But coils may be more critical on the S65 because knock control is done through the plugs. I would like to know more about the role of the coils in that and whether added resistance and/or weaker coils due to age or heat or use/mileage has any effect.

The car has 170k miles on it. I doubt ignition coils are going to be the cause of whatever catastrophic failure occurs on it. |

Certainly, if after 170k miles of use, if the original coils, they would have wear and tear from use and repeated heating and cooling cycles. If I remember correctly, the OP stated there was a low rpm issue which coils can contribute to as weak spark can cause this. Every used car in buy gets a tune up and every maintenance item addressed to ensure longevity. To date, I haven't had a catastrophic failure and all of them are going strong. This car may have a long life ahead of it since my first 3 series was well over 300k when I sold it.

For the spark plug job.
Is the 16mm spark plug socket available at Harbor Freight/ auto parts stores? Or is that something I should order from ECS tuning? I have a receipt receipt from bmw. Stating that the car needs plugs. That was at 173k. Definitely will be doing coils. But would like to try doing plugs first. |

If you are doing plugs and plan on doing coils soon, I would do both at the same time so you do not repeat most of the labor. As suggested above, have a few extension options so you can fit rears where clearance is tighter. If you do not have a rubber lined plug socket that grips the plug, a magnet stick will help you pull the plug out of the hole. The coil tops can break if you are not careful and even when you pull them out. They are hollow plastic and can’t take much prying. There are various tricks people use and one person even designed a special tool just for these coils though I have one and don’t think it is that great.

I have found the bent coat hanger method works the best for getting the coils out. I also find that twisting them all a little before pulling helps. I find that getting the PS reservoir out of the way helps - and you of course have to remove the air-box. No need to remove the plenum.
And as pbonsalb implied, it is much easier with a good plug socket. 6 of the 8 plugs are easy. The back 2 can be entertaining but for a V8 in a small car, it is really quite easy to do.

You did the right thing replacing the bearings, hats off to you. I'm not surprised at the condition given the mileage, but that is definitely NOT normal bearing wear.

I’m glad it’s done. Hopefully I can run it until 250k before a rebuild. Also, should I be keeping the RPM under 3k? Atleast until I do the o2 sensors and plugs ? I need an alignment and then diagnose the rear and sway when turning left only Last edited by bmwpower603; 06-18-2019 at 06:15 PM.. |

1.) Start the car and allow cold start cycle to finish, it's only about a minute. 2.) Begin driving as normal but don't push the car crazy hard or anything and keep the revs to about 3k RPM until the engine temp. needle hits that first indicator dot, which is appx. 165 degrees. 3.) You can then gradually increase revs up to 4K and 5k RPM and so on as the engine temp nears full operating temp of appx. 210 degrees. 4.) Once the car is up to full temp - Fire at will and enjoy! Yes, this is a little absurd but this will allow time for the super thick 10W-60 oil to properly works its way through the engine to achieve sufficient lubrication hopefully without causing any damage or premature wear along the way. |

I’m so happy to have done this.
The car is amazing. And real M motorsport. Unlike the new m3 and m4. Which have same internals as the 340s, just beefed up. It was either this. Or an e36 m3.. I say this |

For sure the E60 M5 and E92 M3 are the real motor sports experience. I remember my 1st test drive in my car before I bought it. With test pipes and OEM exhaust mod I was sold. These cars have such a soul you can feel it. They love when you push them hard. Way more pleasurable than my old LS3 vette.

OP, thanks for sharing! Good sign that the bearing can wear and tear for a long time before they potentially go boom.
Would you mind posting here as well mate: https://www.m3post.com/forums/showth...253084&page=51 Thx |

which 3 series was it and how much did you end up selling it for with 300k+ miles???

It was a 1982 318i coupe. If memory serves me right I believe I got $1000 for it when I sold it.
