    Default ID19 motor with harmonic balancer

    I want to get rid of an ID19 motor that is complete and running. It too heavy to move house with. It is a late model 3 bearing motor with a harmonic balancer. Offers?

    Hi Darren,

    a couple of questions about the motor...

    I am restoring/doing up a 1973 DS Safari wagon with (I believe) the 1975cc motor in it (it has DX1 embossed on the side of the block). My motor is a bit tired - one compression down to about 70 pounds compression, and based on a 'wet' test lack of seal seems to be around the rings. Is the ID motor the same or a substitutable motor for mine? (Pardon my ignorance - I am new to Citroens, though a Pug owner for some years)

    Secondly, do you have any info about the condition of your motor, eg have you tested the compressions??

    Hi Chris,

    Darren's motor is a 3-bearing pre-1968 unit. Unfortunately not at all suitable for your Safari, which has the 5 main bearing motor. (I suppose you COULD make it fit - if you did not mind travelling a lot slower ).

    BTW - your engine should be a 2175 or 2347 cc unit - if it says DX1 on the block it is probably a 2175cc but in 1973 I would have expected all Safaris in Oz to have the bigger engines, but it could have been replaced. Unfortunately pistons and sleeves for 2175cc units are like hen's teeth - all those D Special owners upgrading! And you can't make the bigger bits fit the smaller block.

    AS per the previous advice from Steve Weddell, (previous previous owner) the car was fitted with a D Special drivetrain ie engine and gearbox. Steve had used the original 2175 engine and 5sp gbox in a car that he still has.

    Therefore you are looking at a D Special engine as far as I know.

    Craig,

    According to Reynolds anything with a DX on the block should be 2157cc or above - that does not mean someone might not have sleeved it back to 1985cc, or put a different block in it. In thirty years anything can happen!

    Just a suggestion, so flambe me if you wish. As the 2175cc motor has a 90mm bore, are there any alternative pistons that would suit in slightly bored liners, one that comes to mind is a 2 litre Ford Escort/Cortina piston with a 90.3mm bore. Or is it something that has been looked at and rejected in the past?

    Thanks for the info, guys. Looks as though what I have is a D special engine, 2175 most probably. Will pull the head and check the bore size before I go chasing piston and liner sets.

    On the question of using other pistons, JP Engineering Products [[email protected]] in SA will make sets of pistons for about $600 a set - I haven't had any made but understand the quality is good. So may be possible to get liners bored out to the next size up and get pistons made to suit?

    JP have some good stuff in the cast piston department... but I'd be a little bit careful with just one thing.

    They tend to use the same mould for several pistons, as you would. I am of the opinion (and who am I to know?) that sometimes when the gudgeon pin holes are bored into the bosses for them they don't allow enough material below the level of the gudgeon.

    If you ensured they worked from an original piston as their pattern you would have no problems.

    On the other hand, you might find other pistons that will do the job. Getting hold of a Repco piston book is the first step, then check the various features... bore, gudgeon diameter, crown height etc.

    You might find, for instance, that some Toyota piston at .030" oversize is a nice .010" oversize for a Citroen engine if you rebush the little end to a 1mm smaller size or something.
