Rounded oil filter cap

[Lost1wing]

First oil change I did myself after the freebies, the drain plug was so tight I had to do the double wrench leverage hack to get it off. The oil filter cap was also tight but 24 twelve point did get it off. On the recommendation from a friend I have a extra filter cap I carry with me just in case.

One of the reasons for passing on those free oil changes.

This is the easiest vehicle to change oil that I have ever had in my life. How are people managing to bungle it?

I don't think they put the most qualified techs in the oil change bays. My brother had a job there once, he couldn't change a light bulb. Not all are bad, I'm just saying.

All this talk about torque wrenches and calibration......... the old-fashioned beam type needs no calibration ever if you simply take care of it and not run over it with your 4" lifted Jeep on 37 with a load of bricks in the back.

Seems to me that anytime those things get rounded it's because some gorilla before over-did it and the next guy had to use a 3/4" drive set and breaker bar to get it loose, or they aren't grabbing the correct wrench.
How can it be so complicated?
It's a Jeep.

Come change the oil in my 73 if you love tight spots and not even being able to see under the vehicle. Don't use a metal filter wrench, it sits 1/2" away from the alternator output cable and that's hot all the time.

I've got a drawer full of torque wrenches and a pegboard with 3 beam types and a special click-type for transmission use and even though I've done thousands of bolts and nuts over the decades and am generally extremely close to correct on many - I still check myself now and then, silly and a bit, well.......... not to.

Needs no calibration ->

The oil filter cap on the 3.6 can only go down so far as it is shouldered at the top, when I reinstall it I just go till it touches, it is usually fairly snug at that point. Where it has the o-ring it doesn’t need to be super tight, I also put a little grease on the threads of the cap every time.

Not planning on using my three free oil changes. I have always done the maintenance on my vehicles in my shop (thanks to the person with little experience hired by the dealership). I don't mean to stereotype, but I have seen it all from hoist/arm crushed fuel tanks to splash guards, ...and that is before they get a wrench on that drain plug.

Yep. None of them are allowed near my Jeep.

I have always wondered if temperature can cause different readings. If the torque wrench is 20f or at 85f, would the torque reading be different. All mine torque wrenches are kept at 70f.

Unless you are torqueing something on Venus, temp variations are nominal on most torque wrenches. Elastic modulus of most tool steel varies roughly 1% per 90F degrees.

Definition of tight.

Good to know. I can stop thinking about it.

I've torqued head bolts on Mercury, does that count?

I am sure there is probably some ISO calibration standard that will mention a temperature median.

In working aircraft for over 30 years, the only time temperature came up in torque calculations was not on the torque wrench but the item one was torqueing.

32 years here. Everything from torturing to cable rigging was 70f or the chart in the amm.

Working for Elliott TurboMachinery. The shop was maintain at 70F year round. Some of the equipment we worked on had a tolerance of 0.0002".
