the 6 cylinder Head Gasket leakage Issue

Howdy!

I own a 2012 Tacoma and recently replaced my spark plugs and noticed oil on my spark plugs.. As yall may know this is a fairly common issue in these tacoma's from what I am told. Tacoma is my favorite vehicle, but I dont see fixing the head gasket as a long term fix, from what my experienced mechanic (not a dealership mechanic, but instead a friend who builds race cars) tells me.

So I have run into a conondrum. To buy a newer Tacoma Offroad edition, (2017-2018) and hope it doesnt have the same issue, or go another route (Tundra, Colorado, Ford, etc.). I hate to give up my tacoma, but It just seems that Im gonna have too.

So my question is, do the newer tacoma's have this same issue?

Kind Regards,

Connor

 

It's not common in a 2012. How much oil is on the plugs? Is it on all plugs? Almost sounds like you want a different truck and are using this as an opportunity to get it. Small amounts of oil on the plug isn't exactly abnormal.

 

Oil on plugs is not an indication of head gasket failure. More so a valve cover gasket leak. Most head gasket failures have been 2005-2006 years.

 

If you have oil on the electrode it is either coming from a leaky intake valve seal or a carbonized oil control ring on that piston. Run a good fuel injection service through it and run a good oil conditioner for the next few oil changes. It should clear itself up. If not you got bigger issues. If the intake valve seal doesnt seal up those are not too hard to change.
