How can you tell if a head gasket has blown?
This test will show if the compression has leaked into the cooling system, and therefore if the head gasket has blown. However, it won’t show if there are any other problems with the head gasket, so the absence of carbon dioxide in the cooling system does not guarantee a healthy head gasket.
When is a head gasket failure bad news?
A head gasket failure is bad news, very bad news, and will require immediate attention. A head gasket can fail in a number of different ways (coolant leak, oil leak, loss of compression), some of which we told you about recently, and all of which are bad news for the engine.
What causes blue smoke from a faulty head gasket?
A faulty head gasket can result in blue smoke coming from the exhaust caused by oil leaking past the gasket and into the cylinders, where it is then burnt as part of the combustion process.
Can a faulty head gasket cause an oil leak?
A faulty head gasket can also allow engine oil to leak into the coolant passages in the cylinder head. This often shows up as an oily/milky residue in the coolant expansion tank, as the oil floats to the surface of the coolant. Again, be careful though, as this can also be caused by a leaking engine oil cooler or transmission oil cooler. 4 Smoking
Are there any problems with the EVO engine?
The Evo’s don’t have heat problems, don’t have chains or belts in the timing chest that can do really bad things internally, don’t have problems with the crank, or the main bearings, don’t have problems with the comp sprocket, etc, etc. Can you tell which one I prefer? Re-reading your post I see that your scoot has only done 32k miles.
Where can I get parts for my EVO engine?
For now go to Bandit.com and follow their directions to register your EVO for their parts book. This will get you into looking at copies of Harley parts books for your year. Go to engine and oil pump and you will find the tappet screen and where it is. It will also show you how it goes back together.
What to watch out for on a Harley Davidson Evo?
If the base gaskets start leaking (one or both), fix that right away or you will have a blown head gasket once the jugs start moving. As the fine gents said. I can only add that the EVO bottom end is mostly bullet proof, in particular late EVO’s.
When to change base gaskets on Harley Davidson?
Runs great but as she gets older, want to be pro-active instead of re-active. Make sure you warm it up until the valve covers are warm to the touch before taking off on it. That will extend the time until you need to change the base gaskets.
