The engine for my Stratos project is finally in bits and has been checked over before the rebuild. Overall it's in amazing condition considering the mileage.
You can still see the honing marks on the bores!!
Crank and camshafts all fine too, no scoring or wear.
One of the heads is a darker colour (inside) than the other. Engine builder not sure why and never seen mismatching colours on twin head engine but perhaps one was replaced at some point?
One small issue. Whoever did work on the engine before (we think maybe the rocker covers and / or sump have been off before) used a *bit* too much sealant and the surplus found its way into the sump. About 70% of the pickup area of the pump was covered!
So - these engines seem very very strong and well made.
The guy building my engine then called a mate of his that builds Alfa race engnies and had a chat. He said the liners and pistons would be good for another 170k as they never wear out. So we've got a list of things we are thinking of replacing. On the list are a few things that seem like a good idea but when you add up the costs they get mad expensive - bloody 24 valves.
I'm only going to do this once and (like me) the engine builder is a stickler for doing stuff right and he's suggested changing just about everything. So this is a list above and beyond what I would have expected:
Valves - why not re-lap them? £360 a set
Valve springs - I can't seem to find a source for these - can anyone point me in the right direction?
Valve guides - £115 happy to change these.
Cam followers - £245 - worth changing?
Also want to replace the oil pump - where can I get one and what do they cost? Can't find anything online.
I'm going to have it balanced and also fit ITBs. Does anyone now if you can fit Jenvey's ETA2 electronic actuator to the Alfa V6 - is there room?
Cheers for any advice and info anyone can supply.
