It is my understanding the the SP 135 has corrected those potential problems.

There are a number of "updates" on the 135's vs the 120's. Injector pump oil circulated from the engine oil, improved head bolt and head gasket design, improved water pump shaft design, stainless steel exhaust water injection elbow, automatic closed cooling air bleed setup to name some. I have 2 with about 4800 hrs on them and they run extremely well.
