So I bought a 84 camaro not too long ago, the original motor had a rod knock it it so I bought a rebuilt motor (350 sb) and had it painted and dropped in aswell as the previous motor being pulled. I had my buddies dad and his brother drop it in at their shop on a weekend as a side job for them and they did it within about 6 hours i'd say. Well i have electric radiator fans that wont wire up to the ignition or else they blow a fuse, and sometimes my switch will go bad and burn up, then my fans shut off and over heat the motor.

This has happened twice and i have now bought a 15 dollar switch which hopefully will hold me off until i invest in better fans or a water pump mechanical fan (Which im unsure if I want a mechanical fan because they make your motor work harder). So I ovee heated it once and oil mixed with the coolant, but I had one of the guys come by and check on it and he said I was lucky as hell and that nothing was wrong with it. She started tigbt up, he topped off the coolant, and that was the end of that.

Now bare in mind with me that the motor, when turned off too quickly (since I got it) it will start banging and jenking around pretty roughly. So I seemed to have figured that out, i called a shop and the guy told me he had an old el camino that did the same thing. He told me put higher octane gas in and i have since, 91 sunoco fuel. And it has been alright since. Well the other week i over heated infront of my buddies house about a day or two after changing my oil, but my newer switch has gone out while I was idling infront of his house and talking with him. Fans stopped and before I know it resevoir cap shoots off and theirs oil in my coolant, i let it cool off for a little, topped it off with coolant and drove it home which was right around the block thank god. That night I went up to the auto parts store, bought a buncha distilled water, and 2 half and half coolant bottles and an expensive killswitch. So I came home, flushed the radiator, put the new switch on and she was running like new again. No engine sounds, no white smoke out of exhaust, no bubbles in the coolant. So for the next two days before I would drive Id turn her on, make sure everythings working,* made sure I wasnt loosing any coolant. And I wasnt. Then I started to drive her like I normally would again.


About two days ago I was driving two cities away to go pick something up from my buddies so I took her on I-94 and drove about 5-7 miles from home. When I got off the freeway, i was driving down the road and i got no response from the gas pedal, RPMs dropped to 0 and my motor started banging around like it would when I had the 83 octane gas in it, except this time it wouldnt stop, i popped the hood emediatly and hopped out, unscrewes the car battery and unconnectdd the wires out of panic. It didnt work! The key was out of the ignition and the motor was half ass running without the electric. Idk if this was the mechanics fault for not taking the required ammount of time to tune and make sure everythinf was running right on the motor or what. But the motor was running, all the pulleys were spinning, accept the motor was making banging noises,then after about 40 seconds it stopped and white smoke puffed out from the carb and through the air filter. Then the motor wouldnt even start! Oil mixed in with the coolant, but heres the catch. My fans were working! Everything was normal, water temp at around 180-200 and my oil pressure was between 20-40.* So i possibly had a blown head gasket already, because of the previous over heat at my buddies house, but i am not sure. Nothing like this has ever happened. Brand new motor, bout 5000 miles on it. It was rebuilt right, and no it does not have a rodknock or anything. She sounds beautifull when ran.

This whole situation is mind boggling me, no one else in history of the internet has ever posted about having this problem. I know now forsure that I have a blown head gasket, but does this sound like the engine has even more extensive damage? Did the mechanics who dropped this motor in not do something right? After they dropped it in for me they pretty much said come and get it and i picked it up and they never touched it again. They did somewhat tune her and ready the motor for driving, but idk whats wrong. (Motor was dropped in about 6 months ago, and I took it easy on her till she hit about 1500 miles, also had the car tarped up sitting in drive way for the last 3 months cause of winter)
