Clogged MAF due to no air filter for 2100 miles
2014 TL Acura v6 broke down due to a clogged
MAF. MAF was clogged due to no air filter. Traveled
to the beach. Could sand be in engine?
Yes,traved through the engine.. even with an air filter in State like FL, engines wear faster from grit and sand. NO, air filter sudden death.
Unless you just drove through a dust storm, this has been coming on for awhile. Most likely since your last service visit where you were charged for a new air filter. Sounds like they forgot to put the new one in! Have your oil changed, drive for a week or two then have it changed again. This should get any excess dirt out of the engine. Make sure they change the oil filter both times as well. HTH. -Jim
I had a borescope done and have showed the pics to a ASE certified master tech and a field office person from the dealership look at pics. They both have different opinions. One says you can see the sand build up on a piston and the other says its carbon build up. ASE says a car with less than 25k miles should not have carbon build up and carbon build would be showing up on all Pistons not just a few.
You may be able to remove the spark plugs of the effective cylinder(s) and get a sample of whatever is on the piston(s). I really don't know but it's worth a shot. I'd think that if it were sand, with the pistons traveling up and down as fast as they do, sand wouldn't just sit there on top of the pistons. Doesn't sound logical to me. Also, if you had that much sand in there you'd have ring damage, cylinder wall scoring, and most definitely oil burning as evidenced by blue smoke out the tailpipe. If you're looking to hang blame on someone for any damage other than the MAF that's going to be hard. Their first line of defence will most likely be "there's no way WE forgot to put in the new air filter, YOU must have taken it out!" Personally I'd never believe that. Shops, even dealerships, make mistakes all the time. The trouble here is time has passed and if you're not having any issues the shop is going to claim "no harm/no foul". If it were me I'd do the oil changes and keep an eye on things. I'm assuming that you're still covered by the new car warranty. Keep all of your receipts and if you have an engine failure, get a new engine for free. It's not your responsibility to have to go behind and babysit the shop's work. You took your Acura there in good faith that the service would be done and done correctly!! Not your fault! HTH. -Jim
Car has been sitting at dealership for almost 4 weeks. They admitted they were at fault. The borescope showed scratching on the cylinder walls: opinion of pics: normal cylinder wall will have a cross-hatch pattern on it from when cylinders are board and honed.These are the angled lines that cross each other sideways that you see.All of the vertical strait lines on cylinder walls were caused by the sand getting into cylinders and getting caught between the compression rings on pistons and cylinder walls,causing damage to both rings and the walls.Also the Black and Shiny build-up on top of the pistons is sand.the top of the pistons should not have any solid partical build-up at all at just over 20k miles
Also, compression test readings they provided: all 6 cylinders read 275 psi
