What did you do to / for your E53 today??

[EODguy]

Nope. Transfer case motor destroyed itself, but the gear was pretty good looking. Not sure if it's possible to basically "slug" the motor by stopping emergency style like a combine harvester. Cost me 260 USD for a new one on short notice.

I've had a fuel tank purge valve fault code for years and always got a whiff of fuel sort of around the back of the car too. So yesterday I thought I would replace the purge Vale. Of course the pipe connectors were all brittle and broke so a bit of clever engineering came into play there.
At the same time I noticed the coolant temp sensor was weeping around the thread so that came out only to reveal that the pump body surface where the crush washer should seal was all rough and pitted - like it had never been machined in the first place.
So again I had to do a clever bit of gentle filing with some abrasive paper and a flat edge to get that right.
I haven't ran it yet so I hope it stays sealed.
Another camshaft position sensor is on the way as I ordered the wrong one last week.

I've run 93 octane in this thing since I bought it.

Last fill was 87 at about 1/4 full. It does not seem to run any worse. No knocking.

What grade US fuel do y'all run? I get gas at Costco, and a few times when it was near E I did half 93 and half 87. Ran fine. So I've probably been setting money on fire with the 93.

I buy my gas at Costco. Its much cheaper than the other stations around her. Highest octane here is 91 most everywhere. You can find 93 at a few stations. They call it "race gas".

The engine is designed to detect the knock from predestination, the result is usually less power.

With my m54 i lost enough mpg with 50/50 87/93 that it wasn't worth it. The one time i put in 87, (out of fuel due to a stuck fuel float), i forgot to tell the person bringing gas to bring premium, the engine misfired on the initial launch to freeway speed and i got to limp mode to gas station.

Snort. My Costco has 87 and 93. No in-between.

There was a Shell station where I used to live in GA that sold 100-octane "race gas" for almost $10/gal. Sorry, the closest race track was about 60mi away...

I really cannot sense any difference. But I also don't drive this old bitch hard either. I need it to last a few more years.

I did of course use full throttle to get to speed on 70 zone expressway. My suspicion is that mid grade or using bottle of octane boost can get the job done. I've seen them on sale for $1

This weekend I changed the rear wiper motor because the rear washer has not been working for quite some time. I think it was 80stech said there is a chip in the motor package that gets burned out so the washer pump for the rear won't come on. Got tired of not being able to wash the rear window. Well I got a be careful what you ask for . Washer works now, but it also squirts some fluid every time I shut off the car. Not to mention it covers the rear of the car in washer fluid which doesn't really blow off. I should have known better. This pump is going back and the old one is going back in.

Got notified that a 2006 hit the local Pull-a-part this morning. Went before a trip out of town. M54 automatic, pano sunroof that was intact and closed, low spec, had nothing I needed.

My ‘01 has a belt or pulley or accessory squeak going on, every rotation not constant. Need to check that out.
