Right just done a compression test because I was loosing water. ! litre per 1-2 miles. In total put in more than 10 litres, which is enough to fill coolant system. No mayo in oil. No signs of oil in water. No water leaks at all. The other day though on tick over a lot of steam was coming from exhaust. Headgasket must have gone I thought. Problem is the results from compression test, which are as follows:

Cylinder 1: 150

Cylinder 2: 140

Cylinder 3: 144

Cylinder 4: 145

Cylinder 5: 146

Cylinder 6: 147

After taking the compression tester out of cylinder 6 there was a bit of oil around the thread, but all sparks plugs where fine when removed.

 

Any suggestions???

I’m puzzled (although it does not take much).

 

Thanks

Water pump bearing gone. Doesn't leak at standstill - well, not a lot, only leaks on the move. Can't explain the steam from the exhaust thougt - I'd agree with you about the head gasket...

 

Just a further thought that you might not want - cracked head. Opens when warm. Did you test the cylinders when cold?

 

Good luck

Have you had a look under the car to see where the leak is coming from ?. Obvisously you'll need the car running at the time. May give us more of an idea what it could be.

No compression test was done when warm. Are the figures a little low? Would putting new piston rings on improve the readings?

 

Thanks

the readings you have are within tolerance but that doesn't mean your gasket isnt leaking get a leak down test done or get a cooling pressure test done ! That is the easiest way to tell for sure instead of guessing or messing about. When your car is running and the radiator cap is off are there small bubbles in the coolant ?

Yeah checked under car while cold and while hot no water leaking. Even drove car, stopped and looked for water leaks on the road and where the car was parked.

Yeah when the car is warm/hot there are little bubbles in the coolant wen rad cap is off.

 

 

Does not loose water when cold and left stood.

do a cylinder leak down and go from there !

Thanks for the replys guys. :bow:
