I need to replace the engine in my P38 Range Rover. Can anybody advise a good source for remanufactured engines. The existing engine has a cracked head. This is the second head to go and I'm not sure about the block, so believe that a replacement engine is best option.

look round for an engine out of a vauxhall omega,or a bmw 325/525.
 
Never heard of a block failure, heads usually fail due to overheating. For a second head to fail might just mean that it was a duff one if it was secondhand. Pressure testing does not always prove a head is good.
 
As mentioned, its much cheaper and easier to find an engine from a 325/525 TDS or 2.5 TDS Omega. Just make sure that it has an M51 engine code. I just paid £350 delivered for one from a 98 325 TDS with 98000 miles and a 90 day warranty. The cheapest I found one for the P38 was £850, which is still cheap compared to most (£1200 and up)

If you are having a garage do the engine swap, you will have to budget for an extra couple of hours labour cost, as many of the parts need to be swapped over. Also if you have an alloy inlet manifold, make sure the engine you buy does to, or if yours is plastic then make sure you get one that had a plastic one.

Just reading the comments above:
If your engine has a plastic manifold you can fit an engine with an Alloy manifold but you not be able to fit your plastic manifold to it you will have to leave the Alloy one on. (Studs are in a different place)

With respect to the FIP you will not be able to fit your Range Rover pump as it is a different size (Model number is different 994 or 995) What you will have to do is fit the EDC from the top of your pump to the to of the pump that comes with the Engine.

How do I know this:
I fitted an Engine from a '95 525 TDS to a 2001 DHSE last Christmas. It works and has done approx 10,000 miles
Any queries pm me.

Its a little less defined than that. The size of the FIP flange is a factor of the pump code yes. But many of the later TDS engines share the flange size with the RR. I would go so far as to say that any plastic manifold BMW engine will have the same flange size as the RR. A browse of BMW M51 on Wikipedia would lead me to guess that any of the 96 on engines will be an easy swap (sump only really), just make sure its out of a TDS and not a TD.

Your solution of swapping the top of the pump is of course correct.
 
Thanks guys for all the good information. As Datatek points out a pressure test does not always find all the faults on the replacement head. I have had this experience!!!!
I have located an engine and the swap is in progress. The case for a replacement engine verses replacement head is that the parts plus labour cost to replace the head .. (plus the risks with a faulty head) are approximately the same as a complete engine swop....yes I know the replacement engine needs to come from a good source!
 
Hi!

My engine got damaged due to a timing chain failure was thinking of replaceing it with a used one. As I assume all the componets to engine is working I'm only thinking of buying the block. Is there anything I should think of?

Mine has an alloy manifold, so was thinking of buying just a block with an alloy manifold.

Regards

I would think the cylinder head would be the most damaged with a chain fail.

you can you just have to redrill and tap new threads as I have done

Op try our sponsor or try bulldog trading he has a fewi can pm number if needed :)

The head on my 96 and 00 P38's have the holes drilled and threaded for both manifold types as standard.

We have had this out before , its probably had a head change at some time as mine was of a pre 1999 head and the studs for the plastic manifold had to be drilled so they do not come as standerd as somebody has already mentioned :)

That would be an head from an Omega then? All EGR Range rovers are fitted with a plastic manifold. It is not unreasonable to assume that Land rover received either or engines ready for EGR introduction. But the actual implementation was later than anticipated. As far as i am aware Omegas never had plastic manifolds. So on those engines there would be no need for a dual standard.
 
Stop assuming then !
