Do you know

[UP N OVER]

G'day there, would anybody know for what reason my 88in would have an exhaust manifold outlet that points up would & on about a 50 deg angle? I have not seen this before. I'll put a pic on soon, I'm thinking it maybe off a tractor:eek:

This is it,

It's probably an early 1958-60 S2 2.25L engine. .W.

It's a "swan-neck" manifold. Not a common sight, as it was only used on very early Series 2s (afaik). I think it was done so the exhaust was routed in the same fashion as the diesel's, out through the mudguard. On later petrols, the hole in the guard was fitted standard with a rivetted-on plate. Great to see one still around.

69 2A 88" pet4 (still in disguise), 68 2B FC pet6 (still resting quietly), plus 13 other project/parts cars (1xS2, 5xS2As, 7xS3s).

As indicated, these were fitted to 2.25 petrol, up to about 1960 (I have two of these engines here) I had always assumed the reason for the design was so the weight of the exhaust pipe was not taken on the studs, or to make these more accessible, or to give more room around the starter. Also simplifies the exhaust pipe routing. But I have always regarded it as a rather idiosyncratic design feature.

Thanks Boys:)

great for hanging a turbo off of on the 2.25 diesel.

From what i have sceen there were slso more prone to stress cracking hense why they were changed to the later type, alot of early vehicles had the later manifold fitted over time so the swan neck manifolds are quite un common.
