Momentary Sputtering 3RZ

@Mod @Stephen1231 I was able to pull both the manifolds and all the junk involved today. I had the exhaust manifold off in about an hour then had to go run errands for several hours. I came home and started pulling the intake manifold off. For some reason, when I pulled the plenum off the studs, This started happening. Coolant and water flowing from this cylinder. I think it's now safe to say I should pull the head . When I separated the down pipe from the cataylitic converter, there was a small waterfall of rusty water as well. The inside of the intake manifold is coated in oil, the ports on the intake head are FILTHY. Is that normal? Is it related to the fact that my cooling system is now mostly H2O and not so much Antifreeze? Any thoughts will be appreciated. Thanks for all the help so far. Everyone has been very helpful in getting this issue resolved.

 

I take it you did not drain the water from the system/radiator before pulling the intake manifold. If not, you might have loaded the oil pan with water since it has had time to sit and seep down after that cylinder was filled with water. A couple back to back oil changes should get most of that out.

Regardless, It looks like that cylinder has been pumping water out,,and possibly the one next to it as well that is slightly white on that port wall. The water fillage could have also pumped past the open valves as it also took a glug of water.
