Warning! Check your Engine for oil seep/leak.

[AWGD8]

Guys, I was qouted today by my local Infiniti service dept in the amount of $2,800 to fix an oil seep coming from the timing chain cover. My 2008 EX35 now has 76k miles. I noticed this last year and I thought I only spilled engine oil during my oil change. So I cleaned them up with engine cleaner and it was dry for a few months until I totaly forgot about it. It just happened that I did check my engine and noticed this issue again.

It appears that it is happening more frequent now due the miles accumulating...

Here is the picture I found online and this is a G37 VQ engine. Mine only has oil seeping , but my dealer will fix it under my Elite Extended Warranty.

Is seems like the paper gasket is the culprit. Possible 2008-2012 VQ engines might have or will have this issue once the miles is nearing 100,000.

I know sev , one of our forum members here , had the same issue like this and he probably the first guy who mentioned his timing cover was just replaced due to leaks.

From what I read the 2012+ VQ engine might be safe since they change the gasket from paper to metal...

So , before your warranty expires, check your engine for oil weep/seep or leaks!

Did an engine clean a few months ago and didn't notice anything then, but will do a check this weekend.
Appreciate the warning......Cheers...

Thanks for the heads up AWGD8! Will definitely keep an eye out....although...my EX hasn't even hit 30k miles yet.

AWGD8, do you know if it's possible for MY08-11 to change from paper gasket to metal gasket?

I read that this was changed for the 2012+ G37. I would assume the EX37 has a newer gasket.
This covers by powertrain warranty.
