How to Remove Heat Stains on Engine?

No. It is not a solvent. It does not contain MEK, Xylene, Methyl Chloride, Methylene Chloride or any similar volatile organic compound and therefore is not an inhalant concern.

It is considered a Hazardous Chemical due to the strength of the sodium hydroxide and is labelled as such so, don't get it on skin or clothing that contacts skin. Don't get it in your eyes. Handle it like you would caustic oven cleaner or drain opener; gloves and eye protection.

so are you saying Ms Super Clean, is - 'cheap'? I wouldn't tell her to her face.

Yup and smells better too.

Soak your brake rotors in it to remove brake pad deposits. Remove them first.

I don't think any detergent is going to work. Aircraft stripper may work (this is to repaint/refinish cylinder head covers). A wire brush may pit magnesium/magnesium alloy. I''m not too experienced working with magnesium, so I don't know how soft it is and what you can get away with.

Paint with high-temp primer and paint.

^ ^ this ^ ^

If the heat melted the sight glass & toasted the paint on the head covers..I would definitly be concerned about the condition of the internal plastic parts...cam chain guides, timing chain guides, oil inlet assy...

It sounds like I'm definitely going to have to go deeper than simply removing the valve covers to check those things. Or is that as far as I'll probably need to go?

You'll see the cam chain tensioner and guide rails when the valve covers come off. The ends are unsupported, if they're fine, chances are very good the rest of their length is. The timing chain tensioner and guide are in the front of the motor, which you'll want to partially disassemble to inspect the HES wiring anyway. I'd also look at the belt, it may have seen damaged as well.

It looks as though you are correct, I could not find ammonia in its ingediendts. But it sure has that high ammonia smell and pain in my lungs if I breath it in.

It is labeled as a level 3 health hazard and a high inhalation risk...ammonia or not. It is also listed as Citrus scented as it shows on page 3/7 of the MSDS sheet...it is listed as a hazardous material as per OSHA regs and is a HAZMAT chemical

Sorry for mis-speaking. My intent was to warn the user to be careful. I may be thinking of my Super Purple cleaner I have that is citrus and ammonia....one of them. But they all tear up my lungs if I get a whiff.

Yep.

We work with different solutions of sodium hydroxide - and it is plumb ass dangerous.

We had a pump that blew a gasket and sprayed a women who was standing near by - they rushed her to a safety shower probably within 45 seconds and during that time she lost 80% of her hair on the top of her head. Not nice stuff.

That slimy feeling when you rub your fingers together with caustic on it - is your skin melting off. It's not like an acid, with caustic you have to continue to rinse with water for 15 min.

Anyway...

Its the loss of temper to the input splines that you may want to look after. In spite of all the postulations on sudden input spline failure it is actually caused by the owner over-heating on the side stand. Splash lubrication of oil originating in the clutch slave cavity can't make it to the splines while on the side stand.

Seriously? You think a motor hitting maybe 250-275° will remove the temper from the input splines?

You would have to melt the case to do that!

Super Clean is not a detergent.

Aircraft paint strippers are hazardous and require a respirator as do the aircraft paints. Unless you are experienced and have the equipment, stay away from them.

If you want to restore the factory look and durability, have the OHV covers powder coated.

Yes, if the splines were made of silly-putty.
