Coolant in Engine Oil???
Hoping you Mopar guys (or anybody) can help with my problem. I have a 1969 340 small block dodge motor losing coolant into the engine oil. It seems to be a slow leak as it takes a few weeks to notice water in the oil. I have replaced all seals and gaskets in the top half of the motor, and used thread sealer where head and water pump bolts go through water jacket. I tightened all bolts down to spec, and used rtv sealer where needed. I thought it was fixed but this weekend I checked the oil and appears to again have water in it. Could a leaking timing cover gasket be letting coolant drain into the oil pan or could the aluminum cover itself be cracked on the inside and letting coolant into the timing chain area and then down into the oil pan. I have read about the last part being the culprit in a similar situation. I hope you guys can help as I am getting very angry about not getting to the root of this problem.

The most common culprit is the intake gasket or timing cover gasket. Intake gasket killed the 318 in my '51 pick-up (which gave me an excuse to build a wicked 360 for it [sm=crossbonesgif.gif])

i do NOT like rtv sealers. i like permatex #2. rtv acts like a luberacant and lets things move around. and #2 works everywhere, even threads. in alunamiun, and spark plugs use anti-sieze compound, and be careful of tourq,spec. pardon my spelling

I am guessing cracked head. Run engine warm, if water is coming out of your exhuast pipe, possible cracked head or block. Check spargplugs for rust spots/water, note which cylinders are different colour. I usecardboard with a rough drawing off engine layout and an arrow pointing to front of engine. Bung 6 or 8 etc holes in cardboardwhere cylinders would be tomatch any duff plugs to cylinder.
