#2. Disconnect Positive Battery Cable. 10 mm combo wrench. 318ti Only?

#3. Remove Battery. 10mm Combo or 10 mm Socket on battery hold-down bolt. 318ti Only?

#4. Unbolt Battey Box. Two 13mm bolts underneath battery. 318ti Only?

Battery + Battery Box Removed. You can see the two battery box bolts rethreaded so I won’t lose them. I think the 318i/is/ic has the battery in the back, so I guess you can omit steps #2, #3, and #4.

#5. Unplug and unscrew (Two 8mm Nuts) Ignition Coil Pack.



#6 Unplug Spark Plug Boots. Blue BMW tool in use. Just unsnap them for now.

#7. There are two nuts/bolts (10mm?) that attach the spark plug wire channel/heat shield to the valve cover. Loosen, but do not remove these nuts. I took these pics on installation, that’s why it’s so clean

My first roadtrip after the new plugs got me a new personal gas mileage record. 33.4 mpg. That was with numerous stops too 34 mpg should be no problem with a non-stop run.

Great posting! thanks much for the detail, and all the pics. In looking for a gasket set, I found the dealer is about 2-3x the price of the non-BMW parts houses. But, the oil supply seal is a dealer-only part, and not carried by the BMW dealers (I called east to west coast). It is a 2-3 day delivery for this $5.00 part. Be sure you have all parts before this surgery - my ti is now immobilized until I get that part.

Yeah, I'd get the new oil supply seal for sure. I contemplated not changing it, but after seeing how hard it was, I was glad I replaced it. Cheap insurance for ensuring a good flow of oil to the cams.

Yep, found everything I needed at PelicanParts.com. It totaled something like $51 with 2-day shipping.

Excellent DIY, just booked maintenance for this in our local workshop. And now i can collect all needed parts.

Oil Supply Seal: 11121247948, cant get this part anywhere in Finland cos M44 engine is very very rare here (didn't import it here much) so need to order it from Germany or Sweden, but without this DIY my car would stand in repair shop couple of days, so thanks ;D

Awesome write-up...just did this today. Your loss was my gain in pointing out to do the microfilters as well, so thanks for that!

Only thing I did badly was I forgot to put the really thin plastic baffle back inside the microfilter assembly. Is this bad? Haha...
