same car, same issues, but an idea

so car in my sig(ive made threads before), the cars gauge reads 0 oil pressure, and if the car is running the valvtrain is loud and obnoxious. the previous owner(2 days before he sold it to me) switched the car over to royal purple 5w30(synthetics of course ) and before the car had no issues as far as oil is concerned. now the idea is, i believe that when the oil was switched to synthetics, it broke down some of the grim inside of the pan or on the pump drive, causing either the oil pump to clog or the pump drives gears to be sheared. ive already drained the oil(very clean), switched it to some 10w40 and the car still has the loud valvetrain and no pressure.

now i know not to run the car or else my bearing will end up shot. but i do wanna get to the bottom of things...

pull the intake and check the oil pump drive and then pull the oil pan either way you need not start it again before you at least check those two or you will ruin bearings if they aren't already. Good luck

i have a tubular k, wouldnt that make pulling the pan easier? and what all is involved with pulling the intake, and what are the torq ratings? o0o and is there a way to tell on the bearings whether or not they are done for?

the tubular k will make pulling the pan much easier! as far as pulling the intake its not as bad as it sounds, taking the intake elbow all the way to the filter and then unhooking everything attached to the intake, just use simple common sense and pay attention to what your doing. as far as the bearings, look at your oil and see if you have anything metallic in it I don't know of any other way to check the bearings without removing the crank.

nothing was in the oil, i didnt think the intake was involved at all, i just remember on my npi mustang it was ****ty. now ive never pulled an oil pan before, but i would think it would be as simple as unbolting the y pipe, removing the oil filter, and unbolting the pan and sliding it out, anything else ill need?

if you have emissions I think they have a tendancy to get in the way but I can't think of anything else. make sure you remove the oil level sensor before you pull it otherwise you'll need a new one. (it will break if you try to pull the pan without removing it first!)

You can also take the filter and cut it open to check for metal particles in there.

When I changed my filter(car on the ground),I turned the wheels to the left all the way,so I could get closer to it,,then,with a plastic pan beneith the filter,used a filter wrench,slowly (counter clockwise) turning the filter off.Ware gloves,keep paper towels handy,big piece of cardboard on the floor.Let drain(drink something),use paper towels to gently wipe where the new filter is gonna go(clean it up).With the new filter,fill it up with new oil almost to the top,rub a little on the rubber gasket(filter),gently screw it on,hand tight,then just a little extra tighten with the oil filter wrench.My owners manual said by no way use 10-40 oil.Only 5-30 or 10-30.Hope this helps.But if you are reading no oil presure at all,check the oil presure sending unit.It is on the drivers side underneith side of the block,and is easy broken.It's covered in aluminum wrapping stuff.About 6 inches long.Man,it's hard to type with a beer in one hand.

with all the noise his engine is making I doubt its just a "broken sensor" oh and that sensor will be up on the top behind the intake on a 96 unless someone relocated it.

your trying to remove an oil pan and intake manifold and you cant even get the oil filter off get some huge channel locks and that will get it off, back to your original ques5tion you should defineatly take tha intake off first, more likely than not its the oil pump drive and you wont have to waste your time removing the oil pan.

If you put the beer down you can use both hands.
