Engine tick/knock
I'm really hoping someone on here can help me with this one.
Two days ago I was driving my 944 ('87 turbo) and had a full engine failure. The car shut off and I lost power immediately almost like it had stalled. On the side of the road I let it cool a bit and tried to restart it after a good hour or two but it was no good. After noticing that I had no tach bounce, I found that one of the reference/speed sensor wires had ended up sitting on the backside of the engine and the wire had been burned through. It was an easy replacement- a new sensor and the car fired right up. Today I started the car up again and there is a ticking or knock sound coming from the top side of the engine- it sounds like it's around the 3rd cylinder.
Can anyone give me a direction to check what may have happened? Could one of the valves have been damaged on shutdown or something similar?
Thanks in advance

I noticed it right after I got the car home the other night and I know it never made that noise before. I was hesitant to run it long enough for the motor to warm up in case something had been damaged on shutdown- I didn't want to make it worse
I read some of the other threads on here and decided to run some seafoam through it and then change the oil. It seems to have quieted down now so maybe a lifter was stuck or something. I'm going to drive it to school today so the seafoam can work through it a little more and then change the oil tonight. Let's hope that is an end to it
