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!

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.

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!

mine will be off tonite :P

i'm onto removing that acc valve now or air chamber its called just under the plenum.

will see how this goes it shouldnt be too long before i got it out.

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.

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.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
