Looks like a bad seal, or gasket? Anyone tell where this might be coming from? Just got back from a 80 mile run and saw this while parking in the garage...

2006 F4 w/3,600 miles....

 

[ARAMIS]

It´s curious but only saw this in a mew model F4RR 2012!
Probably isn´t the same issue but I leave it to the experts...

Pull the side panel off for a closer look. :stickpoke
Kinda hard to guess with all that plastic in the way.

Yup…that's my plan. I wanted to get an initial pic up to see if it jumped out at anyone. I'll post some additional close ups.

At first glance, it looks like it's coming out of the "F4" piece, but I'm not sure what component that is as of yet…

 

[micwhitt1]

That's the crankshaft timing cover. Could be the source, but again, you won't know until you get the plastics off.

 

[The_castle]

The crankshaft timing cover has a rubber gasket.

You can remove the cover using an 8 mm socket. Inspect the mating surfaces then clean or replace the gasket.
Do not over tighten the 5 bolts holding the timing cover in place - refer to the service manual for the correct torque require for those bolts or someone here will have that info and may add it.

 

[Donsy]

Dave is spot on, very common place for minor problem, use some Form-A-Gasket when re-installing cover after clean-up.

 

[chrisbanks00]

Here is closer pic, just to confirm what looks like has already been said. It's very minimal, but I'm sure would only get worse from here. Once removed, is oil (or ??) going to pour out? And where would I acquire a seal for this?

 

[rsawkins]

This is just a cover, a bit of oil might come out but not a lot. Either take the o-ring to a seal place and match it up or do like Donsy says and use some stuff to seal it up.

10 min job

Here is what you will find when you remove the cover. Some oil will come out. Clean the cover well, and inspect the seal. If it's bad you can check with Noel. Put a skim layer of gasket sealer around the contact surface before you bolt it back on. Like Dave said, check the manuals for the torque specs, slap the bodywork back on and poof! you're off.:f4:

 

[chrisbanks00]

Love it when it turns out simple. I'll find some "Form-A-Gasket" sealer along with getting a torque wrench before taking it apart.

@ Ian SAVS ~ Thanks for the pics. Very helpful....

10Nm torque should be fine.

 

[chrisbanks00]

One last thing...looks like you can get some Form-A-Gasket #1, #2, or #3. Is there a preference for this type of job?

Anything with a reasonable temp rating and oil resistance RTV Blue or Permatex Black etc.

 

[theknurl]

goop?

chrisbanks00;
you do not want Permatex #1, 2 or 3.......thats crap from the '20s

you want Permatex RTV Form-a-Gasket silicone gasket maker

I use the high temp orange because it's easy to see any little pieces left around when you remove the cover

take the O-ring out of the F4 cover...flatten it on a piece of plate glass with ~80 grit wet or dry sandpaper......never seen a flat one:wtf:

remount the O-ring and use a paper thin coat of Form-a-Gasket over the cover and the O-ring:naughty:

do not over torque the bolts

:drummer:

Yeah Noel, we don't have the Permatex #1,2 or 3 over here.
I've used the Permatex Ultra Black PX #82180 with huge success just recently on a 312R which leaked like a Leyland.

Next time I'll try and get the Orange one's

bet the aircraft guys use the old shit:wtf::wtf:

I'm not kidding:naughty:

 

[chrisbanks00]

I picked up the Permatex RTV Orange from the auto parts store...thanks guys!

 

[micwhitt1]

While you have the cover off, take a look at the seams where the upper and lower halves of the crank case meet (where the red arrows are pointing). I hear the joins are notorious for being uneven (mine were). Take an emery board to even them up. Could prevent future leaks from that area.

 

[Ian SAVS]

Hey, those are some nice arrows Michael!
