So today I've learned I do not have the tools to cut this aluminum. Tried cutting wheels on my rotary tool, and three wheels into it I hadn't even cut a half of one gasket. Time to try shears. These worked! Was able to start snipping away, then used a drill bit to get into the corners better, then I started snipping past my stop point rendering all my work useless. I gave up.
Kinda lost on what to do now. I can't purchase gaskets, and I can't make gaskets... the only thing I need to complete this and ride this thing. Ugh. What a kick in the crotch.

Is it a std Honda base gasket? What thickness spacer do you need?

So yesterday I gave in and made do with what I had. Started out by tracing a paper gasket to my cylinder. Cut the center out to slide over the cylinder skirt then with my fingers outlined the transfers and bolt holes. After cutting the paper gasket and verified it fit almost perfect I then traced that onto the aluminum sheet using a small screwdriver to scribe the aluminum. (Bad picture sorry)  Then I drilled small holes around the perimeter, leaving room to work with.  I then used small cutoff wheels with my rotary tool to cut the space between the holes.   I then used a die grinding bit in the rotary tool to clean up and shape the edges, finishing with a small hand file.   It matches up pretty dang good! I am adding a paper gasket to each side of the aluminum spacer then I'll double check my squish.  |

This thing won't stop blowing coolant out of the overflow. Looks like the head gasket isn't sealing correctly. I've redone everything multiple times now, sanding the top of the cylinder and head to what I'd assume is flat, fresh gaskets, torqued down with fresh bolts and I can't get more than 10 minutes before I'm getting a warm shower.
Dangit!!

Dangit!! As I mentioned before,IMO your plumbing is not correct. 90GTVerts is not routed like that and neither is mine or the others I have looked at. Hot water from the cylinder may be expanding the pump causing it to quit? Water may stop flowing or not flow well and boil in the head once it gets hot enough. I noticed in a previous post you had temps much higher at the head than what you were seeing at the radiator, could that be an indication of low water flow? Yes the head temp at the spark plug will be higher than the radiator temp but by how much? It may be that you are having sealing issues but it looks to me like you have that covered pretty well Cool water from the bottom of the radiator should be routed into the base of the cylinder then to the head. Hottest water exits the head and enters the top of the radiator. |

I swapped the routing around to push the hot water from the head to the top of the radiator, then the bottom of the radiator to the bottom of the cylinder... to flow up to the head and then to the top of the radiator again and so on. Still no good. I just need to verify this head is sealing. Seems like the engine warms up, breaks head seal and then pumps compression into the coolant system.
I need to source like 10x 50mm Dio gaskets so I can continue to troubleshoot...
