It looks like I have joined the list of victims.
I'd had some cooling issues as some may know, though never did the gauge get into the red. After replacing the radiator recently I had been keeping an eye on things.
I noticed after a recent trip the coolant expansion tank was low. I topped it up etc and gave every thing a good going over. No leaks found. Over a week of short trips the level dropped a further 6 - 10 mm. No sign of leakage. I pulled the plugs, they looked good.
Drove 120km to my mothers place on Friday. SI checked the level about an hour later. Expansion tank 50mm low, and the radiator down by about a litre. Oil starting to look coffee like and 10mm over full. engine still running sweet.
So, water in oil, oil in radiator. Given the history of these motors, I'm guessing cracked head. I'll find out later this week when the garage gets a chance to inspect.
Test drove a new car this morning. The Suzi has given sterling and faultless performance until this. I'll get her repaired and sell her. I needed more towing capacity anyway but I'd really have preferred to keep the GV for a few more years.
167K km btw.
An update.
The head is cracked, beyond repair.
Best price for a new head is A$2400.
All up its going to cost just over $6K to get back on the road.
To say I'm disappointed would be an understatement. 167K km and maintained as set out in the logbook. Never been overheated,(gauge in the red) though it has been above normal a few times. Pretty poor from Suzuki.
Another update.
After fitting a new head a pressure test revealed further leakage. The old head was that badly cracked it wasn't possible to test before the new head went on.
A crack has been found in the block, exactly where shown in the photos. LH side below and just in front of the oil filter. Impossible to see clearly because of location.
Some head photos.
Its cracked in several spots, between 2 and 3, mores on the exhaust side. Probably the hottest spot on the head. 2 you can see with the naked eye pretty easily.
