1984 Hilux 2.4 Turbo diesel cast iron head question

[Bradford]

This model year is a 1985... not '84.... don't think that minds much?

I have a friend that has a 2.4 turbo diesel 2LT Hilux with of course the old infamous cast iron head design. Does anyone or has anyone heard of a company or for that matter, anyone found an aluminum head design to change over with.... Cast iron heads as we know crack and the real way to fix them is hot pin them or if you are a master weld them... so an aluminum head would be the answer... THANKS TO ANYONE ... for answering this question... If no one does it.... perhaps I will start manufacturing them on my CNC machine from billet aluminum... just a thought..!!

Thanks for the chat back..... I am doing this forum basically for my friends sake... He is semi computer illiterate and as far as me.. I love my 300SD turbo diesel MBZ... but also really enjoy working on and learning about the Hilux... Do you understand about the rotary fuel injection pump on these things? My buddies won't start after it gets warm and he has to either let it cool down or pour cold water on the injection pump.. (strange).!! The pump was rebuilt and she runs great, but when hot or warm after some 15 minutes, won't start with the exception of noted water douche.. lol

1984 is non electronic pump?

So this makes no sense unless there is something wrong with the pump.

Try shutting it off hot and then crack one injector and have someone turn the engine over.. if its not pushing fuel out there is a problem with the pump..

At this point there is no other options for the head either a 2l head or a 3L head in cast.. You would think someone might come up with a better design as there are so many of these engines out their..

I thought the earlier 2L head design was better than the 2L-II. So the 1984 should be the older/preferred style of head. Or do they all suck?

I believe it is All Head Services in Australia that sells a beefed up head with an extra cooling port.

Turbo was the big killer not the head in the later models, same same...

Meaning I know it is not an electronic pump.... but still adding cold water on a rotary operated fuel injection pump to re-start the engine just doesn't make any sense... so am waiting for someone to tell me why it works this way!

I miss understood..

Did you try cracking the injectors after the engine is warmed up and see if fuel is being deliver?

This is a very basic engine like my 3B..

Some symptoms of poor starting when cold are due to low compression in one or more cylinders. But warm my 3B starts smooth all the time.?

Good luck

We found the problem it needed a new alternator anyways and on it comes the vacuum pump... Apparently the vacuum pump was defective and now it starts right up after being hot... "go figure"!!!!

Cool beanz.... was not sure of the shut down on that particular engine as it has been years since I worked on a non electronic engine..

So the issue was the vacume which is part of the shut down on these engines and or start up?

Yes it was.................

The power output goes down noticeably with a vacuum leak. A truck of that age will need all new hoses; you buy the stuff by the yard and cut to suit. Zip tie the ends if you want to.

First however, you need a compression test.
