Hi everyone, Upstate NY guy here with a 1989 fox body 5.0. I bout it 2 years ago already built. its a 306 with edelbrock heads, edelbrock tb, pacesetter headers, not certain on the internals. no heat or a/c and no power steering. ran great up until recently it started to studder and pop and spit if i tried to get in it a little. so i took it to a shop they did a compression test and told me it needed a head gasket. well my buddy has a shop and to save money i figured i would dive into this and with his help get it done alot cheaper and i would have a little fun doing so! so i drove it over there, we stripped it down to the block, during that process i found out i had a bad injector and the last spark plug in the rear left side looking at the motor was in at an angle and stripped out a bit, so my buddy knows this guy that does machine work and he told me to take the heads to him to have them checked out and to fix the spark plug threads. Meanwhile i ordered all new plugs, a new injector and all the gaskets to put the motor back together. The machine shop guy called me, said the heads were not warped or cracked and he could fix the spark plug threads no problem. He said all the chambers were flowing different numbers and he could do whatever to them and make them flow the same. so i gave him the ok. Well a week later i get all the gaskets my injector the plugs and my ARP head bolt kit!, The machine shop guy calls and said that the heads are all done and turned out sweet! ($450.00 later) but they did look nice and i was happy. so we cleaned everything really good put it all back together, new oil and oil filter, i was tightening the thermostat housing bolts and i went to much and POP it cracked (damn it lol) 9 dollars later and a trip to the parts store i solved that problem. so now its all done and ready to fire up, turn the key and she fires right up, then stalls almost right away. fire it again this time runs for a few seconds then stalls, maybe 1-2 more times and she stayed at a rough idle then i messed with the little screw on my intake and she smoothed out, all my temps were good oil pressure was good but it was smoking white smoke like crazy, so i took it for a drive and came right back because the temp gauge rose up and down almost maxing out into the red zone, and the car was very hesitant, no more popping and sputtering but like a ball rolling out of round, only when i would kinda get after it a little though, so i pulled it in the shop, we popped the hood and it is still smoking really bad (white smoke out of the exhaust ) and there is a puddle of oil (possibly coolant mixed in but maybe not) to the right of the thermostat housing (maybe on top of the timing cover?). Also there is a hex-head plug/screw on top of the thermostat housing that seemed tight, yet some water dripped on it from when i popped the hood (it started raining)after pulling it in and there were little bubbles forming around it? i tightend it more but it still does it a little and i didnt dare tighten it again i dont really know if its suppose to do that or what lol. when the car is idleing and i hit the gas while its in neutral the rpms go up to 2 grand maybe more and then i let off the throttle and it will come down slow then shoot right back up again on its own. also if im driving it and am coasting at any speed in neutral it will also rev up to around 1800-2200 rpm on its own and kinda stay there until i put it back in gear, but i can tell if i put it in first its still revving high as soon as i pull it out. but it doesent do it all the time. so i am in need of some help. i have a video i am going to post of the idling issue (if i can figure out how to post it) and i will get pics up and more video of the other problems soon.
thank you all very much!
