O2 sensor

[ncinirator]

Slid under the 95 Caprice 9c1 to work for about an hour. Went to remove my O2 sensors, last night I soaked them in some PB blaster.

Started struggling and took a real good look and it looks like the sensors are welded on there! Or is that just how they look after spending time down there?

If they are welded on there WTF am I supposed to do? Take off the piece and walk into a local muffler shop to have them remove it? The passenger side looks welded on too.

That looks like the O2 bung welding

Most likely siezed. Could try hitting it with an impact if you can do the extension dance to get it in there, or run the car so its hot then try, or heat it with torch.

Or buy hooker 2451hkr headers and a pypes x pipe and enjoy the noise

Well, I have a 30 gallon home depot air compressor but no impact gun so I guess I'll have to hit up Harbor Freight.

I don't have a torch... How about a heat gun?

I don't like noise it gives away my location, intention and direction.

But like a dumb-ass, I removed the manifold before fiddling with the O2 sensor, thinking it would come off with no grief. The pipe is up in air thanks to a jack-stand.

If your wondering, yes I forgot it hangs from the manifold, so when I got the last nut off I was reminded by the fact after the pipe crashed into my balls & face..

You may find that a little propane torch used for plumbing may help. Good luck finding an impact at HF that will have enough humf to work. You may be able to go to a Pawn shop and get a decent impact gun for a reasonable price. Wish you the best of luck

Crap man, I totally didn't think of that, i have 2 propane torches laying around somewhere.

I know Harbor Freight sells China stuff, I do not endorse them at all when it comes to things that get the job done.

I didn't think about the pawn shop route either, I walked into one once and didn't like the feeling of it. Had to go home and shower.

I'll probably seek an impact from HF or craftsman.... Maybe home depot or Lowes.

It didn't make sense for the exhaust pipento fall in my crotch after I un-bolted it from the manifold. Last night I noticed that its bent away from, and not hooked up to the holder thingy. The passenger side is though

Looks like the previous owner got flim-flamed on an exhaust repair or took a stupid short cut to hanging a new pipe.

Harbor freight tools are like disposable cutlery. You can wash them if you have to, but why not throw it away and buy more??

I took advantage of the black Friday sales. Scored a craftsman impact gun and a bunch of other stuff from 30-50% off!

Today I'll break off the O2 sensor to get the impact on it and get'er done.

Oh man. I wish I had one. I had to try bracing in every way and use a 3 foot breaker to get mine off. Should have ran the car a while first or something.

Man, you guys poopooing the HF stuff need to do your homework. Their earthquake impacts are cheap at around $100 or less and pretty well regarded. Lots of guys using those professionally with great success. I have personally used them when a Snap On MG725 wouldn't do the job. First hand experience. Granted not everything HF sells is worth the money, but the earthquake line of impacts certainly are. The 1/2" one will give any other far more expensive 1/2" unit a run for it's money if not flat out doing better than it. Anyway......

I may be wrong but that sensor looks welded in. I say that because if it was bolted in all the way, the lower pic shows a gap between the head and the O2 bung in the pipe. That gap shouldn't be present if it was run in all the way and seated. That looks like it's been welded in place. I certainly hope I'm wrong though.

With part of the 'crotch buster' removed, I took my craftsman wrench & a hammer to it. 4 good hits and it moved. I had to beat it off part way(no homo... Not that there is anything wrong with that) and then I could turn it the rest of the way.http://uploads.tapatalk-cdn.com/20161201/06c3db272380f09b681f2121cd21e153.jpg

Kick ass man! Glad I was wrong on that one.

[harner]

Glad you were able to "beat it off." It did look pretty well sealed on there so I'm surprised.

Also noted on the HF stuff. I rarely have issues with their stuff anymore, but was always concerned about their impacts. Now I know what to look for if my Kobalt 1/2" air impact ever craps the bed.

[ncinirator]

Pulled the driver side head & cleaned stuff up in prep for the gasket.

I took a whit wire wheel & die grinder to the block. Must say the HF air grinder did the job well.

But I noticed that the old gasket seemed to have left an indentation on the block. The FSM says to file down any gouges or searches, not sure if I should try and find this out our not.

Any one here got any input?http://uploads.tapatalk-cdn.com/20170110/c7596ccac53052908d77d0c340bd08c9.jpg

Leave it be, most gaskets you shouldn't have even hit it with a wire wheel because now the ra on the deck surface is more uneven. If you try knocking that down more, you may screw it up and need block decked

Shist, hope i didn't eff anything up.

Better than what you did, yes, lol. I'm very much a razor blade and brake clean person. Time consuming, but I don't have to worry about the abrasive dust in my bores then

I usually just run a fine flat file across the surface after I've got it clean. It's not enough to take off any material unless theres a high spot, in which case it needed knocked down anyway. About the only thing you will be removing off a block deck is any carbon from around the wire ring area and an occasional small ding around the edges if you got a little rough during handling.

My dad passed away a few weeks ago. He started to decline not long after I got him in a decent home.

Kinda kicked the wind out of me. I haven't had the motivation to pick things back up. I guess there's no way to get it done but to just get it done.

Anyway, I should be having some updates soon, and will be tapping y'all for info.
