I'm not sure if this is a stupid question or not however I had to ask. From my personal experiences, on two occasions it was piston number 4 that broke a ring land. Does this have anything to do with the fact that this piston/cylinder is the closest to the throttle body? I was also running a skunk 2 manifold on both occasions....could that play a role in any way? Any insight would be appreciated.

eh, im pretty sure most anyone will tell you that #3 runs hotter than the rest.

edit: making it more "prone"

My # 4 ringland cracked and I am also using a skunk 2 im. hmmmmmmmm

The skunk 2 intake manifold has nothing to do with a ringland failing.

The issues you are addressing are primarily related to tuning and tuning alone, not skunk 2's product.

My number 4 went on my old motor and the number 3 went on my current motor. On OBDII cars, the knock sensor rarely picks up detonation from these cylinders as the sensor is closest to cylinders one and two.

I have no signs of detenation on my plugs whatsoever. The car still pulls hard however the it idles rough. I'm going to scrap my skunk 2!

and you blame your intake manifold for your ringlands cracking?

Chillinit

no Dennis...I trying to figure out what the culprit is..thats all. Is it just bad luck?? I'm sure stock blocks last a little longer then this, especially if they have been tuned. The common component between the two setups were the head and the intake manifold.

Just sounds like a tuning issue. Probably too much timing. The #3 cylinder is the most common to break first, since it runs the hottest.

About the knock sensor, Honda knock sensors don't work in the upper RPM ranges (5K and up), so even if you were detonating, the ECU probably wouldn't pick it up. Also, most people that run Hondata, are running a P28 that doesn't have a knock sensor functionality anyway.

Chillinit

any other suggestions? could a faulty injector be the cause?? I was running for about 1 mouth....3000 kms

my last motor(fully built/sleeved) melted #3 and i had a skunk2 IM. also had hairline cracks on the intake valve cuts on #1 and #4...#2 was perfect tho

drvfast

Its number 3

Can someone explain why #3 runs hotter than the rest?

I have to agree. its in the tuning

firing order is 1-3-4-2 so 3 shoots then 4 (right next to three) then 2 fires (right next to 3 as well)

wow i never knew that. but if you are correct then wouldnt it be the same case for #2 since right after #2 fires #1 does also followed by #3 which are both right next to #2???

when you guys are staying its in the tune, do you mean the tuning is to aggresive??? (timing) You can few my air/fuel in my sig....

Well if the manifold doesen't distribute the air properly and provides one cylinder with more air you could run lean on a cylinder. That really seems odd that two motors running a skunk manifold experienced failures on a cylinder.

Chillinit

up

Griffin@Camtech

Looks like timing to me and maybe slightly lean as well

plugs look fine, they are a dark gray color...I will try and post them sometime tomorrow

The #3 ringlands went in my H23. Somehow the rod got broken off too. Weird crap.

numba1

Also in my motor the ringlands broke in #3.

Rod broke in cyl #4 in my last motor
