**1.8 nu engine rattle fix** pics!!

Hello everyone! Just sharing some pics of my 2012 Elantra GL with the 1.8 nu engine, I work at a Hyundai dealer and one day I was looking at the tsb's and Hyundai finally recognized there was a problem with the block of some 1.8 engines and was ok'd to replace the block in my car because it was rattling.

Well my 1.8L isn't rattling so apparently the engine is bolted in tightly.

The OP likely meant to say that they're replacing the short block...the lower engine including all internal parts. Bad rings?

Easier to drop out buttom as a whole ... then take apart.

Il post a copy of the tsb when I get to work, the tab says that the problem is with the coating on the pistons and conecting rods.....but at our dealer just replacing the short block has never fixed the problem we have had to also replace the head, cams, lifters, cam holders..... Everything, in the end I would be cheaper and easier to replace the long block ( entire motor) but Hyundai Canada is a bunch of idiots and won't let us do it.

Mine makes some noise on start up, but goes away once it warms up.
Did your car do the same or did it continue even when warmed up?

It was the worst on start up because there is no oil in the oil operated lifters and passages to the cams, but once it warmed up you could still hear it just not as much. Yours will eventually get worse
