Odd rattle from engine '89 120L

Recommended Posts

Hi all,

 

I have an '89 120L, and it's developed this sound that's almost like a heat shield loose in the rear. It starts after the motor is warmed up, and during mid range revs. So idle is fine, and what passes for WOT is usually fine too. 

 

Any ideas? I thought maybe it's the exhaust rattling off the frame but it's not.

I'll have a look, I didn't see one since the exhaust is so short, but that's exactly what it sounds like. Odd that it only starts after warmup :p

@Krtek - I'd expect something because it's a non cross-flow head, but that's also why it's hard to see since the shield would be between the exhaust and inlet manifolds and under the carburetor and air cleaner.

I figured it out; The 3 bolts that hold the manifold on were loose. 

 

I put my foot on the muffler when it was running, and noticed there was play there. Runs good as new. 

 

Thanks for all the help!
