IWE Scare
I was on my way home from work Friday and had the radio loud, but thought i felt it feel like the IWEs were trying to engage. So i turned the radio down and tried to get it to replicate but couldnt. So today i got the trusty vacuum guage out and started checking everything. Everything checked out fine but found a small leak.
When i replaced the check valves, i used a 3 way valve cause i couldnt find a straight through on at the parts store, so i just used a plug cap to plug off the third port on the valve. Last year i heard the IWEs and checked the one check valve and found that the plug cap had dry rotted and wasnt plugging, so i replaced it with a short chunk of hose with a screw in the one end. That fixed it. Well today i checked them again, and the second check valve behind the battery and, yep, the plug cap had dry rotted on that one and was leaking, so i fixed that one the same way i fixed the other one and now good to go. Whew! I really didnt want to pull stuff apart again.

Actually, it just hit me as i was writing this that i didnt check the check valves when i had them out, so i just now ran out and pulled them off again, and low and behold the check valve that had the leaky cap plug was shot, good thing i had another one sitting on my shelf. Now i should be good to go! hahaha!

That'll teach you to leave old "three ways" on! Good catch. My truck's been fine since you helped me fix it a year ago. I'll never forget the first time I heard that left front buzzing...I thought the tranny had blown or something!

It is kind of wierd, the plain straight through check valves are often not on the rack. I could only find one when I started my trouble shooting and repair. I seldom see them in stock. I didn't use the one I got, but put it in the glove box...
