Weird sound and oil problem

[xinghonh]

hi bros
im driving a satria with 4g93p bolt on turbo
my prob is...when im revving at ard 3-3.5k ...there is this weird wongg wonggg sound occurs....it doesnt matter whether im in 1st 2nd or any gear...the sound will occur at that rpm...when it passes the 3.5k mark, then everything goes back to normal...
2nd prob....my engine oil i checked....it decreases to minimum level after travelling only for about 1k km....i dun see any leakage or what so ever....
plz help!!!:wavey:

if no leakage of oil then maybe ur engine makan minyak, your exhaust got blue smoke or not?? maybe piston ring worn out...

i hv that kind of wong wong sound also, i think it's resonance in engine bay, when you rev over 3.5krpm then engine sound is too loud to resonate... just my wild guess lah...

if engine oil degreases so badly, i suggest u to change piston rings + main n conrod bearings + head gasket....
i had this prob last time...dun see white smoke or watsoever....
end up decided to change all the above....when take out, found dat main bearing "makan" edi....piston rings also not very nice....
once done, its superb...just like new!!!

engine makan minyak ...should check if any blue smoke coming out the exhaust....depends on what oil viscosity you are using too....if CONFIRM no leaks..should be valve seals or piston rings...

about the leakage you checked your self or mech check? must becareful when checking...sometimes near the seals area will have a very mild leak..need to check all surroundings...

when you park your car overnight...do you see any oil visible on the floor?

thnx for the replies
first of all...i dun see any stains on the floor when i parked overnight
secondly...there isnt any blue or white smoke coming from the back of the exhaust
my mech did checked before...but he juz said mayb oil nt suitable...using semi syn 10w40...
bout the noise prob....it gives some sorta feeling that makes u think that the engine gonna break down soon...lol...
