All,

I am putting the emission control system on my (new to me) 1984 244, B21FT, auto trans back together. My question is this, I have installed a new pressure switch, it was totally missing and is located on the center of the firewall, it signals the ecu to hold the frequency valve duty cycle at a fixed setting during accelleration. There is a delay valve that should attach to the pressure switch, I have a new delay valve, which way is the valve oriented one side of it is yellow and one black and it seems to move air in only one direction. Any thoughts?

Second item, the rear of the hood is about 1/4" above the fender edge, the hood closes and latches tightly. Is this a bent hood or an alignment issue, and how do I correct it? As always thanks for any input.
Thanks,
JD

The hood hinges are one of the few areas of the car that I feel somewhat qualified to comment on.
I also had the same problem on my 1986 240 and had plans on trying to adjust them out.
Now before I had the opportunity to do so, the drivers side hinge actually broke on me one day when shutting the hood so then I was forced to buy a set of new hinges off of Evilbay (I'm sure they are also available at any local junkyard).
Well when I put the new hinges on my car they did need some adjusting done to them. If you look at the hinges you have slotted openings which allow you to move the hood front to back and also down and up (on the side by the windshield). It's really about as simple as it can possibly be but I would suggest getting a helper to hold the hood in place as you loosen the bolts.
In my case I had to lower the hood to the bottom of the slots (a few different times between tests)until I got the right up/down position. After that I measured the gap on each corner of the hood and adjusted the forward/backward adjustment until the gap was exactly the same on each side. Then I went to the front of the hood and adjusted the up/down adjustments on the rubber bumpers so that the hood closed evenly across the front of the car. The only REAL piece of advice I can give you is to make sure you have the grill out of the car before doing anything, in case the hood would lock down because of bad adjustment. That way you can access the locking mechanism much more easily. Also, the spade that locks in on the front of the hood can be screwed in and out for proper latching. This is also an adjustment that needs to be done. I also drew around the hood hinges on both the hood and the fender so that I always had a reference point to go back to. All in all it took about a half hour and now my hood fits perfectly.
If you do have bent hinges I would probably just go to the salvage yard and pull a set of them. Won't take much time to do and the cost should be negligible. Man it feels good to be answering a question other than begging for help. :-)
Hope this information helps you out.

Hi JD,

The black cup side goes toward the pressure switch, the yellow disc side away.

I believe the most common reason for the hood misalignment is a bent hinge, caused by lack of lube. This can progress into a bent hood as well, when forced. A replacement hinge is better than taking the kink out of the one you have, which will tend to bend again in the same place.

What's the definition of a will? It's a dead giveaway.

Thanks Art, this should be an interesting restoration as it is missing so many odds and ends, I need to post some pics.
