Stupid 1KZ heads the achilless heel sob sob

[cicak]

sob sob been through all this recently (and still fixing).

My GREENS 1KZ troubles recent Observations:
1. Low on power uphill
2. Cleaned and fixed injectors
3. New radiator 4 core installed 2 months ago and everything done including new coolant and hoses.
4. Drive this like a baby
5. grey Smoke on startup and ran rough if left for more than 4 hours smoked for months else it was running clean
6. Suddenly last week it started using coolant after never using any for 3+ years and the temp gauge started randomly rising and falling.
7. Checked the Waterpump and fine and thermostat also fine
8. Last resort was to pull the head as everything else had been done including pressure check

Here is the pic of the removed head they rung me to go look.

8 cracks in the head 2 in each cylinder all in the same placed circled for your benefit and education.

Told no second hand ones and they could not get one new engine required.

Purchased a new head yesterday (Toyota factory kit) for $3680rm ($1450NZD) I could have got one from OZ for $850 + freight - I knew where to look from some contacts

Now installing intercooler and EGT and new water temp gauge and a BOOST gauge.

Truck will be back in 3-4 days once the engineering shop reshims the valve clearances as the workshop cannot.

This may help anyone else with a 1KZ - my my I love the 13B-T in my other LJ77 its a much tougher engine.

Stupid head took the money I had been saving up for the twin lockers for the truck instead sob sob.

The new shiney head.

Thats pretty sh!tty man. sorry about your luck.

But now you have all brand new stuff and guages to monitor it all right?

Im just waiting for my 3B head to show its ugly. I had a hairline in two cylinders between the valves when I replaced the HG after turbo-ing. no coolant or overheating yet.... fingers crossed till next year.... turned the fuel down till then lol

It won't take much to achieve the breaking of the rest. Unfortunately , just make sure the wallet is padded sufficiently .

I still believe it was the rollover which caused this and the sudden loss of fluid from the ripped off all the radiator hoses and the sudden change in temp as it lay on its roof as it has not gone well since it had the new body put on it.

There is a another 1KZ donk sitting in the shop also with a CONROD BENT (no 1) but no other damage - I still believe the head will be up for trouble as a result as it is highly modified running no ECU etc and lotsa boost.
