What else can I help you with?
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 should compression on 1995 polaris Indy 500?
The compression on a 1995 Polaris Indy 500 snowmobile typically ranges between 120 to 130 psi. It's essential to ensure that the compression is within this range for optimal engine performance and reliability. If the compression is significantly lower, it could indicate issues such as worn rings, a blown head gasket, or valve problems. Regular maintenance and checks can help maintain proper compression levels.
What is the compression on a 1978 Johnson 85hp?
The compression ratio for a 1978 Johnson 85hp outboard motor is typically around 130 to 150 psi per cylinder when measured with a compression gauge. It's important to ensure that all cylinders have similar readings for optimal performance. If compression is significantly lower in any cylinder, it could indicate issues such as worn rings or a blown head gasket. Regular maintenance can help maintain good compression levels.
What is the compression on the cylinder on a 1995 Mercury 60hp?
The compression on a 1995 Mercury 60hp outboard motor typically ranges from 90 to 120 psi across all cylinders. It's essential for each cylinder to have similar readings for optimal performance. If compression is significantly lower in one cylinder, it may indicate issues such as worn rings, a blown head gasket, or valve problems. Regular compression checks can help maintain engine health.
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.
What should the compression on a 1980 evinrude 150 be?
The compression on a 1980 Evinrude 150 should typically be in the range of 90 to 120 psi for each cylinder. It's important that the readings are relatively consistent across all cylinders, with no more than 10% variation between them. If the compression is significantly lower, it may indicate issues such as worn rings or a blown head gasket. Regular maintenance and checks can help ensure optimal performance.
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.
What is normal compression for a 25 hp 2 stroke Mercury?
Normal compression for a 25 hp 2-stroke Mercury outboard engine typically ranges between 90 to 130 psi per cylinder, depending on the specific model and its condition. It's important to ensure that both cylinders have similar compression readings for optimal performance. If compression is significantly lower in one cylinder compared to the other, it may indicate issues such as worn rings or a blown head gasket. Regular maintenance and checks can help maintain proper compression levels.
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.
