i finally took it in today. it's a head gasket. the car has barely
any mileage (i consider 60k a joke.) is this common? man, i should
Hi,
I thought it was premature, but when I blew a headgasket at ~69k on a
Toyota truck, my machine shop guy said not at all. He said early
failure's not unusual on today's engines cuz the heads are generally
"empty" (not a lot of metal) to maintain a lot of coolant flow. So they
suffer a fair amount of thermal warpage.
He told me the good news is this warpage is pretty much "one way." In
other words, the head warps, you resurface it and install new gaskets,
drive off happy and don't worry about it again. On the Toyota, he was
right. I haven't replaced the gaskets on my Subie yet, so can't speak to
that engine.
If it's just a little seepage, and you haven't already committed to
having it torn down, a little bit of Aluma-seal may help. My head
gaskets drip occasionally, and I add about 1/4 tube (the aluminum powder
stuff, not a liquid variety) at each coolant change, about once a year,
and it generally takes care of business. Lots easier and cheaper than
replacing head gaskets that aren't blown.
Best of luck,
Rick
