As per your first post. That's not new info.

Also it's a weird thing to say. I think you mean to say the bottom end is rebuilt? It's not a new block is it?

 

Plugs foul by either runing rich,  burning oil or less likely too cold heat range.

Also to add to that your breather setup is wrong and atmo blow off valve with maf sensor is not good. Both will  draw in umeterd air at idle but that makes it run lean, so not really related to the fouling problem.

 

What injectors are you using? Did you happen to change them or other stuff when the new engine went in?

Yes, hence why I suggested that the rings were not bedded in properly. There is a procedure to make a new engine work properly. If you do not follow it, you will glaze the bores and you can forget about it every being any good after that.

Thanks Ben for the responds

Umm can you walk me through the proper step for the breather and the bov  

What do I need

I'm using the standard ones purple blueish ones

I changed new cosmetic headmaster and arp  studs also all new valve seals

 

No mate, I'm not going to type out info that is all over the place, but I will say your options are either factory style breather system (with oil seperotir if you like) or completely open to atmosphere. It can't be open on rocker and still be connected to pcv.

 

Bcpr6es for plugs. What are you using?

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
