wondering if n e 1 knows what i should expect out of this engine. i got it and the charger was unhooked due to a idler pully gone..and the belt gone. i drove it about 75 miles, i knew from the git go that it had no compression in the number 4 cyl. i thought valve at first...then im thinking, a valve wont really cause the blue smoke coming out the back. its not terrible...but it does burn oil. so now im thinking piston. i am pretty sure she overheated it and it needs at least head gaskets and everything above it lol. but i want to be prepared for wat it actually maybe, ive had people say it could be intake gaskets....far fetched....cracked head....yea.... anyone experience this, i mean the car didnt drive bad just a miss, no noises.... i kno there is alot of vacuum when i take the oil cap off. it feels like it is blowing, but when u put the ap close it sucks it right to it.....
