Big job, sorry!
If the head gasket has failed, you would have to replace it. Or better still, get another engine from salvage yard.

Head gasket or IM gasket? 05 rendezvous overheats..pushing fluid back to top of radiator or to reserve when cap is on. i think there's antifreeze on spark plug threads and maybe in cylinder for #2..ge


If it has the 3400 v6, better known as the 3.4litre, this motor was prone to head gasket failures. Antifreeze on spark plugs is a sign of head gasket failure, so is antifreeze in the oil. Have a mechanic put a dye in the cooling system that is detected with a certain light and that will tell you exactly where it's coming from. Headgasket repair is not cheap. May be easier and cheaper to replace the motor. Wish you the best!

Removed #1 spark plug, Socket and plug covered in oil. Car was running rough, no power on acceleration.


Replace you valve cover gasket and tube seals. When installing valve cover back onto the head make sure the seals go around the tubes and don't get pinched.

Ok, so I'm not an auto machanic, I've got a 1995 Honda Accord with a 2.2l 16 valve engine, the problem: went to change out the spark plugs, the rubber boots were covered on the outside with oil. I...


I'm no mechanic either, but... the oil is not coming from the plugs. Probably running down from the valve cover gasket. You were right not to remove plugs with that gunk in there.You could try to soak the oil out with a bit of old towel. Is there any oil on the head under the valve cover? Have you been adding a lot of oil? Of course just a little oil goes a long way when leaking. New valve cover gasket should fix it.

The symptoms you describe is most likely caused by a blown head gasket. The only time the oil will become milky white is when coolant enters the crankcase. It is possible for a head gasket to fail and not contaminate the oil. There are various ways to determine which bank has failed. The method I prefer is to remove all of the spark plugs but keep them in order, so you know which spark plug belongs to which cylinder. Examine them, spark plugs from a properly running engine should look almost identical. Take a look at this link, NGK how to read spark plugs faq, your spark plugs should look like the one in the first picture. The spark plug from the cylinder that is burn coolant will not look like any pictured in the link. It will look cleaner than the normal spark plug because the coolant will cause a steam cleaning effect on the spark plug. Another method is to remove all of the spark plugs and crank the engine. Look for signs of water or vapor being expelled from the spark plug bore. An extension of this method is to stuff a wad of paper towel into the spark plug bore just enough to cover the bore. Hold it in place with a screwdriver or wooden dowel and crank the engine. Than examine the paper towel for the presence of moisture. Both of these methods work better when the leak is pronounced, not so much if the leak is in its early stage or small. I do not use this method because I find it unreliable and inconsistent but it does work for many individuals. The other option is to replace the head gasket for both banks, but that would increase the cost of the job.

You don't have to take the head off to verify a coolant leak into the combustion chamber. A coolant pressure test will tell, or even a leak down test.
But...if the head needs to be removed, it is a costly job, and if you have been driving it this way for a long time, it will do permanent damage.

95 camry won`t start


Have the head gasket torqued to 60psi each bolt? if so, either the spark plug grooves got a crack, or the head is bent due to a past overheat... or overheats. If so, send the head to a machine shop and have it leveled out, and replace all gaskets replaced when putting back on. That includes, manifold, header, and head gaskets, as well as the oil seals and O-rings. Hope this will help you.
