Ran across a cheap Civic, it needed a head gasket and radiator. I've done at least a dozen on various vehicles over the years. Figured it would be no big deal.
Changed the timing belt, water pump, tensioner, all the gaskets, new spark plugs, had the head machined to make sure it was level. Replaced the radiator and the cap. Fired it up and it started and ran fine. Bled the cooling system with the front jacked up, heater on full blast until the level stayed filled with no bubbles, took about 20 minutes.
Went for a drive and after 10 minutes or so of driving I saw a rather significant amount of steam, turned out it was coming from the radiator cap. It wasn't overheating, I figured bad radiator cap. I've seen it happen. So I got another one, same results, drove for a bit and again, steam gushing from the radiator cap, but no overheating. Oddly enough, not from the reservoir. Swapped radiators figuring maybe my cheapo $40 eBay special wouldn't seal and again, same results.
Anybody got any ideas what else it could be? Did I screw up my first head gasket in over 15 years?
