Complete Engine Cylinder Head Assembly 1.4L Replacement for Chevy Cruze Sonic Trax, Buick Encore Stock DOHC 1.4 Turbo # 55573669 55565291 12703173

Works good no problems

Fue una buena compra cumple con los parametros de calidad

Not even one star was garbage and three days late thanks for wasting money I didn’t have

Identical to original and very high quality

Didn't include some plugs we expected it to which required a long drive (next state over) to get the one piece withing 150 miles.

Buy a tap size m10x1x8 to finish the threads on the passenger front oil galley plug to swap the oem plug over to the new cylinder head other than that car still runs ships with cams almost tdc

Cam thrust distance needed to be increased. Cams would not fit into housing bore.

Just exactly what I needed

So I bought this head in August. It took a while for the mechanic to install it as there were a few other things that needed to be replaced and he couldn't work on my car continuously. We a week left where I could return it when he finally got the car all back together. When he went to start it up it still wasn't right. Two dead cylinders on the first try. So he did a wet test. Compression did come up but not enough. He checked the timing twice and all was good both times but it still seemed like timing was out. This is even with new plugs and coil pack. Sent the Block out to be rebuilt. Rebuilder found nothing wrong. We had both heads sent over to the rebuilder. Turns out ons of the lobes ont the one camshaft had a flaw that was causing the valve to flutter open when it was supposed to be completely closed.(Bad grind) He set the shaft up on a lathe and showed me with a dial indicator. There is a 5thou jump in three spots were it should be in the open position. For this I give this head a one star because this should be checked through Quality control. This shaft should never have passed inspection. Car is running fine know. We used the cam shafts from the original head.
