Check your oil dip stick. If the oil is above the full level and discoloration, it indicates that the oil and water has mixed due to worn out gasket, same thing applies with the block and all of this scenario always start with sudden rise of temperature or engine overheating.
A compression test will tell you if a head gasket is blown on ANY engine. Also, white smoke tells you that your burning anti-freeze, which means a head gasket is blown.
If you suspect the head and/or the block, have them "magnafuxed" by a machine shop. On the other hand, as you're pulling it apart, check the head gasket and if it's shot, there is usually only the one problem.
Just look at your engine oil and you can tell, if it looks milky there is water getting into the oil and that's the sign of a blown intake gasket or head gasket.
A dye test will tell you if your head is damaged in the event of a blown head gasket. It turns colors anywhere it is leaking on the head, hence where any cracks would be.
A compression test will verify if the head gasket if blown or not, the majority of the time.
A blown head gasket can have many symptoms including loss of coolant out the tailpipe, mixing of coolant and oil (which makes the oil look something like a chocolate milkshake), loss of power, or low compression in one or more cylinders. A cracked block can also exhibit these same symptoms but is less likely.
I hate to tell you this but I just paid $3,500 at the Nissan dealer for head gasket replacment.
antifreeze in the oil should be a milkshake color
Pressure test the cylinders, but smart money will replace both.
yes but if it is a blown head gasket it will make it miss and put steam and some water out the tell pipe if its not doing these things then check your anti knock sensor
Any smoke ( blue ) coming out the exhaust ?
Either a leaking intake manifold or a blown head gasket. You can take it to a repair shop and have a block test done. That will tell you if it is a head gasket. DO NOT drive anymore than needed as the water will destroy the engine bearings.
