Yes, I checked. The tech told me that standing connecting rod side clearance was .325mm and max was .5mm. He said two of mine were over .8mm and all is the rest were between .5mm and .6mm

You did see this post from @Superchomper2003, right (Post #11). Look at the specs he quoted and compare to the table I posted.

Section 303-01C Engine - 5.0L 32V Ti-VCT/5.0L Ti-VCT V8

Yes I did see that , but what I was asking is where are you getting the illustrations checking rod ide clearance . I can not find it in the serive manual .

Like I said and you said ... the service manual doesn't show how to check it or to check it. But that doesn't mean it's not important, otherwise they wouldn't even show the clearance specs?

So what if engines are coming out of the factory with excessive side clearance - an obviously there ARE because some guys say their shop measured it and found some rods to be out of factory spec. If nobody ever checks it because the manual doesn't says so then that's crazy IMO. Any engine guy should know about rod side clearance, and if there's a spec listed in the manual he should check it.

Are you sure that is correct ?

It is the section in the manual I have that shows the clearance specs. Right off the top of the page.

If it's the illustration I posted, then yes ... that is NOT in the manual. Just wanted to show guys who don't know how a rod side clearance is measured. It's pretty basic engine building stuff, but not everyone knows how it's measured. You're getting too hung up on the manual ... what's important in the manual is the listed clearance specs. Any engine guy should be able to know what to do to verify if the engine is within factory specs.

Does your service manual show the same rod side clearance specs?

So my friend , when I asked about a manual reference . You failed . That s for a 5.2 not a 5.0 . But you really didn't fail because you are looking for an answer . Point is the 5.2 , flat plane crank , is ay defiant then a 5.o crank . I never thought of looking there . So can we put this to rest ? Besides If there was a bearing issue then a manual transmission would make the noise come and go ? Load the crank unload the crank . Just sayibg

Nope, didn't fail. This really shouldn't be this difficult.

Where does it say "5.2L"?

I see "5.0L 32V Ti-VCT".

----> I said: Section 303-01C Engine - 5.0L 32V Ti-VCT/5.0L Ti-VCT V8

FYI ... this is NOT a 2018+ manual, but for a 2015, so maybe the Sections aren't exactly the same - search for "connecting rod", and you should find the clearance specs. I'm betting the rod side clearance spec is the same for the Gen3. Please post up what your manual shows for rod side clearance specs.

You should know that the BBQ tick will never be "put to rest" until someone figures it out. It's like hunting for Big Foot ... you see the signs it exists, but just can't seem to find where they live - lol.

FYI .. the BBQ tick happens in both automatic and manual transmission cars. And yes, if the load on the crankshaft is changed I can see how it could certainly make possible lose rods ticking come and go. As you may or may not know, the BBQ tick can come and go just by the small load put on the crankshaft by the AC compressor kicking on and off.

Here you go . Can we agree to disagree ? Oh by the way I have one of these

Looks like you're looking at a 2011 shop manual (top of the screen). And the Section says 5.4L (Shelby GT-500 engine).

Look at a 2015-2017 or a 2018+ ... 5.0L. I'd venture to say all modular Fords will most likely have the same rod side clearance specs.

What's your manual show for the rod side clearance on a 2018+ ?

The manual states the same , but ther is no corrective action . Point is when a technician runs it to bid something that is questionable he /she should reach out for an answer . Maybe I am not like most ,but to the op I would like an answer so I can explain why tis is normal .

As I suspected ... the rod side clearances are all the same for 2015 to 2019. No surprise, thanks for that. Are we on the same page now?

So if you opened up a motor and measured all the rod side clearances and found 3 of the 8 to be out of factory spec, what would you do?

I don't care what anyone says ... parts being out of factory spec is a problem - out of spec parts is not "normal". Otherwise, there wouldn't be a clearance spec.

Just because there is no step to measure the rod side clearance, or no corrective action in the service manual for excessive rod side clearance doesn't mean nothing should be done. At least I wouldn't just let it go and send someone down the road.

Why do you think Ford says to replace the short block when something out of spec is found in the short block? I guess a shop could order a new crankshaft and new rods and do a rebuild, but then you get into new bearings for the new rods with the correct size codes and same for all the crank bearings and all that jazz - too complicated. It's just cheaper and faster to replace the short block assembly.

So what are you getting at ? As per the manual this is not something to check . Why would a tech check this ? I have the answer do you ?
