ok to keep it guys updated until now the SES light didnt come back again, i guess the MAF needed to be cleaned, saved me couple bones lol... i also had my valve cover gasket changed, baby X was oiling pretty good so i had that done and now no more oil leaks

i also noticed when the valves were taking off alot of slug buildup was there.. i have my oil changes done on time ( Mobile-1 & BMW oil filter) but whoever had this baby befor didnt care for this X, which made me get pretty mad about it. so i cleaned both covers and mad it spotless with any buildups that been there, but weasel am sure i have alot of slug inside the engine or the bottom of it, is there anyways i can clean that out without taking the engine apart?..
i also changed the sparks plugs and both oil vent hoses & when he pulled them out they were almost like pulling gum out & also one of them was cloged up
