2.8 spun crank

[patrol2.8]

Kinda stuffed the crank what are your thoughts should i
A: Just get the crank replaced and keep the 2.8 there is nothing else wrong with the motor
B: 4.2 conversion
C: Ls1 conversion

[threedogs]

would really depends on funds available.
Were you happy with the performance of that motor??

[patrol2.8]

three dogs ive never had any issues with the 2.8 motor yes its sluggish and can struggle with the camper going up hills but you just drive within the capabilities of what you have having said that the engine is modified and most people ive been 4wding with that didnt know the car couldnt believe it was a 2.8 till the bonnet went up but i drove a mates 4.2 and another mates who has done the ls1 converstion and have to say the power of the ls1 impressed me but im old fashioned and cant shake the notion that 4wds should be diesels my young bloke is just finishing off his Ls1 converstion and keeps telling me thats the way to go just so confused guess i will do the ring around Monday get some prices and see where i stand from there

You could also get your crank repaired. It looks as though it's only the balancer section that's stuffed which is lucky cos if the timing gear section had let go it could have been messy.

Cheapest option will be repair/replace crank. As you will have it apart I would chuck some new bearings in at least.

yes its only the balancer section thats gone the rest is fine just need to find some where in Melb that can do it also thinking now that its off the road might be time to remove the intake and get rid of all the gunk

Looking from this angle looks like a new crank

what side of town ore you on,?
depending on what you want to do if you want to do a lap I would suggest diesel.
If you only use it for weekends away and shorter trips under 1000 K then the ls1 may suit you better
I'm sort of going through the same dilemma even though there is nothing wrong with my motor ATM.
I also want to convert mine into a dual cab but thats another story.
TD 4.2 would be nice as the value will go up I think or at least hold a decent price

A TD42 coversion from RD28 will also include a gearbox and transfer case as well. Yours is one of a number of RD28s that have the same damage. I have had a look for threads with info on successful repairs, but came up with nothing. I think someone had their stripped keyway welded.

I know gear box needs to be changed but i thought the transfer cases were all interchangeable

Hopefully you are correct.

So now a TD24 would be nice?

The other day you were against it mentioning they were slow and thirsty and the ls1 was the go. Which one is it?....

Been a while i finally went with an L76 with the 6 spd auto engine out of a Ve ss.The engine should be in this weekend so hopefully have her back on the road within a couple of weeks figured the amount of trouble i had with trying to find a mechanic to fix the old 2.8 and the availability and the relative cheapness of the ls motors had nothing to lose based on on research and a guy i know who can tune the ls motors their claiming they can get 14 lt per 100ks out of it but we will see

Nice mate. In a way a good outcome.
Let us know how you go with those fuel figures.

Had the same problem just recently, common with Rd28Ts woodruff key lets go. engine still performing well like yours after a lot of research including replace engine the cheapest option was to strip down the engine have the crank titanium welded ,Why did i not just buy another second hand crank, ? because their like finding gold teeth in a chook, [though you might be luckier,] a new Nissan crank is worth an arm and 2 legs. you will probably need a new harmonic balancer of course, & if you decide to go this way replace your big end & main bearings as well. I also had it balanced, that has improved the power and fuel economy significantly, worth the extra $$ Replaced all the necessary oil seals & other bits & pieces too. Everything $ wise came in well under a second hand or new engine. Good luck mate Rob Ness
