Has anyone put one on their new Tahoe/Yukon/Suburban yet? Do they make one specifically for the new models or did you have to modify one? Is it true that GM will void a warranty if there is engine trouble after install? I would hate to install one and have the dreaded valve spring issue and lose my warranty because I installed a catch can. TIA
You might query your dealer. I mean, I don't see a dealer calling out a benign aftermarket part on your engine if there is warranty work to be done (and get paid for). Also, I think if GM somehow found out your engine had a catch can (something I can't see happening) and refused warranty payments on a known systemic problem on your engine, I think you wouldn't have much trouble interesting an attorney to get that rectified (likely a strongly letter would do it).
When I ordered my Moroso catch can, it came with install instructions but they applied to earlier model SUV's/Trucks (which was fine with me as mine was an earlier model, 2007). There was a picture on the Amazon page where I bought it from of an install someone captured on their newer model, seemed very straight forward. They mounted it with what looked like the same fastener which holds the windshield washer tank to the body (versus to the alternator stand on mine). There are cheaper alternatives to the Moroso unit, installs would all be basically the same, I think.
I really like having it on my 2007 port injection engine (for piece of mind and a monitor for what is going on inside my motor). I can't imagine owning a direct injection engine and not having one.
