If the gauge fluctuates, one or more cylinders are leaking vacuum through a reciprocating part like a leaking intake or exhaust valve or burned piston. Consequence Of Diesel Engines High exhaust temperature. There are lots of consequences which high exhaust gas temperature can cause to the engine parts, these are: – exhaust valve life time reduces up to 50% if continue with same high temperature. – Cylinder liners wear more faster as required.Even when the surface temperatures of manifolds and headers are the same, the headers have maybe 3-4 times more surface. They can radiate 3-4 times more heat. What does a bad exhaust manifold sound like? A faulty exhaust manifold gasket will produce an exhaust leak that will sound like a hissing or tapping sound coming from the engine. sooner softball Watch out a lot . Also question is, what causes popping on deceleration? Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel. Also Know, why does my dirt bike backfire on deceleration?31,800 Posts. #6 · Aug 20, 2017. No , its not normal , If your running the stock air box with snorkel then yes it will go up slightly sitting but should stay with in about 10-15 deg of ambient temp.
