Crankshaft/block cryotreating

[kotu100]

sooo, had a spare 7mge i wanted to rip apart to see if the crank is still good.

pull the trans off, pull the head, flip it over and pull the oil pan.
i was wondering why the damn thing was still so heavy. the PO had a ghetto "trd" hood and no valve covers on, so water seeped down over time.

so ya think they got cryotreated? :biglaugh:





on a serious side note, whats the chances the crank is gonna be good?

I think you need to pull the crank to get an answer rick.

 

[kotu100]

yea im going to, i just found this amusing and i've never seen it before.
thought u guys might get a kick out of it.

 

[lewis15498]

Yeah thats pretty bad lol. BTW you were right about that block being painted. I'm thinkin I'm just gonna toss that motor in and see what happens.

 

[kotu100]

do eet, lemme know if u need parts, i got plenty. check out jens daily build thread if u wanna see wat im talkin about lol

but at least do the HG and some ARP headstuds



funny part is, when i was pulling the engine apart i was tryin to turn the clutch by hand to get the bolts out and i couldnt figure out why the damn thing wouldnt turn :biglaugh::biglaugh:

theres a good chance that crank is buggered. I pulled a crank from an engine with only ~1" of ice in the corner of the pan and that crank needs a 10/10 grind to be usable.

why did they have to get reground? out of round? or just rough?

well i took a rod end off to see what the rod journals looked like, the one i took off looks like the top one in that pic.
i didnt take the rest of them off because when i went to take the crank pulley off it spun, aaaand the dampener keyway is buggered,
oh well off to the machine shop white a diff crank.
