Gentlemen, thanks for all the advise etc.

Jules and Clem, I don't know exactly how I broke it. For the first two years of my ownership, I struggled badly with overheating, and also had an incorrectly-calibrated temperature sender installed. In the process I boiled the car several times, and even though this was solved a couple of years ago, I must believe that this was probably the root cause.

Now as several of you know, my job is designing pressure vessels. As a consequence, I have very little faith in stitch-weld repairs, and just slightly more in impregnation. However, of the mechanics I spoke to, all have had more bad than good experience with repaired heads.

As a consequence, I am not going to go down that path.

Alex, I have a lot of respect for the Lexus motor. But I still maintain that this engine is not an ideal fit in a Patrol (unless the low ratio is changed as well). But I believe that to do such a complex change will cost me more than my car is worth. As such, I don't want to go down that path, and even if I wanted to, I can't afford it.

Cedric, you won't believe that I actually gave very serious thought to that option. Although normally aspirated rather than turbo. But these engines are very scarce and also fairly expensive when you do find one.

The best price I have thus far been able to find for a new head is about R8550.00. Add to that probably another R4k for gaskets, rings and main bearings...

However, I have found a 4.5 engine, and am about to open negotiations.

I intend fitting the carburettor from my 4.2 onto this, has anybody tried this? Anybody know of any issues?

Thank you for the detailed post Peter. I hope you find the right solution.

Ek dink die carburettor van die 4.2 op die 4.5 gaan 'n baie goeie idee wees.

Hi Peter, jammer om van jou skade te hoor. In wes straat aan die onder kant is 'n engeneering plek wat heads reg maak. Kan net nie onthou wat is die plek se naam nie. Sal more na werk gou gaaan kyk. Sterkte met jou besluit wat jy gaan doen.

Hi Peter,

Sorry to hear of your troubles. I agree that repairing the head would not inspire confidence. When you are out deep in the gamadoolas the last thing you need is that nagging thought in the back of your mind that you are taking a chance because some aspect of your van is known not to be 100%. I love my 4.2D turbo, but your 4.5 idea also sounds like a good plan.

Good Luck, hope you are back up and running again soon.

Wat van Lexus endjun ?

Thanks gentlemen.

Oom Mac, as daar nie Nissan op die tappet cover staan nie, en daar het nie ander soos hy in Patrols uit die fabriek gery nie, sit ek hom nie in my Patrol nie. Ek weet in sekere opsigte is dit seker kortsigtig, maar dit is die enigste manier wat vir my sin maak vir 'n toer-voertuig.

As dit 'n dorpsjapie-jaagduiwel-karretjie of 'n quarriegat-speelding was, was dit 'n ander saak.

The only issues with putting the 4.5 in that I am aware of at this stage are getting the ignition to work, and that I will have to add an electronic fuel pump?

Ek sal nie gemaklik voel met die 4.2 se vergasser op die 4.5 nie, daar is net te veel mods wat gedoen moet word en sy venturis sal ook grooter gemaak moet word op n draaibank.
As die vergasser nie 100% reg verander is nie gaan hy by verskillende revs verskillend optree en dan kan hy dalk by verskillende revs lean hardloop wat dan weer die motor kan seermaak.
As jy die 4.5 roete wil gaan sal jy die oorspronklike computer saam moet kry, of dalk spitronics maar dit gaan seker nog R5000 extra wees.
Persoonlik sou ek net n nuwe head gekry het en klaar of as die res van die engine ook eintlik oorgedoen moet word sal ek dan eerder n diesel insit.
