BMW M60 Engine Tune-Up – 2 Hours
A BMW M60 engine tune-up is a relatively simple procedure that even the beginner “Do it Yourself” mechanic can handle with ease.
Tuning up the M60 four liter V8 is really easy. Nope…we are not losing our minds here at the Repair Guide. Putting a new set of spark plugs and coil packs into this compact V8 truly is a simple repair. In fact we had forgotten how simple and straight forward a BMW M60 engine tune-up is, only to be pleasantly reminded while putting this article together.
The M60 4L V8 was BMW’s first eight cylinder engine in almost a quarter century. It was the power-plant in BMW’s premier lineup of luxury sedans and coupes during the ’90’s; the E32 530i/540i, E34 730i/740i, E31 840ci, and E38 730i/740i cars.
Putting a new set of spark plugs and coil packs into this compact V8 truly is a simple repair.
This eight cylinder work horse of the early to mid 1990’s was ultimately replaced in 1995 by the M62 4.4L V8. Notorious for reliability issues due to it’s Nikasil lined engine block, the M60 has been unfortunately black listed among many BMW enthusiasts. But many reliable cars still remain in service with M60 engines in them, and with proper care and maintenance they should be around for a long time.
The price of coil packs and plugs for the M60 engine is relatively cheap. Good OEM coil packs can be found for around $50-$70 a piece…plugs for about 5 bucks each. You should be able to do the whole tune-up for under $600, which is less than half than what you would expect to pay at the dealership. When purchasing coils, make sure they include the rubber connecting boot. The BMW Repair Guide always suggests using a good OEM brand for the coil packs…stay away from cheap “generic” or unknown branded parts (if in doubt, purchase our suggestion below). If the price is “too good to be true”, then you are probably buying an inferior part that could damage your engine.

Tools and Supplies
10mm socket wrench
Spark plug socket 5/8″
Torque wrench – medium range
- Use a socket wrench to disconnect the negative terminal from the battery before starting this repair. Always cover the terminal with a clean rag to avoid accidental contact during the repair. If working on a vehicle with 2 batteries (8 series), disconnect the negative terminal from both batteries. ALWAYS disconnect the battery(s) before performing any type of mechanical repair, especially in the engine compartment.
- Remove the four 10mm nuts anchoring the top engine cover. Remove cover from engine bay.
- Remove the two side engine covers. The covers are held in place by two 10mm bolts.
- Unclip the electrical connector from the coil pack on cylinder #1 by pulling up with your fingers. Remove the electrical connection from the coil pack.
- Use a 10mm socket to remove the two nuts anchoring the coil pack to the engine.
- Remove the coil pack from the spark plug.
- Use a ⅝” spark plug socket and extension to remove the spark plug.
- Prep the new spark plug by putting a thin layer of anti-seize lubricant to the threads of the new spark plug. This keeps the spark plug from seizing to the cylinder head and allows it to be easily removed during the next tune up.
- Reinstall the new spark plug and torque to 25Nm (18 ft-lb).
- Add a dollop of dilithium grease to the coil pack boot so it can be removed easily during the next tune up.
- Repeat for other 7 cylinders.
- Reinstall engine parts following steps 1-6 in reverse.
