2001 bmw 740il

[Antonilainez]

Hi I have a question regarding a 2001 BMW 740il that I wanna buy off a guy. So he’s selling he’s daily driver but said that it smokes like a locomotive (I’m guessing it smokes a lot) and that he had the timing chain guides, vanos and chain replaced. And It started to smoke three weeks after the repair. He said that he always kept up with its regular maintenance and made sure the car ran strong and kept it clean in & out. Soo my question is does anyone know how that smoke smoke can be fixed and if it’s fixable, if it’s fixable then I will be able to fix it. I really like he’s car a lot and I would like to buy it but before I do, I wanna know more or less how that can be fixed. So my question is, How can I get rid of the smoke issue on the car. And can I drive it off from he’s house to mine with the car smoking like that ? Please help any advice could help me a lot. Thank you for your time, I appreciate it.

Depends what's causing the smoke.........

Pcv plate on the back of the intake manifold would be the most common thing for smoking out the tail pipe, have him out one on

Do u have the link ? is this the one he bought off his neighbors and did the guides him self? if so, stay away its been for sale for some time and has already been looked at by people on here. I may be confusing it, but it sure sounds familiar..

**And about the smoking--everyone is quick to say the PCV or the CCV but in reality, the motor could have been overheated and it could have bad valve seals or worse.

If you are not mechanically inclined, or at least wealthy enough to pay a good mechanic, then stay away from E38.

+1 Johns01e38 has it right. If you can’t diagnose the smoke, don’t buy it. Your family will tell you ‘ I told you so’ forever

If you really want an E38 and you are willing to redo all of his work it is a nice car and the price is really not that bad. Does it smoke at start up or continuously? If it is only at start up you would be looking at the vapor recovery system. He should have replaced the turbine behind the chain guides that would be in the parts list. If he did not then you may have found your problem but would have to pull the front off the engine anyway. Second would be the feed tube under the manifold to the PVC, either or both could be the problem and should have been replaced.

If it smokes continuously do a compression check, broken rings? If that is the case you could get a used motor or if you are really ambitious rebuild that motor. Either way the car seems to be in good shape and if you go in with motor replacement in your head you won't get burned.

Only four things will make an engine smoke:
1. Too much fuel in the cylinders
2. Too much oil in the cylinders
3. Too much coolant in the cylinders
4. It’s on fire

Each of these could be simple or complex to address, at $1000 it’s not really a financial decision. If you want to make a driver out of it you’ve got plenty of good advice here. As for me, I wouldn’t make an offer until I did a leak down test, compression test and block test where it sits. If all those pass I’d consider an offer.

If the rest of the car is nice, then get it, with the cost of a new/used motor swap built in. What’s going on inside that motor is anyone’s guess, and other mistakes may have been made. Don’t count on it as a DD for quite some time.
