well poopy I put filter oil into the carb and then realized what i had done and then put in some afterrun oil and worked the throttle a lot will the filter oil cause any harm?

MAMMOTH TOUGH

Dont put WD 4... well too late

MAMMOTH TOUGH

i should have been more descriptive but i was implying to take the carb off and clean it Realy well a lil wd then rinse it with fuel or better yet ethanol/methanol sorry for being les then in depth!

alright i'll go do that so as not to get gummy but on the t-maxx engine CD they used WD-40

What kind of Filter oil was is and How much got into the engine?

My concern would be Not what is causing the carb to be sticking, the WD-40 will fix that, but is that filter oil going to be disolved by the glow fuel when you run the engine?
I'd take a few drops of the filter oil and add add a little fuel and see what happens when they mix, If the Glow fuel doesn't disolve the oil, you have a problem. What ever happens in your "test dish" is what is going to happen inside the engine.

You might need to break down the intire engine, clean and rebuild

I would have to agree. It depends on how much filter oil got into the engine itself. I have extensive experience with using filter oil on motto cross and drag racing (blower filter). The problem with filter oil is it is designed to chemically dry out once it has been applied, it stays slightly moist and very sticky and gummy. Denatured alcohol should help remove it. Take the backplate off and spray a decent amount of alcohol in then work the bearings real well to flush out the oil. The key to salvage this engine is patience! It'll take a little bit of effort but it will work.

lol, omg, thats funny, sounds like engine break down to me.

sovietspyguy

shouldn't be that hard, i wouldn't say engine breakdown, just take off the backplate and the carb and rinse it out, it's pretty simple.

thats what i meant.

Flood the beater with WD-40 and After Run oil..Over and over and over and over!! While turning it over...over and over and over..you should be straight.

sovietspyguy

i hope you don't mean with the backplate and everything on. it'll just flood. if it's really a major problem just take out the backplate and rinse it. Better safe than sorry, and backplates aren't all that hard to remove.

overrev

clean with alcohol then spray with wd40 then add a few drops of after run oil and you should be fine. mike

G35Coupe

Yea it'll flood..but come right out the exhaust or glow plug hole...thats the point!

This line of advise is amazing.
It amazes me how unwilling to do a little work to insure the engine is "Perfect" before you risk running it,
It would take about 20-30min to break it down, clean and re-assemble the motor. Then you would know for sure it is safe to run. Seams like time well spent to me

Good 'ol Sam never told us what enigne it is, maybe it's a worn out RTR enigne or maybe it's a brand new p5. Either way I'd want to know everything is copo before I ran the engine

sovietspyguy

if you flood the whole engine, then it wouldn't, and that would be necessary since it probably got into most of the engine. Backplate off is the best way.

Sypro

This guy is right listen to him. What would you rather do spend 5 mins flooding your motor with wd-40 and then later have it blow or sieze. Or spend 30 mins taking it apart and cleaning it and have it be fine. Up 2 you. This is one of the them things where the risk factor is to great to take the risk. If you cant make up you're mind call up you're lhs and they will help you.

i read in a magizine once to put after run oil in the carb, and i accidntly put in air filter oil but nothing happened

better safe than sorry, take it apart and clean it! 20 minutes and your done, with no worries. or flood it and take your chances. makes more sense to clean it right.

i only got one or two drops of traxxas fuel in it and I dont think it made it to the engine so I should be safe

I don't know why this is such a big deal?? All you need to do is take out the glow plug and flush it out with some fuel! [sm=idea.gif]

This thread is incredible? No harm will be done by using airfilter oil instead of afterrun oil.

However, WD40 is BAD FOR AN ENGINE and I can't believe how many people recommend WD40 for an engine.

Here is why WD40 is bad:

1. WD40 is an excellent rust remover. Spray a little WD40 on rusy piece of metal and you will notice that it causes the rusty oxidized metal to loosen up.

2. Almost all glow engines have some rust/oxidation inside of them. Rust/Oxidation occurs on backplates, pushrod surfaces, the crank counterweight (back of crank) and the bearing outer races.

3. If you WD40 your engine, you will loosen the surface oxidation that is inside your engine. This gritty oxidized material is the same stuff used to make sandpaper. This fine gritty particulates can scratch your piston wall easily.

Ergo: Don't use WD40.

Advice to poster: Flush your engine out with fuel if you are so concerned. Personally, all I'd do is just run the engine for a bit to flush out the airfilter oil and then add a little afterrun oil (ATF fluid is what is sold as afterrun oil) to your engine.

If WD-40 is bad for an engine than why does Sirio and Traxxas reccomend that you put in either after run oil or WD-40 in the motor after a days use? I trust them over you.

jessiej

WD-40 is unlikely to harm anything short term. There are many far better oils for storage beyond a week or so. Famed model engine guru the late George Aldrich recommended Rislone, but ATF, Marvel Mystery Oil and numerous others are fine. Hobby shop after run oil is fine too, but compare the price of a couple ounces with a quart of ATF etc.

Filter oil in the engine should be a non problem. Just wash it out with model fuel, Gumout carb cleaner ,MEK or any of a dozen or so other solvents and run the engine. Flood the engine? Pour the excess fuel out the exhaust or glow plug hole or simply let the thing sit awhile.

BTW, a conversation with a competent gunsmith will convince you that the only use for WD-40 should be as a aerosol solvent, not as a preservative or lubricant. I have, however used WD-40 in the gallon cans as a short term preservative or as a penetrating oil on farm equipment etc.
