Take one car you have sold. Change the oil and job done.
Only, you know it won't be that simple!!!!! This is my W-reg, sold yesterday for a song. I had some engine flush in and needed to change the oil/filter one time before seeing it go. So, on jack, up go, under stands, down go, under sump, undo bolt, splosh oil, half done.
Now, under back, cartridge change, er no. Nightmare start!
Problem started with undoing the cartridge. Some numpty with a 16ft scafold bar had done it up, so when I tried to undo the 27mm nut, the whole cartridge started turning. And turning, and turning and turning. What happens is the cartridge housing is bolted from the inside onto the engine. the cartridge goes in the housing, the cap is screwed onto the housing. Without the cap coming off you cannot get to teh internal bolt and around you go all day.
So, off I went and bought a new oil filter strap, as I couldn't find mine. Brought it back, got under car to find the strap was soi big, it gripped the cap as well as the housing. Oh Bow locks. So, off again for a small chain one. Got back, doesn't grip the now slippery outside of the housing as the oil has been seeping out from the now broken seal.
In comes Marks DTM to offer some friendly help (after he stopped laughing). He has the mother of mole grips, so Off to his Mrs to borrow I went.Came back, canot grip - space small, and cannot get the leverage I want.
So, kept turning and wiggling the housing and it gradually got looser and looser until - 45 minutes later it came off.
Now, stage 2. Split the housing. I held the housing with the molies and used my mega torque wrench to try and undo, but as said it was done up by Geff Capes in a bad mood, so it wouldn't budge.
Picture the scene. Car up in the air at a funny angle, bonnet open, tools everywhere, oil spilt, car looking a bit dead, me trying to split the oil filter housing and some guy on his way to collect the car!
I gave it one last heave before giving up, and it moved. A lot of heaving alter and it was undone.
Now, I have got to post a pic of the cartridge!!!! No wonder the previous mechanic did it up tight! You don't want people to see this!!!!!!!!
Anyway, that done, on with the housing base, in with the cartridge, on with the top, in goes the oil and job is done.
And you know that noisy tapping sound? Guess what?
Still there.
