TR2/3/3A Broken chain tensioner "noise"?

I am hearing what sounds a lot like the chain rattling against the cover at start up ,quite loud,but once the motor has warmed up the sound goes away and I don't notice it when driving. Is this what others have noticed at start up with a broken tensioner?
 
I would not think the tensioner quiets down when warmed up, probably a lifter. Did you get the lifter assembly rebuilt?

Lifters seemed OK. If the noise goes away after warm up then it's probably just the dzus screws on the bonnet that are quite loose and vibrating. Gotta fix that.
 
Chain tensioner replacement was the 2nd project when I got my car after rebuild/replace my starter. It takes a lot of time and patience and labeled zip lock bags for the bolts and screws. But it it very do-able for a mid-novice. I realized mine was broken when I discovered an oil leak in the timing chain cover where the broken tensioner wore a hole in it. PO never fixed it or disclosed it.
 
I had a broken tensioner on my 4 years ago, and it was a loud chainlike rattle - which was rev dependent. I think it rattled heavy on deceleration if memory is holding. Doesn't sound like that is your issue.
 
A rattle, when cold, that goes away warm equals piston slap. A tensioner makes a tinkling ,faint-ish
noise at idle.Piston slap is a precursor to broken ring syndrome. Followed by massive oil consumption.
Over all , piston slap wont leave you stranded, and the fix is a liner/piston set. Tensioner noise will certainly
find you parked soon, when it jumps time.

Hey Mad Dog I finally tracked down that loud metal to metal clanking noise. Turns out that one of those stay rods that hold the bottom of the front apron had come loose and was causing the banging!!!!!! Sure had me fooled. Glad it wasn't engine related. Time to enjoy the Fall driving season here. (y) (y) Karl
 
This is the reason that nylock nuts were invented. "if it can come loose ,it will".
I would suggest a secession of recreational fastener tightening may be in your future....

Just curious.Are you currently working on a British car? Do you have one as a daily driver? Karl
 
It is a race between the Tr3b and the 61 Morgan it sits beside. Both are in the final stages.
Daily driver is the 64 Mini Cooper or the 59Tr3a. Other than that I cut the lawn(when it gets deep).
Trying to sell on the 61 project car 3a....dont know why there is a Tr6 by the back door(afraid to lrt it in)
