Want to use MMO to clean neglected engine.Confused

My new favorite cleaning regimen (Best if done in the warmer months) is using 75% HDEO like Delvac 1300 + 25% MMO. I use the Delvac because it's usually the cheapest HDEO at WalMart. I run this for my full OCI @ 5k miles. Has done wonders for the varnished 1ZZFE I picked up last year. For regular maintenance on a neglected or unknown vehicle, I do this every other OCI.

Even before doing this, I frequently did 20-25% MMO for a full run (Every three or so OCI's). At 220K, my previous Subaru was spotless under the valve covers.

You get the extra cleaning abilities and stout additive package of the HDEO + the MMO. This makes for a great cleaning oil that is not too aggressive.

Also, considering tackling this myself (not a mechanic, but have done a lot of work... usually takes me 10x as long as a mechanic with 10x as much swearing lol). If you have any guides/service manuals on this that will be awesome. I may consider having a shop do this though.


This is not an easy job but doable if you want to spend the time.
You may want to have the dealer do this one, they have the latest revision of parts available and the experience.
I wouldn't trust just any indy with this unless they are specialist, it has to be done right.

First order is to get it properly diagnosed. Do the chains, all tensioners, water pump and any seals at the same time.
These engines are hard on oil, i have a late model with low miles but it crucifies the oil in short order. I use Mobil 1 0w40 in it for the last few years and its like a different engine.

It cleaned up nicely (got minor varnish on a 5K 5w30 OCI) and is smoother and much quieter.
Winter starting is no problem at all.
If you do decide to tackle this PM me and i will send you the info from the DVD.
 
In my old s10, I added half a bottle of mmo about 1000 miles before oil change with no problems. When I bought my used Silverado (unknown maintenance history), I used 1/3 bottle 5min engine flush (motor medic), followed the directions on the bottle, no problems. I'm gonna do this again for the next two OCI to use up the remainder of the flush using cheap dino oil. Then I'll start using the synthetic oil from my stash for one year OCIs (approx 5k-8k miles). Good luck w the timing chain
 
I'd personally do Auto-RX for 5k miles. Then do a 5k OCI with 20-25% MMO. Both using conventional oils. I'd personally then do a couple of 5k OCIs using Rislone engine concentrate and conventional oils.

Then go to whatever oil you want. You can try just doing oil changes but we have seen no evidence on this site showing just changing oil regularly, even short intervals cleans anything up. I did 5k OCIs with Kendall that is supposed to be a good cleaning/keeping clean oil and it still caused deposit problems on my Escape that I am now having to clean up.
 
I'd use a pint of MMO for the last 1,000 miles of your current OCI, don't worry about being 1/2 a qt over. Then do an OCI with 20% MMO, leave it in for 4,000 miles, just keep an eye on the oil level. Repeat if needed.

If you have mechanical problems MMO is not going to fix them. The nice thing about MMO is you can use it with dino or synthetic oils. It's cheap, easy to find, and it works.

What again is the non-mechanical problem the OP is having? I keep forgetting, or was there even one we know about?

He mentioned a cold start up rattle, that's probably mechanical, as Trav mentioned. MMO is not going to fix that. OTOH if the OP feels the engine is dirty, as he stated due to it not being properly maintained, MMO would be a good idea. So what he might end up with is a clean engine with a mechanical issue. That's better than a dirty engine with a mechanical issue.

Yes, mechanical problem (timing chain guide) that needs to be addressed, but I want to give it a good cleaning since I don't know the maintenance history. I usually give a thorough tuneup including cleaning carb and throttle body. Figure I want to start cleaning an engine as well to reverse some neglect.

I would do exactly what you're doing. Clean it up and do the repair if I planned on keeping the vehicle.
 
Would you guys believe that MMO cleans aluminum almost as good as EZ Off oven cleaner? One of MB restorer has a video showing this. Imagine using oven cleaner inside your engine to clean it but you get the same effect with MMO!

Do you have a link to this? I'd like to see if this was MMO in the sump, hand applied or what.

Just watched the vid. The key component is the abrasive scotchbrite pad, not the chemical used. He could have used it with water and it would be very effective.
 
MMO is good for everything. You can us it for:

-adding to engine oil to clean inside of motor, valve covers, pistons/rings and hard to reach engine parts, etc.

-add to fuel to lubricate fuel pump and clean injectors

-use as a cleaner and lubricant for firearms

-drink instead of metamucil to keep you regular

-use as a substitute for olive oil for better tasting baked treats

all kinds of things!

He tested it with zillion other chemicals; each one with scotchbrite; he has at least three different videos.

And he stated right in that vid it was amazing what anything could do with a little elbow grease. The scotchbrite; the ABRASIVE is the key component here, not the chemical.

Had he done it with a cotton cloth or something less abrasive we'd have a better idea of the effectiveness of the chemicals themselves, without the abrasive.
 
I have aluminum wheels in need of a good cleaning on my van. When the weather breaks I will give MMO a shot with a soft tooth brush. I have my doubts but I'll give it a shot if I remember.
