Pod filter explosion

[toyrota mota]

So I got bored and decided to put this pod filter we had lying around on my mr2(4age). And from alot of photos id seen people put the pod filter straight on the tb. Yer yer i know this isnt the best way. But the standard filter was dirty as $&#$% and i needed to clean the tb anyway. And i just wanted to see how it went. So i cleaned and oiled the pod with sum k&n stuff and bolted it on. Went for a drive all was fine, no real gain as i imagined.
However I go to start it up today, it turns over once and theres abit of a bang and alot of white smoke starts coming out the engine vents. It appears that the engine flamed out the tb, like backfired up the intake. Because the pod filters all burnt and melted inside. Wtf? Why did this happen? The only reason i can see that would cause this, is the k&n oil dripping off the pod filter and down the intake into the engine.

Cheers

P.s. sorry about asking a pod filter question, but it exploded! Proably serves me right for putting a pod on haha

sounds like you over oiled it, and indde3d the oil went down the intake, and flamed out when you turned it over... would be cool to have a video of it, but probably not particularly good for the engine.

exploding pod filters.

what ever next



first thing id do, is pour some of that oil on the ground and set fire to it.
see if it burns.....


have you tried running the car since?

exploding pod filters.

what ever next

?

haha, i was thinking when i first read this that i didnt think filter oil was flammable......

[Mr Revhead]

thats why i asked him to burn some. to see if it burns!

if not... add petrol

lol, I have never heard of that happening. Spraying carb/throttle cleaner into the throttle with the engine running has never caused a flame to blowback in my experience, so I would think even less chance with the oil - assuming cam timing etc is all correct.

however, the oil itself is flamable & has a warning on the pack. I just sprayed a puddle of it on the bench and set fire to test. flame

[Mr Revhead]

good man


so have you fiddled with anything else? (on the car....)

[toyrota mota]

Yer theres three pictures on the front of the bottle of k&n filter oil, 1 of skull and cross bones(poison) 1 of flames(flameable) and 1 that looks like an explosion(explosive?) haha. Didnt think they'd make filter oil so flameable!
Yer i put all the stock air intake back on it ran fine. Only other thing i had done was use sum tb cleaner before putting the pod on. Oh and i had put sum of that morey's injector clean in the tank.

It was pretty warm 2day when i started the car and it had been sitting in the sun all morning. Maybe the filter oil evapourated and stayed inside the filter/intake manifold. How would it ingnite in a cold engine tho? When the spark plug fires the valves whud b closed. And how come it didnt do this the 1st time i drove it?

[Mr Revhead]

its possible that fumes were ignited by a spark, not nessicarily from the plugs them selves....

how much oil did you put on it? and how much cleaner? was there any still floating around?

begining yo sound like there was some fumes still there

I put a bit of oil on it but it was dripping or anything. Cleaner? Couldnt have been the throttle cleaner.
I cleaned the throttle, cleaned and oiled the pod and then put the pod on on saturday. Then took it for abit of a drive and everthing was fine. Now on monday after not starting it since, i start it up and this happens.
This is werid!
It wasnt a k&n filter just one of those el cheapo 1s I think.

i suppose it makes sense that filter oil is flammable, after all, you wouldnt want anything that wouldnt go bang getting sucked through with your fuel/air mix.... (like a water-based additive )

hmm, i can see a money making thing here.... anyone wanna buy some genuine hi-octane racing filter oil?

what is wrong with non flammable stuff in the engine? Heard of water injection? What about air being ~70% non flammable?

i was more thinking along the lines of thick goopy oil that wouldnt go bang...., rather than something like a water injection set up..... which is set up to atomise nicely....

[toyrota mota]

I guess if the filter oil was waterbased itlld jst evapourate

[mr30%jr]

bearing in mind the cold start injector is way up in the plenum it would have made a lovely oily petrol mix

[toyrota mota]

I still dont get it tho. Theres no way the oil could have dripped into the intake, it would only drip off the pod.

intake backfires are pretty normal if u are spraying or have alot of very flamible crap in there, one the GDI's at work we soak the intake manifold in throttle body cleaner then start them, can get sone crazy intake explosions, one blew the honey combe in the AFM to bits. usually the ecu gets the timing alittle wrong sometimes when u crank
