WAM rebuilt a 390 for my 1970 F250. I started driving it in late October 2016. The engine lost compression in the sixth cylinder in May 2018. I drove it about 5,000 miles during that time. It also has water in the oil. When I called them about it they said that the one year warranty is expired. They would not fix it. My mechanic was working on another car who's engine was rebuilt by WAM. That engine also needed to be redone. I have a new mechanic and he has had bad experiences with WAM and so has the guy who rebuilds engines for him. My old mechanic has used WAM many times and says that they used to be good, but now some employees have changed and their work is no good any more. My new mechanic would not use them either.
My Dads mechanic sent Dodge 4.7 heads to them for full valve job, and he thought, new valve seats. Mechanic wanted the best job done. Plus, these heads are notorious for dropping seats which any skilled machinist/mechanic would know this. Now, only 9 months later, less than 5,000 miles, head drops a seat, and damages piston. $950 down the drain to start. WAM refused to do anything. Nothing. So, I take heads to a skilled machine shop in Santee. Not only were the valve seats not replaced, but the one that dropped, you see where WAM peened it half azz. All new seats, redo WAMs work is $750. Dads rental car 3 weeks probably $600. Mechanics labor to R&R heads undetermined. Costs are adding up quickly due to WAMs shoddy work. Will file complaint with BAR, then small claims. WAM could have done the right thing and fixed in house for low cost but again, refused to do anything. Dads mechanic (long time friend of mine) has stopped sending work to WAM, and I'm passing the word on to my extensive list of friends in the industry of this experience.
