Just been doing a bit of work on a G13BB motor from a 1999 Jimny with the oil looking more like iced coffee

. Pulled the head off, all head bolts this time seemed to be under the right tension ie no loose ones. Headgasket, most likely the original was slightly deformed but no signs of breaks or cracks through it. Cylinders do not show any evidence of water/coolant entering them. Apart from the headgasket being on the soft side, there didnt seem any other significant obvious issues. So anyone else experienced this?
It did use quite a bit of water. What are the 13bb 16 valve heads like? Prone to cracking or any other issues. Where's a descent place to get the head checked in Briz preferable south side?
