MOT No. 27
The exhaust system is screwed at the exhaust manifold to the gearbox with a holder. Under the bottom of the car, it is fixed freely on rubber cushions.
Check the rubber cushions for wear, tears or other damage, replace the cushions if necessary.
Check exhaust manifold bolts for tightness (30 Nm) and on the gearbox bracket (25 Nm), but do not use excessive force.
With the engine running, close the outlet (And) exhaust system with a rag, holding it in his hands. After a short time, the engine should stop.
If you hear hissing sounds and the engine continues to run, then the exhaust system at the place where the sound comes from is leaking.
A lower exhaust system rumble than usual and loud pops when coasting indicate rusted exhaust pipes.
Mufflers start to rust at the welds (connections). If they have to hold on for some time, then they should not be destroyed by light tapping with a screwdriver in these places.
