I've got a rather loud rapping noise from my 4-banger in a new 914 I bought. It sounds almost like the worst rod knock you've ever heard. So loud that you can't even talk over it at 1200Rpm.
It generally doesn't make the noise at low idle. So asuming I had an internal engine problem (as everything looked good under the valve covers) I began pulling the motor. I descovered that the front mount that attached to the case and the cross support brace was VERY loose on the case. At least one of the 4 bolts is missing, that I can see, and the others are at least 1/2" out of the case! With the engine removed I can swing the cross brace about 2" at the ends. I am wondering if anyone knows if the case bracket "could" collide with the back of the fan housing? I will post my findings when I get the shouding and fan assembly off. Thanks -JR- |
