I put a new head gasket kit on my car because it was overheating. I found oil in the water. That is what lead me to believe the head gasket was blown and I believed replacing it would fix the problem. After doing all that work and replacing the thermostat and radiator cap it is still overheating and now it is running rough. I believe the timing is off a little bit. Before I started this job I could hear and feel the thermostat and radiator cap opening and closing real fast when the engine started to overheat. That is why I replaced them. But this continues to happen as well as the overheating. Where do I go from here?

When a head gasket is replaced most mechanics check for flatness on cylinder head due to being aluminum on a cast iron block make sure head gasket was installed correctly and not up side down. You might check for cracks as well. If cylinder head bolts look like one with arrow in picture they should have been replaced and with your mileage it was a good idea to change them anyhow. Also oil can come from transmission not only engine. It looks like you will need to redo your work if running rough but scan for codes first as it may be something else.

Hi Byon,

Here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com
