ok so i have been having issues with my v-6 motor missing after it starts for a few seconds, unless i push the gas and then i get a black puff of smoke out the exhaust pipe and then it runs fine, well i also found that i was running low on coolant so i filled it up and 2 days later same thing, so i figured it was head gaskets where bad but i took plugs out and didnt see any cylinders that looked wet none did, and also i went ahead and pulled, the fuel injectors out to see what they looked like and 2 of them had oil covering the tips, im trying to see if i could be a bad fuel injector and maybe a leaking pipe somewhere else that i didnt see, any help would be great.... thanks

 

well i said screw it and pulled the heads, and found one of the cly had water in them. oh well guess i found my issue, i have gone and ordered head gaskets from toyota,
