I rebuilt my 2000 1.6 Lanos head with new valves/water pump/timming belt over 2 years ago. 5 months after the rebuilt , I developed a small water leak.
last week I removed the cylinder head and found the head gasket blew at cylinder 3. After examining the graphite gasket I noticed the gasket material wore out near cylinder 3. Water was leaking into cylinder 3, the gasket wore out due too water corrosion (graphite material rusted out). between the water gallery and cylinder chamber.
For over one and half years I just added water! I didn't use coolant, because I was too lazy too fix my small water leak! Now I'm paying for it!
FYI: Coolant acts as a lube for your water pump and prevents corrosion/rust. This means it prevents your graphite head gasket from wearing out too! I also got a P0420 code.
So, I just ordered a new head gasket. It's a little different from the last one I bought 2 years ago. The first gasket I bought had a blue sealant, that went around the edge of the black gasket surface. The new head gasket I bought, does not have it.
You guys think I should add gasket sealant around my new gasket?

PS: I called the ebay store I bought it from, the guy who answered didn't know. Some guy in the back ground yelled "tell'em to just throw it on!". That was their answer.

Yeah, I bought a replacement water pump and timmimg belt.
I don't think anything else is damaged, when I pulled the dipstick it looked normal. T
The dipstick didn't have that moca color, which would indicate water mixed with oil. I even drove it 1//4 mile after adding more water. And still no water on the dipstick. I did find water mixed with oil under the valve cover, but all valve lashes and cam surfaces look fine.

unless the gasket has the sealant built into it, you have to use some.
Even if it does have it built in, i would recommend using extra as their wouldnt be enough built in to feel safe about it
Don't forget to use new head bolts as well, just in case your existing ones have stretched and torque everything to specs
good luck!
