While replacing old vacuum lines I had the end of the delay valve and the end of the gray switching valve break on my 85 RX-7. Fixing the end of the delay valve was no problem, but I cannot get at the switching solenoid to glue the end properly. Any suggestions on how to repair this would be most appreciated.

 

take a picture of what you need and post it. i probably have one laying around i could give you for the price of shipping.
pm me.

 

It looks like JB Weld took care of it, but now it s a bit harder to start when warm.



I can't post my pic.

 

JB is not holding. Also when thngs were attached, the car was harder to start. This is the gray solenoid (switching), the third from the left when looking from the drivers side of the car. What does this solenoid do?


P.S. I cannot upload the pic as it is too large. If anyone wants to see a pic I can send privately.

 

use something like imageshack to post it

 

It is the solenoid directly behind the oil filler pipe.

 

Well, there are a few options to fixing this.

The first is rats nest removal. That particular solenoid is not needed to run the car if you do a complete emisssions removal.

The second would be to get a good sharp object, don't cut the vacuum hoses but use the edge to push them off the attachments on the solenioid, then once things are detached from it, use the clip underneath the soleniod (careful it's brittle with age) to detach it from the holder on the engine, remove, glue, reattache everything.

I do believe I broke mine while trying the rats nest removal as well. The far right one was the only one needed if I recall.

FOr my knife removal method a screwdriver works as well, you use it to break the seal between the old rubber and plastic, very gently, this makes it much easier to slide the old vacuum hose free.

 

My hoses were so stuck to the fitting that even after it broke the hose had to be cut to free them In fact, even after cutting the hose, it was firmly stuck to the fitting, leaving a good amount of rubber on the fitting. My hoses are not pliable at all.

 

I guess the other option is to totally cut and replace all your vacuum hoses, which is a good thing anyway.

 

That is what I am doing (with some apprehension). However, the question becomes what to do with the gray solenoid? I have the end JB-Welded again. I have doen the same with the delaying valve, but have no vacuum flow at allin any line to or from that solenoid. What does it do? How does it affect the running of the engine?

 

Well I removed all mine except one when I removed emissions from my car. I know somewhere in the FAQ there's a link that has the entire vacuum system to what goes where on the engine. You could try super glue because it is a plastic it may work better than JB weld would.

 

Ok, the link is great!. I now know how to remove a single solenoid. Now, does anyone have a gray solenoid laying around?

 

I've got one I'd probably be willing to part with drop me a pm.

 

I am desperate for a gray solenoid for my rats nest. Please help me.
