    F'Chatters:

    First of all thanks for the help over the years. Yesterday I discovered oil on top of my intake manifold which now has me in search of the cause. Also after starting and moving the car to check the pavement for leaks I noticed a small spot that turned out to be antifreeze.

    What do you all think could be the cause of these 2 issues?

    Did you overfill your motor oil - recent oil change etc ?

    Oil was changed over 5 months ago

    Check heat exchanger....could it be a leak on lines to heat exchanger (gear oil) ..what does it smell like..motor or gear oil ? .. can also be hoses to oil aerator /fill


    Clean as best you can and see where ..

    The coolant on floor can just be a weak coolant cap ..they are know to not last long and leak under pressure ..is it where the overflow tube is coming out if diffuser?

    It's motor oil. The coolant isn't coming out of overflow tube under the car. It's dripping from a hole in the under tray that's centered and in line with the intake manifold above.

    It was changed 5 months ago but was it overfilled? Have u checked it?

    This can occur after 5 months and on top of the intake manifold? If overfilled I would expect under the covers, correct?

    I haven't checked but will get it up to temp and check tomorrow.

    Looks like more oil residue on the back panel too. Engine bay looks very dirty. Start with a hell of a detail ,steam clean and have a clean place to start looking.

    To be clear What I'm asking is when it was changed 5 months ago did they overfill it then. Yes this can occur If they did

    Check oil level hot now.

    I got it up to temperature maybe even above, engine was at 210 degrees F, oil was at first mark, roughly 175, and oil was up to the top of dipstick I could not believe it so I dip 3 times and each time was at top. My independent did fluids 5 months ago and I trusted that he would fill it properly unless I completely go oil check wrong, he did not fill it right. I've checked oil a few times before so I know I did it correctly. So that explains the oil, but why did it take 5 months to do this?

    Also what about the antifreeze? I didn't see any signs of it today but I'm still concerned from seeing it the other day. I did notice that it reach ed 210 very quickly, 5 minutes, but never went over and dropped down a bit.

    UPDATE: Checked coolant and reservoir is completely dry. After further research I think this might be the dreaded heat exchanger failure. Symptoms seem to match, not much of a coolant leak on the floor but reservoir is empty.

    I'm taking to shop next week to get the full picture. My question now is should I add more coolant and run the risk of more getting into the gearbox if I have a failed heat exchanger?

    Don't do anything until it's checked out, if it's the exchanger then you'd be doing more harm. I wouldn't even start it until you know what's happening.

    Thanks, that's where I was leaning. Saw that someone else had the same issue decided to fill his reservior but never reported back. Hoping it's not heat exchanger after reading the horror stories of cleaning "mud" oil/coolant out gearbox.

    See if there is coolant in trans fluid.

    I am the person that you are referring to that had the exact same problem. Don't panic. That is exactly what I did, it was the wrong thing to do and it cost me a bundle.. First of all, is the engine running fine with normal parameters? Normal temps and oil pressures etc. My experiences are on a 430. There are two heat exchangers on the 430 one is for the crankcase oil and the other smaller one is for the transmission F1. It turned out to be one the coolant was very low and the oil was way overfilled. It looked to me like coolant was in the oil as the coolant tank was empty, Wrong conclusion. Transmission oil was clean and clear. My friends drained both systems, No water in oil and no oil in coolant. Pressure tested the cooling system for an hour and no leak. Pulled a vacuum on the cooling system and no leaks. Tested coolant for combustion products and no contamination. Refilled coolant to proper level with Zerex G05 and refilled oil with 10 quarts of oil. Replaced the radiator pressure cap. No problems since. I had to eat a restocking fee on the 1700 dollar crankcase heat exchanger because I panicked and was sure that was the problem, and ordered it before the true picture became clear. What I think happened is that I didn't check coolant very often and it was leaking out of the radiator cap that was 17 years old. When I checked it it there was no coolant in the expansion tank. Then checked the oil and it looked like brown clumps of water, foam and goo was 3/4 up the stick even when checking it cold after starting, thus leading me to the panicked conclusion wrongly that all the coolant was in the crankcase thus the very high brown muddy foamy appearance to the oil on the dipstick. What we believe to have been the problem was that the oil was way overfilled and that there was a slow coolant loss with a weak radiator cap and that the overfilled oil really foams severely and looks like it has coolant in it. I hope that helps. Good luck.

What I think happened is that I didn't check coolant very often and it probably had been leaking out of the radiator cap that was 17 years old. When I checked it it there was no coolant in the expansion tank. Then checked the oil and it looked like brown sludge with clumps of water, foam and goo was 3/4 up the stick even when checking it cold after starting, thus leading me to the panicked conclusion wrongly that all the lost coolant was in the crankcase thus the very high brown muddy foamy sludge appearance to the oil on the dipstick. What we believe to have been the problem was that the oil was way overfilled and that there was a slow coolant loss with a weak radiator cap and that overfilled oil really foams severely and looks like it has coolant in it. I hope that helps. Good luck .Lesson learned, check oil after every drive idling and with a welders glove on check the oil. At the proper level no or minimal foam. Park car and pull engine lid release. before starting the car prior to the next drive, when cold check coolant level with a flashlight and a ruler, It should be 1.57 in below top of filler neck edge on coolant tank. Monitor each of these fluid levels and you will get a better idea of consumption, and losses etc. I recommend replacing the radiator cap as that is the only source of loss that I could think of.

    No problem Snapshift. Thanks for your post. This sounds like my problem exactly. I really hope it is. I'm hoping there's space in my independent's shop to take it this week and have him check the transmission oil. Again thank you for the detail of your write-up this helps calm my mind substantial.

    UPDATE and Closing of Issue: Trans oil was good, no mixture with coolant. Covers were retorqued, shop said they were loose. Noted oil was drawn up inside covers and that was the source of oil. Didn't find any issues or leaks in cooling system. Coolant was refilled and system was pressurized. Drove it for 50 miles hard at times seems all is okay. Will be looking for leaks next few drives and drop in fluids. Thanks for all your help and again thanks Snap for your insight.

    Good news. Absolutely do not overfill the oil.( Mine took two 5 quart jugs exactly) Check it after a drive while hot and idling. Overfilling can mess up the throttle bodies. and end up in the intake manifolds. Sounds like you are all set. I replaced the coolant cap and I think that made a big difference in keeping the coolant level perfect. Check it before starting the car when cold. That is now my ritual and you get a better idea of consumption, loss etc.
