So 2 weekends ago I took the 914 out for a weekend drive. She was running great but on the way home the exhaust volume rose quickly and it started to sound like a loud lawnmower. I drove it 5 miles home and parked it till today.
She still starts and idles normal aside from the sound but when looking into the engine bay on the driver's side I noticed what looks like a backfire coming from a small hole just left of the air intake runner. I've attached a picture with an arrow pointing to the hole. Anyone know what could be causing this? Engine is a 2.0 fuel injected from a 74 Thanks in advance for any help or suggestions.  |
