Just found these gems on my backup drive. Short story :

As 2 injectors were on its way out , the van randomly stopped. Looked around for the options , new injectors  £350 each(ouch).Not to mention expect the other two going soon. So to be on the safe side 4x multiplier, re-manufactured £250, e-flea market £150 each but there was a twist. I have found a complete engine with only 65.000 miles on the clock from another seller.Bought immediately!

This has happened two years ago. And it is still in daily use! Question is why Japanese? Because as far is know the engine is an ISUZU. Which is an excellent workhorse.
