2015 3.6 Head


Recommended Posts

I have 2015 CROSSROAD with a 3.6 that has a little over 133,000 miles. The check engine light came on. Code indicates cylinder 5 is leaking down. I had the head replaced at a dealer since I'm gone more than I'm home and I didn't have time to do it myself. When i picked it up, the labor alone was well over $2,000 and that works out to around 12 hours. I have a few questions. I know there have been problems in the past on the 2011, '12 and '13s with the valves not seating right on the 3.6 heads. Is this a common problem with newer models? if it's not a factory issue, what would cause it with so few miles? Also, the 12 hours labor seems excessive for simply changing a head. Is that what the book calls for? I know, at this point there is nothing I can do about either of these things but I just need to satisfy my own curiosity. $4,300 is a lot of money for a head replacement and i'm a little butt hurt over it.

Could you list the code for cylinder 5 leaking down. There are no built in compression gauges on ICE engines that I’ve heard of.  Turbo boost gauges, yeah.

I don't know the code. I took it to the dealer and they did a compression check. I should have said #5 cylinder misfire was showing a code. I took it to O'Reilly's to check the code when the check engine light came on. I tuned it up and and changed coil packs and the light didn't go off. I knew I had bigger problems.

Sometimes people will have a used engine installed rather than have large engine repairs done.  But there is risk in finding a decent used engine as well.  New cars and repairs costs are higher right now. The car plants shutting down during Covid took out over a full year of vehicle production. Fixing older vehicles is becoming the cheaper option. Finding reasonable mechanics if you don’t have time to shop around. Definitely a challenge.
