Hi, Folks,

Long time no post!

I see where British Parts Northwest  ( http://www.bpnorthwest.com ) has 
this new 25D4 distributor for $145. It's a drop in replacement for TR 
3-4a and includes everything except for the dizzy cap.

Almost seems too good to be true. ( Danger, Will Robinson!) I'm not sure 
if if you could have your original dizzy recurved for that. Anyone tried 
it? 

Is it a Lucas item ? If it IS a Lucas item, is that good or bad?   <wink>

Next subject: Rocker Assembly.

My rockers seem noisy to me even after I've checked my valve 
clearances....twice. ( Yes, I backed off and re-torqued the rocker arm 
pedestals too. ) This assembly has about 110K miles and I'm getting that 
pronounced 'sewing machine' sound from the valve gear.

ISTR several listerati have used 'Rocker Arm Specialists' in Anderson, 
CA. That correct? They're showing a TR 3-4a rocker assembly rebuild on 
your core for $165.

Do they replace the shaft or just rebush the rockers? ( I'm assuming 
they rebush the rockers at the very least )


When it's all done, does it still sound like a sewing machine, just a 
quieter one?

Happy Motoring!
