MG MGA - tappet noise
|Can anyone tell me if fitting an alloy rocker cover will lesten the tappet noise, thank you, Vin.|
|Vin, there was a discussion on tappet noise a little while ago and the best advice I received was to run the engine with the rocker cover off and place a feeler guage under each tappet. This quickly identifies which tappets are very noisy and they can then be adjusted down a little. B series engines do tend to have noisy tappets its part of their charm as long as its not excessive but if you want a really quiet engine then yes an ali' cover will reduce the noise level and as you suggest its one of the reasons that owners fit them.|

|Hi Vin, I took the alloy rocker cover off mine when I bought it and replaced it with an original cover - I cannot say I noticed much difference in tappet noise between the two .|
|I succombed to the same snake oil pitch when I put an aluminum cover on my 1500 during restoration. My 1st running MGA was a 1600 and I was not impressed hearing the valve clatter all the time. I have to admit I didn't notice much difference once I got the 1500 up and running. |
Unless you want the shiney bits for looks, stay with the stock cover.
|Vin, check for wear on your rocker shaft and rockers by giving each one a twist and seeing if they move adversly. I had a lot of 'tappet' noise on mine but cured it (as much as you can on an MGA) by replacing the worn shaft plus two rockers.|
