condensation in engine

[RandomTask]

just wondering, recently comming into winter, ive noticed alot more "mayonaise" in the oil cap, is it probable that its beacuse of the colder weather/moister air? or just coincidence and i have a blown head gasket(btw, havent noticed any other symptoms)

I'd be suspicious, I never have anything other than oil under the oil cap...

also its a 4k engine(carb'd), i usually get a wee bit, and i've heard most oldish engines do.

also theres no other symptoms of a blown headgasket, still runs just as well/fast, doesnt heat up any quicker, no water on the dipstick etc etc etc

i would seriously look further into that...

sometimes a blown head gasket wont allways show up all the symptoms, replace it anyway and see if it still does it

righto ya'll, replaced it, turns out the water had eroded a hole in the gasket so it went into the head where it should'nt have

anyway, it runs sweet now, doesnt seem to heat up as much etc, but the tappets are noisy which i guess is understandable seeing it took the push rods out etc

just one thing im concerned about... when i cranked it over using a ratchet on the crank pulley it made a hissing noise like a tyre being let down... is this normal?

thanks

normal.
Just tha compressed air in the cylinders exiting

for real bro, thats a relief, it appears ive done a succesful h/g replacement then


p.s yeah B_giB i see what you mean now, it wouldny have affected anything else but the water level
