Ok, I've got a 914, with an unknown engine (serial is for RoW 1.7) that was rebuilt "several years ago". Just now I was shuffling cars... started it up, backed it down the driveway. I let it warm up for a couple minutes and shut it off. Then I went to move the MG so I would have toom to park the 914 next to it. The 914 was off for maybe 5 minutes. When I went to start up the 914, it immediately had a loud clack/knock. I drove it up the driveway and parked it next to the MG, and it made the noise the whole way. (about 75 feet) I shut it off, went to get the camera to record some videos. Then I started it up, and recorded these videos:
First is idling at about 1400 RPM, for 30 seconds. Second is idling with a few blips of the throttle, also for 30 seconds. The videos are 2.7 megs each. Thanks! |
