Hello there everybody & happy new year.

I hope someone out there know the answer to this. Any help would be gratefully appreciated :-)

Are there any differences between series 1&2 1600 blocks? I would have thought not, but I have seen for sale a block that is for a Fanalone and the same person has a s2 engine for sale as well and it started me wondering. I thought that the block for s1 & s2 would be the same, 818.540.

If anybody knows if there are any differences I would gratefully like some help.

Thanks in advance

I have both sets of TAVs and they say !!

They have different part numbers:
S1:1109111
S2:1109447

and the S2 has what looks like an extra block to sump fixing screw in the timing chain chamber (item 18 is not present in the S1 TAV).
Edited - I have checked this and the bolt is also there on the S1, just not shown in the TAV

I think the S2 had a different alternator on -whether that makes a difference I don't know. If you can wait I can check at the weekend when I can compare my engine (S1) with my brothers (S2).

I would expect it to be different as a series 1 would have had a dynamo, whereas series 2 had an alternator & the mounting points are different.

The S1 1.6 had an alternator (I think only all others had dynamos ?) - whether it is the same as an S2 I don't know, but will have a check  Undecided

Brian,

Sorry to correct you, but the 1st series 1600 had an alternator fitted from the start, but I believe the S1 & S2 1600 blocks are slightly different - in that the alternator mountings differ along with one or to minor other differences.

Hi Chris,
I don't mind being corrected, I bow to your greater knowledge,  Grin what I meant to say was, if it was the same as for the smaller engines Embarrassed

The S1 block has 2 cast in alternator mounts 60mm apart (face to face). The S2 block only has one cast in mount, the second is a plate mounted  by bolts on the front face with a distence of 65mm. It may be possible to mount an S1 alternator on this arrangement by use of spacers, or use an S2 alternator (I don't know if the wiring/regulator would need changing or if the belt drive line up is the same). Hope this helps - maybe someone else can add something ?

Hi Neil Thanks very much for the reply

It seems I have a split block, so that coolant transgresses into the combustion chamber and mixes with the oil. Probably caused by the coolant freezing one very cold winter  Is there a fix for this - like a sleeve or welding?

Can anyone help or give advice on this

Thanks very much

Cracks can be repaired (depending on the severity and location). The preferred method is known as "lock and stich", where small holes are drilled through the crack and then small fine pitched screw threads are inserted which then pull the crack together.

For an example see here

Indeed my brothers engine had a cracked block and my father repaired it using this method and it has since done 30+k miles with no problem.

There are quite a few specialist around, a quick search should find one convienient to speak to.
