ok so i replaced the t-stat and the pcv valve and the car ran good while it was cold. M cuz and I took the car up to the bar to grab a couple of six packs and when i pulled in the parking lot the car started smoking, so i turned it off. After I came back out and started it up it started smoking again, I went to leave and the car really didnt have any power in the low end pulling out, the car putted up to speed,and was blowing alot of smoke out the exhaust, when I got home I pulled it in the garage and let it run for a little bit, I opened up my hood a couple of mins later and tapped the throdle control. the car stalled out after that and it wouldnt turn back over.

I check my plugs for to see if they were fouled out but they looked fine. there was steam coming out of the hole were the plug was pulled and also out of oil cap, there is some blow by on the oil cap but about a pinhead mont on the dipstick

the car didnt not over heat at all, is it posible that i fried a ring?
