Note- yes, I realize this has been covered in previous posts however I am looking for additional info.
I recently acquired several new cases for my rebuild. I am trying to remove the head studs. I have an EC case, a EA case and a bus case modified for a 914. I was able to remove the studs on the EC case without major problems however the case has some issues. I do not plan on using the bus case. The EA case seems the best but I can only get 1/2 of the studs out. I have tried large amounts of penetrating oil over the past few days. I have tried to heat the CASE with a propane torch for about 2 minutes. I am double nutting the stud. I have tried to grip the base of the stud with vise grips however I cannot get the vise tight enough so it doesn't spin (due to some corrosion). I am using a 36 inch wrench so I get very good leverage. Any ideas? I can put a bit more muscle into removing the studs however I am scared that I will break the stud since it already seems to twist quite a bit. Should I heat the case longer? I have broken a head studs on a EC case in the past and it is not fun trying to remove it (I was actually able to drill the stud out but not fun). |

I just came in from working on the head studs. I still can't get the bastards off. I heated the case for about 10 minutes. The case was super hot- still wouldn't budge. I am going to try double nutting with an impact wrench tomorrow. If not, I will buy some MAPP gas.
I am having a hard time finding a way to tightly grip the base of the stud to reduce the torsion. Vise grips are working out too well for me. I guess my next question should be- do I even need to remove all of the studs? The reason that I was going to remove them was to check for collapsed registers. Is it possible to check for collapsed registers with 3 out of 4 studs per cylinders removed? The case is a 1.7l case with 20k original miles. Also are all t4 studs the same regardless of the engine? (with the exception of EMW and ARP studs). Can I interchange studs from one T4 engine to another? |
