Hi, Looking at buying a ute with a r2 mazda 2.2 diesel engine. Has hairline split below rocker cover on head, perhaps on an oil gallery, as it has fired a fair bit of oil over things. Question, can it be repaired in situ, or new head? Engine was rebuilt a few thousand kays ago supposedly

If it was rebuilt a few thousand kms ago, why are they unloading it now, surely you would want to get your moneys worth after a rebuild., Run ,those R2 are shockers for problems.

Just walk the other way, everyone offloads these because they are sick of throwing money at them. Its surprising that anyone has even bothered to recon one, assuming they did it properly, its hard to get machine shops to touch them.

Point taken franc, it seems some had the perkins derived 2.2 and others the mazda r2? anyhow uncle google seems to have a plethora of information on just how much they seem to be turds

Yes it was, Mazda referred to it as the S2, not the R2. but it was not used after 1985. A solid and reliable, but not powerful motor. The R2 replaced it and it was more powerful and free revving but in almost every other way it was an engineering cockup, the main problem being it was a modified petrol engine. Cracked heads, broken rings and cracked cylinder liners were just three of its nasty habits. If that wasn't enough they went on to make a smaller version, supercharged it and used it in Bongo vans and Capellas, and the Jap market Ford equivalents, the Spectron and Telstar. That was double Don't Go There stuff.

Quite possibly the worst diesel engine ever. Bongo Brawny vans used that engine.

If your looking at buying this ute,then factor in to the price that this engine is a total piece of crap. gutless. noisey. the-
placard says change the belt every 100thou. nar it means change the head every 100thou.

[I had one as a company ute a few years back]
