I'm a bit stressed after all this and hoping for some help!
Have 1990 325i with M20 that was idling a bit low due to a vacuum leak. It was also just absolutely disgustingly dirty, so I decided to remove the IM and VC to paint and replace necessary gaskets. Off the top of my head I replaced the IM gasket, VC gasket, PCV hose, and vent tube O-rings. Got it all reinstalled and it idled perfectly and ran great! Immediately took it down again to replace the drivers rear trailing arm, and along with other priorities getting in the way, made this a several month long downtime.
So this morning I finished up the trailing arm and hopped in the car to take it for a drive and she ran great! So I decided to quickly hop on the freeway for 1 exit to make sure it felt good at speed, and head back home. All went well until I exited the freeway, stopped at a light, and saw steam seeping out of the engine bay! Shit! I look at the temp gauge and she's overheating!
Pulled over, let it cool some, made the rest of the short drive home, and immediately started looking into the issue. So first of all, I realized at this point that it was low on coolant which I'm *hoping* was the cause of the temp gauge reading so high... basically an air pocket at the temp sensor. There was steam pouring out of the engine bay, near the front drivers side of the engine and even a noticeable stream of coolant pouring from somewhere under the IM.
Given this description, I'm wondering if there's an obvious place this could be coming from that may even be a result of the IM work I'd bee doing? Thoughts? I'm leaning towards the thermostat housing myself, but need to figure out moving the fuel rail to get it off.
