Engine problems! PLEASE help!

[Apolan]

hi!

i dont write much but now im gonna go all out.. please read and help. tnx!

so yesterday i passed MOt and stuff and finnaly got the thing registred. all that whit a lot off begging and sad puppy looks.. "mister i spent all my monney on this car and i will continue to do so.. just please let me pass.." and similar; so im running legally now.

PROBLEM NO 1:

but as soon as my joy of actually driving a street legal car began, so have my engine problems. ironically, on my first street legal drive i noticed wierd pinging sound. so i checked the sparkplugs. when i disconected the first sparkplug the sound stopped. so i pulled them all out to discover that plugs 2, 3 and 4 are okay, a bit shaded, but no1 plug was death-black, burned to oblivion.. still with this problems car acceralated very good. probbaly the same as when i hadnt had this problem.

so what can this be? note only 1 plug was black, only when i cut the 1 plug does the pinging stop. car goes just fine.. i have ridden a bit yesterday and did some doughnuts (at least my lsd still works)..

PROBLEM NO 2:

today it started raining and i just couldnt resist the sliperry surface-sucky tires combo so i gave it a shot on an empty parking lot.. drove there for an hour or so, and no changes were noticed. the pinging noise was still there but the car drove just the way a 21 year old should.

then i went home to do a couple of laps on gt4.. 2 hours later i went for another drive w/ 86. i went to a "circle-crossing" (hope you understand) and drove in circles trying to drift. the grip was really god so i didnt drift in stead i just made some 5 or 6 laps as fast as i could.. then i noticed a HUGE cloud of white smoke (like a camaro ZL1 was doing a burnouT). its just that it wasnt tire smoke but oil burning in my engine producing this REALLY HUGE smoke cloud.. i thought that was it, im done for.. then the car choked a bit, and i went on as nothing ever happened, the car drove as b4, and accelerated as b4.. :confussed:

i came home and opened the hood and noticed A-lot of oil spilled around my airbox.. so i thought that some oil line broke or something, but there are no oil lines nearby. opened the airbox and discovered my soggy airfilter, dripping, covered in oil.. there was also oil dripping out of my throttle body & manifold !!!

so what the fuck happened? oil dripping from manifold, car drives as it was b4.. and no more white smoke from my exhaust.. and the oil level was still at HI mark.. wtf??!

PLEAAASe help me on this 2 issues, im scared to drive my car anywhere now..

tnx a lot, sašo.
