Re: IML: Heat riser rotation?

[randalpark@xxxxxxx]

I wasn't going to jump back into this either. Now it seems to have 
gotten off track.

When the engine is off, the heat riser valve is closed (unless it is 
stuck open). When you rev the engine, the force of the exhaust opens 
the valve. Shut the car off, and it closes again, hot or cold. Heat 
decreases the amount of resistance in the spring. Unless the counter 
weight has slipped, or someone has fooled around with it, the valve is 
closed when the longer flat portion of the counter weight is facing 
you, looking down on it. If the valve is working, watch it in action 
when you rev the engine.

Also, if its working, why not allow it to work and leave it alone, 
except to lubricate it once in a while.

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,

 

Dwain
