The Triumph 2000/2500/2.5 Register Forum

We’ve been working on the car today and started checking the engine over. Whilst trying to identify the spec, we checked the engine number expecting to find the “ME*****” number shown on the log book and the Heritage Certificate, the stamp is what looks like a part number. Also some of the extraneous engine mounts seem to have been used at some point.

Can anyone help me to find an alternative location for the engine number, or identify the engine from the clues in the pictures?

'UKC' was a common part number for later (facelift) models.
UKC 0560 is a valid Triumph number for a short 2500 engine.
Looks like you have a factory reconditioned late 2500 engine block there!
From memory, when Unipart supplied parts to BL, they were often known as 'Goldseal' replacement engines, immediately identifiable with the horrible gold coloured finish that they came in.

OK that’s good news then. Is there anyway of checking the block to confirm whether it’s a 2.0 or 2.5, short of taking the head off and measuring the bores? It was sold to us a 2.0.

The block is black and no sign of any old gold paint.

A 2500 has a deeper oil sump, I’ll check the dimension tomorrow for you.

I think I may have mislead you there - many BL replacement engines, such as for the Mini, Marina etc etc and similar BL models were fitted with 'Goldseal' engines as replacements, but I have never seen a Triumph Goldseal engine (if they did them?).
The listing in the Triumph parts book for models from 1974 on for UKC 0560 is definitely for a 2500 replacement block, so its very unlikely that it has become a 2000 in capacity. Unless its for originality reasons, most people would replace a 2000 with a 2500 anyway for the extra performance, not the other way round, as the late 2000 with domed top pistons were a bit lethargic to say the least.
I would check the stamped number on the cylinder head which should give further info - if it's 219016 it's definitely going to be a 2500.

As John says above also the 2500 has a double timing chain so the cover is deeper. As I went measure the oil sump it would be easier to dimension this.

Thanks guys, I’ll let you know what I find out.

I shall probably pop the head off and camshaft out when the weather is warmer, to check them over for wear. The top end sounds a bit rattly it could be rocker wear or timing chain - time will tell.

And 219015 is for a 2000.

CW has a very useful document of Head Applications with casting and part numbers listed together with which engine they were used on. However, it's a PDF and they aren't allowed on the forum! (OK as administrator I should know to change that - but I don't).

Look in Chris's Technical section.

Cheers,
Mike.

Yes I have seen CW’s very helpful Tech Section

Unfortunately I found the head casting number but not the stamped number

The casting number is 313248

If the stamped number is 219015 - CW’s table shows it as used on 2.0 and 2.5 cars

Don't forget, the very last PI's with cylinder numbers 219015 were replaced by the S in 1975 with heads marked 219016. Apparantly the 219016 heads are quite desirable due to their better 'flow' characteristics.
The stamped number can be found to the right of the casting number, on a flat piece at the front of the head between the first and second cylinder head studs as viewed from the manifold side (the front of the engine is always no 1). It is adjacent to where the edge of the rocker cover sits.
