Adding Seafoam to the Oil?
As you might know, I've been doing a lot of research on how to possibly clean out the oil passages in my '78 project, and the subject of Seafoam keeps coming up but mostly in the gas tank; anybody use Seafoam in their oil, and how'd it go? Is it worth it? I've read it helps...I've used it in gas tanks, but not the oil.

step #21 - 50/50 recipe of engine oil and transmission fluid to flush the engine. Seafoam an internal engine lubricant ?
Automatic transmission fluid is a lubricant, and keeps the internals of an automatic transmission and lines and oil cooler clean, as well.

Re: Adding Seafoam to the Oil?
Lots of guys do it - I don't. I don't want solvents in my crankcase. I've had great results with the ATF/ oil mix. Doubled the compression on an old CB350 twin. I cleared up a tapping lifter and clogged oil sending unit screen on a Sierra 1500. I've cleaned out a half dozen other engines the same way. Just let it idle as long as it will without overheating and dump it.

Re: Adding Seafoam to the Oil?
Interesting! in practice you put this mixture 50 engine oil and 50 ATF, and then when you run the engine, how many minutes? then I let it rest for one night, more than one night or is it just a few hours?
forgive me all questions, but I'm curious to learn.

Re: Adding Seafoam to the Oil?
Seen a guy drain the oil and put diesel in, then run it for a couple of minutes "to flush it out". No idea if it made any difference, but that was in a CB450. I would not do it to a plain-bearing engine.

Re: Adding Seafoam to the Oil?
Yeah, I was just curious. When I did my '75 I did the Randakk thing, and it did smoke some, but not a lot, and went away pretty quickly. I have both on the shelf (Seafoam and ATF), but I'd never done the Seafoam. Thought I'd ask and see if there was a favorite.

Re: Adding Seafoam to the Oil?
On your 78,
I think that I would use cheap oil and change it a couple of times.
Since you are trying to get the rust particulates out of the engine, I'm not sure
how effective solvents would be at this point.
The goal at this point should be the same as an oil change.
Run the engine, get the oil warm and flowing,
suspend the contaminants in the oil, open the drain and let them get carried out by the oil.
The sludge and crap that has accumulated in the internal nooks and crannies could be cleaned out
later on using seafoam, mmo, atf, etc. after the majority of the rust particles have been removed.

Re: Adding Seafoam to the Oil?
I've used a high detergent diesel engine oil on a 49 chev before, 3 flush and change, also changing the filter each time.
I sure don't know if that would work well on your 78? Seafoam is kinda corrosive ...haw?!
Randakks ATF method might be a plan? Would seafoam do harm to seals and gaskets might also be a question, since they're probably old and brittle.
Just a thought .

Re: Adding Seafoam to the Oil?
Use seafoam in both gas and oil. If you put it in the oil, easy miles, no more than 100 before change..

This works for me … 'new' bike with lower mileage doesn’t seem to benefit as much as the older, high mileage bikes did.

Re: Adding Seafoam to the Oil?
My very first car when I was 16 was a Rambler American that my great uncle gave me. 4 cylinder flat head, three on the tree. The car was about 45% bondo. It used a little oil and I was broke and it was down over a quart. I put in some high detergent diesel oil that Dad had around for his tractors. That oil cleaned that old four banger out so much that it began smoking and using oil at an alarming rate! That high detergent oil cleaned out the sludge which was probably the only thing holding oil in the engine. Drove that car for a few months and on my way to a high school basketball game attempted to ram through a snow drift, got stuck of course. Found out the impact caused the right front A frame (unibody car) to break off and the wheel assembly was lying at about a 45 degree angle from vertical in the snow. That was the end of that vehicle. Your mentioning high detergent diesel oil reminded me.Francis wrote: ↑Mon Nov 28, 2022 4:56 pm I've used a high detergent diesel engine oil on a 49 chev before, 3 flush and change, also changing the filter each time.

Re: Adding Seafoam to the Oil?
@ sagebrush
Lol.., that's really good story/memories , I bought that 49 chev 1/2 ton from a farmer which I built a dugout for, asked him if it ran, he said well, you'd have to put gas in it and a battery (6 volt) then probably will. It did!! drove that thing for a whole year...sold it so I could get another bike. Still see it once in a while, it's all re-done, the guy has a 350 in it, brings a smile every time I do see it!
