Hey- I was tightening my body-frame bolts (and boy did they need it) and pulled the air inlet valve off to get to that one bolt in the pontoon. I noticed that it was still mostly closed allowing hot air even though it was 70ish. I then noticed that it didn't moved when I heated it up. Another aged part to check, guys. There is a little indicator on the side that tells you what air the valve is letting in at the moment, so you don't have to remove it to check. There not too expensive at my local part store (www.delorean.com) at about $58, but unfortunately they're closed on Saturdays and Warren, James or Stephen have failed to give me their home numbers for weekend parts. :D So I pulled it off, fiddled around with it, lubed it, and freed it up some, but it still wouldn't open fully to cold air. I adjusted the plastic nut and got it to where I think it will operate better. I tossed it in the fridge and noted that it closed fully, but it sure is slow to open up again. What is the replacement schedule for these guys? What about regular adjustments? -Kevin #4687
