Hello again.
Im planning on driving down the coast with a friend for my long wknd next wknd. He asked me if everything was good to go and I said I will change the oil as it gets closer to the wknd. Ive been meaning to check out the screws on the plates in the VVIS. So I figured why not and just jumped right in. I posted on FB to see if I could get the torque values and someone linked me to the manual on Prime which, for some reason, didn't work for me before. I started taking it apart and it was much simpler than I expected. It fools me EVERY time - being that its an NSX. Whenever I work on it, its becomes so apparent that its "just a Honda engine". So easy to work on, I love it.
I started with the cover......excuse the orrid, fugly red spraypaint. I assure you, it wasn't my idea, lol.
Removed the fuel line....
Vacuum lines....
I didn't really follow any manuals so the removal process was a bit out of order. Here, I unbolted the manifold. You could go either way, I didn't think I would be removing the fuel rail but I ended up doing so, more on that later.
This cap, I didn't really need to remove either but Im glad I did cuz its a good idea to replace that gasket.
Make sure ALL connectors are disconnected, the fuel line from the filter is disconnected (forgive me, Ive been out of the field for ahile but I believe its called a banjo bolt). It seems heavy but Im only 120ish and was able to lift it out fairly easy. Two people wouldn't be a bad idea.
This little bastard here was the only thing hanging onto the manifold when I lifted it out (the hose to the right of my finger there). It was underneath so it was hidden.
You can get an idea of what all I disconnected/removed.
Last oil change, when I poured the used oil out, it was less than 5 qts and I don't seem to have any leaks so I wasn't sure what was going on. I don't have a cause for concern yet. When I saw THIS, I figured this might be the culprit but I haven't tried to figure out the routing of oil in this area too much. One of the gaskets between the manifold and the VVIS unit was kinda oily but again, the only thing I can think of right now is the PCV valve (which Im replacing). The bottom of that puddle was a lil sludgy so its been there awhile.
Puddle in the upper right hand corner.
Manifold before cleaning..
The puddle again...
Time to clean...
I removed the fuel rail just to make room to clean the manifold and to not contaminate them somehow with the cleaning solutions.
And finally all cleaned up...
And vacuumed up the loose debris and hosed down the area a bit and scrubbed/wiped and vacuumed/blew out the rest.
Now if only I had the time and a dolly to drop the engine so I could clean it.
I ordered new parts (gaskets, etc.) from OEMAcuraParts.com so just waiting on those so I can put it all back together. Hopefully cleaning out all that buildup in the runners and in the ports will help it breathe a tad bit better. Anxious to see/feel the results. HOPEFULLY the parts will be here by Tuesday or else my trip might be fucked. Lol. *fingers crossed*. I emailed them to see if I'll get em in time. Their parts department is AWESOME. Great service! Very punctual with replies. Plus it doesn't hurt that they give a Prime Member discount.
OH! So about the screws - only one of the flaps had loose screws. I was scraping off caked on residue with my nail and the flap was a little wobbly. I was dumb and didn't think to wiggle them until then. I just looked to see if the screws were still staked, which they were. So make sure you verify with touch, not just by sight. Thanks for reading.
