How did you remove the expansion plugs and where did you find replacements?

I just use a flat tip screwdriver, place the tip to one side near the edge and tap on it a few times till it turns sideways, then pry it out with the screwdriver or pull it out with pliers. Red River Parts & Equipment in Tx. has them in stock, you will need 4 to do the whole motor, the one in the head is smaller, they are $3.95 ea. part# 8754412 You need to call or order by e-mail, 903-547-2226, info@redriverparts.com

Thanks again Dan, the plugs came right out but I wasn't expecting all the "rust bunnies" to come with it.My block needs a thorough cleaning of the water jacket and I'm not sure that soaking in the degreaser will get'r done?!

Hi, Disassembled the OLD "new old stock" head I've had for about 4 years and it was not what I expected,
Image

Image

Just found out that my valve spring compressor is still in Baltimore :x so I took the valves out the old way. :roll:
Image

Image

Image

you stuff some rags under the valves to keep them from moving, hold a deep socket on top the spring and hit it with a SeaBee tool. :lol:
Image

Image

Image

Image

Image

Image

Image

Image

cleaned up all parts and the valve seats and guides look good, I'll take it to work tomorrow and blast the head, then I'll hand lap the valves seats.

hg, you can flush it out by sticking a water hose in the holes or, use a high pressure washer. The only other way is to have it hot tanked. Happy to help! :) 8)

That is some good work there Dan :)

BTW... if you want to do this up cosmetically too you can get an NOS Engine Data Plate from Surplus City Jeep Parts. I got NOS rivets from Saturn. Then Steve K. at Owens Export is doing the stamping for me.

I'm not crazy about how the rebuild tags look, when they're fixed to the original data plate, so I had Steve (Owens Export) stamp the NOS engine data plate with "Rebuilt 5-10" as well as "Bore +.020 Mains -.010 Rods -.010"

Keep the pictures comin'!

Hi, here's a little update on my Motor, I got a new water pump from Red River Parts and put it on, I had to file off some metal from one of the mounting bolt Boss, it was too thick and would hit the thermostat houseing.
Image
Image

I then bolted on a tranny an mounted the radiator, now I could put it in the mutt and have a solid platform for a longer break in run.
Image

I made a upper hose from one I had on hand, this is a good number to keep incase you ever need one out on the road, I cut off the 2 ends and it fit like a glove! :)
Image
Image
Image
Image
Image

I hooked everything up that I needed to run the motor, 1 rubber line to a 2gl gas can on the floor, ( I used a 66 Ply fuel pump) 1 ground wire to the mutt frame from 2 batt's on the floor, 1 hot wire to the distributor. hit the starter with a hot wire and fire it up. :)
Now! this is where the finless brown trout hit the fan! :o I had it at an idle and all is good, I run it up to half throttle and :shock: POP! oil went everywhere, :( The oil filter split wide open. :? I looked at the oil pressure guage and it was at 75psi and going down as I pulled the wire off the distributor. :cry:
Image
Image
Image

My first thought was, the cam bearning oil holes may not be lined up properly, :?: (trying to put the blame on someone else) then the more I thought about it I remembered something about the oil pump! I had taken it apart and "cleaned" it BUT, :oops: I didn't remove the pressure relief valve from the gear cover and clean it. :oops: :evil: :roll: so now I need to pull the oil pan back off and properly reclean the oil pump. I have a new oil pan gasket kit on the way. To be continued! :roll: :lol:
