You are correct. I read the OP initial post and saw replacement timing chain and position sensor. Didn't see the new long block coming into play.

It's too bad. We need someone with this problem to see how much wear is occurring on the sprockets.

One person posted pics of a new chain and old and the old one was actually stretched quite a bit. The tensioner ratchet was fully out.

I can't remember the length so don't want to write it down and be wrong but I thought it was around the 2/3 of an inch mark.

I've seen the oil change interval length being discussed on this and other forums. In my own opinion, I feel there is not enough evidence to decisively safe this plays a major (if any) role in the timing chain stretch. That being said, I'm a firm believer of changing oil regularly using a quality oil.

If the issue was caused by fuel in the oil, wouldn't Ford change the recommeded oil change intervals, or even the type of recommeded oil for these engines? To me, I think the fact Ford changed the timing chain design is the most telling. However, perhaps it is a combination of both bad timing chain design/oil dilution.

MustangJim21

Correct. The longblock will have new heads. I spoke to the tech and he confirmed they have also ordered me new turbos!

The SHO's used to run 5w20 oil, so speculation is the 5w30 that our engines use(same engine) is to prevent the fuel dilution. Again speculation but kinda makes sense. Plus ford has a new PCV to help combat this.

It's also been document that the new chain and tensioners don't fix the problem. So the next logical step is to see if the sprockets are wearing due to a slack chain.

Way back when most V6 engines used timing chains instead of belts, sprockets use to be part of the replaced items on a timing kit. Why is Ford not replacing the sprockets?

vozaday

Or tensioners. I don't know. It would most definitely be worth it to pay to get them changed out of your pocket while they are in there. Maybe they are hoping it will push it out of warranty?

And the timing chain TSB says to replace the oil with a full synthetic. Pretty sure they are looking hard at fuel in oil being the cause.

MustangJim21

Thank you for pointing that out. I missed that the first time i read the TSB; don't know how!!!!

I stil believe there is something else going on besides oil dilution. Just my opinion. I look foward to seeing the day Ford finally gets this figured out, and we know the culprit!
