After 7 years of using a large screwdriver to pry up the cover, I've had it. Why did GM install large screws to button down the cover and no way to open it ? I've never worried that the cover will just pop open on its own so I have never screwed it down.Alas, along came my electrician friend with his router and he enlarged the existing the holes and I installed ACE Hardware circle pull up rings and forever more to open the HEAVY cover I just pull on the O rings and up comes the cover. Why didn't I do this 7 years ago and why didn't GM engineer a simple solution ? Just curious, what have others done

I think those "large slotted head screws" are supposed to have a D-ring
that connects into holes on the sides of the head. That's the way mine
is. I just lift the rings, twist them, then use them to pull up the cover.

If the D-rings weren't on mine, I'd think they were just big
slotted-head bolts.

Bill,

Too late for you, but maybe not for someone else: Many years ago I added a
lift strap made of about 18" of seat belt material. Doubled over, with the
loose ends doubled together again and secured to the hatch with a flat metal
plate and 2 screws, it makes a loop to grab & lift. Since it lays flat, it
can be hidden under the lift-up carpet edge (which also covers the latches).

JWID,

Ken H.

Those bolts have a groove in them. Originally they had an aluminum
washer the fit into the groove so that you could lift up the cover by
pulling up on The rings in the bolts. Often the washers break off and
the bolts then pull right out.

A fix is to remove the plate so that you can get to the bottom of it.
Then use a split 1/4" lockwasher. Open the lockwasher so that you can
slip it over the bolt into the groove. Close and flatten it with some
vise grips and it will stay in place. Screw the plate back down and
the bolts will now function as lifts after they are unscrewed.

You want to screw down the cover instead of just letting it's weight
hold it in place because that compresses the gasket and reduces the
engine noise a lot. It also keeps air fron entering around the seal.

Speaking of engine covers...all I need is one more project: My cover rubs on
the engine, even after I cut out a piece to clear the HEI distributor. I
remember reading about the front of the body on the early models not being quite
as sturdy as it could be - any chance the body is drooping with age? I can
certainly identify with that! I'm thinking about going to an insulated metal
plate so it will be thin enough to clear the air cleaner. I like the nylon
strap idea - any metal latch tends to get hot.

Gary,
Yes, the rubber donuts under the tube body mounts at the front could be down so far as the allow the rub.
Also, I have seen the relief cut out for the air cleaner reversed from the factory.

Bill,
We stockn the ones with a pull ring on the screw,
It is expensive but we supply a lot . The manufacture did not want to tool
up to male them unlees we were going to pay the high price. We did and we
have them.

My PO routed out a circle to match the air cleaner and added flame proof insulation . Then he put heavy gauge metal on top of the cover where he had routed out the wood. ( He did not go all the way through the wood with the router).

Are you sure that was the PO? That is exactly what GM did.

My cover has the same stock cut out for the cleaner.
Can it also be time for body pads as well as donuts?

My '73 Glacier has the routed recess reversed. Or, were the ninges and hold
downs reversed? Just as Dennis mentioned.

I just assumed it was the PO, but then the PO that I bought the coach from did not do anything, including changing the oil and filter for my trip home from Charlotte. I did that at my farm in SW Ohio where I stayed for two days. In fact, it was so dirty that I changed the oil and filter twice.

That's there for EMI reduction.
