D229 / TD229

MWM is an independent diesel maker, not a marque — and its D229 family is what South American Fords, Chevrolets and Volkswagens ran on for two decades.

⚑ That is why this page exists. A D229-4 in a Brazilian F-150 looks like a Ford engine and is not; searching MWM finds the service material, the parts and the rebuild specifications, and searching Ford finds none of it. The TD229-4 is the turbocharged version of the same engine.

These are heavy, slow-turning indirect-injection engines built for working vehicles, with individual cylinder heads on much of the family — so a head gasket failure affects one cylinder rather than the bank.

Everything is mechanical: an inline injection pump, no rail and nothing to read electronically. Compression, pump timing and injector condition are the whole diagnostic vocabulary.

They are long-lived and widely rebuilt, and in their home market the parts supply is still good — which is not true of the vehicles they came in.
