Not sure how to do a compression test, so haven't done that. The oil smelled funny when I replaced it, but I didn't notice any water. The coolant was empty, I filled it with distilled water since I wasn't sure if it had a leak. Last time I checked, it's still full but maybe just because I haven't been able to drive it anywhere. It used to disappear when the car was alive, but maybe it just evaporated? I never put in antifreeze or special coolants, just distilled water.

I'll have to double-check that everything is plugged into the instrument cluster and watch the oil pressure gauge.

The funky Toyota turbo came with the car when I bought it in 2008 and it seemed to work before I gave the car away. How does the oil feed work? I've only messed with the breather hose. I've included a photo of the turbo with air filter hose removed...is this the hole I should squirt the WD40 into?

Yes!! Just spray it in while cranking.

Cracking the injector nuts is needed to get the air out of the high pressure side of the system. If you have air in the hard lines, it will be trapped between the delivery valve and the injector nozzle. The trapped air acts like a cushion and the injector nozzle can't pop until you let the air out.

question?? if i didn't crack the injector nuts would that be reason for my valve cover breather hose to be leaking??

No, there is no need to crack the injector nut anyway, and it doesn't cause breather hose leaking.

No. However, if you have air in the injector hard lines, cracking the nuts at the injector is the only way to get it out.

Not true.

Started the car Friday evening, cranked it with wide open throttle a few times until it gave, no WD40 required! Did a proper diesel purge, never heard the engine run more smoothly in all its life.

Good News! Glad it got sorted out for you!
