Simple Steps to Troubleshoot Engine Oil Consumption Problems


Does your oil level drops with each oil change? If the engine is new you will not notice such a thing but if the engine is old you will not have the luxury because with time Japanese used car auction vehicle engines does not provide the same performance.

Also, if you tend to add some oil here and there, that is okay. But if you have to add oil in quart then there is a serious problem. The problem lies in your piston rings as they are worn out. Moreover, it can also mean that oil leakage due to cracked part or the leakage can be through head gasket into the cooling system.

Repairs can be expensive but there are some steps via which you can troubleshoot these matters. Matters could range from the following:

1.      No smoke in exhaust

The car is consuming a lot of oil yet there are no traces of smoke present in the exhaust. The oil level is also low during oil changes. However, you are beginning to notice it now, what to do? You can seek to fix it. The problem may be that PCV system is not functional. You can simply replace the PCV valve.

Other problem could be that engine is experiencing mechanical problems. You can address it by checking compression and you will have the true picture of engine’s condition. Also, engine gaskets and seals may be damaged. Replace them pronto.

2.      Coolant brown and foamy

Here the engine eats up a lot of oil. You will notice the coolant has turned brown and foamy. Your car is losing oil from somewhere, however, you are not able to notice any apparent leaks. There are a number of reasons for that.

You have blown head gasket. You can address it by replacing the head gasket. It could also be due to cracked cylinder head. You can try removing and then subsequently repairing the head. Otherwise replace the cylinder head with fresh component.

Other common reason could be that your car is leaking oil-to-water cooler. There are certain oil coolers which circulate the oil inside a chamber which is filled with coolant. This way there is an exchange of heat among the two systems and which is why a leak in the oil line on the inside will have caused the oil to drip on to your cooling system. The remedy lies in replacing or having the repairs of your oil cooler on prompt basis.

3.      Oil Puddles or Drips under Car

Again the engine is consuming more oil than it should. You can spot oil puddles underneath your car. There is oil leak but you don’t see smoke or smell the oil burning either when you make a stop. Here you need to maintain the proper oil level.

Here the issue is that PCV system is not working appropriately, the engine gaskets and seals are damaged or the oil filter is not tightened adequately. Respectively, you need to replace the PCV valve, find and locate gaskets for their replacement and either tighten or change the oil filter.

And you are good to go!
