Valve Cover Gasket Replacement Help
Hello All,
New Ford Ranger owner here. My bf and I recently purchased a 1997 Ford Ranger 4.0l v6 ohv. We knew it needed a valve cover gasket on the drivers side and thought this would be a great weekend project for us. The truck we hope will be a work truck for him and a potential camper on the weekends. We got all tools, parts, and 2 repair guides. We go to do the job and now find it a little more complicated than we first thought. We call around to local shops and they want more than what we bought the truck for for the job! We go to YouTube to follow along to seeing someone else do the job. But all videos we found are of the sohc motor. Does anyone know of any step by step video walk through of replacing the valve cover gasket on the ohv 4.0l v6 engine?
Thank you in advance.

Welcome to the forum
Yes, quite a bit of parts removal is required to get down to the valve covers.
Take LOTS OF PICTURES!!!!!
Never know when you will need a reference for "now where did that wire(vacuum line) go???"
This is an article with pictures: http://www.therangerstation.com/how-...ntake-gaskets/
Basically you need to remove everything thats in the way, lol, I know, DUH,
Use CORK gaskets, not rubber
Rubber gaskets are for reuse, people that adjust valves often or need valve covers off for other reasons use rubber.
Great for reuse, doesn't seal well with stamped metal valve covers
Cork swells up as oil contacts it from the inside of the valve covers, so self seals over time, but after a year it can not be reused.
STRAIGHTEN the valve cover edges, where the gasket sits
People often over tighten valve covers, and what that does is bend the thin steel around the bolt making the areas between the bolt holes less tight.
So hammer edges flat so it will press down on the gasket all the way around.
And snug the bolts down, firm pressure don't bend the steel
Spreaders can help, but you would need longer bolts.
You just need 2 per side, for the lower edge
Oil can only leak from the bottom edge of valve covers, thats where the oil sits, lower rear area is where the most oil pools up.
So run some sealant on the lower edge of head and then put gasket on, then put more sealant on the top of the gasket on the lower edge thin coat is all you need
