my oil pan gasket may be leaking now.. i havent had time to check it yet, but i see no oil from the top of the engine, yet im leaking a good amount. So my thought is the oil pan. Is this something that can be changed with the motor still in place or does it need to basically come out?

I dont think the motor will have to come out. maybe drop the sub frame down a bit, but not real sure.

Wher e are you noticing the oil? Is it on the front or back of the pan and is it only in a certain of the pan or is it all over? Look for streaking, if you find areas with streaking you probably just need to check that all the bolts are tight. Mine loosened up on my a while back and all I had to do was re-torque them. Also check the 6 blackish windage tray bolts for tightness.

If that is not the problem then see below:

You dont need to drop the subframe to get the pan out if you have a cherry picker. Just undo the serpentine belt, take off the pass. side tire and fender liner, ubolt 2 of the ac compressor bolts and loosen the third, take loose the lowest starter bolt and loosen the upper one, remove the front trans mount (with engine supported), undo the upper motor mount but leave the aluminum plate attached to the motor.

Then undo all the pan bolts and any other bolts attached to the pan including the 6 blackish windage tray bolts. Lift the motor just high enough to get the pan down.


If you end up dropping the subframe you will need an alignment.

good news. I was right about it being the oil pan gasket leaking. BUT! i was able to fix it already. It had lost 2 bolts side by side. So i bought 2 new ones and put them in with LOTS of locktite. With luck this fixes the leak. I might run a bit of leak stop still though. I did see some oil coming from what im guessing is the oil pressure sensor. not much though. Strange thing is its not leaking from where it threads into the block, rather from the connection instead..

that is your oil descending unit, its bout 5-10 buck at a parts store and about 5-10 minutes to change, just remove the wire, unscrew, put new one in, plug wire in

um what parts store is 10 bucks? advance is 38... and rock auto is 18 plus shipping

No, thats the oil pressure sensor. It is not a very good sensor as it only reports low oil PSI when it drops below 5 at which point you have likely done lots of damage.

It requires a special socket to take it out or a pair of properly adjusted (not too tight) vice grips.

this is the sensor above the starter. not on the back ( right) of the block

Correct, the pressure sensor is slightly above and to the right of the filter (left of starter) looking up from below the car.

right, well ok at least i know what it is. whats the other one i talked about? knock sensor?

Yep, the other is the knock sensor.

Looks like my oil pan gasket is leaking....I pulled the crank pulley off thinking that it was the front main seal (crank seal) but it looks dry. It looks like the oil is leaking out between the block and pan right under the crank. I did double check all the bolts to make sure they are all torqued to 19lb.

Anything else I should double check before I tear the pan off?

try replacing your PCV valve.. many small leaks can be solved by replacing it. Epically if its not working properly.

You've pretty much narrowed it down. The oil pan gasket is an O-ring style with sealent at the front and rear cover areas.

While a faulty PCV system will reduce the amount of gas scaveging from the crankcase, it likely won't cause leaks as you still have the breather on the back valve cover.

Don't need to do anything like that... we just unbolted it and worked it out through the subframe, its possible. When you put it back in make sure you torque to right specs. you'll need some long extensions and possibly a pit.. +1 on the pit because it makes things go alot easier.

I don't own a cherry picker so that could be a problem but....lets see what else I find. I cleaned everything up so I can try to verify if that's definitely where it's coming from.

if you had to you could use a floor jack not really the best method but it works ive done it before.

WTH's a cherry picker? Isn't that a bucket truck?

theyre reffering to the engine hoist. everyone just calls them cherry pickers

I'm just used to them being called engine hoists... lol

stonemason90
02-09-2010, 02:03 PM
ive called them both but usually when i think of engine hoists i think of the fixed ones mounted in ceilings of shops and cherry pickers as the rolling ones

What is the right torque of those bolts? i gotta do it because there oil seeping from around the bottom of the block, so i know its that.

I cant say Ive ever used a torque wrench the two times I dropped my pan. I just tightened them up and then 1/8-1/16 turn past tight.

AKA Good'ntight.

Ive had no drips or leaks going on a year after my last pan change.

Here's what I got:

Oil Pan Bolt (bottom): 18 lb ft
Oil Pan Side Bolt: 37 lb ft

I have a leak as well, and it seems to be coming from behind the crank pulley too. I really dont want to do a complete replacement right now, but I want to do a quick fix for now. My idea was to just clean the area very well, inspect it for missing bolts or damage, then just try to add some gasket maker/sealer to seal off the area that its leaking.

Any other better quick fix ideas?

Here are some crappy pics I took:

i just unbolted my oilpan, and worked it out... nothing needs to be takin apart, with a little bit of patience... easier getting it back in imo. bolting it back in... takes awhile.

that doesnt look like a oil pan at all to me. looks to be 100% rear main. or is that front? these damn FWD motors always get me effed up.

Malaclypse

No, that's definitely an oil pan leak. If it was the front crank seal, the oil wouldn't be on the front of the pan to gasket area. Wind blows the fluids back while gravity carries them down. So the oil would be concentrated on the side of the pan and in the area of the crank pulley only.

Also, its important to tighten the oil pan bolts to spec because the pan is structural to the engine. It serves as a main girdle as well as mount for the a/c compressor.

i just fixed mine and it looked exactly like that. but alright i guess im just an idiot.

why a pit? I have the car jacked up a good 24" or so... whats the advantage?

just easier to move around on your feet than back. always nice to have more room than necessary.
