splitting block

[funkytown]

i think im down to the last few bolts... specifically the few bolts in the water jackets. they are quite rusted and i slipped off a couple..

how do i get these out.. !!!!

[94 Leone]

Easy outs.

Drill a hole down the centre, and then the easy-out using a reverse thread method will pull the screw/bolt out as you turn it against the thread of the bolt and boom it's out- easy though turn in then out slowly- not just all at once you'd then be likely to snap it off in there.

[mattapo]

you can drill the threads out, put a pipe down there and a drill that fits inside the pipe it must be larger than the shaft of the bolt so it takes the head off

[94 Leone]

Or angle grind, even chisel and hammer (if you're feeling manly) to get the bolt head off, and then easy-out, because that'll preserve the thread. Though not everyone will have two sets of them though if you do ever get a chance to- they work brilliantly(when they don't snap)

Heres a set

really? ever seen where the said bolts are ! blah blah - Fail

[funkytown]

lol 94 leone wtf.. they are in side the water jacket.. i think ur just guessing.

out of interest what are those torqued to?

[rex-leggy]

get a spare socket that's smaller and hammer that barsted on least that's what i did .

for torque settings i found this (post #11)

If your meaning you have rounded the heads off, Use a 12mm 6 point socket on an extension and hammer it onto the bolt head, If this still spins, go to an 11mm 12point socket, and failing this your gonna need to drill the heads off.

They get done up to 35ft/lbs and the 8mm ones around the crankcase outter are 18ft/lbs

[DRFVDR]

If rounded them of YOU SHOULD OF BEEN MORE CAREFUL JON, i am disappoint, have i not taught you anything

as Scottspeed has said hammer a smaller socket on there,I use an impact socket (thicker wall) and an impact driver so as I hammer it on it tries to turn it at the same time

Impact driver looks like this

[funkytown]

lol come on demo have a little more faith than that ol chap!!! havent ruined them yet just trying to avoid getting into that position. also thanks scott and josh

[DRFVDR]

go buy an impact driver, they are very very good at that sort of thing,wont be overly much (depending on brand/quality) you will be amazed at how good they is

Oh you may need a decent hammer as well,a "club" hammer is what i use ( looks like a wee sledge)

[Stoffa]

I have the perfect size 12 point tube socket here if you want to borrow it jon, I too hammer the 2 problem bolts.

I paid an engine builder to remove a bolt that was too far gone though. cost me $50 but saved the block.

impact driver wont be much help on those bolts

[94 Leone]

Yeah sorry- wasn't reading whole thing just saw 'removal' sorry.

dose this apply to all ej20's?? cheers

[CUDDAS]

could possibly weld the center of a 17/18mm nut to head of bolt & try that,

maybe machining head of the bolt away & removing the rest once block is seperated -maybe what they did in stoffa's post

[funkytown]

have got it off, borrowed gregs attack tooly thing ;d attach socket, hit really hard and it spins for you anti or clockwise.

Smashed on 7/16s socket and got the offending 4 out ;D

closer to sending the new bits of the rick to work some magic

[scottspeed]

yes this is the torque for all the EJ20 engines. 35ft/lbs for the large main bolts, and 18ft/lbs for the perimeter bolts.

Also when assembling only very lightly nip 2 bolts up and with a good dead blow hammer give the crank a solid tap on both ends (lengthways) to get the thrust brgs to line up
