Limp Mode after Steam engine clean

wtolbert

Question for those that are mechanics or may have had the same experience I'm facing.

I took my 370 to a car detailer in preparation of trading it in the next day at the Porsche dealership. My Z was running fine prior to the detail but the check engine light was on. This light was on prior for a couple months. I assumed it was due to my bolt on headers and the car needing a tune.

Once I got my car back and drove off from the detailer it was in limp mode. Engine wouldn't go above 2500 rpm's or faster than 60 mph. The detailer steam cleaned the engine without my permission. After taking my vehicle to Nissan the diagnostic was intake timing sprocket, solenoid, chains and guides with code P0021. Total charge $3610.22 plus $240 for diagnosis fee!! I found this out as I had an offer on the table from Porsche for a payoff and the news ultimately cost me $4k in the deal.

Nissan would not confirm or deny that the detail shop is responsible but are saying they don't recommend anyone steam clean a 370z engine. Porsche is claiming that steaming an engine wouldn't cause this issue while also saying they don't know anything about Nissans. Has anyone else experienced this? I'm trying to be courteous to the detailer offering him to pay half of my $4k loss but he is refusing. Wanted some input before seeking civil action.
