I have used them several times before on Subaru and Audi products, so I had them rebuild my boat engine, my parents moved so I put the engine in after the warranty expired the following summer, the pt a timing chain on that rubbed against the timing cover housing. went in replaced it, then the engine had very low vacuum after hours of diagnostics and them telling me it was a timing concern, they had put in the wrong camshaft.
