Paint Loss from Cylinder Head Cover - known issue and cause?

[KEET]

Hi All,

 

FG 2010 XR6T; Sydney based.

 

I have paint bubbling and flaking away on the Cylinder head cover; wondering if this is an issue anyone else has comes across.  Obviously not a corrosion thing, wrong materials.

 

Will upload a pic if I can work out how!

 

I'm mildly modified,292rwkw running higher boost tune reliably since 2016. My cooling set up is OEM.  

 

Whilst a bit annoying cosmetically what I'm actually worried about is whether this is indicative of a spell of running at excessive temperatures?  I'm thinking back to summer holiday traffic jams where you're radiator fans are running the majority of the time, certainly had my share of those days.

 

I'm not in the habit of lots of aggressive pulls from low speed; so if it is indicative of heat ,wondering if the thicker fenix radiator might be the solution?   Whilst I have had my eye on a better intercooler for a while I can't help thinking that is going to further impede flow to the radiator (probably making it no better).

 

If anyone knows this to be turbo heat that might send me the other way, but in my very limited mechanical knowledge I think it is more likely the boring solution (radiator). 

 

Appreciate this is pretty vague and I'm probably being a bit of a hypochondriac about the pride and joy.   Car is serviced on schedule or more frequently.

 

Any experience from others on this grateful received; would love more mods but want to nip the emerging issue in-the-bud as a priority. 

 

Thanks,

KEET.

There’s no issues mate, it’s a common fault with FG series depending on some years/months they were built. 
 

Just looks average, nothing more

Also have a 2010 XRT and had paint bubbling and peel from the front of cover. 

Was running at 105 degrees and fans constantly running. 

Replaced the thermostat and temps returned to normal and no more peeling.

2010 F6 here no bubbling but slight fade on the cover, running a cooler theromostat

Thank you guys, really appreciate you all chipping in with your thoughts on this; maybe as a precautionary I look to switch out that thermostat next tie she's in for a bit of TLC with my trusted (because he's nit picky) mechanic.

Cheers.

He won't do the repaint without taking the engine out so that's on my amateur ass to do; got some stuff rated to insane temps...

I think you misunderstood them. Removing the rocker cover does not involve removing the engine.

My FG rocker was bubbling, and then paint came off when Ford cleaned the engine to replace timing cover seal.

I just bought high temp paint and repainted it in the car. Not as good as doing it properly, but looks heaps better and will get me through to whenever I next need the cover off and can paint it properly.

That's exactly where its coming off mine too!  Yeah I think you're right maybe super light sanding with fine grit grade; clean it back throughly with alcohol based cleaner, then mask off the area just using heavy fabrics and a little bit of painters tape.

 

Thanks for the pics; now I have a little lockdown project....likewise lockdown is the perfect time for a good detailing session.  There is a little silver lining after all..
