I bought a VW turnkey engine from JCS and went on my trip to Arizona right after the engine was installed. Broke down due to engine failure and towed to a small local auto repair shop. Old guy tells me not a good idea to put long strenous miles on a new engine. He checks it out, tells me overheated probably because of a need for tuning adjustments required after a couple hundred miles or so. I call JCS and they tell me engine not covered under warranty for overheating and points out that recommended maintenance instructions are sent out with new engines. My mechanic who installed the engine never gave me that set of instruction. JCS pays for engine to be sent back to them, they repair it and charge me their cost of replacement parts ($295.00) and then send it back. Lost 5 days of my vacation but JCS stood by their product and delivered great customer service! I need a VW engine again I will certainly be back.

We purchased a turnkey engine from JCS. First road trip, less than 300 miles on engine we had to be towed home. They did pay to have engine shipped back, repaired it shipped it back to us. AGAIN, at 800 miles engine broke down again. We were on a road trip. Far from home we called JCS they said no warranty to bad and call ATK who built the engine. Who the hell is ATK? Well they were the "real" engine builer. We asked them the first time what was wrong with the engine the answer was we don't know. After our attorney told us to contact them. They then changed their story and said it was due to over reaving. IN A VW BUS??? HELLO? Terrible customer service, terrible product, bad quality and no help from them. Had to have our new JCS/ATK engine rebuilt at 1200 miles. It left us stranded and they did NOTHING. STAY AWAY. 1/9/09
