I did a static compression test on the weekend and came up with the following results.

CYL 1 100psi

CYL 2 100psi

CYL 3 100psi

CYL 4 100psi but leaked to 0 psi in 1min 40 sec

CYL 5 100psi but leaked to 0 psi in 30 sec

CYL 6 would not hold above 60psi unter cranking.

what gets me the eng runs smooth and is still making decent power. It goes to the tuners on tuesday as i have fitted a bigger turbo. Just wondering what people think of the results.

I spoke to the tuner about my results, and after having it on the dyno he believe the valve steam seals might not be sealing properly. Reason behind this was smoke on back off, even tho all old oil should be out of the intake system (due to blown turbo). The car made 165rwkw at 12psi, with a boost controller that was not holding boost at the desired level, 14psi. (it top 16psi and bleed of to 12 psi). We will be investergating further.

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
