Those products do not work

Just make the proper repairs

Once you add them, they can not be removed,
short of a hot tank or acid bath during a rebuild

You can find anything you want on the internet

You will just ruin the vehicle for the next owner

2002 Buick Century fuel odor

The oil pan is on the bottom of the engine, so any oil leaks from the top or front of the engine could drain down and look like an oil pan leak. It's important to verify that there are no other leaks before having the oil pan resealed. Repair cars by diagnostic tool.

Water leak at the bottom back right of the engine comeing from the temp plug

This sounds like the block heater for your car's engine, the engine coolant heater with a cord that you p[lug into household current to keep engine warm during very cold nights. It makes for easy starting/warm-up of the car on cold mornings.
Use a small socket on the screw (I think it is a 5/16 head screw) and see if you can tighten it about a 1/2 turn or less (or until the heater element rim is snug against the engine block) to try and stop the leak. If that doesn't work, it will need to be removed to reseal it. This means you will have to drain the coolant from the car first. Then loosen that screw several turns to release the clamping-type wing nut on the other end of the screw inside the block. There is a rubber o-ring around the element that is leaking. Pull the element out, and watch out for a cup or two of coolant to also drain from the engine block. Now you have it out, you can decide whether to just replace the o-ring, or buy a new block heater with a new o-ring included (they're not too expensive), or just install a new freeze plug (like $2.00 at a parts store) in the hole if you don't care about having the block heater on your car. Be sure and clean the area well, around and inside the hole where the o-ring goes, so you get a good seal when you put it back together.
Good luck.

Is there a product made that will stop oil leaks I'n northstar engines


Gunk M2112 Engine Oil Stop Leak OR

Gold Eagle Engine Stop Leak Safely stops engine oil leaks. Compatible with all engine oils. Prevents costly IF none of these products work I would recommend cleaning off the lower half of your engine with some brakleen and checking to see how quickly it leaks. Most crankcase leaks do not leak as much as they seep. If it is seeping or has a slow leak you can clean the crankcase at oil change and you will probably not have any oil dripping from the underside of your car. If that is the case that small of a leak in my opinion doesn't warrant resealing the crankcase. If you do have a major leak and need to reseal the crankcase, you do not need to remove the engine. You do however have to remove the transmission and the cradle and hang the motor with a fixture. When resealing the crankcase, for best results use factory gasket sets and make sure all surfaces are very clean and and do not have any nicks or scratches. also use an anaerobic sealer in addition to the rubber gaskets, and make sure to properly torque all fasteners. As for everyones oil consumption complaints all Northstars will burn some oil. GM says up to 1 quart per thousand miles is acceptable. If you are using multiple quarts between oil changes you may consider performing or having the dealership perform a top engine clean. This will loosen the carbon from the top end of the motor and help free up sticking piston rings. The Northstar motor runs hot and has a tendency to pruduce a lot of carbon. In addition to this using an in tank injector cleaner will help the motor stay cleaner and burn less oil. Another common carbon problem will be in your throttle body. If you feel the accelerator pedal beginning to stick you should check the throttle plate and throttle bore for sticky carbon build up. It is easily cleaned out with some carb cleaner and a tooth brush. Hope that helps. Good luck,

Antifreeze leak from timing cover.4 litre engine not a SOHC

Your water pump has a 'weep' hole that is breached so you are going to have to replace the water pump. that engine is not overly difficult to work on as you have lots of room to work.

There is a small oil leak in the engine seal. My mechanic showed me where it leaks and that because the seal is permanent, the engine has to be taken apart and resealed at a cost of about $1,000. He...

$1000 is not that much to spend on a seven yrear old car, but if the leak is minor just ignore it, and keep an eye on the level, you could try an oil additive, some expand seals ,

I have a 97 caravan. ive gotten the transmission resealed, but is still leaking fluid. what do you think it can be??

What did you have resealed the oil pan on the transmission? there could be anything causing this including a bad radiator that's leaking fluid if it's towards the front of the car then it's there if it's between the engine and transmission then it may be the front pump seal or the tork converter seal.

Oil leak

What is the mileage on your car? Is your engine a 2.5 L?
Clean the bottom side of your engine with engine degreaser first to determine exactly where it's leaking. Run your engine at idle speed for fifteen minutes, then inspect the bottom towards the front of engine. If you see a drip on the drivers side center, don't waste your time or money replacing the crankshaft seal or oil pump / pump seals. I have recently done that and still have a leak........coming from where......who knows! I have posted a question on this site, hopefully someone can answer for both of us. I know we're not the only ones with the same problem on this year and model.
