Hello guys, My car spits out alot of condensation and smoke from the exhaust when i rev it and i fear that it might be some blown headgaskets? Is there a way to see if its the head gaskets? I dont drive the car, just occasionally start it up. Do you think it'll just go away on its own if i start to run it more ? Thanks in advance.

 

water is a byproduct of efficient combustion....with that said how does the oil look? what about the radiator fluid? if you take off the radiator cap (do it cool)start the car does it gush water out?

 

Just starting it up really isn't sufficient. The byproducts rmodel speaks of don't burn off completely unless you drive the car. If it still smokes after it's been driven awhile then there's a problem.

 

i'll need to check if it gushes out...My car did overheat once on me but i thought it was the radiator that was clogged up which it was clogged so i had it rebuilt. The oil is brand new but when i drained the old one it was a bit creamy looking but i showed it to mechanic friend he said its nothing to bad?

I havent driven it since my gauges went bad. Would this byproduct burn off just letting it idle for a period of time?

 

Condensation will build in the oil unless oil pools a a fairly high temp.

My 67 oil pools at 165-180F after 32F interstate driving.

My oil stays very clear so I think 165F may be enough; 212F oil pooling would be a no brainer but not likely to occur w/ most engines.

I would not run engine to often w/o getting oil hot.

 

who needs gauges :P? drive it around the neighborhood to warm it up.

 

Letting sit and idle is probably one of the worst things you could do to your engine.

 

..i just dont what to have to tow it back home if it overheats or fuel runs out.

 

The engine isn’t working at its peak operating temperature when it’s idling, the fuel doesn’t undergo complete combustion. This leaves fuel residues that can contaminate engine oil and damage engine parts. For example, fuel residues tend to deposit on spark plugs and valves. As the amount of engine idling increases, the plugs’ average temperature drops, and they get dirty more quickly. My neighbor carbon up his valve seats so badly he had to pull the heads. All he would do with his 66 Fastback is back it out of the garage and let it idle for an hour in the driveway. With oil not reaching proper operating temps you'll also build up sludge. Excessive idling can also let water condense in the vehicle’s exhaust. This can lead to corrosion and reduce the life of the exhaust system.

There are also schools of thought that say long idling with accompanying low oil pressure can cause lubrication problems in the valve train area of the engine. Cam bearings and roller tappets rely on splash lubrication up there. 600 rpm idling may not allow enough splash to get those parts lubed enough.

If you're not going to drive it you're much better off stabilizing the gas and fogging the motor. Then change the oil, back off the rockers to take the pressure of the springs and let it sit.

 

Let it warm up then slowly rev it up and down like your driving it if it smokes then you got a problem.
