Question about 1986 Honda Civic

3 Answers

Oil in the Radiator, and engine is running a little hot. I am wondering if it is an easy repair, such as a head gasket issue (which my uncle can repair very easily,) or if something is wrong with the head itself. Thanks!

Before assuming its the head or head gasket,remember that your vehicle has a line that carries oil to the radiator to be cooled,and a line that carries it back to the engine. these are called oil cooling and return lines. if the radiator wall has an internal crack in it,it will cause oil to leak in the radiator. so have that radiator checked b4 spending money on a head or head gasket. a heck of alot cheaper.

My uncle put car was running hot my uncle,PUT WATER IN WHERE THE OIL GOES,AND OIL SHOUT EVERWHERE,SO I GOT IT PULLED ,ITS BEEN DRAINED,OIL CHANGED,SO WHY IS IT STILL RUNNING HOT?


From my experience, oil and water mixed together produces a muddy, inconsistent, frothy slime. So you need an additive the will open your oil passages back up, and help your oil pump build correct pressure. A product called "Seafoam" is ideal for this. Add 1 can of Seafoam oil and gas treatment to your oil (don't overfill). When your temperature stabilizes, change your oil again and add 1/2 can of seafoam this time. You should be OK.

Now, before get to work on your car, consider any other possibilities that may have occurred. Perhaps the car had blown a head gasket and now water from the cooling system is crossing into the oil return port in the head. This would make the oil on the dipstick appear exactly as if someone put coolant or water in the oil fill port.

Another possibility is a cracked head. Not the end of the car's useful life but definitely a few days in the shop. Same oil appearance as mistaking oil cap for coolant cap and blown head gasket.

OK, so lets diagnose: Let the car cool down completely. Remove the radiator cap. Start the car and carefully observe the water in the in radiator or coolant reservoir.. I say carefully because the coolant can suddenly Kick up in your face, especially if the separations between oil, water, combustion chambers has been been breached. If you see bubbles or a splashing of water out of the radiator, then you'll have to deal with servicing the engine heads. Hope this helps, remember to keep the kids back from the car, wear safety goggles and gloves, don't get in a hurry, keep a log of what you do and in what order, and make sure the engine is cool. It should take no more than 30 seconds to make this initial diagnosis.

Van blowing cold air


It has air in the line. let ir idle with the radiator cap off for a little while and the air will work its way out. You may have bigger issues, but I do not think you need to clean heater core because you get heat sometimes. Do you see a lot of bubbles when you take the radiator cap off when running, head gasket if so.. You can take the cap loose while the engine is running, but not after you stop it, it will be to hot. Good luck

Going through alot of oil and antifreeze.... have oil where my spark plug is


The engine can burn alot of coolant before you see any smoke.
And having a cooling leak in the engine could cause it to run hot at times.
If you are adding coolant every week and don't see any leaks, the engine has to be burning it. Most of the time it is a blown head gasket and cracked head or block.

'98 dodge neon 2.0 dohc runs hot,new head gasket,radiator cap,no leaks or water in oil,new temp sensor,could bad intake gasket cause this?


Hi, Check the right amount of water it's holding if it is not as much as should be then what will clean all out is water mixed with caustic soda. Take great care use gloves ensure you don't go onto anything except inside your radiator & engine heater etc ONLY! run the engine so water gets hot when its run hot for ten minutes approx, drain this out REMEMBER THIS IS ACID. So take GREAT CARE. Clean your drains at home out for instance, This should have cleaned any blockage rust etc. After draining let cool a little 10 minuets then start engine & start to refill with antifreeze/water mixture by running the engine with your heater turned on to hot as well this should ensure no air locks & now the problem should be solved. Please leave me feed back Malcolm Campbell crossflowspeed@hotmail.co.uk Thanks.

I have a 2006 chevy aveo and it runs hot when I run the air conditioner and the radiator tank is empty, when I put water in it, it makes a crackling noise and then when I try to give it gas to make it go...


Does the empty radiator have anything to do with the AC? OR is it always empty? You should fill the radiator and the tank when the engine is cool. Never take the radiator cap off a HOT engine. It can shoot hot steam and water all over you and cause serious burns. With the engine cool, take the radiator cap off and fill it with the proper coolant, not just water. The coolant instruction label should be on or near the radiator. Fill the radiator completely, You may have to finish it slowly because of air trapped in the system. You can run the engine a short time to assist in filling the radiator. When the engine is running, if a lot of air bubbles out it could have a blown head gasket. DO NOT ALLOW THE ENGINE RUN UNTIL IT GETS HOT. If there is air in the system the coolant will go down and you can continue to fill it. When it is completely full, shut off the engine, top off the radiator if necessary and put the cap on completely and tightly. Fill the coolant tank to the full mark with the same coolant as the radiator. Drive the car and see if it overheats. If it smokes and has water coming out the exhaust, it probably has a blown head gasket. After it cools, check the radiator again. If it is low or out of coolant, again - blown head gasket. A blown gasket can **** coolant into the combustion cylinder OR can blow exhaust back into the cooling system. It can also allow motor oil into the radiator. Look for oil when you are filling the radiator. Also check the engine oil, if it has coolant in it, it will be a thick gooey mixture. In either case you should have the car towed to a qualified mechanic for testing and repair. If none of these things are occurring, look for a leak in the coolant system. A bad hose, or a leaking water pump. A defective radiator cap or the cap is not on tight. Look for the easy things first. Good luck.

Heating has stoped working and there is a little water in the oil, think radiator may be leaking, does my car just need a new rad


water in the oil will turn the oil brown like mud,is that what you see? if so,then you have a blown head gasket,do not run motor if this is the case as the motor wiil spin a crank bearing or lock up.are you sure about the water in the oil? look for real brown oil just like mud with bubbles on the oil dipstick. if the heats stopped working it may be because the radiator's low on fluid. look in the radiator for low coolant,if you can't see the coolant when you remove the radiator cap,it's low. with engine cool,remove the radiator cap 1st then start the engine. do you see steam and fluid blowing up frome the radiator? if so,you have a blown head gasket in the motor. head gaskets can blow and leak water into the oil or oil into the radiator. or blow and leak into the exhaust sysytem and blow coolant out of the tail pipe. three different ways for a head gasket to blow. usually the head gasket only blows when the engine has been run really hot!!! hope this helps.thank you for choosing fixya .com

Engine oil leaking into radiator


you either have a cracked block or the head job they did is not good. It is very easy to screw up a head job. Also they may not have put in the right gasket. If they had to shave a lot of the head off, then you need a thicker gasket. If they used the standard head gasket will break or leak again.
