I was over at a mates place this week and we were just having a look around his shed.....(where my motor is being stored atm)....and his son has had some mates around so they have taken the cover off...and wasps have built some pretty little mud castles in the intake ports.....(motor has no manifolds on it)

What can i do...

Head off job? or....

(deep sigh)

Turnthe engine on its side on an engine stand, one cylinder at a time turn engine until cylinder is in compression stroke (vavles closed) break away nests, air blower, hope for the best.

One of those fibre optic cameras would handy be handy aswel

Leave wasps alone. They get very narky when you disturb their nest or spray insect spray in their general direction - particularly European wasps. Unlike bees, they can sting multiple times (they don't lose their stinger).

If they have gone up the exhaust they may have nested inside the cylinder, the one with the valve open. I worked on a pump motor from a farm with wasps nesting like this and it wasn't worth rebuilding. The clay gets into everything, little buggers.

Definitely need to pull the head off.

Ok i went to the head shop today (super flow heads), I was told if i can give it to him with no cams in it. Then to have it acid dipped, new seals, and machined, would cost me between 300-400 dollars.

Does this seem about right?

So this leads me to this, would i have much problems pulling out the cams, and then re installing them again (or maybe aftermarket 256's or something...).

I can get a genuine nissan vrs kit, for approx. $380, so i would provide the seals, (this should bring the cost down a tad).

And would i really need to machining?

I have no idea tbh when it comes to doing any work on the heads this will be the first time i've taken one off and put it back on myself so yeah...dun wanna mess it up..

Cheers

Price sounds good.

And the valve stem seals are worth nothing really, so won't be a huge saving there.

I payed $550 for mine with a crack and pressure test.

The machine they normally do is just a tidy up (skim the surface and enough to make sure valves seal properly)

May as well keep it all in this thread, down the track the motor will probably have between 15-18psi getting pushed around it, would you guys reccomend using a metal head gasket? I had a quick look around the site, and from what i can tell the cometic head gaskets and the such wont sell properly unless i have both surfaces perfectly true...would this be the case if i wanted to run any sort of metal gasket, so machining would be in order for both the head and block?

      R33 GTR running -9 with no tune

      By 677_GTR · Posted

      Hi guys, I’m new to the GTR scene. Picked up an R33 GTR earlier this year that needs a lot of love. I’ve been going through the hot side, changing all the gaskets and while it was all off I managed to score a set of -9s. It still had the stock ceramics so I was pretty happy to get the 2860s.  I live in a small country in the pacific with 0 performance car scene. No dyno’s no performance parts, let alone stock parts for a skyline. I order everything from Australia and do it myself. This means I’ll be running the stock ECU. Maybe down the track I’ll get an aftermarket set up and do a remote tune.  Will the car run -9s on stock tune safely?  I have a very heavy foot so I really hope so 😂   thanks guys

      Leaking Rear Subframe Bushing?

      perfect, no rush to address the leaking bush then, it's not doing much/anything

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By GTSBoy · Posted

      I'm not sure if it will bolt up, but.... I'm reasonably sure that the ID of the runners is somewhat smaller on the NAs. So it probably wouldn't be a good match at the flange where the top and bottom meet. So that would be a reason to not do it. And the skinny runners would be the bit you're keeping, which would be a reason to no do it. You'd want the big runners if you were doing any work to swap stuff. Why not just use what you've got, like nearly everyone else who has +T'd an NA? You don't need or want the TCS throttle or other stuff that is specifically DET inlet/crossover.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Makes sense. For actuators, if the pressure itself isn't adjustable, that would mean I'd need to think about 2 different actuators with 2 different pressures on paper in order for them to work at the same time if the turbos behave differently. So measure the difference in psi needed to move both, and then get an actuator to match that difference. Assuming I cant get rid of it by adjusting the arms.  You're exactly right, never happens in gear 1 or 2. I can occasionally get it in gear 3 if going uphill but its very small. Only ever in 4 and 5. Seems kind of backwards that one of the points of VCAM is faster spool but if it introduces shuffle then it actually slows spool down.
