I bought a 93 rx7 project car. With possible blown engine. White smoke was pouring out of the tail pipe. After reconnecting the map sensor it stopped but it would still let out a puff of smoke when I shifted into the next gear.

Then I replaced the twin turbos. Because they only worked 40% of the time.
And I probably screwed up the vacume lines after the 4 day process.

And I was having overheating problems. I pressure tested the system and it held.

So I let it sit for a few months.

I just checked the oil and it looks like chocolate milk.

Do I have a blown engine?
where do I get a rebuilt engine? I live in north jersey.
What single turbo should I get? I dont want anything to crazy just reliable.

Sorry for being novice Im sure im leaving something out.

 

Chocolate milk sounds like a leaking coolant seal. Smell the mixture on the dipstick and see if it has any kind of sweet smell to it. As for a rebuild, talk to Rich (GoodfellaFD3S). He's from Jersey and should be able to help you with that.

 

The spy hunter smoke screen is also a tell tale indication. Sounds like blown O ring to me.
