Why does this Nissan altima only run on two cylinders when it has spark to all four and gas to all four?
You may have a blown head gasket. If you have a compression tester available, check compression on all four cylinders andcompare the readings. If adjacent cylinders read lower compression than the other two, it is likely the head gasket is blown.
Can a bad intake gasket cause water to mix with oil?
Yes, a bad intake gasket can cause coolant to mix with engine oil. Indeed a bad lower intake can cause this. Who ever said the head gasket is a moron. You can't assume this all the time. This is why you have diagnostic tools such a a compression tester and a leak down tester. For example, my compression is good, and the valves are not leaking past the specs. However, there is air coming from the lower intake. The gasket is bad. Also, it's always suggested that you change the oil after the gasket just to be sure no water got in the oil pan from doing the gasket.
What are Chevy big block head gasket differences?
There are two basic head gasket materials used. First is the steel shim type, with is thinner, and will up your effective, or mechanical compression ratio. The second is a composite type, that will lower compression, as it is thicker, bjut, seals better.
Would a blown lower intake gasket create milky oil?
yes it can water can leak into the intake valley and get into your oil resulting in milky oil
How can you convert a vehicle running on premium fuel to run on unleaded fuel?
Replace the head gasket with a thicker one, this would lower the compression ratio.
Replaced lower intake gasket oil still in radiator What else could it be Could I have a cracked head?
blown head gasket is the usual reason for oil in coolant or radiator. sad part is if you have already replaced intake gasket, u wasted your money as you will have to replace again when you fix head gasket
How do you know if you need a new head gasket in Buick regal?
The best test is to perform a compression check on each cylinder. A low reading on any one will indicate a leak. If the gasket is blown between two cylinders, both cylinders will have lower readings than the others. You can also check if there is water in the oil pan by checking the dip stick. This is only helpful if the leak is to the water jacket. Knowing why you suspect a head gasket problem would be helpful in determining the cause.
Coolant leaking into lower manifold Taurus?
A blown head gasket can allow coolant to see into the manifold, and out the exhaust. A broken piston ring can also cause this problem.
Does the heater have anything to do with a blown head gasket on a 1998 Oldsmobile Silhouette?
The heater generates heat by blowing air over a small radiator type device (heater core) under your dashboard. The device runs hot coolant through it continuously. If you have a blown head gasket, your coolant is being evaporated trough the firing chambers and tailpipe. When the coolant level is low due to evaporation, there is no water to flow through the heater core. Keep in mind if you are not certain that this is a blown head gasket, these models were notorious for a defective lower manifold gasket leak that caused it to lose coolant the same way a head gasket would.
How do you replace the lower intake manifold gasket in a 99 Chevy Venture?
there is no lower intake gasket, only a front and rear gasket
Your 1998 Isuzu rodeo started blowing big plumes of white smoke out the exhaust and also leaking coolant around the lower part of the manifold whats wrong?
Sounds like a blown head gasket. Have a mechanic do a compression test, and check for oil in the coolant and/or coolant in the oil, (white foamy material around top of fluid level.)
Can you fix a blown intake gasket with chemical additives?
no you need to replace the lower intake gaskets . P.S. should have the rear head checked for leaks also they are known to leak also
