Re: quick oil question
I wouldn't reuse engine oil that has drained out due to possible contamination. I'm not familiar with a 'filter housing cap'. If you mean the 'oil fill cap', then no, the oil won't drain out. If you break off the oil filter end (the part that a wrench attaches to - not on all filters) then you have to replace the oil and filter. Do not resuse.
Your question is a bit confusing. Please also state the year, engine and mileage of your vehicle to better assist other members in helping you out.
