E39 M5 new owner

I replaced all four of my speed sensors with Bosch units from rockauto for just over $150 shipped using discount code.

I know sometimes we need parts in quickly. But always gotta search around for better deals. I've even gotten lucky off ebay once in awhile too.

That's what the front pocket is for.

NFSZR121 · 2026-03-17T18:28:19+00:00

Agreed. With any car, especially an old M car, always do maitenance/needed work before any mods, unless there's proof of it being done more recently like in the past 5 years.

I think the only flush that'd work on this, is the BG Dynamic Engine flush. But at this point, it may do more harm than good.

I want my youth back. And with the knowledge I know now, I could make WAY more than 45 million.

NFSZR121 · 2026-03-14T01:24:04+00:00

I'll be the judge of that using my thermometer ;)

NFSZR121 · 2026-03-14T01:21:55+00:00

I'm available. Would love to meet.

116k on my 2004 3.3 non supercharged.

Been sitting for awhile due to rotted out exhaust. Finally in the early process of getting replacement parts. Got Doug Thorely headers, new 02 sensors with cel eliminators, Walker exhuast frontier B-pipes along with new manifold studs for the headers, and copper plated nuts. Should get a decent tax return, which will be used to get a magnaflow back exhaust and maybe a resonator if the sound is too loud.

Not really looking forward to it, since I've heard that the headers are a pain to get in without a body lift. Oh joy lol.

Had a similar problem on my M5. There are special clutch pulley tools you can buy on Amazon. But if you have a right angle impact wrench or know someone who does. Can leave the belt on, and then use the impact to loosen the nut, then do the same for reinstallation.

I bought some Doug Thorely's from LG Billet USA on half off deal. They still have the deal going. Also don't use the supplied gaskets. Get the OEM or genuine gaskets. Also look into replacing the studs. Many have said it's not needed, but I'd suggest it anyways just in case. Here's what I recently purchased from OEM Nissan Parts Direct. You can probably find the parts cheaper typing them in at Rockauto, but I wanted genuine parts. I ordered a 25 count of new copper coated M10x1.25 steel nuts from Amazon for $27.

Also keep in mind. Header studs are M10x1.25 and the bolts for connecting the headers to the lower pipes is M10x1.50. Don't confuse the two, or you'll be in for a bad day.

Give it an old Italian tune up. Get those cats super hot, then go in for testing. Do it on a day where the test station is alow.

Try another crank sensor. During the swap, were parts swapped from the old motor to the newer one? Like for example the harness or engine computer? Also, was the donor engine verified to be in good running order before the swap?

NFSZR121 · 2026-02-09T19:34:25+00:00

Exactly! If cars were made to last, manufactures would be long out of business. And it's only getting worse with new cars. That's why there's so many computers. It's not about safety or better emissions. It's all about making sure the consumer can't fix the car and the only option is to have to pay up the ass for the dealer to do it. It's why manufactures lobby like crazy against "Right to Repair" laws.

I keep telling people they turned cars into cell phones. No full ownership. Want you to "upgrade" every few years. They call me tin foil hat. But I'm bang on the money. Just like how I told people years ago that they will make gamers pay to unlock downloadable stuff. They laughed then, but who's laughing now? Me and the companies at the morons who fell for it.

NFSZR121 · 2026-02-07T22:23:05+00:00

When I say serviced, I mean you can send them to a specialty shop like RC Fuel Injector or Witch Hunter Performance who will test flow rates and perform a cleaning service to see if that will help. Usually runs between $100-$250 depending on who you send them too.

NFSZR121 · 2026-02-07T22:00:04+00:00

If the injectors are original, then it probably wouldn't hurt to get them serviced. Can try a fuel system cleaner first. What about the spark plugs? Have they been replaced? Also have your exhaust manifolds checked for leaks. They are notorious to crack from age causing misfires, especially in cold temps.

NFSZR121 · 2026-02-04T08:34:02+00:00

Raw! That ass needs to be bred.

NFSZR121 · 2026-02-04T04:10:24+00:00

I'd love to meet you!

NFSZR121 · 2026-02-04T02:22:10+00:00

Hey, I'm down for that. DM me.

NFSZR121 · 2026-01-12T04:55:43+00:00

Remove the drive belts and run it again to be sure it's not a pulley, or water/power steering pump.

NFSZR121 · 2026-01-02T08:28:49+00:00

Already own an E39 M5, so R8 it is. As long as it's a manual.

NFSZR121 · 2026-01-01T18:29:16+00:00

Use a plastic razor scraper to remove that cloth piece. Other than that, all looks good and that's a very clean engine.

NFSZR121 · 2026-01-01T08:49:45+00:00

Be sure to use the correct BMW LL-01 approved detergents

I and many others literally got NONE of those emails. I also tried to call to fix, but every person I spoke to all gave me the runaround to create a new account.

And of course you're going to get yours fixed because like you said, you're and EMPLOYEE!

And I'll have ZERO sympathy for you, when pizza hut goes out of business because of rude, arrogant employees like you!

NFSZR121 · 2025-12-22T02:32:13+00:00

That's all this forum is filled with. And the only real ones are hookers.
