How much Marvel did you add to the oil? With as much yuck as I think youíre describing, youíll probably want to change again in 500-1000 miles. Itís safe for gasoline and works wonders on injectors. If your 5w30 is 502-505 approved itíll be fine for the bmw. Itíll likely be fine anyway for a few short mileage OCIs coupled with MMO to clean the sludge out of the engine. It canít keep proper time with oil restrictions. As it cleans the sludge youíll want to change oil frequently for a few thousand miles as the filter will be bypassed in short order.

Which ground strap did you look at, engine one or exhaust? And you say ordered... you didnít order the expensive one right??? Off the rack cables from the auto store will do you just fine. I promise.

If you have gunk and grime on the engine and transmission bellhousing, itís because of a leak. It doesnít get there by magic.

6 oil 1magic stuff

Ill keep that in mind to change it pretty early.


I ordered just some generic **** from autozone but it looked to flimsy and junky. Im gunna go insulated like you were saying, itll just make me feel better. Engine.
I havent got to climb around the rear yet. Gunna have to back up on some ramps

Yes i know, i know, it got there somehow.
its more that I cannot track it bc I cannot follow a fresh trail. Its all just goupy, not exactly fresh goupy and caked on goupy.

Ah. Thatís a good safe ratio for MMO. Iíve gone as high as 20%.

Gotcha on the cable. Grab a cable from the battery section in whatever length you need. Actually grab two and add a second on top of the engine. When I get back to NY next week I can take a picture of how I ran mine.

I put a braided piece on the exhaust, itís about underneath the rear seat on the exhaust pipe (which is insulated from the chassis, just like the engine is insulated from the chassis without the ground cables). Canít have too many earth straps; your electrical issues will likely go away with proper grounds. The alternator canít properly charge the battery if the grounds are bad, either.

For cleaning, Brakeleen and a rag work fine. The best is pure gasoline and a toothbrush... use at your own risk. Grab the large bottles of CRC Pro Brakeleen. Engine degreaser used to work great until it got all eco friendly.

All the cables they had in the battery section were wicked long. Like 24-48 inches!
I found the rear earthing, it's in the same cruddy green condition as the front but neither are frayed/broken. Will still change those though.

Gasoline???

Yes gasoline, one of the best solvents out there. Iíve cleaned many a a sludged engine over the last 30 years. Gasoline isnít actually very flammable, despite the misconception.

Grab a 24Ē cable, cut it in two and crimp new eyes on the cut ends.

I'm not worried about the flamibility so much as the smell. Wouldn't it leave a greasy film?

Twas lazy, just ordered 2 separate cables

If youíd planned on painting the area, youíd need a final cleaning after gasoline, but to cut through built up gunk, a splash of gasoline in a can and a toothbrush is my go to. Brakleen or MAF cleaner work well but sometimes evaporate too quickly to dislodge thickened oil/grease/dirt deposits. All depends on what needs cleaning and where.

Look in Walmart's, etc. garden/lawn section. There are shorter ones readily available for lawn/garden tractors, often with lug-ends already installed on both ends:

Just wait until you decide to do the leaking oil pan gasket.

I went on the left side instead, to a cooler point on the power steering reservoir's mount. To do like the above's run from the jump-start ground connection on the right side, though.
