Just found this site. Wow. Great info. I have had my 72 914 for 30 yrs. Restored it 10 yrs ago. Still all original--fuel injected. Since then, it has been driven very little (unfortunately). In the last year, I have started getting a popping or backfire on decceleration. It is getting worse and worse. The car drives great and strong other than this annoying habbit. I heard about the exhuast leak possibility and put my had under the car while it was running. I can feel airflow under each heat-exchanger to head connection! Is this normal? I don't understand how ALL could be leaking. I used the copper rings when I connected them 10 yrs ago. Could they be going bad?? I need an expert!!

Just bought used S/S heat exchangers on ebay. Also new nuts and copper seals. I am going to replace my old heat exchangers to try and eliminate the backfiring on decel. Does anyone have advice on what to do about the broken stud? Should I pay to have it replaced, or cut the exchanger mount down to allow enough of the stud to poke thru?? Not sure how complicated a task it is to replace a stud.
Thanks in advance for the help. |
