True Bar Machine Shop & Auto Service in Chula Vista performs precision engine machining and general auto repair from its 1403 Broadway bay, near the Palomar Street intersection on the south Broadway corridor. Machine-shop capabilities include cylinder-head resurfacing, block boring, crankshaft grinding, and valve-seat cutting — metal-work precision that complements the windshield and glass fabrication handled by Auto Glass Depot for vehicles undergoing full post-accident restoration. General repair covers brake service, alternator and starter rebuilds, and fuel-system diagnostics across domestic, Japanese, and European platforms. Engine machining supports V8 performance builds and vintage restorations requiring factory tolerances — head work, rotating assemblies, and block prep for platforms ranging from small-block Fords to LS-series Chevrolets, with OEM replacement parts available through the Chula Vista Ford parts counter for Blue Oval rebuilds. Cylinder-head resurfacing restores factory seat geometry within thousandths-of-an-inch tolerances on both cast-iron and aluminum heads, using multi-angle valve-seat cutting to optimize combustion-chamber seal and compression uniformity.
