It is a little bit colder these days in montreal...
This morning I started the 1998 Rodeo (3.2/ Automatic/ 50K miles) and between 1900 and 3000 Rpm I hear a whistle comming from the engine. It cleared away as the engine warmed up. I did not push it at all so I can't tell if there is a power loss or not. First day it does that.
Is that the first sign of a leaking intake gasket?
Could it be a stupid idller that starts to rock not roll?
Anybody has ever seen this before?
Should I simply raise the volume on the radio or leave the truck in the driveway for a week to punish it?
Honestly, I feel that most of the problems on this truck give fair warning *and* can be fixed for pocket change if you DIY.
Except for my ABS failure, everything else has been relatively simple for a home mechanic. Thankfully, the ABS failure was covered under warranty, not that I cared for the system. However, in the unlikely case that I ever decide to sell the car it is a nice thing to have.
112K miles on my '99 Passport
Gas gauge problem: Dropped the tank and fixed the fingers on the fuel sender.
Intake Manifold: Replaced both gaskets at 40K miles, no problems since.
O2 Sensor: Replaced bad sensor
Valve ticking: Happens every now and then so I change the oil and it goes away.
It's been smooth sailing otherwise *knocks on plastic wood trim*
It still idles smooth and I'm getting a consistent 18MPG driving to/from work near NYC in moderate traffic everyday.
Just one question here for everyone: Is WD40 an appropriate "lubricant" for a bearing? Isn't the stuff like 80% solvent?
I don't know the specifics of the bearing in the idler, but I'm guessing that it is a sealed unit and once it starts to squeal it should be replaced. I think you're risking a broken/damaged belt if that thing starts to seize up.
