hello

 

my 79 1275cc mini ,
just finished very extensive service,
unfortunately there is a massive oil leak,
the other thing which i am worry about
after few miles i stopped for gas
a burst of coolent fluid got out (it seems to be from the overflow pipe )
what could have caused this kind of problem ?
 
 
thank you

How far full did you fill the rad? Above the fins or to the top of the tank? If its overfilled, expansion when parked after a run will push the excess out of the overflow, happend to me a few weeks ago after a hard drive.

fill rad about 1/2" below the ring where the cap seals

as i dont have any expansion tank .

Check the level again and it should be probably 1/2 an inch over the top of the gills as a minimum

 

if its less than that you may have a problem.

 

but It could just be purging air out of the system as it all settles down

 

top it up again (maybe a little less than before) and keep an eye on the engine temp and coolant level.

 

It may also be a rad cap issue...too short or weak

Happened to me yesterday.

Always carry water to top up, just in case.

I found out my problem was a split in the bypass hose. This is rather annoying as it was a Minispares black Kevlar one that was only 3 years and 4000 miles old.
