Built my engine : strange

[menfou]

Hello,

After 30000miles with 525whp on stock engine, I ordered some parts from SOS.

Yesterday I removed my engine from my NSX, and today I found this :
Mud, shit

And I think consequently :

molten resin

Mud, shit on the TB

Oil sludge due to heat break down? What type of oil where you running and how often did you change it?

 

[menfou]

I use Mobil1 5w40 or Motul 300V 15w50.
I change my oil and filter every 3000-5000miles.
I bought my car 2years ago with 53000miles; now she has 84000miles

..yuk, that must suck. Keep us posted on what the result is. Hopefully nothing too bad requiring a rebuild.

 

[menfou]

I will check the pipe between turbo and TB tomorrow to see if I have oil.
Do you have a idea for the molten resin ?

I rebuit my engine because I though my rings are bad, on my oil catch can, I had a lot a oil and pressure.
Bu tI check cylinder pressure, and I had 13.5bar on all cylinder.

Melted resin is normal I believe. If thats the cam sensor then mine is doing that and larryb said it's normal.

On my crank I can see ..| ..| ..| ....| for the main journal bore

On my block and on each main cap I see 2 2 2 2, but I don't see 2 on the nsx manual, only A or | , B or .| , C or ..|, D or ...|
2=B ??

I think I need Yellow green, Yellow green,Yellow green , green brown

Perfectly normal for a C32 engine. Never seen a Legend that doesn't have the resin melt from the crank angle sensor and they're generally messier than that. I'm told you can buy that material and repack it if you're so inclined.

Normal? Wow. By normal "do you mean not great but not catastrophic for the engine but just the way it is," or, "it happesn, deal with it, some damage may occur.."?

 

[stevieray122854]

Normal as in "It's typical, don't worry about it and nothing bad is going to happen." A crank angle sensor might fail but that won't be the cause. If melting resin was a contributing factor to failure, don't you think Honda would have changed the design during the 15-odd years of manufacture? They're not GM where defective design is the norm.

Quit worrying about it. The C32 series is a very durable engine.

After 300miles with my rebuild engine, I noticed a strange noise.
I am the winner for the IDIOT 2009 :biggrin:, I forgot to bush the stock rods.

I need to bush the stock rods, and change my head gasket again.
My engine is open after 8hours, good time :biggrin:

I have a oil catch can, and I don't understand why my pistons are so calamine
The n°2 piston has a strange color :

well it takes a man to admit a mistake like that(and perhaps costly) but raises the question how many engines you built(no disrespect intended). What worries me is the amount of deposits already on the pistons. I mean its not discoloration or a mere slight carbon film...it looks like a lot!! and on that low of mileage= WTF?

good luck
