Thanks for ur help.

 

Just 1 cylinder? were any internal parts replaced, pistons, rods? were the head milled?

 

I know not.

 

Hey the SER Spec-V is nothing to be ashamed of. My friend has one (In pieces now unfortunately) and I loved driving that thing. I think the newer ones kinda suck but regardless... still a quick car.

Anyway, Hondatherdm brings up some good questions. Sounds like something is hitting within the combustion chamber. Did they look at the pistons and/or the bottom-end when they checked out the head?

 

a lot of carbon on top the piston?

 

wrong spark plug for application
crush washer missing on threads of spark plug
to much timing/ lean condition causing extremely high cylinder pressures
foreign object inside cylinder
rod bearings so bad that the piston travels to high

bending it during install.. thats all i got

 

Ditto the above ^^^.

Look at plug tip protrusion... http://en.wikipedia.org/wiki/Spark_plug 94

 

Well it bent it the ones i got from autoparts so my mechanic went to nissan and got ngk spark plugs for my car. After a test drive the plug in cylinder 1 was close as if something had close it or hit it. So after that i got a honda spark plug witch is almost half of the nissan but it still got bent so i dont know wat alse i can do. This is just happenig in cylinder 1

 

Add a second washer to the #1 cylinder spark plug and see what happens.

It is beginning to sound like there is some other problem, excessive carbon build up on the #1 piston maybe or maybe an improperly machined head, [flat but not level], maybe even the wrong piston or rod.

I can't see it being anything worn out, [wrist pin or bearing] as that should be noticeable with engine running.94

 

sounds like you have excessive carbon on top the piston bore scope the engine

this tool can be ur best friend!!

 

Indeed, if you can find a place/person that would rent one out/let you use it for a bit you could look right in and find out for yourself!

 

Well its sucks case my car has some problems like the butterfly srews tend to get loose and go inside the head and cause distruction and a pre-cat in the header mey cause the motor to go out so to get that out of the way im runing my vin # with nissan to if my car is one of the bad sentras out there if it is i would be in luck case they would have to fix it or even replace the motor at no charge. Thanks for all ur help guys i knew the honda family would help

 

Yeah I know what you are talking about with the pre-cat, among other things. There's no doubt some of these cars had issues. My friend has experienced just about every single one in his 2002.

Good luck with yours man.

 

My guess is that it was bent when he put it in.

He is saying that all the spark plugs he has put in cylinder 1 have all bent one way or another. Not just one.
