Offroad-Express

a small problem developed with the mighty 21psi boosted 13B-T powered LC II.



Only one piston ruined more pics later and the rest of the damage as we still ascertaining what actually went wrong.

Sorry Ant's kinda ruined the next few weeks offroading with RED at present better stay in KIWI land until its fixed hahaha.

jebuss christ!

Well if your gonna fark it you may as well fark it properly!!

That's a good effort

Pistons, Rings and Liners ordered from SABAH Arrive monday or tuesday.

Looks like it was a squirter failure from the discussion with another mechanic proably the squirter broke off.

I hope to have it rebuilt and back on the road in two weeks along with a host of gauges fitted this time.

Picks of the damage.



The clutch needs to be replaced 100,000K and the GOD winch and the excessive power has taken its toll.

dropped into the rawang hospital yesterday to pickup the 75 series air filter to take to the Volvo when I realised the doctor was working on my engine.

He said start taking pics.

The old remaining pistons some small signed of oil being a little hot at some stage.







Then the issue the bearing shells for the crank despite them being standard will not let the crank rotate. We untorqued it redo it and just tap the bearings down only two and then it will not turn again. Inspection of the shells shows they slightly different shape to old ones despite them both being STD and different brands sigh.

Damn

Rebuild will continue this week then the gearbox rebuild will start when the engine is started.

Finally all finished rebuilt the 13B-T and the gearbix new syncro's and and new bearings and a new shaft one was a little worn.

Got RED back last Tuesday it arrived at work in the tow truck and I put Blue (1KZ) on the tow truck to get new BRAKES and new trailing arm bushes. The newly rebuilt 13B-T ready I was told to drive it carefully and test it out do not go over 2100rpm and check the noise.

Red was not happy it started tapping noise at 2000rpm. THis morning (Saturday) took out to the workshop and we fixed the Blue 1KZ nightmare up after the Quiet Sungai Mas trail trip last weekend.
1. New trailing arm bushes
2. New leading arm bushes and castor correction also
3. Straightned steering arm
4. Drained DIFFS (yes they had water in them) and refilled
5. CHanged SUMP (took me 2+ hours to change) as the 1KZ engine in BLUE was from a HIACE and the front PROP shaft had given it more than a FEW WHACKS almost through the sump the damage was quite bad. BE warned anyone who puts in a HIACE 1KZ change the sump or remove the front PROP shaft LOL.
6. Refilled and ready to rock again.
7. After lunch started stripping REDs 13B-T down slowly stripped around the head and finally lifted it. BINGO we could see the noise reason. YEs the valves had touched the pistons on pistons 1 and 4 mainly. WE measured the head gasket and the old one was 1.65mm and the new one was 1.35mm. Monday we will know what we can buy here to provide a solution.
