Yup, it certainly does.

I think that is one of the key points about how water/meth cleans as well. Consistent controlled delivery. Something that is hard to duplicate in any other method.

Hmm this got me thinking. We use "sure-shots" at work now. Could be useful in my application of the GM engine cleaner.

just to clarify, you would want to use SeaFoam Spray. SeaFoam Deep Creep is a WD40-type product and not intended as an internal engine deposit cleaner.

I think I meant to say fogger...

I have tried the seafoam "soak" twice and gotten minimal results, which is why I started reading this thread in the first place. I'm not arguing whether either one is effective. I'm just saying that RIWWP seems to have found the water injection at ~3k rpm seems to have more effect than seafoam. I'm not arguing about whether either one is really effective, I'm just saying that if anything could have an affect, it's more likely to be the water and not the seafoam soak.

This is why I said that I wish I had read this earlier. I wouldn't have wasted my money on trying the seafoam if I had seen that RIWWP found no change. I'm not going to "run out and do this". I'm doing research beforehand (like reading this thread). I may not even do it in the end.

The results of the seafoam soak wasn't really solid until this morning. General belief, yes, but something visible to show, no.

I bought the borescope off amazon for...$20? Anyone else can certainly try their own tests to see what happens.

That's cheap enough that I'll probably give it a go next time my oil needs changing. Can't hurt if done correctly after all
Plus I'd be curious to see how carbon caked my reman is after ~45k

Well you said, "I'll have to try this". I was just curious how you became so convinced that the water treatment was a worth while thing to do when the results shown don't prove this method to be worth doing at all.

Cliffjumper126

I'm not convinced it's worth while. I mean to find out if it is, that's why I said I wanted to try it. And because I enjoy working on my 8. Especially if I'm doing something that could be beneficial. Things only get "proven" when multiple people find evidence supporting it one way or the other. If nobody attempted anything because there wasn't any evidence saying it would help, then nobody would ever discover anything new. It can't hurt to try, especially since I do know what I'm doing with things that are automotive related.

Thanks OD.

While that rotor has carbon on it still, it's far better at ~50k with simply periodic W/M injection, than mine are at 15k. It certainly helps that particular argument.

olddragger

iTrader: (3)

yes --i bought it when it already had 45 K miles on it--put 15K on it myself when it blew( my fault).
It would have been better if I had it from the beginning.

the sides of the rotors were more impressive.

Karack

you guys are now seriously overthinking this.

subbed ... before I pull my engine for a rebuild, I am going to sea foam only one of the rotors to see what happens

9krpmrx8

iTrader: (46)

OD, the carbon build up on those rotors looks pretty normal to me The one rotor looks clean but with pieces of apex seals bouncing around in there that will happen.




And this is just OUCH. I forgot about that thread.

I had water injection done 6 months ago. The only notable change I has was a marked reduction in engine oil blow by. My catch can used to fill up easily however, now there is very little in the catch can after months of running.

I can assume that the side seal springs where freed up after the water injection.

olddragger

iTrader: (3)

Paul and Rick at Mazmart both told me that they where cleaner than normal. I believe Paul posted that also?
IDK--maybe that piece of apex seal flying around scrapped off a lot of the carbon---lol.
Maybe the carbon layers where not as thick as they normally are?

I do believe that water injection helps to control carbon buildup--i also believe that water injection does it better because it is injected while the engine is at wot. (hotter temps)
I see no downsides to it?
I will agree that it is questionable as to whether this de-carboning adds to engine life.
Who knows?

Here is a pic of my last engine torn down that was torn down only due to a failing coolant seal. It only had 30k or so and the engine still ran fine prior to being torn down but I did have traces of coolant in my oil so I pulled it before it had a chance to fail.

Notice the clean carbon free area where the oil injectors spray clean idemitsu from my SOHN

look a little heavy on the face front--but really clean on the sides?
Maybe yall have dirtier gas in Texas than we do in Ga--and that would be hard to believe?

I just want people to remember that I have forced induction and pretty rich a/f's.
9K was this before you got your turbo on?

copper showing?

OHNO!

its been a common find.

I thought Pettit built your engine? The thread seems to indicate Mazmart, or was that the engine that blew before the Pettit one? Me so confused ...
