Burning oil

[gtx ltd]

On my RXT 05, the oil is going low every time I use it, i use to to add 1/2 litre every time i use it and some times also a litre. Last time i used it, the low oil buzzer came on, and i add 2 1/2 litre.

I think that this is compretion in the bottom end.

Any help please?? Boat is stock

Do a leak down test and it will tell you if it is passing by the rings.

How many hours on it? If its burning that much oil it sounds like the oil control rings are shot.

85 hur.

What is down leak test? does it show in a compretion test?

Also the rear spark plug was different that the others.

Do a leakdown test. You pressure up the cylinders with a leak down tool and measure how fast it leaks down.

Can i check with compretion tester???

If it's as bad as it sounds you could do a compression check on all of the cylinders and it might point to the bad one, unless they are all bad. A leak down is the real way to check the rings though.

I pulled out the plugs, and the front and mid are nice and the same color, the rear is different and a bit darker. i will wait to jerry to give me the price of the tool, so i will buy it.
