When to look for an airleak when your engine you?
Piston seizures related to air leaks are not just a result of an engine being run with an air-leak, but rather a result of the engine being run at close to maximum output with an air- leak. Where to Look for an Airleak When your engine seizes a piston…do not disassemble it.
Can a 125 horsepower engine have an air leak?
Since the 125 is constantly being operated at close to maximum output and peak rpms, the tolerance for an air-leak of any kind is “zero”. A high-revving 2-stroke engine with a significant air leak, is an engine that will soon produce a seized piston.
Can a newly rebuilt engine have an air leak?
Even engines that are rebuilt by the best technicians can air leak. About 20% of all freshly rebuilt engines will have small hidden air leaks. That’s why most professional engine builders pressure test every engine before and after rebuilding. Installing fresh seals and gaskets is by no means a guarantee against air leaks.
Can a crank seal leak on an engine go unnoticed?
Since most ignition covers are airtight themselves, an ignition-side crank seal leak can go on unnoticed for a long time on a stock output engine. If you find an oil residue in the ignition compartment when removing your ignition cover, there’s a very good chance that your front seal is bad.
