It Could Be Any Of The Three.Remove The Head, Have It Tested. After Checking Gasket. The Head May Be Warped From Overheating And Normal Use. If The Head Gasket Is OK. I Suggest To Have The Head Tested. But The Block Could Be Cracked. If The Car Has An Aluminum Head As Most Do It Probably Is The Head Is Cracked. Heck Run It By A Good Radiator Shop And Have It Tested Under Pressure. See What They Suggest. Sorry To Be Of Such Little Help. My Bet Head. Best To You
Water contaminated oil will be white and milky. Oil that is very thin and light coloured could be caused by fuel contamination.
there wouldn't be any coolant in the oil if your intake manifold gasket is shot. so its the gasket. A cracked block or cylinder head would render the motor unstartable, so that's a lie from the mechanic. Find a different one you can trust.
It would most likely be the head gasket as there is water in the oil. The rings would lose compression. Probably head gasket or cracked head or block. Most likely the head gasket. For sure not the rings. If you have aluminum head and the engine has been overheated, then a cracked head is likely. Also there are some weird engines are out there. IE some of the GM Quad Four engines have a water pump that is driven by the timing chain. If the seal goes bad in that pump, then water will leak directly into the engine. btw, that particular water pump is probably the worst and hardest water pump replacement job known to cars. Good Luck Rick
Engine coolant leaking into cylinder. Possible bad head gasket.
That would be part of the crankcase ventilation system. I guess you could call it the air filter housing to engine crankcase ventilation tube.
Any internal coolant leak can cause a milky residue in the valve cover. Head gasket, intake gasket, cracked/warped head, cracked intake are possible causes.
Water contaminated oil will be white and milky. Oil that is very thin and light coloured could be caused by fuel contamination.
Head gasket Cracked head
It will leak coolant just like it did before you installed a new gasket and you would have wasted time and money as you will have to take it apart again and replace not only the gasket but that cracked head.
Bad head gasket Cracked head Cracked block
Most likely a failed head gasket or a cracked or warped head. Less likely but possible is a crack in the block.
Head gasket or cracked head
cracked head or bad gasket
Cracked head or bad head gasket.
warped valve cover. bad gasket. cracked valve cover cracked block
Bad head gasket and/or cracked head.
most likely a blown head gasket, cracked head, or bad intake gasket. with the s series. i would venture to say blown head gasket.
