Good day Scotty,
I am a big fan of your work and love to watch your videos here in Australia.
My car has 36,000 or so KM, aftermarket accessories include: HKS Cat Back Exhaust, Eventuri CAI, Spoon Rigid Collars and Stiff Plate, Wheels.
I've had a misfiring problem with the car just this week after getting the car back from a 40,000km service at the dealership, the engine light will flash, starts to lose power and make a low purring sound as soon as the car is put under any boost/load(3.5k rev range). So I took the car back to the dealership, and they identified a misfire in cylinder no.4, and has given me a diagnostic report:
Tripped Code: PO300 PO304
And here are some picture of the spark plug and ignition coil: https://postimg.cc/gallery/syZWVtR
My question is:
1. How could this have happened to just the one cylinder?
2. Do you think this is a freak accident as the dealership claims to have not seen and is not covered by warranty?
3. How do I prevent something like this?
Thank you for your time,
Winston
The dealership claim whats shown in the picture is a mixture of "mud" and rust.
With all the modifications you've made, almost nothing is covered by the warranty any more.
Did water get there? Why do they look rusty?
Hey mate, that is also what I am trying to figure out...if the water came in from the intake it would have effected all four cylinder as oppose to just cylinder no.4.
Very weird issue here 🙁
Did you wash the engine bay? For some reason, water got inside the wells. Inspect all the spark plug wells and make sure they are not rusty.
I have not washed the engine bay once, and yes the cylinder itself was also rusted so evidently the water got into it somehow...damn I thought Honda could be trusted with proper seals 🙁
That's not mud, it's rust.
Looks like it could had alot of moisture in the tube & penetrating oil was used to get it out.
They also look like they've been in there for 20 years something that new shouldn't have anywhere near that. Have you ever driven say on an angle to get around a flooded road while part of the car was in the water? Gone through a deep puddle at speed?
If the problem wasn't there prior to the dealer & you didn't have some water adventure it's their fault. Tell them that they screwed something up/manufacturer defect, fix it at there cost.
Yeah man! For the past month It has been raining like mad here in Sydney, but I have not driven near any puddles as I live and work in metro areas...the water could not have come through from the air intake either since the other cylinders are squeaky clean, so how water managed penetrate that one cylinder only is a huge mystery to me {black}:idontknow:
That's odd. Maybe you hit a pothole which you forgot about or something that gave a good splash, it's not necessary for the intake to suck water for a plug tube to get some water in it, two different systems.
Also did you do the aftermarket stuff yourself? It's not unheard of for drinks to get dropped on the engine.
Just curious about the puddle swimming because that's how I "pressure wash" my undercarriage...I don't advise people doing so but this was all on vehicles that wouldn't suck water, etc.
Generally I hit puddles at 50-60mph & hydroplane creating a large wave you can feel pounding the floorboards.
I had to stop once I got a "new" vehicle as I burned out the G.E.M. in my 99 F150 doing that.
Ozzy mud looks like rust
Someone better tell that country to invest in POR-15 if they don't want to fall through the earth's (c)rust😄
