prelude white smoke and seems to be getting hot under hood but temp gauge is fine?
i just got a 93 prelude vtec it was sitting for about two years barely driven i changed the oil and drove it for a little bit. It seems like it running hot cause the hood is really hot and it smells like old burned gas or exhaust is coming out. It runs fine i just didnt know if it could be an piston ring problem becuase it blue smokes sometimes and the smell is just not normal. Could it be from just sitting a while or what need tips
Chosen Answer:
there are several things that can be causing it but most likely it has to do with the car sitting.
the first thing to do is to check the oil level. If you over-filled it when it was changed it could cause the excess to be forced up into the combustion chamber and burnt.
the second is that that the spark plugs may be fouled so that you are getting an incomplete burn in the combustion chamber.
the third is that the car may have been flooded trying to start it and that would dilute the oil and cause it to burn through the PCV system.
the fourth could be an external leak from a dry valve cover gasket causing the burning smell.
The fifth would be condensation inside the exhaust system that has accumulated inside the muffler, pipes or catalytic converter while the car sat. Its not unusual to see white smoke from the exhaust simply because of water that has condensed inside the exhaust system while the car sat.
if it were a head gasket the smoke would be pure white when the engine is hot.
i’d suggest running the car for a few days to see if it clears out. If not, then start with the other maintenance items (spark plugs, valve cover gasket, valve adjustment) and if the blue smoke is still evident, then check the compression.
if the car was running okay before it sat then chances are your problems are related to storage and not something that went bad mechanically.
It may be the head gasket. The smoke and the unusual smell are symptoms of a blown head gasket.
