Investigating a manifold leak on my 85 FJ60 and found the metal elbow of the front left insulator laying on the smog pump bracket. It appears that the heat resistant fabric/insulation it was attached to rotted out. There were a few fragments of the material still attached to the manifold.
Anybody here care to enlighten me regarding the true purpose and actual functionality of these insulators (there are front and rear ones) on a 2F? Is it considered a "must replace" item? I saw them available on SOR's online catalog, but would like to "rebuild" the ones I have if possible with new insulating material...any thoughts?
Last question... can any of you highly experienced mechanics (or anyone who has ever replaced their manifold gasket on a 2F) give me a very general rundown on sequence of events. I have the necessary tools and factory manuals, along with a well lit, and dry garage to work on truck. Rough guess of how long to accomplish, and where are the trouble areas to be aware of? ???
Thanks all!
Cheers, and keep on Cruising!
