Valve Adjustment

Post by ms1223 »

I've never adjusted my valves, so I ordered a set of EI rubber valve cover gaskets. I checked out SWPA write-up on valve adjustment. This may be a stupid question are the cylinders 1-2-3-4 front to rear? I see from the repair manual the firing order is 1-2-4-3. Any help would be welcomed.

Yes, the cylinders are 1-2-3-4 front to rear. The rubber valve cover gaskets are very nice and re-usable.

I did my valves adjustement yesterday and changed the valve cover gasket with the EI rubber ones.

Like Pcolette said very nice and reusable but I had the fourth valve cover blow the gasket out on resart ending with a bad oil leak on the exhaust, what a nice smoke show. :cry:

Don't know what went wrong. :?

I used silicon on the cover side and nothing on the engine side.

Took everything apart a second time and clean the valve cover and the gasket.

I put it back in using only a little grease on the cover to keep the gasket in place while I put the cover back in place.

Now it is OK, I rode the truck for around 3 hours in the afternoon with no leak. 8)

Any ideas of what happen :?:

Not sure who started using silicone on gaskets but what a mistake. A tacky product such as permatex aviation form-a-gasket on one side works much better. I know there are other products that is just the one I prefer. The rubber gaskets have got to be an improvement over the original but time will tell.

I used gasket shellac on my rubber gasket...didn't have the aviation stuff at the time. With the silicone..even if you let it set up real good, I think it will eventually blow out.

Cylinders are numbered 1 - 2 - 3 - 4

The firing order is 1 - 2 - 4 - 3 (I think)
