Forget doing it by hand, I tried that first with my special tool and a hammer.

they all look pretty good, so perhaps i'll leave them in. i just didn't want them to be ruined during the cleaning process... this is all uncharted territory for me.

photohost wasn't working worth a crap for me last night, so here's what i accomplished yesterday:

started in on the block, drained what little oil was left, then dumped it

some nasty stuff came out so i let it drain like that for quite awhile.

while flipping the block around, i noticed some SERIOUS buildup outside the sleeves, hard to see in the picture, but it looks pretty dayum bad to me:

looks like orange calcium deposits almost.

next, moved on to removing the oil pan whilst the nasty antifreeze/oil mixture was draining out.


dammit dropped one. there's a ton of bolts on the oil pan

lots of sludge and some metallic looking material in there:


starting to get a clue as to what *might* be wrong...

need to get the crank exposed to get the pistons out, so these gotta come out!


with the pickup and baffle removed, i can see the crank and remove the rods/pistons. i inspect all of the rods for play and low and behold, we had a winner:

quiet a bit of movement there on rod #4. when i got pistons 1,2,3 out after reaming the cylinder ridges, they all looked to be in pretty good condition. got them bagged and tagged with their respective bearings.

now onto #4; when i got the rod cap off, this is what i found:

if you look closely, you can see that BOTH bearings are there (sort of) but in terrible shape.

they are paper thin:



^those are 2 different bearings there

[dom yo]

wow no good!! good thing you are rebuilding it though, im liking this thread, keep us updated yo!

[Jo060]

poor bearings!

That sludge looks so nasty!

So was the crank mangled on that journal also, I assume?

the crank doesn't look *too* bad, no major abrasions that appear out of the norm, but i haven't checked it thouroughly either.

my dumbass got the ridge reamer stuck together so i spent 2 hours trying to get it back apart, and by the time i got the pistons out and bagged up, it was dark and i was ready to call it a night.

as a precaution though, i've got a good crank on a line here in KC for cheap, just have to wait until friday when i get paid to pick it up

Maybe if you're fortunate it will just need a good micropolish or something instead of turning it. That would probably cost more than an LS crank is worth.

that's what i'm hoping for. but if this other crank doesn't get sold by friday, only paying $20 for it, so not a big loss.

going out to take the bag off the block, be back in awhile with some fresh picks of the crank, see what you all think

[IISaiNtII]

alright, definitely not a lack of pictures

hard to discern what's what to me though, the last pic is of the journal from rod #1, all the rest are the journal from rod #4











and the comparison shots:



it's definitely scored pretty bad. very very rough. probably a good idea to get the other crank now

after i got everything bagged, tagged, and tucked away, i went outside for a cigarette. . . found two large slugs on our front step that have been crawling around for a couple weeks. i hate slugs, so i salted the piss out of them

once again click for fullsize

+1 for the oversalted slugs, I used to do that all the time.

[IISaiNtII]

was going to give an update, but the photohost is being a pita right now...

maybe later i guess

[IISaiNtII]

alright, got 'em up finally after several tries....


first, got another crank that's in good condition:


will most likely have it balanced and micropolished

2nd:



golden eagle vacuum manifold. not really a neccessity but couldn't pass up on it.

and 3rd:

damn near immaculate turbo

[kommon_sense]

Is that a t3?
