Hi,
I am a complete newbie to the site and a good basic understanding of conventional non-turbo petrol engines and recently had an overheating problem on my 1993 KZN 130 1KZ-TE 3.0 diesel. My mechanic had changed all the fluids just a couple of months previously and said that the radiator had been really dirty but that he thought he had got everything out. The engine was not overheating at that time - or maybe I just never noticed it - but I took the car to him and he said the head gasket had gone. I do trust his work but didn't have the money to have him do the work so I decided to do the work myself. I took the precaution of removing and having the radiator checked - It was shot to bits after numerous radiator sealants had congealed over the years and globules of gunk the size of a small fist glooped out when I tilted it over. I had the radiator rebuilt with a new core. I have done probably 6 or so head removals over the years and was quite pleased with myself when it started first time with no apparent mechanical or cooling issues now. My problem is that I have been a complete idiot and not noted where any of the many vacuum hoses start and terminate and as a result the turbo (and probably some other bits) is not coming in. I feel a fool as since my brother-in-law has a 1994 4Runner also with a 3.0L turbo diesel I assumed that his engine bay configuration would be identical to mine. Alas, this is not the case and I have no idea where the VSV's(?) should be located and can only remember that the vacuum line (which I have since chased back to close to the brake master cylinder) runs parallel to and underneath the inlet manifold. I seem also to recall that it had two points of exit. I am totally lost and am in desparate need of help. Does anyone feel confident enough to offer advice? All the pictures, images and photographs I have seen do not have the same layout as mine or are in insufficient detail to be able to help.
