This is a service to provide aftermarket paid technical support that allows owners and mechanics to ask questions about their engines about concerns they are having. This is a 1 on 1 technical conversation held via email, service fee covers our time in discussing and performing remote diagnosis based on experience with these engines. The service will be tailored at diagnostic only and recommended repair parts only. The process of replacement of components and repairs is not covered, available via another service. Due to varying degrees of complexity in assisting remote diagnostics, pricing may vary depending on what is being diagnosed. If the system of the engine being diagnosed does not fit into the category choices, please contact us to guide what to choose or make an addition.

Note: Diagnostics can consist of parts replacement, listing contributing factors towards fault to physically check, and dialoging including picture and video reviewing. Parts to replace during diagnostic are required to be sourced from this site, substitutions are disallowed and will void current and future diagnostic eligibility.

Single System vs Multi System

Because symptoms with engine performance can be related to several systems on the engine, the multi-system selection is available. This allows remote support work through testing to identify symptoms caused by several contributors. Example: A non starting engine, this could be electrical, fuel system, or internal engine condition.

Diagnosis with a single system will be limited to tested components directly within that system subject.

Only complete engines produced and assembled by Peninsular or Unique Diesel, or rebuilt by Peninsular or Unique Diesel are eligible for this service. Self-assembled complete engines or engines assembled by another rebuilder are excluded from this service. The complexity of going through a problem likely resulting from incompatible components used or improper assembly or a combination of both is extreme and pricing on this product cannot account for this. In situations like this expect a custom service of around 1K USD to entertain such a situation.
