Uh oh! My f20c has become a steam machine

What are you looking to spend on a shortblock?
I might be able to get you connected to a new AP1 shortblock source (long transit time though).
I might also be willing to part with a soon to be out of one of my S2000 new AP2 shortblock (2000ish miles).

Blew a head gasket. It still runs sooo smooth, but blue smoke and steam, and 148k miles. I think the engine is dooooone. Anyone have an f22c low mileage just waiting for a new owner?
I called inline pros and spoke to them at length. If I was 100% sure I’d get a perfect new build I go with them, but I read a thread here that was less than flattering.
Any thoughts or input? I’m on the fence in every way: f20 or f22, rebuild or source low mileage swap, rebuild all or just head.

There'd be more to it than swapping the gasket, I hope no one actually blows a gasket then just swaps in a new one without any machine work. Bring it to a machine shop, check valves and guides, resurface the head, etc.

Additionally, dont be afraid of sleeves. Your understanding is a bit incomplete. The reason people run looser tolerances on sleeved blocks is because the piston is forged and expand more. The extent the piston expand (and thus the tolerances) depends on the composition of the forged piston and the amount of power (heat) you anticipate producing. If you want a tighter (quieter piston) tolerance run a hypereutectic pistion. Sleeve expansion is a non-issue. Apart from the FRM motors ALL other honda engines use dry iron sleeves. I've run dry sleeves for years at 20+ lbs. Any competent shop can do dry sleeves and their power capacity is plenty for a street car.

Best advice here.

I've always been curious as to why no one runs dry sleeves on these motors. Its much cheaper and gets the job done imo.

Why do I never test first. I kinda just wanted an excuse to get a new motor. I pressure tested the system… it’s fine. Probably a cold day causing lots of exhaust steam (there was no sweet smell).
I’m going to pull the thermostat, test and swap if needed.

Well, it was either the water pump or the thermostat. Zero issues after replacing. The steam part was likely a freezing cold day, and maybe it need valve stem seals.
Side note: anybody’s wanna buy a fresh F22 with ARP head bolts, lol. I kind of have a spare now.
So now I have a spare motor, spare transmission and a turbo kit “just in case”. What is wrong with me?
