look for any mixing of coolant/water with your engine oil...on dipstick (looks like chocolate milk or frothy white), check your coolant reservoir for oil contamination...these are typical signs of a blown head gasket
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.
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.
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.
Check your cylinder pressure with a compression gauge. The gauge will hook up to your spark plug openings.
antifreeze in the oil should be a milkshake color
Pressure test the cylinders, but smart money will replace both.
A compression test will verify if the head gasket if blown or not, the majority of the time.
see if your oil looks like chocolate or just has water in it
Any smoke ( blue ) coming out the exhaust ?
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
Coolant mixing with the engine oil and/or engine oil mixing with the coolant could be symptoms of a cracked head or blown head gasket. A whitish sweet smelling steam coming out the exhaust is another symptom.
