The majority if not all the "engine rebuild in a can" stuff is junk. You can't repair worn out parts with an additive. You can't revitalize dried out and cracked valve seals. The stuff isn't designed as a one time use item. You're supposed to use it regularly and considering the average cost, you can quickly add up to the cost of a rebuild and your engine still isn't rebuilt.

 

as you said its a band-aid , a poor one at best . if you are looking for cureall from a bottle , FOGEDABOUTIT .

 

If you could open a can and pour something into a worn-out motor and renew it that cheeep and eeezy, there'd be a far sight fewer machine shops and engine rebuilders in the world today.

No, it doesn't "work" like that. Yes, alot of those DO contain additives and whatnot that will help a little bit. Alot of them also contain oil thickeners that make the oil not flow as freely, and will therefore ACCLERATE wear; but temporarily, it may seem to you as you stand next to the motor pouring, that the motor makes a bit less noise because they cushion parts that are banging against each other from the slack between them. They CANNOT and WILL NOT undo damage and wear that has resulted in missing metal. Notice when you open the can, there's no steel or cast iron in it; therefore, pouring the contents of the can in, will not put steel and cast iron (and copper and aluminum and all the other metals present in the engine) back, and make the parts like they were before they got worn or damaged.

 

On the same subject, anything claiming to have Teflon in it to reduce friction is a waste of money. Teflon doesn't belong inside an engine and any that's mixed in the oil will get trapped in the filter.
