03/05/2004 23:06:23   David   Okay, so I have two V4s and four engines (two uninstalled as i haven't yet got aroiund to creating a 2xV4-4WD (now there's a thought ....). Obviously the engine numbers were applied by Ford Cologne (as they were also used in a number of other cars) so they weren't necessarily fitted to Saab V4s in any sort of order. Can anyone throw any light on specs etc as I believe that the early engines (grey rocker covers) were different (had a semi-wet liner and weren't as "strong"??) from the later engines (black rocker covers). Here's what I've got:

74-model 95 fitted with engine ser no EY0143 M14 (V5 says 313014 and I'm fairly sure this is the original engine, as I have a fairly complete history for the car).

75-model 95 fitted with engine ser no 144125 (no other letter or numbers); not the original engine: V5 says EY291759 but this might not be the original number either.

Engine ser no EY2K26 - this the one with grey rocker covers, was fitted to a 74-model 95 in 1984 as a recon unit. No sign of the original engine (318099 stated on original invoice and V5). K26 is still a runner and was fitted when I bought the car last summer from its original owners.

Engine ser no (3C29) EY289540 - came as a spare when I collected the above car - seized solid but otherwise complete - may have come from one of their previous 96s. I have been stripping this engine (out of idle curiosity) and, apart from badly-seized rings it doesn't look too bad internally. May be worth rebuilding?

The numbering system confuses me - is there any sense to it? (does there need to be?). After all, an engine's an engine and could have had anything done to it during its life. I plan to fit the re-con engine to my long-term project 95 (the '75 one) and will consider rebuilding one or both of the other two engines (maybe with some mods!!). Does anyone know of or can recommended an engine specialist in the Bristol-Somerset area who has some knowledge of these engines? A web-search revealed very little about the Cologne-built V4. They're not complicated but I guess some of the bits are getting rarer to find (no point in doing a half-hearted job. Must talk to Martin at JamSaab as he's just stripped his Sonett II to convert it to RHD - the engine's shot and he'll be rebuilding it ... when I say "stripped" I mean "stripped!!!"

The Cologne V4 is basically a 4 cylinder version of the 2.8 V6 as fitted to Crapis and Granadas etc (NOT the Essex 3.0 V6). Many parts are interchangeable including bearings and valvetrain components.
I don't think it's too difficult to get all the bits you need to completely rebuild a V4, but you might have to do a bit of digging to find best prices.
As for engine nos. Ain't got a clue mate.  
04/05/2004 13:59:00   steve h   As has been metioned before in these pages, The old cars and parts shop' in Munich specialises in Cologne V4s. Try the link in the link page of this site. I rebuild mine with a 1700 crank from them and various modern parts from normal ford suppliers.
Engine numbers - Im with Senor Burt  
06/05/2004 10:41:20   Alistair   IIRC there were actually 4 engine "colours". Very early ones (66/67) were red block, silver rocker covers; next were black block/silver covers (67/69??); then blue block/black covers (69/73-ish) & finally all black. I think. This of course only helps if your engine hasn't been repainted!

The two early ones were the open deck engines, had the short-reach plugs, smaller rad, solex carb and I think semi- enclosed crankcase ventilation. Later ones had usual plugs & rad, Fomoco, harder valve springs (valve bounce at 6000 instead of 5500!).

I don't think any were more reliable or stronger than any others, though my dad always reckoned the solex engines were noticeably quicker than fomoco, even if you fitted a solex to the later engine.

I wouldn't worry too much about numbering schemes. I suspect that the 1500 used a different scheme to the 1200 (Taunus 12M) and the 1700, and maybe between engines destined for Ford/Saab. All numbering schemes changed during the life of the engine. Likewise, some of the recon suppliers like VEGE may well have "re-numbered" the blocks.

 
09/05/2004 10:36:19   David   Everything that's been said sounds logical - thanks peeps! The "recon" engine had the standard (long reach) plugs fitted to it when I got it and they didn't look damaged - I suppose the only way to identify everything correctly is to take one of the heads off. Previous VEGE engines that I've had (for Opels) have been painted blue - and,as I believe that VEGE is a Dutch company, it's unlikely that they'd stick a large red label on the engine giving running-in warnings in German! The numbering is unusual but it doesn't look as though someone has ground off the old numbers and re-stamped it. I've come to the conclusion that it doesn't really matter! If I discover anything else I'll post it.
