Is there any one here with experience with Reviva remanufactured engines? I recently purchased a 2003 Blue Bird (28’) with the T444E, that has a Reviva (201
engine and wonder if it is more than a rattle can rebuild. I contacted the company to try and find out more info on this specific engine, like any modifications such as cylinder bore size or whether the injectors were replaced. They didn’t have any of that information other than it was based on original engine specs. The warranty dept said that this was the second engine they delivered due to the first being returned for a warranty exchange. Makes me wonder about their quality control.
The engine seems to run just fine but it does have some blow-by from the valve cover vent. Not really bad but has some slightly visible smoke and only if you get down under to look at the hose end. The tube that runs down was sitting on the front axle pointing to the front of the bus. There was significant oil residue in the front driver’s side of the engine area including a build up on the outside portion of the intercooler. I am assuming due the vapors made it to the outside of the bus only to be sucked back by the fan. This is a HC bus and I think it did a lot of idling.
