Thread: Series Diesel Engines Sleeved or Not?

Lionel,
They are not sleeved. Turner Engineering are offering a way of saving a block that's been bored to the max by them boring & fitting sleeves to get it back to STD.

Parts are available to rebuild **itpart supply pistons and I'm sure Bearmach would as well. Plus there is the option of NOS if you are lucky. and an engine rebuilding company can often locate older parts through their network. Shell bearings are much the same.

200TDi's are more difficult to source parts for, 300TDi's are OK including replacement heads (haven't heard of any issue with replacement heads).

Another option is a s/h engine that someone else has removed to fit an alternative engine. An element of luck here as it's difficult to know the condition of the internals without stripping down.

nope cast block with holes drilled in it.

the sleeves are used when the bore goes oversized from damage (or even holed) but the crank journals are still in spec.

the bores are machined out to a larger size, the sleeve is then pressed in and finally remachined to take a stock piston size.

both the petrol and diesel engine respond well to having the liners pressed in and can be set up to take top hat or pinned liners if you choose.

the fitting process is an interference fit although I have heard tell of the liners being fitted by heating the block and freezing the liners. It works on small engines so in theory should work on the 2.25

and yes, parts are easily available for the 2.25 I've got 2 rebuilds on hand at the moment and am setting up for a diesel build in the near future.

Hello Colin,

Thanks for the information. In regards to 300tdi heads from what I have heard from a number of sources is that there is difficulty in getting replacement heads that are not warped. Also that even brand new replacements made as clones are frequently failing. FIgures worse than the Ancient Mariner - who at least ... "stoppeth one in three".

I have yet to explore the bowels of the engine. As you suggest, I do have a spare motor - however it is of unknown condition. I bought it off a bloke who was going to transplant it into another vehicle that had a petrol motor. Hopefully since it was going to be the donor for the project, it could be in good condition. I am not sure whether the previous owner actually ever had the motor running.

My hesitancy on starting on pulling down the smokey motor 2.25 litre diesel has been through taking the time to explore alternatives. Also to find out if parts on the 2.25 are still readily available. Which you and Dave have answered.

Now, I am waiting on one interstate source - who is proving to be very unreliable - to get back to me regarding an alternate motor. However, there is a family connection so one must be patient... apparently - sigh!

Kind regards
Lionel

Just to complete the information above - the 2.0l diesel fitted to Series 1&2 Diesels from 1957 to 1961 is in fact sleeved from the factory - with wet sleeves.

Very few of these engines will be found today, most were replaced by 2.25 engines by the 1970s, if not earlier.
