MG MGA - 1500 tappet setting
|My 1500 engine is very noisy with a 17 hot setting. Rockers have been reface. The 1600 setting is 15 hot and has the same cam. Did they realize .017 was more than needed, but did not include a new setting for the 1500? I have set tappets on many engines so I do know how. What say you all? Can I set them tighter?|
|are the valve end of the rockers smooth. If they are worn there may be a groove that would be bridged, giving a false set. The rockers can be re-dressed.|
|He said they are refaced, so I assume that means the business end!|
Why set them hot? By the time you get to No 8 the valve stems have all cooled down and everything is the same temperature.
You can get noise from a worn rocker shaft.
|Dave, check that you haven't got wear in your rocker shaft or worn rocker bushes. Both of these will give you abnormal 'tappet' noise. How do I know?!!|
