one thing I try to do on my threads is to post my failures as well as my successes. I like to think someone may look at what I have done and use it to prevent them from making the same mistake. I feel if I just put up what I got right it is kind of dishonest in a way.
so having said that I had another setback today. I got the thermostat housing to stop leaking and thought everything was good, then I saw coolant under the car, frustratedx frustratedx frustratedx turns out I have two more problems first I had coolant leaking out of the evaporator hose on the firewall never saw that before, but I guess when I pressurized the system I exposed the problem. that will have to wait until I get the engine sorted out however.
the next problem is probably a lack of experience problem. I decided since I was spending so much money on this build that I would use ARP head studs instead of head bolts like I have always used before. well I found out a few things first of all it would be good to understand the instructions a bit better. I watched some videos on the studs and I thought I understood what they were saying and that I needed to use this arp ultra torque lubricant on the studs. so I bought that stuff and used it. I have always used head bolts before and never had a problem but apparently the threads on the studs are rolled and the holes in the block are cut so the bottom head studs had coolant seeping up them. I have never had that problem before.
now I have not even tried to start this engine yet so the only pressure on it was from the radiator tester and I kept it under 16 psi. so I know the head gaskets are still ok. so I did some research and it seems people have had good luck removing one stud at a time and sealing them with permatex ultra black.
so that is what I did. pulled the headers back off. I still haven't hooked up the h pipe so that was relatively easy, and since I used header studs it made that part much easier.
then having previously drained the radiator again,
I pulled the back head stud. of course a bunch of coolant started coming out of the block but I had planned for that at least I had my shop vac that I put a piece of 3/8 tubing on the end and taped it with electrical tape to hold it in, it fit right down the hole perfectly and I was able to suck the coolant out with minimal mess.
then I used a bore cleaning brush and brake clean to scrub the threads thoroughly and vacuumed them again. then stuck a rag down the hole with an allen wrench to dry the threads. I did not use compressed air because that caused coolant to splash the first time I tried. then I coated the stud with ultra black, ran it down the hole, removed it recoated it with ultra black and put it back in. then torqued the nut down.
rinse and repeat on all the studs. left it set for 24 hours and refilled with water this time.
pressurized it for 3 hours at 16 psi no leaks from the studs just from the stupid heater core
I did accomplish a couple of things this week though. first I have spent a lot of money on this project so I was trying to cheap out and not do a couple things I knew I needed to, but a couple guys on modded mustangs set me straight. one guy sent me a calibrated maf senser that I installed. I was having some trouble getting my stupid cold air intake to fit, it has always fit kind of funky so I decided to do something about it. I had to cut the tubing a bit as it was too long so I put a hose clamp around it, cut it with a hack saw.
you can see how I bent the stupid thing trying to get it to go together. anyway after cutting a bit of the tubing off it fits much better.
then I swapped to a 255 lph fuel pump. I decided to paint the tank insulator and straps while I had it out
I took several pictures of pulling the tank but there are some good videos on utube that describe it pretty well.
tomorrow Dad is coming over and we will put the exhaust on, put some fuel in the tank and maybe try and start the beast. then have to see all the other little things I have to fix facepalm1
