It would be wise to replace the intake gasket with a new one than to try to fix the old one. How long it would take to replace the gasket would depend on the model, year and engine type you have.
It took me about 3 hours. Pro can do it, I guess, for about an hour.
It should take about 8 hours give or take...
take off the head, replace gasket. reinstall head
4 hours.
Depends entirely on the year and fuel system. You did not provide that info.
If you know what you are doing and are comfortable swinging wrenches, it shouldn't take you more than 3 - 4 hours. If you are not comfortable doing this, take it to a competent mechanic.
simply remove the valve cover gasket,take the old one off,clean the area well, and replace the gasket,tighten the cover evenly.(if ur gasket is made of corque take care not to break the gasket
Take it off, replace the gasket
about 10 hours alldata says. but if your good it can take about 6
you should only change the gasket if you have to take the valve cover off....... you should only change the gasket if you have to take the valve cover off.......
I would be more worried about the length of time that a head gasket has been left on your Jimmy. I take the gasket off my Jimmy right after I'm done using it. 16 years is a long time.
