I wish someone would design a nice rubber gasket to seal off water from the engine area for us guys that don't want an engine lid. Just need to seal off the hatch glass. I think that would sell.
You bought a 16 year old car with high mileage (for an NSX) for a daily use vehicle and didn't expect anything to go wrong?
BTW, My car has NEVER had an oil pan gasket leak...

Your lucky. My 53,000 miler oil pan leaked. I strongly recommend changing this before any header install.You bought a 16 year old car with high mileage (for an NSX) for a daily use vehicle and didn't expect anything to go wrong?

+1 for Ray Laks Acura. I usually order from Tim but JR has been helpful too. Great guys and the best prices i've found.

lol big_D. :biggrin:
I know there is an optimist in you!
the oil pan gasket should be fixed since it will leak on to your exhaust pipes and you'll be smelling burnt oil. I recommend you getting that changed at the same time you do your header install since exhaust pipe removal makes the oil pan job much easier.
happy motoring
Rob:smile:
I appreciate the info davidf and Ron98, I had my headers installed last year and have never had a problem. My tech didn't even mention that I should replace it. I guess time will tell.
To the OP, I am sure once you get these minor nuisances corrected, you will be enjoying the car much more.

no leak, no problems :smile: im sure your tech would have told you if there was something going on.
drive on brotha :biggrin:
Why didn't you get a CEL when one coil pack isn't working? Maybe the malfunction isn't bad enough so it is not detectable by the ECU?
About that "wobbling engine at 1900 rpm which is completely normal", I've heard it can be due to worn engine mounts, or not torquing the engine mounts in the right sequence when reinstalling engine into the car. Anyone else have more ideas?

The RWG is not designed properly and as such allows water in regardless of the engine cover seals.
I approache DF with and idea to solve this but they are still considering.
I think a few would be sold but, we'll see, I might just have to have some made locally.

Stevetwors,
Welcome to Prime and I understand your frustration because I'm living it.
My NSX is a mint condition 1991 but that being said I do have 2 major issues on the car that cause me to lose my hair! One is an electrical gremlin that the previous owner and I are both experiencing and not yet able to diagnose and the second is an air conditioning system that sucks if best! Both bug the living crap out of me and are now my major tasks to fix as I've finished modifying my car.
Sometimes these things get the best of us but you need to put it behind you(I was swearing like a trooper one evening after just having enough and wanted to sell her, kick in the doors, etc.).
Sounds as though your on the right track...

I was under the impression it has to do with the basic engine layout/design (90-degree V6). It can be made worse by various things (engine actually missing, engine mount issues, etc) but the basic vibration every NSX has at certain RPMs is not because of worn or mis-installed engine mounts. It is, as your first line notes "completely normal."
nsx has inherently rigid engine/differential assembly. if those two were mounted separately as in most cars, better damping of the vibration could be afforded as it would not affect the rigidity of the drivetrain. worn engine mounts will make the problem worse.
First, the air conditining in these cars is to say the least the dogs bollicks! (R-12) The only thing i've been in that cools colder and with more force is a
Bell 212 with a Parker Hannifin A/C system. They both virtually throw ice cubes at you only usually in the 212 you have a helmet on. In the NSX you have to duck.
I've heard of a few that have evaporators go bad and they are a huge pain in the butt to change but if you take care with scheduled cleaning and use it should last the life of the car.
Next, I bought an engine dampner from Henry at GTOne and it was a little pricey but it virtually stopped the engine vibration and took the load off the engine mounts while allowing it to move under high torque loads. Highly recomend them for what it's worth.

that damper is mounted in 'almost opposite' direction from what it needs to be to really work. more bling than function.
Steve, I logged on tonight the first time in several months and saw this and you are in Tampabay.
I logged on to handle some awful business of my own not related to the X but since I am here I will deal with you first.
welcome! I am always pleased to meet another NSX owner unless they are a stuck up dick. I also try to be helpful as possible in resolving a hairpuller.
I have several good coils that fit your car if you are still unresolved!I always checked my own coil packs and injectors with a digitil meter.
I have a defib-pacemaker that is defective to begin with and if they had told me I would (and have on half a dozen times) get zapped working on the electronics in automobiles I would not have let them install it. its never saved my life I dont think and damn near killed me a couple times.
so if you need or want to talk pm me ya digits.
Also we have an outstanding local NSX mechanic named MIKE PERCY! He works for crown in clearwater and he is the straight up shit. that boy has been working on the NSX since it came out and was one of the first to get certed on the car BTW he owns one too! so trust me when I tell you he knows his shit, is honest and a great guy even if he thinks I am crazy (in a good way) and hope to see the bastard soon its been to long. HE DOES NOT WORK FOR FREE! just a heads up. thats how he keeps the lights on if you know what I mean
Well good luck and like I said if you need some info or help let me know. I know a tad about the X also. I treat everyone the same new or old to sporting cars and will never yank your crank, I will always tell you what I think about the issue as in the truth not candy coated
again a warm welcome
best regards david
ps I am not in the best health so I will get with you if need be on my time and when I am up to it.and if you are squared away maybe a run sometime soon

thanks man! yup got the problem resolved. runs very nice and stout now. 2 coils were bad. i still think theres room for improvement though, i wonder if replacing all the coils with new ones will make the motor run even more like new?
i want to meet with nsx drivers!

Have you replaced all the spark plugs too?
Why replace just 2 coil packs - go ahead and replace the others all at once along w/ the spark plugs.
Also be sure your injectors are clean. Send them off to RCengineering and they will clean and balance them.

i put in some spark plugs (i think bkr6es) and after replacing the bad coil packs, it ran even worse, backfiring and just really horrible performance (probably because i didn't gap them, but it said they are pregapped to the same factory spec gap listed for the nsx, so i just put them in). then i put in the oem plugs and it finally ran good again.
you and me are on the same page buddy, i was thinking the same thing, might as well replace all the coils. i figure what affects the engine running smoothly the most is the quality of the spark and quality of the fuel injection spray. another thing i noticed is there is a sort of spring load tension inside the coil's "arm" which keeps constant pressure against the spark plug to create a constant connection. the new coils have a noticeable spring tension pushing against the spark plug whereas the old coils have almost no tension anymore, and, now that i think about it, they dont even feel like they are touching the spark plug at all when i tighten the bolts. but if nothing else it would be good if all coils have equal strength to the spark they generate, i think little details like this make a noticeable difference in this car.
and i was thinking the same thing about the injectors, but i was thinking of just putting new ones in, not cleaning / flow balancing them. if i am going to the trouble of removing the rail i might as well spend a bit more to just get new ones.
No need to get new injectors. Just send them in to get flow balanced/checked.
