Removing Head From Rb26 - Scar Non?

[Angus Smart]

I did a quick search but found nothing..

so my question is.

when removing the head from a rb26 in a R32 gtr.

what is holding the head down on the intake side? i have removed turbos and everything on the hot side.

i'd say something under the plenum as i have not removed much from there other than fuel lines.

i've removed all the head studs, the 3 bolts in the corners of the head and the bolt on the ac pump. i can jiggle it a bit but it wont lift.

cheers

P.s. i've gotten bored waiting for the new motor to turn up so i decided to pull this one apart as much as i can to hopefully learn a few things!

And to add to this,

do i need to remove the intake chamber, throttles, etc?

or can it be pulled off with intake and throttles attached

cheers

whole heap of vacum lines

And a bracket if i remember correctly

i found a manual and i will dig into that tomorrow,

so it can be done without removing the plenum throttles etc??

just found a photo of new enging which looks pretty cleara, all these suckers come off??

it surely feels more solid than just hoses tho.

no body can tell me what needs to be removed or loosened on the inlet side to get the head off with throttles/plenum still attached??

this is on an RB30ET but from memory dude there IS a bracket that is anodised gold that goes from the block the the runners, i guess all that alloy would need supporting, having said that your plenum it completely different, sorry disregard my waffling!

Done just as it started raining,

may have damaged the head gasket on the way out and i cut a hose or two as i had to act quick. damn rain. inbetween 6/5 on the headgasket looks a bit bent but this may have happened when getting the head off as i was jiggeling alot trying to find the last two hoses.

if you dont know, i had 0 compression in 6. all the rest were fine. 150ish across the park.

blowing alot of smoke/oil

inspecting under the head all the valves appear to be perfect, the top of the piston appears to be fine also. the bore also looks good in 6.

i will get some photos if the rain eases.

[Angus Smart]

heres some photos i was able to snap between getting wet.

as you can see, cyl 6 has a bit of a mark well gouge or whatever but the rest are fine.

And another shot of #6

doesn't look too healthy...

which makes me feel a little better, as i was thinking it was only a head gasket..... and i've just bought a new motor! haha

[SDEWY5]

been knocking baaad, had same thing wit mine, piston looked identical but on a RB25

[Kaido_RR]

lol scar non! lol

[R338OY]

Yeh i agree. Looks like it's taken a bit of a lashing.

[DRIFTER]

do you want to sell the head?

[tacker]

yer you seem to have had some det which will have a broken ring land when you get the piston out at a guess.

Have a look at the other pistons when you get them, take note of how the pistons look where the ring touches the ring land see if there is any marks that look like erosion.

[Angus Smart]

Wouldnt mind some head. haha

but at the moment, no not looking at selling it i may rebuild the motor so going to keep as much as i can for now..
