Blown Headgasket Confirmation

[Clinical]

So my car has had an issue pushing coolant but never overheating, and I've been pretty sure it was the headgasket.

Then after a tuning pull the other day it started heating up so I let it cool, then took it home.
It keeps idling funny, so today I was checking it over again, I see coolant pissing out the back of the motor. It looks like right around where the coil pack sits, except a bit lower.

I'm assuming I just finished off my headgasket? I can't think of anything else tiny in that location that would be ferrying coolant

Sounds about right. I think a compression check should be able to identify if you have a blown HG pretty quick. I can't think of anything else in that area either that could cause that issue.

Well I'm not surprised. Running 2-3 years at 25psi on E85 although conservative timing, all on a OEM headgasket will take its toll!

MLS here I come!

That seems quite impressive for an OEM haha. But let us know what you find!

No compression at all on the compression test possibly means blown hg correct?

Ultimately, it could mean many different things. In this application, I would say yes. If the compression check failed, the likely cause would be the HG being blown. It could also be things such as bad piston rings, bent valves, or leaking valve stem seals. Just depends on the situation.
