    This possibly could be that the old gasket from the previous oil filter has stuck to the mounting base for the filter and now the filter has (2)Two gasket seals on it causing a massive leak.

It could be the oil pressure sensor for the oil light or guage.I have seen this before after age and heat plus vibration could cause it to crack and leak a lot of oil like you describe.Get it fixed asap.It should be easy to unscrew with a wrench or large socket .Buy the new sensor first though so you can replace it once you get the old one out.It leaks alot because of oil pressure from the oilpump pressurizes the rest of the engine bearings.It could break altogether and pump all your oil out and ruin your engine.

Loud lifters


Good you changed the oil. Keep an eye on it. It should stay a nice clear color for about a thousand miles. Sounds like a lifter is bad. Good idea to change them all if you change one. If it doesn't get worse, and doesn't cause any other problems, some people just live with it.

2001 Sunfire 2.2L, Car started Noise seems to coming from top of Eng . Lifters is my guess, is there anything that would make similar noise, or that I should be checking, How can I be sure it is lifters?


You make have a bad or sticking lifter, remove the valve cover and have someone tap the key, make sure to disconnect the ignition coil to avoid the engine from starting, as they tap the key you will look for the valve to close, a good way is to watch the one next to it open, when the valve is open then you will know the other is closed as there are two valves per cylinder. with the valve closed grab rocker arm and see if theres a lot of play in the direction it moves if it does then look at rocker and push rod and if those are good then you have a bad lifter. if this engine use an overhead cam then there will be no rocker arms or push rods you will need to look for any worn lobes on cam, a stethiscope would be a good tool. start engine with cover off and listen to each cylinder and pin point noise, this will get a little messy as oil will be splashing out a little but its the best way to locate the noise. poor oil flow would cause this also or a loose timing chain. i would start at the top first and look inside cover. good day.

I had the valve cover gasket changed on my 1996


on a v6 ? Low on oil? rear cam plugs leaking? The lifters are on the end of the rocker arms and may get clogged. I have had some luck running 0w30 mobil synthetic for about a week or so with a new oil filter [Not a fram filter] and after that put 10w30 synthetic oil back in and a new filter. Check for oil leaking at other locations. If the noise is at the front of engine near water pump it may be the hydraulic timing belt tensioner.

Motor ticks


Lifters sound like they are bleeding down. Try changing the oil with a multi viscosity oil. chk oil Pressure. If lifters are over adjusted the lifters can't pump up properly or retain the oil properly

Ticking noise when i first start the car then after driving a few minutes it stops?


DEPENDING ON HOW LOUD IT IS IT COULD JUST BE THE HYDRAULIC LIFTERS. THE NOISE STOPS WHE THE MOTOR WARMS UP AND OIL GETS TO THE TOP END OF YOUR ENGINE. THAT IS NORMAL.

Loud ticking noise on startup


I would have you oil pressure checked. The oil pump or bearings could be going out. The lifter noise on this car usually will go away faster then 5 minutes. I think the noise is lasting a little to long.
