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!!

Examine the "ears" on the SSI's when you get them. People tend to overtighten them and bend/break the ears.
Also make damn sure you remove the old copper gaskets from the heads. Be prepared for a fight. I use a dental tool with a "90" in the end and pick them out. When reassembling ... use hight temp orange silicon on the copper gaskets.. only the side that goes to the head. This will help hold them in the head while you place the heat exchanger in place (otherwise they can fall out as you start getting close to the head with the HE). I'm betting your exhaust leak is in or around the muffler... look for black soot around the muffler flanges. B |
