Sometimes it takes an impactdriver. I will also use a large screwdriver with a square shaft and turn it with a wrench. The secret is keeping the screwdriver seated.

Try somekind of a penatrating lube. You can also try using heat like from a mini propane torch. You will be surprised how heat can actually help.

Use heat. I also use an old screwdriver that has a square shaft that I can put an 8mm wrench on. I also have filed the tip to perfectly match the cheesehead screws. I've removed 4 sets of tins that way.

just went through the same thing and it was a pain; I shot some PB on and let it soak; applied a little heat and they came off no problems.

As Joe said, make sure you keep the head of your driver seated flat; if it rocks around to much the screws come apart.

good luck

Impact screw driver works GREAT for removing stubborn tin screws. One tap of the hammer on the driver and the screw is turning out. From there it comes right out with a standard screw driver.

Let's see now. You have a 914 and you have a screw loose...


Seems redundant to me...

I found that the biggest screwdriver that Sears sells was the only thing that actually fit the engine tin screws. Using the correct-sized screwdriver helped a lot, as did spraying them with penetrating oil.

Access for a screwdriver that large is just about nonexistent for some of the screws, sad to say. I had the engine out when I was removing them.

Impact screw driver...the only way to go.
Use PB Blaster
