that space). I’ve spent hours trying to get it to ‘bite’ and wind back in by hand - not enough room to more than an Allen key in the tunnel - including carefully checking the state of the threads but to no avail. It feels as if it trying to cross thread but it shouldn’t be. Aluminium on Aluminium so utmost caution needed.
Now had to bring the car back down off ramps and stands for safety and I’ll need to go to our local ZF transmission specialist, get them to recover the car and no doubt have to pay a small fortune to do what is probably a 30 second job with an appropriate tap to clean the thread. The gearbox will have to come out and I don’t have the tools or time to have a go myself. I can’t even get the car high enough off the ground to attempt it.
Today just wasn't my day! First time in 40 years of working on cars that I have ended up in this level of poo! So much for a simple oil change.
