oil

My 2005 trailblazer ls had an oil pressure problem then while driving just turned off. The motor cranks but does not start does it just need an oil pump replacement? Shouldn't it turn over for just a couple seconds?

I’m about 1,500 miles away from my next oil change, but the warning came up on my dash that I had low oil pressure. The message disappeared quickly and because I was in the middle of the country, I continued driving home. The message didn’t pop up again. My oil light is broke, so the only...

Hello trailvoy users, I'm trying to remove the tube where the oil dipstick sits in. Reason be is because I'm trying to remove the exhaust heat shield. I already have all the rusted screws out the shield but the oil dipstick tube is in my way and I'm trying to remove it and looked all over the...

I've used Mobil 1 syth oil since I got my TB. It's a 2005 LT that I bought in 2007 with ~45k miles. It now has almost 190k on it and I was told that due to the age of the engine, it might be best to NOT keep running synthetic in it. What are your opinions on switching? I'll still keep the...

Good Afternoon Everyone !!!... So a few days ago I noticed there was white smoke coming from my exhaust, and throughout the day I started realizing that it only appeared on the initial startup and NOT when it was in normal operating temperature anymore. The truck runs smoothly with no rough...

I have been sitting on this problem for a while now and reading horror stories about the lifter/AFM/replacement engine costs so I finally decided to start investigating the problem to see what I could find. My engine is only misfiring on cylinder 4 so I have changed the plug (have the others to...

I have a 2008 Chevrolet Trailblazer LTZ 5.3L V8 140,000 km. Two days ago when I started the car and began driving, I noticed the “Check Gauges” light had come on and the oil pressure gauge needle was exactly at 0. I immediately stopped my car and shut down the engine to check the oil level which...

Do I need to drain the oil in order to change the oil pressure switch? I'm thinking yes, but I want to make sure.

Since I've bought my trailblazer used, I've changed the oil three times, and have used Chevon Supreme 5W-30, which the guys over at bobistheoilguy.com say is about the best dino oil you can get. I don't want to use full synthetic, and would rather stick with straight dino oil. Anybody recommend...

Hey everyone! I've been stalking this forum for about a month now since buying a 2004 Trailblazer LS. There is a TON of awesome info on just about anything I need, and even a bunch of videos. I used several of these resources to change my spark plugs and clean the throttle body at about 91,500...

I am not new to the site, but have used it to fix small issues with my 04 Trailblazer. I want to thank everyone for their posts. I do have a issue with my trailblazer and i am hoping that someone can point me to the right thread or maybe say what needs to be looked at fixed. 1. On vehicle...

About 2-3 months ago, I had a bit of a run-in with a guard rail and some black ice, and my '02 Bravada sprung an oil leak from a corroded metal line located on the driver side. The line runs down and connects to a rubber line that goes underneath the fan and radiator and then turns into another...

My oil pan shield/engine protection shield is missing and I would like to replace it. I am having troubles finding a part number to order it. Any help would be greatly apprectiated, for 2007 Trailblazer, 4.2L, 4WD.

Recently I overfilled the oil by about a quart. I drained it before I drove, so it just idled for a few minutes. After that, the oil pressure gauge stayed pegged out to the far right. A few weeks later, the odometer and speedometer went to zero on the interstate. After I stopped and...

So, I just accidentally added 1 quart of 10w30 instead of 5w30 into the engine:duh: Really don't have the time to get it changed right now with work & trying to move to my new place, so am I gonna screw something up by adding the quart of oil and leaving it there for a week or so?

Hey guys, I just left the stealership and got my oil changed. Problem is I was on my way home and it was a kinda rough ride home. I stopped to fill up with gas and had a problem starting the truck. After about 5-10 tries the truck started, but I had to push on the gas pedal when I started it...

Hi, Well, we just bought our TB a litle less than a month ago, with 23,000 miles and change. It was a certified used vehicle, but of course we have zero insight as to how the previous owners treated it (and I'm assuming bad, because it was repo'd). Now, we're coming up on 24,000 miles, and...
