Thumbs Up Re: How-To: MMO Piston Soak + Oil Change

Awesome write up! I have mine soaking right now. My plan is to soak it for just 3-4 hours then turn it over to clear it out. Then I'll immediately soak it again over night and hopefully that will loosen it up a little more than just one soak.

I have a 6 hour drive coming up this weekend and don't want to worry about topping off my oil on the way there and back. I already put on a new valve cover and cleaned the EGR. So far there has been quite the noticeable difference.

Default Re: How-To: MMO Piston Soak + Oil Change

I started soaking a car last night using Kreen. 2oz per cylinder. This morning I see the two front cylinders dry. The other two still have some Kreen. Can't exactly tell the level though. Does that mean anything? The car runs great, just notice some light smoke at random times from the exhaust. Most of the time no smoke at all. I put back 2oz in the empty cylinders and topped up the other two. Will check back tonight. And what's the point of an oil change right after if the stuff is supposed to be added to the oil and driven 1000 miles anyway. I just changed the oil before doing this.

Point of the oil change is that its a solvent that will greatly degrade the lubricational properties of the oil I wouldnt drive more than 50 miles with it in the oil.

But you're SUPPOSED to add it to the oil and drive 1000 miles before a change to clean out what the piston soak missed.

I don't see how anything in the crankcase would help clean the oil rings (other than good quality oil helping _keep_ them clean in the first place). The idea of the piston soak is that it indeed _soaks_ the rings; lets whatever you use do its thing over time. Any additive to the oil, with the engine running, the pistons are moving too fast for any additive to work on the rings. And if this new stuff is considerably thinner than the oil itself, I would not leave it in for as long as 1000 miles, as it would dilute the lubricating capacity of the oil.

As for the Kreen draining down from above on two of the cylinders, I've read/heard different things about that. One take on it is that if it drains down, that's actually a good thing; it means that oil ring is _not_ coked up, just leave it. And let the ones remaining soak a little longer.

What does the MMO soak accomplish? ... and if I perform one on my SW2 with 130,000 miles on it, what results should I expect?

It should help free up any stuck piston rings you have. Results could be slightly better performance and less oil burning.

Sorry to bring this back from the dead, but I assume the process is the same in a SOHC?

Would it be safe to say this process works just as well, if not better, by replacing MMO with Seafoam?

I would imagine that an oil change is absolutely necessary after, say within 20 miles or so.. and the process would pretty much be the same with an SOHC its just the plugs are in a different location.

Much thanks and a great thread!

It's actually much easier to get at the oil filter through the passenger side wheel well. Remove the wheel, then pop the two expansion plugs on the rearmost wheel well shield and remove it. The oil filter is right there and easy to turn by hand or with a wrench.

I've been doing it this way for over 20 years and highly recommend it too.

Several years ago I started using one of these flexible green funnel things pictured below to keep the subframe and such below the oil filter from getting dirty with the old used oil. The oil that drains when the filter is loosened goes into the little trough (mostly), and then it hits my flexible green funnel thing which catches nearly everything and directs it toward the basin on the floor under the oil pan. Afterward I wipe the flexible green funnel thing clean. It still has the first shape I made, and by rotating it under the axle to get it in and out keeps the shape. It works well. Just a little pricey. Mine is the older style with lead rather than aluminum inside.

Usually as the filter comes off the engine all the way, a bit of oil does go on the axle but it rarely goes on the rubber bellow boot. I suppose we could be creative with the flexible green funnel thing, or maybe even a piece of aluminum foil, to keep the axle clean...


We can buy these from several places. Here is the manufacturer's webpage for it:
