Last night on my way home my 95 z24 started ticking very loudly. I drove about 10 miles to get home and it was dark so I decided to wait and check it out this morning. The sound it was making sounded like really loud lifter tick. This morning I went out and started by checking the oil, it was fine. I started the car and the ticking was very loud sounding like very bad lifter tick. I shut off the car and oil poured onto the ground. I jacked up the front to try to look and see where it came from. I noticed that the oil filter gasket had blown out and all the oil was leaking from there. So what i think happened was that an oil galley got plugged not letting oil get to the top end and that the loud ticking was the lifters not getting any oil.
