Yes, so would india ink. You want something that will stand up to the lapping compound.

 

[aznpersuasion]

Hmmm...I doubt any of that exists here in Yuma. Anyway I just tried to stick the lapping tool on the valves and it wont stick. I assume because they have a lot of build up on the faces. Any shade tree way to clean them? I have some wire brushes, but they arent soft.

Gonna soak one in chemtool carb cleaner for a bit and lightly take one of my wire brushes to it.

this took about 1 minute. so either i did a bad job or this valve wasnt that bad

 

[amtronic1]

From the picture it looks good.

 

[aznpersuasion]

ya, the exhaust ones were much more...not good. did the best i could and so far all pass the water test. installed new oil seals and put them back together.

 

[lesterl]

your rocker arm nuts on the right way? could just be that it is 2am here....

 

[aznpersuasion]

They arent fully seated, thats all.

on a side note. when i get my ecu from blackbear i know that there is a relearn procedure that needs to be done. in my searches it looks as though that a relearn may not require a scan tool? for the passlock systems (i think i have this) you can just either try to start the vehicle and see if a security light appears. if none appears your good to go. if one appears the vehicle may stall with a security light present. leave the ignition on until the light disappears and then your good? i opted not to send in my stock ECU in case i need a scan tool relearn the hard way and i can still get around.

 

[aznpersuasion]

both heads done

last piece to the puzzle

 

[aznpersuasion]

#1 main - .0015"
#2 main - a tad under .0015"
#3 main - same
#4 main - .0015"
#5 main - tad under .002"

.004" crank shaft end play

so im torquing the rod caps and the manual says 20 ft lbs plus 55 degrees. thats seems like quite a bit. and since i dont have a degree wheel does anyone know if i can just go to another ft lb measurement?

EDIT: never mind i figured it out. bottom end is now together. Takes about 20 ft lbs to rotate bottom end. good? bad?

 

[amtronic1]

25 is probably in the range, depending on if the cylinder walls are lubed, etc.

 

[aznpersuasion]

i lubed with 30 weight oil. not sure if that will add any significant amount of resistance

 

[lesterl]

Dont think lubing the cyl walls will have anything to do with torquing rod caps.

You can by a torque angle guage (1/2") at Autozone for $10.....

it didnt, just a note towards force required to rotate crankshaft and rods

 

[aznpersuasion]

makin slow progress. going to have to get a puller for the darn crankshaft timing sprocket.

Blackbear Ecu arrived today

 

[lesterl]

Cant wait to see it back together and hear how it runs.....

 

[aznpersuasion]
