[Spridgets] Blanking sleeve and blocked bypass again...

[Dean Hedin]

It's not called a "restrictor plate".  It's called a "blanking sleeve". Moss
sells them.
 
Clearly you are not following.

The BMC Special Tuning Guide states...
"Assuming the thermostat is working correctly, overheating can result if it
is removed without fitting a blanking sleeve 11G 176 in it's place.
Alternatively, the bypass connection between the cylinder head and water
pump may be sealed on 'A' series engines."

It's not that I want to run without a thermostat.
My situation is that the previous owner on the 1100 head that I just
installed blocked the bypass.
At this point I'd have to remove the head to unblock it and I'm not up to
doing that.

Now, I don't think it is safe to run a thermostat if the bypass is blocked.

I think I provided a good reason why it's bad to do this.

I just looked at Moss's catalog and it looks like the 1275 cars have the
bypass too.
The 1500 design is a different animal (but I'll bet there is still a bypass
mechanism)

And no, I'm not trying to pull anybody's chain.

Now, you explain to me why the bypass "did'nt do all that much and was'nt
needed" or else I will think you are pulling everyone's chain.
You can start by drawing yourself a little schematic of how the water flows
through the A series cooling system.
With any luck it should then become clear to you why the bypass is there.  
With a little more luck it might become clear to you that just about any car
with a thermostat must have (and does have) a bypass mechanism.

Yea, great idea don't use a thermostat, all they really do is bring the
engine temp up to optimum level faster.  Who needs that?  The reason there
isn't a bypass on the later cars was because it really didn't do all that
much and wasn't needed.  Use it or don't makes no difference. You do know
where to get the restrictor plate to replace your thermostat?  Really I just
think your pulling my chain, but good luck whatever you decide to do.
