My plugs were destroyed...

Starting from last week I started hearing clicking sound from my engine..I posted this earlier and have been discussing it with George aka.P10DET Anyways, today I checked my plugs....They were toast...I have never seen anything like this before...I have JWT cams and I think they are S3 cams. I also have Stillen headers, intake, exhaust, magnecore wires. I have 60K miles. Tomorrow I am going to buy another set of plugs and put my stock wires back. Can anyone help me on this? I have read around and seems like pre-ignition is the case which they say leads to detonation!!! Please if anyone have any idea or know the answer please help me out...


This is the picture of all four starting from left to right, cylinders 1-4

Surprising my car ran very well even though my plugs looked like this...honest to god truth...I called my friends to come over and they were shocked to see that I drove with plugs looking like that. I was surprised my self but reading alot of info on plugs reveals I could have seriously damaged my engine...

Hmmmnn ... the other symptoms (clacking vs rpm) indicate there is probably still an issue with the HVLAs.

Perhaps they are they root cause of the burnt plugs, due to unusual fuel/air mixtures, if the valves were not operating correctly because of an HVLA problem in #3 & #4 ??

Bugger!
(sorry not much help....but I'm feeling for ya bro)

d00d! Man your car will feel soooo much better when you get the new plugs in. I'm betting that might have happened when you were playing with the S-AFC? :confused:

a little off the subject.. but did you say you "think" you have S3 cams?? :confused:

Did the tips break off those plugs? If they broke, then i would check the valves and the pistons to make sure there is no damage to them.

Yeah I think I have S3....I got these for a power page in Import Tuner magazine. The magazine did everything for me but they didn't know what cams they were when I asked....I called JWT and they said that they don't remember since its been awhile...Only way is for me to measure the lobes and specs then they can decifer which ones I have.

I don't have the S-AFC anymore...I took that out over a month ago...

Do you have any side view pics of the two "good" plugs? They look fine to me, if they are, this would look to be a fueling problem on those two cylinders. More than likely you have two clogged injectors, or low fuel pressure due to a clogged filter, failing fuel pump, etc.

Good God!! Ive never seen anything like that before...Hope you find out what the problem is.

check if there is coolant leak in your cylinder. is any of the cylinders corroded on the walls? if so you should get that fixed.

Your numbers 3 and 4 cylinders have serously detonated.

You MUST find the cause of this problem.

You might want to have someone scope those cylinders. Find a shop with a boroscope and have them check it out. The boroscope will allow the tech to look inside the cylinder.

Bad news dude. Sorry to bring you that news.

Bad news dude. Sorry to bring you that news. Yea the last time I saw something like that it wasn't good. It was a NOS mishape:( Hey Geo you and Grover gonna race Sunday?

That looks like a serious problem I have never seen anything like that before. Ouchies

Grover is going to race. I think he wants me to, but I just want to work on set-up. Strange huh? I may race though just to try the set-up out. You'd think I'd jump at the chance to race, but I'm just not as interested in racing in NASA. Maybe I'll feel different about once I get there. I'll be bringing all my gear of course. :D

I'll bring the consult and what ever you guy's need. Maybe try to drag Shell and Vinny along too:)

ok....bad news....my motor is blown for sure.

today went to a friends house and checked compression...

Cylinder 1 = 140
Cylinder 2 = 155
Cylinder 3 = 100
Cylinder 4 = Also somewhere around 100...and after that I didn't really care since my motor was fucked anyways.

Well I am going to do a link down test next week and see whats damaged and what was the source of this...

How much is a used SR20DE? How much are OEM internal parts?? which is more worth the money? I know I have to wait and see what parts I will need to fix but for now I want to know prices.

I am also considering selling my 1999 G20t Black/Black 5-Speed manual.

ouch sorry to hear :( what is the stock compression supposed to actually read around? you could probably get a used SR20DE for around $800 and the OEM internals would cost a hella lot more, so id suggust getting the motor. if your tranny is ok then that would be easy to swap a motor, plus yours doesnt come with the roller rocker motor so even better. :D

Well the parts I don't think are that bad...I think its the labor that will kill it. I am considering a motor swap but by law you need to put a 1999 or newer motor to be legal.

Time for a DET! :D

guess you missed it :p

You could always just get one of the imported Primera engines from SR20developement, or maybe Soken or somewhere like that. I know SR20developement probalby has a couple regular SR20s, and probably can get DETs or VEs in pretty easily, if you wanted to do something like that. That sucks, a local SE-R person had a similar mishap on the dyno, but with all 4 cylindars, due to Nitrous :( And he had everything setup right w/ the JWT kit and everything... :(

Just a fact of life when you're moding cars. If you can't take the risk you shouldn't be doing it. :D
