so i swapped in a ka24e into my shell. hooked up everything and went to go fire it up. and its pouring out a massive white smoke like a rocket taking off. ill let it idle for awhile and it calms down but not entirely. step on the gas and a shit load of smoke still comes out. i pulled out the plugs and it was fouled. also remove all the plugs and turned the motor over and water like substance was coming out the spark plug holes. any ideas? to me sounds like it running pig rich.

new o2 sensor
new spark plug/wires
new coil
new cap/rotor
new coolant temp sensor
new maf

I'm no expert but from what I've seen personally it is probably a blown head gasket... Watery substance you're seeing is probably coolant.

so i ran it without the plugs again and caught some of the liquid shooting out and it taste like gas. stuck open injector maybe?

Do these test to check for a blown headgasket, or your rings might be fucked also.....
Watch your engine temperature gauge. If your car is constantly overheating it may be a symptom of a blown head gasket.
Check the engine coolant level. If the car is constantly losing coolant, it may be because your car's coolant is leaking from the cooling system into the oil pan. This happens when the head gasket is blown.
Check your car's oil level with the oil dipstick. If you notice froth on the dipstick, there may be coolant mixed in with the oil due to a faulty head gasket.
Watch for sweet smelling white smoke with water droplets coming from the exhaust pipe. This could be a sign that the head gasket has been blown off

It sounds like its running rich. Id check the injectors, be careful and don't flood the motor!!

Sounds to me like an old, tired KA in need of a rebuild.

The KA that came with my car smoked like a chimney when sitting at idle on first startup... then blew out a massive cloud whenever I'd sit at a light, then take off... It ran smooth; but had very little power... Just a tired old motor. Happens.
