Small amount of milk in oil


To check whether the coolant is entering into the engine oil or not, do the following.
- Park the car on a level floor.
- Check engine oil level on the dip stick and mark it with nail polish. Let it dry. Confirm the oil level. Put the dip stick back.
- Apply about 10 psi external pressure to the coolant system, while keeping caps in place.
NOTE: It is advised to use the coolant system tester. In case the tester is not available, ask any technician to do it for you. Or you can use a bicycle pump with gauge installed on it to pressure the system up to 10 psi. The system should held the pressure up to 30 Seconds.
- If the pressure is maintained for 30 Seconds every thing is good at this time. Ensure that the air is not leaking through your external pump system with which you are testing the system.
If the pressure drops, there will be a leakage some where. Either external or internal. External leakage can easily be observed while carefully examining the hose pipes, clips and joints on the engine.
Internal leakage can be determined by checking the engine oil level again.
- Take out the dip stick and inspect the oil level. If the engine oil level increases it confirm the internal leakage.
- Internal coolant leakage could be due to:-
1. Cylinder head bolts loose or under torqued. (Re-Torque the bolts).
2. Burnt cylinder head gasket. (Always use original spares).
3. Cylinder and head surfaces warped. (Surface grind the cylinder head on surface grinding machine and replace the gasket).
4. Any corroded lid in the cylinder block or cylinder head assembly.
5. Oil cooler, if any.
If the test report of above mentioned procedure is found to be OK, start the engine, pull up dip stick a little, open breather tube from the tappet cover, keep it open and keep the engine start for as long as the water vapors coming out of these points disappear and the engine oil will become clear to its original color.
At times it happens that immediately after replacing the cylinder head gasket some coolant may flow into the engine unavoidably and keep contaminating the engine oil for quite some time.
Hope that works.
Thank you for visiting Fixya.

1994 Mazda B3000 V6 engine oil pushes into coolant. Have to add engine oil all the time and drain the recovery bottle. 65,000 miles. Never been overheated.


Failure of head gasket between cylinder head and block.

Because oil pressure is higher than coolant pressure, oil will creep across poor sealing area of head gasket from the oil riser drilling that feeds the cylinder heads cam assembly's.

Worst case scenario would be a cracked cylinder head/s. No totally unheard of but rare.

Continued oiling of the coolant system will rot out the coolant hoses from the inside to the point they will burst.

Due to the year of this engine it may be prudent to find a used engine with less miles and swap it out.

If this is a 3800, Upper Intake Plenum or Lower intake gaskets are an inevitability. Head gaskets on these engines rarely go out! Seriously, don't get duped. I am doing the job on my grand prix right now. Google it for further explanation.

Advice on purchasing a 2005 Chrysler 300 Limited with 98000 miles


Hello scottym88...The chrysler 300 engine is the weak point on this vehicle, the 2.7 litre was a major headache for owners, dealers and Chrysler...the problem was due to engine sludge, poor oil circulation, poor crankcase ventilation, faulty timing chain tensioners...etc...From 1998-2004 the Chrysler 2.7L was prone to Oil Sludge often caused by internal coolant leakage that has to do with the design of the Water Pump that allows coolant to enter the Engine over time and causes oil sludge...result..ENGINE FAILURE. For 2005, changes included improvements to the PCV system and improved oil circulation, to even later increasing oil capacity by an extra quart in an attempt to make the engine more reliable... Unfortunately, even with all of these modifications premature engine failure is common. I've seen this first hand...and the really sad part is CHRYSLER knows...yet refuses to cover prematurely failed engines even when under its own 3 Year / 36,000 mile warranty while blaming consumers for these problems.
If you want to research this further, check out the consumer complaints on this vehicle and/or the 2.7 litre engine. I have been a MOPAR enthusiast all my life, and in my opinion this was the worst engine that chrysler ever released to the public.
Good luck...i hope this helps answer your question..please rate me a fixya.

When to replace timing chain on 2003 Camry V6?


Replace the timing belt at 90,000 miles.

It will not damage the motor (bend the valves) if it breaks or jumps time

Finally, if you do change the belt, make sure that the water pump is inspected very close for any evidence of coolant seepage at the impeller shaft weep hole. If there is ANY evidence of wetness or leakage, replace the pump then. Easier to change the pump when the belt is off, than to have to do the whole job if the leak gets worse, and, if it leaks down the road, coolant on the timing belt will damage the belt, and you will have to buy a new belt, too. Change the plugs at 90 K miles, too.
