Head gasket issue
It appears that I have a small head gasket issue? Did compression check on my engine today and noticed anti-freeze blowing out of the number two cyclinder when the engine was cold. Now when I did it again with the engine at operating temp there was nothing coming out.
How hard is it to change the head gasket?

If you are asking the question you might want to get a little help from a knowledgable buddy. It's worth doing yourself but have someone with you that knows whats going on.

Thanks for the replies,
Yes I have the tools and actually rebuild this engine about ten years ago. I test all the cylinders for pressure and the bottom end appears to be good. And yes I will have both the heads checked for cracks but, I don't want to have them reworked because it may cause issues with the bottom end.
I was really wondering if, there's anything out there that may seal the small leaking crack instaed of having to tear the whole top end apart?

Honestly, Ive tried that stuff a few times as a patch. Some techs say it works, but for me it didnt. If you do use it, theres several steps that have to be done for it to work. Its all listed on the bottle. In other words, you dont add to coolant and drive off.
One thing that comes to mind if you pull the heads. There are a couple of alignment collars that seat in the block. These help the head gasket stay in place and align the head as you lay it back on the block. Sometimes these collars pull out of the block and stay with the head. Get some pliers and pull them back out, and tap them back into the block. Match up your head gaskets for left and right, and that the gasket has proper steam holes as your old one.
