Buying advice

When choosing a valve train tool, consider the engine type you work on most (OHV vs OHC), whether you need on-car or off-car capability, and the spring tension. For frequent use, invest in a durable set like the Lisle or OTC. If budget is a concern, the Performance Tool or BGS options work for occasional jobs. Also consider a dedicated seal tool if you do many seal replacements.
