Oil leaking into coolant -- not head gasket

We have a 99 Acura CL 4 cyl 2.3 CL. There has been oil leaking into the coolant. We have had the head removed, pressure tested, replaced the gaskets, flushed the radiator and it is still happening. Any ideas?

    The car is a manual so the so it doesn't have a tranny cooler.

  • jandsmarq May 28, 2009

    The head was pressure checked and it was checked for cracks and warps and they said it was flat. Don't know if it was hot tanked but it was clean.

    They did not replace the head bolts, but they torqued down ok.

That vehicle has the transmission cooler built into the radiator. You may not be leaking oil into the coolant, but transmission fluid, they both make the same mess. Replacing the radiator will probably fix your problem. Let me know if this helped.

    Sorry I just assumed, most of those vehicle's were auto's. When they replaced the head gasket, did they replace the head bolts, they were bad about stretching and not going to the proper torque.

Engine oil mixing into coolant

The only place, oil and water share a gasket is the cylinder head gasket, oil and water galleries run through the engine block and head via the head gasket. The cylinder pressure will be OK, it's the oil pressure that's putting the oil in the coolant, the gasket has gone between the water and oil galleries or there is an internal crack (unlikely). A coolant pressure test should show it up.

Acura cl 97 is leakin oil bad what couuld it be

You probably have a leaking seal. It all depends on where the leak is coming from and how bad it is. More then likely, it is a seal. Make sure all your bolts are on tight. They come loose after a while on the head and then they leak.

I have a 1999 acura cl. There is oil in the radiator and coolant overflow. It is not overheating and loosing very little oil. The hose are now getting soft and gummy. There isn't any water or coolant...

It seems there could be a blown head, if there is oil in the radiator. If the car ran out of oil and it was still being driven, then that could have overheated the engine and maybe warpped the a piston. Sometimes when the oil is changed at some shops they may not fill the oil back to the capacity it should. This could make the oil run out faster if it is not filled back to the appropriate level Nevertheless, check the oil level. If it is the head it should be sending smoke out of the tail pipe.

Leaking coolant from head gasket area and valve

Well the head gasket job will cover the valve cover gasket ( you have to do one to get to the other) Bring it to a repair shop its about a $1500 job.

I just changed the thermostat on 3.4 L 1999 Pontiac Gr Am GT THINKING IT WOULD FIX THE OVER HEATING. But there is white steam coming out the exhaust! The oil is not milky so it's not a head gasket. There's...

Are you adding coolant?
Yes ......means it's going somewhere.
Fill the coolant tank to the top...right to the top....leave the cap off and run the engine.
If you see bubbles you need a head gasket.
The intake gasket is another source of coolant leaks and at this area the coolant can be sucked into the engine and produce a white smoke.
Does the car run rough at the first start in the morning....could be antifreeze burning off in the cylinder or area that was leaking overnight meaning cyl gasket or intake gasket.
Look at the rear head to block area below the exhaust manifold.
Is there any trace of coolant or stains of coolant......yes means head gasket time.
Pressurizing each cyl at a time with air with the valves closed in that cyl will quickly show the location of the bad head gasket with bubbles coming out of the fill tank on the bad cyl (s).
Head gasket leaks don't always mean milky oil.

Do the block chemical leak test and coolant pressure test to rule out blowning head gasket.
Check all freeze plugs to rule out coolant leak on the hot engine block.
Check for any hose leak.

Start monitor for coolant and oil lose.

My 1997 acura 3.5rl has been giving out white smoke from exhaust pipe for almost a yr now. when i first reported here someone suggested it could be due to a leaking gasket or broken head gasket or block....

it does sound like a head gasket allowing coolant into the cylinders and burning which creates the white smoke. a head gasket is a large job which requires you pull the cylinder head from the top of the engine. auto parts stores sell head gasket kits. you would also need the propper torque specs for the head as well as the sequence for tightening the head bolts.
before you go about replacing or having the head gasket replaced have you been losing coolant. is there any oil in your coolant or coolant in your oil your engine oil will look milky.

as i'm not familiar with an acura is the enginge a v-6 if it is it could also be the intake leaking as most v-6 engines cycle coolant through the intake manifold and can send coolant ito the cylinders if it is leaking.
