Thread: 1955 86" engine dilemmas

I'd go for option 4. SOmebody will be along shortly no doubt to tell you how to do it ,or whether you can or not. I like the original engine. I have seen a couple of old diesels on eBay/ gumtree. HOw about putting an ad in the wanted sections.cheers ,

The other option is to get a 200TDI out of a Disco, leave the turbo off and it bolts right up to the series gearbox.
I put one in an 80" and are currently putting another in a 88"
Google 200 TDI into series Land Rover. Lots of info.

Here is a good option,

Series I motors are either 1.6L (48-53?) or 2.0L (54 - 58)
This engine would be ideal and it is in sydney!


Cheers

I have been facing the same dilemma recently regarding my 80". The engine (Holden 186) is actually pretty clean and strong, but my gearbox (also non-original) is hopeless. The clutch has now also given up, forcing the issue!
Since the gearbox needs to be pulled out anyway I figure I may as well return the motor to LR, so for me, Im likely going for something like your option 2 (replace with 2.25 petrol), although I don't think I have any chassis issues so should be straightforward. FYI Im not an expert but im told if you use a s2/3 engine you should also use a corresponding gearbox.
If you are interested in a diesel, check out the markets, there is a complete LWB diesel for sale that may be a viable donor.


PS I suggest you also contact AOMC. My landy is from Victoria, and despite being currently fully registered, it did not show up on the Vicroads online search tool (chassis, engine or rego number). I think this is because the rego has been continuous for 60 years, so predated Vicroads records- and all the old stuff is now held by AOMC. I contacted them and they ran a search (you need to provide the engine number, and there is a small fee). This should tell you whether it has been registered in Vic previously with that engine. If it has been you should hopefully not need an engineering certificate as back in the day a Holden conversion was an acceptable alteration. If you google hard enough, somewhere on the internet is a scan from an old standards manual confirming this..

Finally- finding the date of the conversion may bear some relevance for your decision. In my case, I found out the engine was changed in 1975- meaning the Holden motor has in fact been in there for 41 years, and the original 2L only lasted 22 years. An interesting quirk that my Holden motor is more historically relevant to my car than the motor it was sold with!


Ultimately it comes down to personal preferences and circumstances- I want to return my car to a landy engine, and that was the deciding factor.


I hope that helps!

Thanks for the replies everyone! I'll look into the 200tdi option and also I will certainly be in contact with AOMC - if the landy has been registered with the 186, that would be great news (for my wallet at least...). Deciding on the engine is tough - there are so many options!

May I ask if this is the same for a 300TDI engine ?

My 55 86" has a 2.25 petrol in it, prolly first installed back when it was a working vehicle, why not go this way, the 2.25 petrol is a quiet smooth (in relative terms) reliable easy to work on engine. It also opens up options for finding an engine, as in upto a Series III.

The Discovery 200tdi motor is the only one that will fit onto the series chassis engine mounts with no alteration. Ideally need to fit defender manifold / turbo as it sits higher than the disco one and won't foul on chassis. Also makes the exhaust system easier I'm told. It will also fit series gearbox with little alteration.
The defender 300 tdi motor will foul on the chassis mounts and uses different engine mounts. Fabrication will be needed. I think the 300tdi discovery motor has similar issues.

Hope this helps
