Title: 2.5 Flaminia engine not complete Post by: Richard Fridd on 04 February, 2024, 10:57:32 AM Another Flaminia short engine has materialised, mostly complete, minus sump, end covers and rocker covers.
As the motion parts were tight, I have removed the crankshaft to enable access to the pistons, three of which are now liberated following an overnight soak in Duck Oil. Camshaft removal could be problematic as the cam followers are not moving freely. There is an 'F' stamped on the block near to what looks like a casting mark. Quality control stamp? Crank good but number 2 big end shell bearing poor. Richard Title: Re: 2.5 Flaminia engine not complete Post by: Richard Fridd on 04 February, 2024, 11:21:57 AM F stamp. Looks like just the place for frost damage. Not ground back though, so an honest repair? Also an exhaust manifold with a push fit for the down pipe

The camshaft is out, but not before pushing out the followers to give the camshaft bearings sufficient clearance to allow withdrawal. Followers not so easy to access with the camshaft in situ.
Will have a closer look at what looks like a (repaired or not yet repaired) crack.

My parts book shows the both parts having flanges with three bolts and a copper gasket but it's a 1965 edition so maybe earlier engines were different.

On to the next job. I have heated the pistons in hot liquid which has enabled the stubborn second rings to be removed from their grooves, along with the oil rings which were free. Top rings need some more soaking. Fitting these rings into the bores indicate no excessive wear. Perhaps the cracked water jacket happened at low milage, which would have been disappointing. 'Lancia ' logo visible on a crown, which I haven't seen on other pistons, not that I have looked for such a logo. Title: Re: 2.5 Flaminia engine not complete Post by: frankxhv773t on 19 February, 2024, 09:20:27 AM I notice your manifold is marked 813.10 denoting the later 110bhp 2.5 rather than the earlier 102bhp engine. I've had a couple of these and some aspects, like the radiator hoses, are a per the 2.8 engine. I found this out when ordering silicon hoses from Dave Gee.
Title: Re: 2.5 Flaminia engine not complete Post by: Richard Fridd on 20 February, 2024, 07:14:18 AM Thanks Frank, I also have a water pump with this engine, which has a larger main casting than the one actually fitted to my own 2.5 PF Coupe. Only one exhaust manifold of the type pictured though.
