Is a Manifold/exhaust system that is LEAKING exhaust gas a failure?


Recommended Posts

Im not an MOT tester just yet haha, nearly, done a lot of training just need to do the course :)

Ehh as far as im aware its an advisory if its not excessively loud. It might fail if its leaking so bad that it affects the emmisions. Other than that it should be ok, ie a small blow.

Exactly what mine failed on last week. Yet to check it to see if it has any leaks. Grrrr

99% sure you have a leak somewhere between turbo and back box

i learned the hard way my reading was off to so i thought my 02 sensor was fucked so went toyota to buy new 1 , went back to test centre and same result came out !! then the tester told me its almost always a leak in exhaust !!!
