From: me on 19 Apr 2007 14:11 My 2000 Mazda Protege is smoking blue smoke at start up until it warms up and then it clears up. Has abt 127k on it and I am the 1st owner and have taken great care of this car What is likely cause? Valve guides? Ring job? I was hoping this car would NOT develop such major wear at 127k. is this abnormal or normal?

Valve guides? Ring job? Most probably valve guide seals. If it were a ring issue, it would be less apt to clear up after the engine gets going. >I was hoping this car would NOT develop such major wear >at 127k. is this abnormal or normal? Dunno, depends on the engine and how well you took care of it. Valve guide seals are pretty easy to do and not all that big a deal. Rings are a big deal. --scott -- "C'est un Nagra.

What you think a reasonable price would be to have valve guides replaced? I'm unemployed college student at the moment so cost is an issue. <g>

It's not a hard job to do yourself in the driveway with most cars, though you'll need compressed air to get the valve to stay in position while you change the seal. If the engine isn't mounted in some way where it's impossible to get the valve covers open without pulling the radiator or something (as is the case on my wife's Subaru), though, you might as well just keep driving it for a while and live with the smoke. Get the Haynes manual, look at it, and see. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

Prices are different everywhere. To find out how much just call a few good repair shops in your area.
