Re: IML: Heat riser rotation?

["Frederick Joslin" <fljoslin@xxxxxxxx>]

Hi Dan:

I just went and loosened the hose clamp that I have on my heat riser valve.

The clamp is holding the counter weight rotated fully counter clockwise with the weight at the top.

After I removed the clamp the counterweight rotated clockwise (looking at it from the passenger side fender) and hit the stop.

I would assume that this is the valve closed position since the engine is cold.

I also assume that this is the original exhaust manifold and if not that they probably did not change the heat riser valve on BB manifolds.

Now I am confused (again!).

Didn't the general concensus think that
(looking at it from the passenger side fender)
the heat riser opens when turned clockwise (in
the "down" position) - and closes when turned
counter-clockwise (in the "up" position?

I hate to open this back up again but, I want
to wire it open correctly. My engine is a '67
440 from an Imperial (which I don't thinks
makes a difference).

Fred,

 

Thanks for the quick reply. I have the counterweight rotated all the way clockwise against the stop looking at it from the top. I guess this means the valve is then closed and directing exhaust thru the intake manifold. Luckily I just did this "correction" as some of the letters stated that the counterweight needs be rotated clockwise toward the front of the vehicle. Luckily I've only had it out once since rotating it, maybe 40 miles worth. I'll rotate it towards the rear of the vehicle in the morning. hopefully this will lock the valve open bypassing the intake manifold. Thanks.

 

By the way, do your sequential turn signals function correctly? I'm having a bear of a time with mine.Only two of the three taillights sequence on either side when activated and the emergency flashers just stopped working.. Thanks again,
