Do you make a lot of short trips with it where the engine does not get up to operating temperature? If so, it could be moisture that has not burned off.

Does the exhaust have white "smoke"? If so, it may indicate a head gasket failure.

 

That is a good indication you have coolant in your oil. If you are lucky it's just a blown head gasket. If your luck runs like mine it's a busted block. Check your coolant level. If any is missing you may already know where it went. If there is no coolant in the reservoir, drain a little out of the radiator and see if it is contaminated.

 

thanks for the help

 

Is the oil on the dipstick this color?

 

 

 

The head gasket not only keeps the compression in the cylinders but it also keeps the coolant separate from the oil as the two circulate between the crankcase and the head.
If coolant is leaking from the water jacket into the oil passage your oil will look like a chocolate milkshake. You may also detect oil floating to the top of the radiator. If coolant
is leaking into one of the cylinders you will see white smoke coming out the exhaust. If oil is leaking into the cylinder you will see blue smoke coming from the exhaust. A
busted block will have the same symptoms but as long as you had good antifreeze in the engine when the temperature dropped you are probably looking at just a bad head
gasket. It's not cheap to fix but it's a lot cheaper than an engine rebuild. If this were my engine this is what I would do:

1. change the oil and filter.
2. perform a compression test

Standard compression on the 2.0 L is 199 psi. The minimum required is 170 psi. The maximum difference between any two cylinders is 15 psi. If it fails the compression test
you need a new head gasket. If it passes the compression test the gasket could still be leaking oil and coolant, but it could also mean an engine rebuild/replacement.

It looks like I have the correct forum so here goes :

I want to drain, flush then refill my 2000 J20 powered Tracker, I don't see a block drain plug and that's important to get all the old coolant and debris out of the water jacket .

Can anyone help with a picyue of the block drain plug location ? .

Failing that is there perhaps a lower coolant hose I can disconnect to drain it ? .

TIA,
