That may be the case, as the car was dropped off here after it developped a miss, the miss was 80% leakdown in one of the cylinders. I had never seen the car before with the exception of cruise ins.
My concern with cookie cutter engines is the lack of personnal attention that the bulk engine builders have with their customers.
I know everyone wants something lesser expensive, that is what drives companies like this to use inferior methods to engine assembly.
Studs, Cylinder Hone and Line Hone, washing and cleaning everything, Measureing all the bearing clearances all takes time, time is money, and if the money is significantly cheaper than someone else then that have skipped a step.
The motors that some of these companies are selling are no different then the stuff you can buy and screw together yourself, no machine work, no file fit rings, nothing. does that make it right, No.
My advice is if you need a engine, talk to your local engine builder, tell them what you want, and let them in on what you may know. They do not have to be a modular expert to figure it out, all engines work on very similar priciples.
The days of having to mod an oiling system to redirect oil and all kinds of other tricks are mostly gone (unless you are doing something really serious), The manufacturers have apllied all that stuff already.
Cheap is as cheap does.
