Swap help

Has anyone swapped anything else in their e38, had a engine build go wrong on my m62tu and been trying to find another motor and can’t find one for the life of me, looking at older range rovers and other bmw’s with the same motor, no luck.

Has anyone did a ls swap, or swapped with anything else, cost and difficulty?

If you guys have any info let me know,
Thanks boys.

FM Modulator

Has anyone any experience with installing a FM Modulator in their E38?

If so, how's the performance, and where exactly are you supposed to plug it in?

I have a pretty pristine e38 740il which has been serving me well since last fall. I ran an errand yesterday, came home and parked. Later I backed the car out of the garage and the STOP OIL PRESSURE warning come on so I stopped immediately. Turned the car off but I can still hear a electric pump on the left side of the motor running.

Disconnected the battery, checked fuses, tapped a bunch of relays JIC but as soon as I reconnect the battery (even a day later) the pump comes on and the car doesn't even attempt to crank despite checking the battery (less than a yr old) on the multimeter. Oil level is good and plenty of oil in the filter canister.

My guess is maybe the famous oil pump screw issues or a sensor but why no attempt to crank and is there anything else I should check for a quick fix?

Ok so, my e38 was crank no start when I bought it.

I’ve replaced fuel pump
Fixed relay so no the fuel pump is actually working
All spark plugs fine
EWS immobiliser bypassed by ecu ( I don’t know if that’s correct, but my bmw technician mate did it for me and now it cranks again. It didn’t before we bypassed it)

Anyway so I put it down to bad crankshaft censor as the cable was shot so I replaced it with a “prenco” one and it is still crank no start

ChatGPT reckons it’s because the car doesn’t like the Prenco censor and is telling me to buy a OEM or Bosch one

I might have missed some information here but I will reply back to all comments

I would LOVE some help as I’ve been messing around for ages😭

95' 30i.

Whole cooling system has been checked. The thermostat is new. The water temp gauge is in the center.

What could be the issue? Is this temperature normal?

I’ve been having nonstop battery trouble for years, but it’s finally time to replace the one I have. It’s leaking, and the car absolutely refuses to start after driving it only 2 days ago.

Does anyone have any recommendations (that are relatively common in the northern US)? Attached are photos of my current one. Apparently I should be using an H8 instead of an H9, thoughts?

EDIT: I’m pretty sure the underlying problem is a parasitic drain somewhere, but no luck finding it yet. Either way the battery is shot so it’s time to replace it.

I found a nice bimmer.

1998, 728, 200k km, 2nd hand, BMW original phone, looking really good.

Problem: for the past 4 years, it has not been used a lot (not because of a mechanical problem) and no service has been made during that time.

The seller claims he did an overhaul of the cooling system.

I'm a bit scared of the fact that it hasn't had any service for the last 4 years.

Car looking good, the driver's leather seat is a bit torn and needs to be fixed.

Seller claims no accidents.

12k euro

What is your opinion?

I’ve been having an issue with the BST (the device that cuts off the positive battery terminal) — it gets really hot. What can be done in this situation? I’d like to keep the safety function, but use a terminal from something else.

I got a set of new speakers for my E38. But the OEM speakers have 4 connectors while the replacement only has 2 connectors. What do I do with the two cables that presumably are passthrough to the tweeters?

Hey guys, I have a question. Ive been struggling with finding an engine oil cooler recently, got it refunded cause noone has it anymore. Its discontinued.

After doing some research, ive found out that apparently a full sized engine oil cooler radiator for my 740i was an option and didnt come in the base model. Chatgpt decoded my VIN and apparently i dont have that option. Does anybody know how to confirm that, and if yes what I need to buy, instead of the radiator. (my whole front except engine is missing)

So I have a leak coming from the 3rd hose connected to the oil filter housing and was going to replace the house but after looking into it, it would seem the previous owner possibly Jerry rigged a new hose on instead of replacing the line. The part number I found is 11-42-1-714-788 and just wanted confirmation that it’s the right part before I order or is I should just replace the current hose setup?
