VCs = valve covers? You might try running some Marvel Mystery Oil. It worked to loosen up the lifters in my 57 Olds. Or maybe some SeaFoam. Also, have you tried to find thin walled sockets?well dan I am now up the creek without a paddle. The plugs that you show are far thinner than the AUtolights. I guess I will have to modify my 13/16. If I start grinding now I should be done by the weekend. : ()
I appreciate the suggestion on the plugs. After I pulled the VCs I saw lots of gunk. Do you have a suggestion as to what to add to the oil to clean the muck. Back in the day we put a QT of kerosene into the oil but the world of chemistry must have improved vastly in the last 50yrs.
I used the oil many times too.Marvel Mystery Oil.
And you’re certain it’s a cologne 2.8? Looking at some pictures, it doesn’t look like the plugs are that deep in a hole. I’d take a look at my heads, but they are at the bottom of a stack of parts, somewhere in my garage. Dan, how do yours look?
Early 2.8 use a plug that has a gasket later ones are taper seat. Both I believe are 14mm threads. Be sure to look at the seating area on the head. Flat sealing surface means gasketed plugs, Taper sealing means the later engines with taper seat plugsSuccess!!. I do not know for certain it is a 2.8L. Can only go by what seller told me. Distributor is in the rear. If the correct plugs were installed I could use a CRESCENT wrench to get plugs out BUT they are Autolite E6. What worked for me was soaking plugs in penetrating oil. Then took PLUMBER SOCKET which is made of such soft metal that if it is dropped they would flatten. (joke). Took me a few minutes to grind down to almost paper thin. I think the wrong plugs were put in finger tight with Loctite cause after one hard pull they came right out.
how right you r. Upon closer look the Autolites are flat seat HOWEVER they can't be correct cause of the issue of there only being space between tween head and plug to slip in a piece of paper. I guess I will check for NGK TR5 with no taper. While incorrect teh car ran fine on AUtolites.Autolite 65 are a gasket plug with no taper. The Ford Ranger came out in 1983 and the head used taper seat plugs The 2.8 in the Mustang ll used gasketed plugs 74-77. If the engine was indeed out of a Ranger then the taper seat plug would be correct. Use of the improper plug would cause a compression leak and the hot exhaust gas leakage could erode the plug sealing area
