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?

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
