O2 Sensor finally removed and replaced!!!

Postby JusNoGood » Fri 22.06.2018, 17:40

Castle Coombe I had been trying to remove it for two week....well.....today I managed it!!

I tried....

Standard size 3/8 ratchet and O2 remove tool and penetrating oil
Standard size 3/8 ratchet and O2 remove tool and three jubilee clips and penetrating oil
Standard size 3/8 ratchet and O2 remove tool and three jubilee clips and penetrating oil. Ice.
Cutting off the end of the o2 sensor and trying with a socket. This time I broke the ratchet!
Turbo torch to heat it up. Standard size 3/8 ratchet and socket, penetrating oil and a pipe around the ratchet.

Today I got this puppy, https://www.amazon.co.uk/gp/product/B01 ... UTF8&psc=1

I've always found penetrating oil is a waste of time, even though it's much better for releasing stuff than WD40 which some recommend... :smt017

I normally use this stuff to give it a thermal shock - Freeze spray.. Get the exhaust/turbo hot as you can and then put a tube ( about 2/3 of toilet roll cardboard tube is good) and give the O2 sensor a blast to shrink it. Get the socket and a big shifter on it as quick as you can and out it comes out without too much protest ...

By coincidence I'm just refitting a Subaru engine and can't get the new heat shields back round the O/S manifold with the O2 sensor in situ ( the old ones were so rusty they just fell off). The sensor is on the O/S bank and being a boxer engine is accessed through the O/S wheel-arch. (Think M100 crankshaft pulley nut .. :lol: M100 O2 sensor is easy by comparison ). Engine is not complete so couldn't get anything hot so got out my 'big shifters'. Used a long 1/2" extension so I wasn't in the wheel-arch but it has a hole for a T bar.
Just happened to have kept a length of 1/2" spring steel bar from my up and over garage doors when I replaced them with roller doors and it's longer than my 1/2" shifter as well .. :bananasex: Boy that was tight, reckoned it was torqued to 'a grunt and a half'.. :lol:

The amount of uses some people recommend for that water repellent is quite alarming isn't it? :smt044

Has anyone tried the impact wrench that Lidl was selling on these hard to remove items like the O2 sensor or crankshaft pulley bolt ?

I tried an impact driver with a socket on it, Is that the same thing? Pretty sure that damaged the thread on the Sensor and in the hole too so I stopped using it. I think it wasn’t turning so my hitting it was just pushing the senor down

If that were true I would return the impact driver. It should only rotate with impact, not hammer against the socket axially.

I see what you mean. Wrong assumption on my part I think. I saw the threat on the O2 looked damaged. I had been trying all sorts to get it out like I said, so perhaps it was something else that damaged it.
