I was cleaning out the shop
(see the 'for sale section)

and took a few pictures of the US Marine G54b parts:


if you ever needed to watercool your exhaust, I guess...


Maybe make your Monty engine into a stationary generator?


and a complete no- name 2-bbl carb. It's a nice manifold, but it's not the ubiquitous Weber bolt pattern.

Strange stuff, eh?

Toby

Is it the heater core? it goes around the exhaust just like the old VW bugs.

Where did you get that stuff?

No, it's a jacketed marine exhaust manifold - cooling water runs through it. From the rusty appearance I'd guess it to be a raw water cooled engine (cooling water is drawn through the hull, circulated through the engine and out the exhaust) as opposed to a freshwater (closed/recirculating/heat exchanger) system.

It showed up on a pallet of 2 engines from a local salvage place. The motors had been sitting outside- I rebuilt the better of the two, and still have the rustier.

They had US Marine stickers on the blocks, non- jet manually- adjusted heads, and the rear adaptor on one. Same cam as the Montero, and clean oil!

One had a 'test' tag on it indicating that it had 20- something hours on it- and the inside looked like it. Timing chains, bearings, cams, etc all looked new. Sadly, with the block damage, I had to change the pistons and rings- but then put 75,000 on the thing, and sold it to a friend who's still driving it.

Frank, they had heat exchangers and purge tanks for the engine water jackets, so I really can't explain the rust. Unless the manifold got seawater and the engine got coolant?

Toby

Probably not - actually, the rust I'm seeing on the outside is normal around salt air, spray and ocean bilge water. The inside of the jacket doesn't look too bad - maybe mostly scale.

One thing I'm glad I don't have to ever do again is boil out a raw water manifold in acid..... nasty process. <img src="/forums/images/graemlins/baby.gif" alt="" />

Did it have the same bellhousing bolt dimensions as the later 2.6's? Leads me to thoughts of a divorced tranny....

I dunno...
it looks a bit generic in its flange pattern, now that I think about it.
But it came off a G54b...
