    Update!

    Broke some valvecover bolts while trying to tighten them down to make a better seal. Fail.

    This was a great time to replace the bolts and give the valvecover a new look.

    Starting to clean it up:



    Yuck!



    Painted (same color as my old GA16):



    Ditched the recirc. hose and added a breather-baby-filter (will remove the redundant hose soon):



    Replaced all the bolts:



    Quick fix for rusty hood sand-spray, (don't want it to rust away until it's gonna get painted properly):



    Thanks for today!

      Nice! I don't remember the last was when I saw an NX.

                Got tired of the ripped old seats, and started thinking about replacements


                Scored some almost new bucket seats!


                Started fabbing up some rails from the N14 donor seats


                Stay tuned, I'm about to start welding later this week

                  Nice work!

                  Engine looks very very nice and I think those seats will look great too.

                  I'm worried about the crankcase breather filter. Shouldn't that upset the ECU because you are venting unmetered amounts of air out from the engine?

                    Thanks!

                    Regarding the filter, quite the opposite! The crankcase ventilates AFTER the MAF, so it adds extra unmetered air at WOT. The main reason I'm ditching it is to make the intake cleaner, since some oil also travels trough that hose when the engine get's old and worn.

                    Here is an article on Crankcase ventilation from SR20-forum, It should also apply to your engine

                      Oh! I see it a bit differently: all the air inside the crankcase is metered air because it is drawn in AFTER the MAF. If you are taking in air to the crankcase from the atmosphere (or venting it out) instead of drawing it in via the MAF, the crankcase returns more (or less) air into the intake than the ECU knows. When you recirculate the crankcase air, all the air used by the engine will pass through the AFM and the ECU will then calculate the AFR correctly.

                      Correct me if I'm wrong. I'll have a look at the article as soon as I have time (I'm at work now so I can't sit around browsing car tech articles :P )

                      If you want to keep your intake boot clean, I would recommend fitting a catch can. Nothing personal about this; I do like how your engine looks with a breather filter. I actually use one myself (in addition to a catch can), but my engine is carburated so it has no metering problems.

                        I took a look at the article. It seems that the article agrees with me:

                        venting WOT section to atmosphere on 1991-1999 engines with "breather" filter:
                        (image was here)
                        Effect on the following characteristics:
                        De-clutters the engine bay - Maybe
                        Simplifies crank case ventilation system - Maybe
                        Helps remove more oil from the air - No change
                        Help evacuate the crank case - No
                        Maintains or improves the stock flow capacity - Yes
                        Helps promote ring seal and prevent blow-by - No
                        Helps prevent oil smoke in exhaust - No
                        Helps prevent dip stick from popping out - No
                        Helps prevent oil leaks due to pressure - No
                        Helps keep intake track clean including throttle body - Yes
                        Helps keep intake manifold/plenum clean - Yes
                        Maintains or reduces amount of pollutants - No
                        Maintains prevention of un-metered air from entering the intake - No <-- this was what I was worried about.
                        Consensus: BAD IDEA

                        But if the engine still runs well, nevermind about my worries. I'm not criticizing you for doing that mod, just worried whether or not it will do good to your engine.

                            I don't know much about the NX, is the engine a SR20? It sure looks like it to me...

                              There's no metered air in the VC/Crankcase. There's only some blow-by gases that create preassure.

                              I think it's routed back to the intake (stock) on the assumption that blow-by won't be significant enough to alter A/F ratios and it gives it another chance to be burned, thus reducing the engines harmful output.

                              The article should IMHO say that it's NO CHANGE instead of NO. (Yes some preassure from the flowing air inside the intake helps extract these gases and MAYBE help with ring seal abit)

                              Bottom line: the breather filter isn't the best idea, but it's better than an oily intake..

                              Read first post? Yes, It's SR20 powered

                                Agreed. The engine isn't an oil burner and having oil on the inside of the throttle body doesn't improve emissions.
