Unbolt the burner and slide it out of the way.
Depending on the set up.... well simply unscrew all the bolts surrounding the burner itself(obviously depending on set up) you do not need to take the burner out if you are careful. remove this plate in my case it is cast iron and secured by five bolts. After removing it you will notice what looks very much like foam. this is incredibly fragile if you notice parts that are uncovered by this material or cracks you need to replace the lining. The combustion chamber is the lower chamber where the burner is inserted. If this helps...well great.

Either a combustion chamber, an oil vein, or both. Check for white smoke out the tail pipe for a combustion chamber leak and if the oil on the dipstick looks like chocolate milk it's contaminated with coolant.
Put on FOD free apron, carry power full torch, magnifying glass to check minor nicks.
a engine will ping when the gasoline fires premature in the combustion chamber due to poor quality gas or excessive loads, (towing, hauling loads) or engine overheating causing excessive combustion tempatures. also check the EGR (exhaust gas recirculation) system for proper function, it is designed to lower combustion chamber temps and may be the cause.
White smoke is usually a sign of water in combustion chamber-check oil for any signs of water in oil
The muffler is most likely clogged and will not allow the exhaust gases to exit the combustion chamber. Check the muffler for obstructions or replace the muffler.
When the furnace in your home goes out, there are a few things that you need to look at before you get a new furnace. Get the furnace serviced by a professional electrician who will check the heating coils as well as the filter in the furnace. Check the circuit breakers in the furnace to ensure that they are working properly. If the breaker is not making contact, this could be all that you need to replace.
Blue smoke in both petrol and diesel engines is caused by the burning of engine oil during the combustion phase, i.e there is oil in the combustion chamber. The oil could be entering the combustion chamber via the valve stem seals or the oil rings. Also check that the oil level is correct as too much oil can cause blue smoke Also check that there are no oil leaks that are allowing oil to enter the exhaust system. If all that is in working order, I suggest you pull out the engine and get it overhauled.Read more: What_causes_black_smoke_or_blue_smoke_in_gas_engines
There is no fuel getting to the combustion chamber. Things to check: clogged fuel filter; crimped fuel line; carburetor settings; obstruction in fuel tank.
thick white smoke generally indicates coolant leaking into combustion chamber . check for faulty head gasket od cracked head
The most important thing to check when buying a used oil furnace is does it still work. Check to see the condition it is in, check all wires, tubes, etc. The best bet would have a furnace man check it as he would know what to look for.
