Hi my peugeot 308 is using more oil than usual and the oil pressure warning sign keeps coming on but no obvious signs of an oil leak

After cooling, check the radiator water for signs of engine oil. Oil can be forced into the water cooling system through faulty seals or gaskets.

Oil getting into radiator/cooling system?

Hi Alan, If your vehicle has been overheated at any time, the cylinder head may have become distorted and consequently coolant may be mixing with oil if the gasket is damaged and failing to seal correctly. The job requires the removal of the cylinder head and taking it to a machining company to skim it before replacing. You were quite correct to have checked the oil cooler if it is the type which fits into the engine block and uses the engine coolant for cooling. Oil in the cooling system is not something which should be ignored. Once the problem has been solved and rectified, flush the cooling system to remove all oil deposits and then use the correct mixture of coolant to water. Regards John

Heat was working until I added something called Steel Seal. Prior to that, had my water pump, thremostat, and radiator cap replaced because of coolant I was losing, but could not physically see the...

Well Reggie,

You have "steel sealed" your radiator, heater core, water pump, cylinder head ports and every other part of your cooling system. There is no such thing as "mechanic-in-a-can"!

The PROBLEM with the garbage that the parts outlets sell as "fixes" for cooling system leaks (steel seal, radiator stop leak, bars leak, aluma seal, block seal, etc.) is that they WORK!!!! They will stop up your ENTIRE cooling system!

Your problem probably started out as a simple breach in a head gasket. Now, thanks to the "snake oil salesmen" that managed to get your hard-earned money away from you, you will now have to replace the heater core and the radiator in ADDITION to having to fix the head gasket. I just hope that you have not destroyed the cylinder head(s) in the process.

I really wish they would stop selling that stuff.....It invariably does more harm than good! I guess the parts stores like the stuff because now you will have to buy a whole bunch more parts than you would have if you had fixed it correctly to begin with.

Water not going in moter ,white smoke blowing from rhe tail pipe

Hi, If water is Not going your cooling system, check : - cooling liquid level ( it should in normal level) - air lock in your cooling system ( You can run your ca for minutes then top up liquid to disable this problem) - water pump ( it should working normal and has no leaks on its seal)
White smoke blowing, please check : - Valve seals for leaks - Oil seals for leaks - Compression on your combustion chamber
You will need a basic knowledge of car system to do above tasks.

Audi a4 oil in the radiator system

sorry dont run it. The cooling system is a sealed unit with no way for oil to get it. Problem the system is allowing oil from acrack in the block- head or metal area to the cooling system. Maybe a gasket that is alowing the transfer in the head area.

I have oil in my radiator

Bad news :(
A seal is leaking and most likely the head gasket which is allowing high pressure engine oil to be forced into the low pressure cooling system.

I just bought a 91 mustang gt 5.0. The water pump is brand new but the seal is bad. To take it apart do i just need a new seal or does it have a gasket? and when i out it back together is there a certain...

Not a gasket but you may buy and replace the water pump seal for your 91 Ford Mustang GT. You may find the seal in any auto-part Web sites.

There's no certain way the timing belt goes on. You just have to make sure that the belt is tight enough so that you could be sure that the car would run properly.

But check the instructions below and it might help you make the task easier:

1. Begin when your car's engine and cooling system are both cool. Thefirst step is to drain all the oil out of your car's engine. Collectthe oil in a drain pan, so you can reuse it later.

2. Remove your car's fuel tankmag-glass_10x10.gif,so you can access the radiator if your engine is mounted in such a waythat the radiator is buried beneath the fuel tank. This is notnecessary for all vehicles.

3. Drain all the coolant out of your car and into a second drain pan.

4. Locate the pump seals and loosen them by hand or with a rod. Use ascrewdriver only if it's absolutely necessary, as you might scratch thesurfaces of your pump seals if you're not extremely careful.

5. Make a mental or written note of the direction each seal is facingbefore you remove it. You'll have to orient the replacement seals in anidentical fashion to ensure your water pump works correctly once you'refinished.

6. Remove the seals you want to replace and set them aside.

7. Align the replacement seals in an identical orientation to the oldones, referring to the note you made earlier. With most engines, thespring side of the inner water pump seal faces the engine, and thespring side of the outer water pump seal faces the impeller.

8. Protect the water pump seal springs from rust and corrosion bylubricating them with a little oil before you fasten them into place.

9. Refill your car's cooling system with coolant or antifreeze. It's fineto reuse the coolant you drained earlier if it still has some lifeleft. If not, be sure to dispose of it properly and in accordance withyour state's hazardous-waste guidelines.

10. Reattach your car's fuel tank if you had to remove it in order to access the water pump seals.

11. Refill your car with oil. Make sure that you have appropriate levels ofboth oil and coolant in your car before you drive it again.

Hope these helps and have a great day!
