white crap in the oil

[Mista 2]

as the title says i have noticed some white foamy snot in my oil. i have just had a 20V black top put in my car and when i opens the filler car i noticed this. i dont know if it would be because the engine has been sitting around for a little while or not. i am just hoping it is not a result of coolant - oil interaction as i got the car back yesterday.

Thanks

Wherever it is, you've got water in the oil. The only way to find out for sure whether it's from sitting around or a leak is to change it and see if it comes back.

It doesn't often come from sitting around very often, but I've seen it come from washing the engine bay more than a few times.

Good luck!

well i can say they deffinately didn't wash the engine or bay so i guess thats a bad sign. do you know how much oil i should have for my engine? ohh one more thing i noticed was the oil looked a little over full, could this make a differance?

Thanks

my bet is it's coolant

[Sam1]

check your compression prob a bad headgasket?

I do some boat work in addition to my mr2 and absolutely, that sounds like water in the mix. Oil change and compression test are a good place to start.

good luck!

Mine too, but that's how we used to determine if it was a loose oil fill plug or a leaking oil seal when I fixed pressure washers.

The compression test would probably be a better way on an engine...

Betcha anything its coolant caused by a leaking headgasket. Sorry

White stuff in the oil is never good.

175 180 180 170 and from what i hear it is okay for a 4AGE. i dropped my oil and used some oil flush and it seems to be gone, yay. i guess it was just condensation from it sitting around. thanx for everyones help

Whoot, thats what im talking about! if i ever have an engine with questionable oil condition etc, new to me car, jdm engine, car sat voer winter for 5 months etc etc, i always run all the flush stuff, some times change oil back to back

[Mista 2]

well it ran castrol GTX2 as a str8 flush then castrol edge 5-30 for anout 100km then i flushed it with a nulon additive and again edge 5-30. it is going a lot better after that (i have other problems i am still sorting out though)

Good to hear... Good luck with the rest...

if theres a white residue on the oil filler cap then its definitly a head gasket ..

i noticed a small amount on my new 4age but thought it was there from before the rebuild .. but 14 miles later i was on the side of the road with smoke pouring out of the engine bay and coolant coming out of the exhuast ..

hope that helps a little .. i would do a compression test .. i did it and came up with some messed up #'s

[Mista 2]

its all been sorted m8, thanks for your interest anyway (look at post 9 for compression figures). no more white suff so i put it down to condensation or just the idiots putting the engine in stuffing something up.

aight .. sounds good .. wish i had that much luck with my two .. ahah .. but thats a long story .

Not true. That happens quite often on cars that aren't ran for long periods of a time.

[Adrians89MR2SC]

thats interesting .. ill remeber that next time i change a motor .. but its still a mystery why my head gasket popped .. probably was allready blown when i recieved the "rebuilt" motor ..
