HUGE leak HELP

[775DSM]

Something is leaking pretty bad by the timing belt. It is oil it is running all down the side of the engine puddling up in the Oil pressure sending unit. It is spraying quite a bit down the bottom of the car and leaving puddles where ever i park. I installed a new 16G but it was leaking before this. I am losing alot of oil pressure. My turbo was boosting fine at 15 PSI now it wont go to 15 it stops at 11 and bounces 9-11 and you can hear the turbo spool un spool spool unspool. I have half of my engine apart right now on that side mounts n such. It looks like its coming from the right hand side of my water pump / Head. My lower timing cover is SOAKED in oil. Looks like it has been going on for some time now due to alot of build up on the inside of the timing cover and all. Any suggestions what this leak could be from. I have a brand new gasket set and im ready to replace some gaskets. Also what is the best way to get those pullies off. Do i have to take the head off to remove the timing equipment. I do not have a cherry picker or this would be alot more fun

My oil was full and i drove 100 miles and it was damn near empty so this is no small leak.

Hey, I just replaced my headgasket, and the only thing that can leak on that side is either the valve cover gasket or the cam gear seals. And as far as the pulleys go, you just loosen the bolts before you take the belts off, then take the belts off and remove the bolts. They should just pull off, no special tools needed.

Im thinking cam seals. Looks like there is a little puddle of fresh oil where the gear for the timing belt goes. Im going to replace those put the car back together n clean it up. I cleaned off my water pump surface so ill see where the fresh oil is coming from. We will see what is going on hopefully by monday.

HOW important is the cover the goes around the timing belt. Other then its used to keep things from cutting it. I broke mine up quite a bit and i dont wanna dissect the whole engine to replace it.

Also when i pull off the gaskets around the valve cover n stuff they have silver paint or something all around them. The bottom end and top end of this motor is new. Head more so. So i am replacing all the gaskets again. The cam seal gaskets are brand new. So is the head gasket. I really dont wanna take my car apart ne more then i have to. There is some wet around the valve cover gasket with a new gasket. Also wet around Cam seals.

don't forget about your front main seal

What Pulley is to the right of the timing system above the axle?? Because the bottom of the housing is covered in oil. Where is the rear main seal?

 

[775DSM]

don't forget about your front main seal

Where is that?

 

[DSM1G90]

Front main seal is behind all of the sprockets that is mounted on the crankshaft. You have to pull all of that off to get to it. The main seal is part of the oil pump assembly housing.

Where is the rear main seal?

Rear main is behind the flywheel..

What Pulley is to the right of the timing system above the axle??

That is the idler pulley-if your talking in the middle of the belt system. Otherwise, down low, that is your oil pump pulley...which has to be timed a certain way if you still have the balancers behind it. Otherwise, you'll get horrible vibrations if not timed correctly. Check with VFAQ Site - Visual Frequently Answered Questions for timing procedures.

The cost of the seal itself is quite cheap - less than 10 bucks, but you gotta be careful in removing that seal being that it's right there on the crankshaft itself. If you nick the shaft, that is a "goodbye" to ending the oil leak with a new seal.

Also, if that main seal is all but rock hardened up, there could be a possibility that the hardened seal has actually cut a micro groove at that section of the crankshaft where no seal replacement will end the oil leak.

That is when the crank itself needs to be replaced.

Damn thats nice. My car does have a high idle. It idles at 2000 RPMs then drops to 1500 and back up 2000 when i take off. It is a bad leak. I did find a little bit of oil in the cam seals exterior (replaced both). Nothing looks like it is leaking inside of the timing systems. But to the right of my crank and above the axle is a housing with a pulley. The housing has a bubble to it. I mean its a pretty big housing. Is that my oil pump? It also looks like my oil pan gasket was tightened down way to much and looks smooshed / melted. Wish i had pictures. But any more info would be great. WHAT could leak on that side of my motor in or around the timing area. From the cams to the crank or oil sending unit??? Need help asap. I need my car back up and running by monday. Thanks.

Are you getting oil on your timing belt?

 

[775DSM]

a little bit. little in the housing. And ALOT on the bottom frame Oil sending unit, Alternator, lower power steering lines and such. I mean the bottom of that Pulley housing what ever that is is fricken COVERED bad. All the way back. My oil pan is soaked on the back side so is my oil pan gasket. I have oil all the way back to my muffler but on the driver side. (muffler comes out passanger side). I cant really tell whats leaking and i cant get to any of this stuff well enough to clean it off good. I cleaned off the top end such as Cam seals timing case and such. My axle fender well and inside of tire all covered in oil. Man i dont know what is leaking this badly. But It is leaking VERY VERY badly. While my hands are clean im going out to take pictures.

Start the engine and let it run, If it is a large leak, you have to see it when the system builds pressure.

 

[DSM1G90]

Yep, looks like the front main seal has let go...

Wanna see a shot front main seal- what they look like when they go?

Normally, the entire seal is a soft rubber compound to flex around the crankshaft, but this seal is solid rock hard. You can see the cracks around the inside parameter of the seal. The motor (a 4G37, 1.8L) that this seal came out of was leaking oil so bad that you had to put a quart in every other week. The underneath was totally soaked that I had to get my power washer out, with the rig up on the ramps and power wash the entire undercarriage.

Unfort, with the seal being rock hard as it is, I'm afraid that the edge of the inside of the seal cut a slight groove in the crank, to where I did the replacement, but it still leaked a little bit, but not like it was before.

so i after i remove the oil pump i should be able to tell if a seal is bad? Im going to start on that. I cant get a couple of pulleys off tho. Illsee what i can come up with.

Damn i dont have the tools nor money to fix this. I dont have a Key or a pulley puller or the Crank tin. So i guess im screwed with a leaking talon. Anyone wanna buy some parts? Ill part it out!

Any other ideas on how i can take this thing apart?
