^ I could only assume so...my point was that head gaskets aren't intended to save your engine if detonation comes around...I specifically went with the OEM headgaskets to artificially give myself a weak/fail point if old man detonation comes my way!
Possibly... cooling spewing out of the reservoir tells me that the coolant passage is blocked...that would be losing coolant...
you'd get milky oil if coolant is in the oil. Evaluate what has higher pressures? What's the pressure of in-cylinder combustion? I think ballpark spikes around 1000psi, while the water pump pumps coolant at 10-15psi ... so combustion is being pushed out of the cylinder (via a fouled head gasket) into the coolant path at a much higher rate and volume than the coolant being forced into the engine - via the the same fouled gasket during intake stroke or times when the cylinder pressure is less than ~10psi.
The small amount of coolant that does seep into the cylinder is being burnt off with the combustion and out the muffler - hence the sweet smell.
OP, if it's not too late, take a very very good look at the coolant that came out of your engine - do you see any burnt particles floating in the coolant?
Does he have any of those symptoms?? He said no milky oil or anything beside sweet smell..
Are you actually losing coolant?
He is gona build it anyway but I would like to find the root of problem so you have worry free build
How do you test coolant for combustion gases?
