guh, The electrode of the number 2 cylinder BROKE off. Its completely gone. I looked inside the chamber, I see dents, im not sure if its dents, or bits of carbon cleaned off.

I checked the other cylinders, they are fine.

I had\have a mis firing. and on the way home last night, I herd a bad noise, and can feel loss of power. I knew it was bad, and I limped it home.

What could have caused this?

 

are they iridium plugs? were they over tq'd?

 

I dont think they where over torqued. This happend maybe 3 months after droping the motor in. they are NGK's R's. I dont think they are iridium.

 

anyone?

 

before bed bump,

guh so depressed.

 

most stuff that falls into a cylinder chamber will screw it up pretty good, iw ould tear head off and check it out and possible pull that piston out cuze lil schrads could be between block and piston rings and scratch it up making you loose compression, do compression check or tear head off my 2 cents godd luck with it

 

Ya, thats what Im thinking of having to do, but I dont have the money, to pull the head, I suppose I can do a compression check. but I dont think shards happend, It might have just embeded its self into the piston, or\and blown out of the exaust port.

Either way, the damage is done. If I DO pull the head apart, and pull the piston, Im going to build the motor.

I put new plugs, and wires (broke the old ones in my late night madness), I blew out all the cylinders, and a dust of metal flew out of the one with the broken electrode.

so if it blows, Ill build the motor then, but for now, Im going to have to drive it as is.


Im kinda stuck between a rock and a hard place. while im trying to build my 240, my Daily driver(crx) is having its own issues.

I mean, what else could possibly go wrong? right? If it burns a hole thru the piston, fine. rebuild motor, if it ***** the cylinder walls, new b16\18\20 block. If it fuckes the head. Bare b head.

If it completely grenades, I can salvage the parts. and just get a b16\18 short block.

 

Sounds Like the same exact problem my lil brother had happen to his CRX B16. Too bad its not a kick *** 94 GSR. I would have to say the days are numbered on that engine, so shopping around for a new long block would be a good idea. If the motor lasts up until my Winter break from school I say we should rebuild it ourselves, or maybe buy a rebuilt engine and return yours as a core.

New Piston $50-75
New Rings $20-40
Headgasket, timing belt, water pump, head studs $200-250.

NGK R's SUCK!!!!!!!!!!!

Peice of crap Casting method produces a weak joint at the bend. Thats why Bosch welds the Grounding electrode to the plug "Think Smarter not Harder - NGK"

 

Wow I didn't know NGK's sucked so bad. I wonder why they are the factory plug for my MKIV Turbo Supra and my 2001 Prelude? Come to think of it I think almost all Japanese car manufatures that I have seen use them a Factory plugs. I guess you know better than most automotive engineers.

Its new pistonS, Im not going to replace just one. And I dont know if I should rebuild to stock with Honda parts, or rebuild to awesomeness. Also, The cylinder walls might have to be Rehoned\overbored\resleved. who knows, and im NOT going to do that in the front yard, NO THX.

Maybe we should Rebuild it to CTR, or ITR specs.

After getting the short block redone or getting a new short block, I think im going to get it balanced and harmonized. where they take a little metal off of the Counterweights to balance it out.

the head is probly damaged as well. being an interferance motor and all.

but a b18\GSR\ITR block, with B16 head. would be nice

Meh who knows, but it doesnt make sense as to why the electrode fell\broke off. for one thing, there was NO DAMAGE to the the end of the spark plug, Im not running turbo, nitrious, its a STOCK b16. It never smoked, It never had any issues untill this.


and, this has happend before to my dad. but that was a long time ago. What im saying, is that I dont think its impossible. but it COULD have just broke\fell off from the normal use, for what ever reason. Im not pointing fingers. and thats my brother your talking to.

i LIKE NGK's.

 

Well First off, I AM a Mechanical Engineer with Numerous Awards in Engineering, I worked at a Tool and Die Manufacturing firm and learned alot about Metallurgy and how some parts MUST be manufactured in order to withstand high temperatures and constant climate changes. I designed a "CSRV" rotary valve motor http://www.coatesengine.com when I was 21 on AutoCadd but never had the financial backing to go any further than the drawing board. 3 years later the Design was built and is now one of the highest reving motors with an increased efficiency twice above a conventional poppet valve motor. NGK is used by Japanese Corps because of the extreme cheap cost of production and relative reliability. In fact most companies are based on those principals. I am now a Financial Analyst because engineering cant take you to the very top of the corporate Ladder. Go learn some thing about Casting, Extrusion, and Relative Reliability. And also Take another look at the Bosch Plug and the NGK plug. Go ahead and try and bend the Bosch Electrode compared to the NGK. You will notice a softness in the NGK and total stiffness in Bosch. Now I rest my Case.

Oh boy, Agian with the Coates engine ****!!!!! I will admit the NGK plugs ARE cheap, but even the best, most expensive parts, can fail, because of a desighn mishap at the factory. You see it happen with clutchs alot, its just one of them freak accident things.

engineer or not, NGK is a better plug than bosch. i would never put a POS bosch plug in my car, they might be manufactured better but they ******* suck as far as performance/lifespan goes but i guess all the people with modified cars that are running NGK's making huge power without an issue dont know what they are doing becuase bosch is the better choice. +4's FTW!

LOLOLOLOLOLOL

 

Thats Strange reasoning. Just because people are using the plugs and making HUGE HP gains has nothing to do with the plug brand but simply the gap and temp of the plug. There is no Clear cut advantage of any plug except its quality of life. Everything else is specification to what a particular engine needs.

I had Bosch +4 in my Camaro and in my Integra and they worked FLUCKIN great. The NGK Platinum's "worked".

Oh and one more thing NONE of the Ground prongs broke off either. But I did hear a NGK R Ground Electrode Broke Off inside a perfectly great running engine, destroyed the engine and now NGK spark plugs will never be purchased again until further NGK innovation. NGK=Garbage

 

ALTHOUGH!!!! If it is later determined that some how the piston actually HIT the sparkplug I will "EAT ALL MY WORDS" and no further condemnation of NGK will continue.
