crankcase pressure... .

[woojong]

i had detonation my engine...yesterday.

i had maf,stock headers,magnaflow 3"exhaust..

and powerdyne supercharger(i use 10psi)

ngk,tyler wires

now i am so curious.. whay made crankcase..pressure by supercharger...

and.. i dont have bypass valve..

i was plen to have bypassvalve and welbro fuel

pump in this week and will have cia headers in

next week...

i heard if i have 3"full exhuast system..

i might have blowby gas...

is it possible?

you might know~ i had detonation to my engine..

1time before..

at that time.. i messed TRC-1 installation..

that was problem...

so i spent 3500$ to engine..

this time detonation is..

i dont..know..

i think bypass valve or blowbygas...

i had blowbygas.. so.. i opend engine oil enterence cap~ so engine blowbygas coud go out

from engine... and i caped cotton istead of engine oil enterence cap~

so i could protect escape engine oil from engine

but when i ran engine for 1200mile

blowbygass...was getting more came out~

so finally.. engine was blowed..

when i chased slk230 i use high rpm.. at that time

i could feel i can catch him around 170km over..

but at that time i could feel somthing wrong..with

my engine... so i stoped..

and then i opened bonit~ blowbygas..was comming

out so much from engine oil enerence..^^:

with unstable idling...

now i want know... what is made crankcase pressure...?

and how effect crankcase pressure to engine working...

and..is my cars detonation connected with bypass valve?

Man, sorry to hear that you blew (broke, damaged) your engine again! Just not in the cards for you dude! (An idiom for "bad luck").

The supercharger will create crankcase pressure, it's a result of our stock PCV system not accomodating boost. You need to block the TB hole, open it to the air, and use a breather. But your problem may be different than that -- no guesses here, but sorry to hear it either way.
