Engine cc size

[Steven139]

Hi I've got a spare engine block for my car but I don't know if it's a 1400cc or a 1600cc! How do I measure the size of the bores to find out what size it is?

If the head is off you can use a bore gauge or a vernier calliper. If the head is on then its a bit more of a challenge. I suppose you could burette a cylinder at TDC and another at BDC using paraffin via the plug holes, take the difference and multiply by the number of cylinders, make sure you clean out the cylinders after very thoroughly.

Bores!

You'll need the stroke length as well. Normal ruler will get you near enough. 100% accuracy then you need verniers, internal micrometer etc.

Got the engine number? You can probably look it up that way, depending what engine it is.

Catching them first is the hardest bit.

It might prove to be a pig of a job

Presumably this block has an engine number plate, or some marking on it?

[Steven139]

Can't see any markings on it! Looks like they've been removed

I've never seen a block that didn't have a casting number embossed into it.

And certainly anything with the engine number AWOL raises eyebrows.

Oh actually yes I have. The Peugeot XU engine used the same block for 1600cc and 1900cc variants but it was only the crank rods and pistons that changed. However there was always a metal tag rivetted on with an engine code.

If the stroke differs between the engine sizes a knitting needle or similar stuck down the plug hole with the piston at the top and bottom of the stroke will show you the stroke length.

Obviously doesn't help you with the question about bore size though.

Dropping the sump would give you access to measure the bore and stroke. Perhaps you will want to do this anyway to find out what state the bottom end is in before fitting it.
