When I got it home I checked the oil & found it to be way overfill & dirty. 2nd step I went to change the oil and when I drained the oil I found it was overfilled because it had about 2 litres of antifreeze in the bottom before oil came out. 3rd step I got the motor started and fit was not firing on cylinder #1, I poured tanny oil in the cylinders and let it set a few days. 4th step I started the motor , it smoked like crazy , I figured it must of had a stuck valve & blown head gasket, when I went to remove the head antifreeze leaked out the head bolts,I quickly put the bolts back in to prevent losing all my antifreeze I drained the block. When I took the head off ( didn't see anything wrong with the head gasket), turned over the motor and seen #1 exhaust valve not moving , I gently with a rubber hammer tapped the valve , now it works. 5th step Yesterday In order to see if the block was cracked (where I couldn't see ) I filled the water jacket full of water, checked this morning and the water was at the same level , put my finger in the water jacket hole and found when I pulled my finger out it was coated with oil. How would the oil get in the water jacket? the block does not have any oil in the crankcase, drain plug still not re-installed. Where did the oil come from ? no water leaked out. I hope I made this as clear as I could , if some-one could explain it would sure help.

When the engine is running the oil pressure > coolant pressure ,so the oil flows into the coolant jacket. When the engine is stopped, the oil pressure goes to zero and coolant jacket is still pressuized. The coolant then flows into the oil through the same crack. It is more common to have coolant in the oil than oil in the water, since the coolant molecule is smaller than the oil molecule and the collant passes through crack easier than the oil. Gas bubbles in the radiator as seen by removing the radiator cap is a result of a leaking head cover gasket, where the high pressure combustion gas passes through the ruptured gasket into the coolant jacket.

There by allowing the 2 to mix. [Reply]  [No Email]

IF what you consider oil is black as the ace of spades and sticky its combustion by products... I have never seen a water pump lube that would not mix with coolant... I have in the last few years seen bars leak that will not mix with modern coolant... [Reply]  [No Email]

Sometimes I'm my own worst analogist. Stan 9N 222933 2N with 8N motor 8N345567 8N 146710 8N 179555 8N 197904 8N 199000 8N 254079 8N 362039 [Reply]  [No Email]

Modern green anti-freeze already contains WPL. Unless you clean yer engine with special block cleaner, you will still have WPL in yer water jacket. It doesn't hurt to have old WPL floating around. As fer yer original question, BIG guess, you have a WARPED flathead and yer headgasket LEAKED anti-freeze into yer cylinders and down into yer oilpan. Yer lucky you didn't hydraulic LOCK yer piston and break a crankshaft. While you "might" be able to "skim" yer WARPED flathead (0.065" max), I doubt it. Yer better off byte the bullet and buying a NEW high-compression flathead which also will increase yer 2N's hp from 23hp to 26hp. As fer the SMOKE, using ATF or MMO (Marvel Mystery Oil) that is NORMAL to smoke all the oil off'n the CARBON that is caked/baked on top of the pistons. ........the amazed Dell [Reply]  [No Email]
