    What is this box and why is the top wet with gas?

    If the EVAP cannister is saturated with gas the purge solenoid is not purging when your driving, it's supposed to trap the evaporating gas fumes when the vehicle is off; then use engine vacuum when the vehicle is running to draw those trapped fumes into the intake to burn them It is possible...

    Burning oil

    The rotten egg smell means at least one bank is running rich, if it's not throwing a code for that it means the 02 sensor is not reporting the rich condition so it's likely reporting a false lean condition & the PCM is trying to compensate by dumping more fuel A quick test is unplug both...

    Is New Engine Break In Procedure Still Necessary?

    No, drive it exactly like you drive whatever else you drive; engine break in is an enduring wives tale If it's a rebuilt do the first oil change early, other than that let it eat

    Anyone used adapters to put 5 lug wheels on a 6 lug truck?

    Most people have used wheel adapters, usually just once because the wheels inevitably come off when driving; but it sounds like a good idea to most of us at least once

    2001 Chevrolet Tahoe Won't Start

    Here's the problem, in California you will need to buy the CARB approved catalytic converters & replace the air intake with a stock system or aftermarket that also has a CARB number to get a passing smog test If you are going to pay a shop to do those 2 things you are going to spend a lot of...

    2000 GMC Yukon 4x4 Engine & Transmission Replacement

    Buy a reman long block exchange & drop the transmission off to rebuilt while the shop has it out, that vehicle is a keeper since they age so well; might as spend a few bucks once and be set for another 300k

    DOD Delete now ticking

    If it's ticking you either have too short of pushrods or your bleeding oil pressure by whatever scheme you used to block the towers (I use the drive in plugs & the valley cover that's designed to block them as well) Lifter soak isn't the issue, it's not needed on any roller lifter with a non...

    Why The Gen-V LT Outshines The LS

    EPA standards escalate, when tuning was able to hit the mark with greatly reduced EGR the factory eliminated the EGR system and ground the cam to allow a very slight EGR effect all of the time; this was sufficient to meet the EPA standard until they increased enough to once again require more...

    Why The Gen-V LT Outshines The LS

    As for the AFM, having both valves disabled in the closed position increases load on the engine, GM designed it that way. Take any syringe & place the plunger in any position you like, then put your finger over the end to simulate closed valves & try to move that plunger in & out; it will have...

    Why The Gen-V LT Outshines The LS

    To get EGR doesn't require a seperate EGR system if you have VVT, the exhaust valve can be left slightly open at the start of the intake stroke & exhaust will be drawn into the the cylinder whenever the VVT wants it The EGR effect is using inert exhaust gasses to pollute the air/fuel mixture...

    Why The Gen-V LT Outshines The LS

    I don't think it can be eliminatedwith the stock cam grind but it likely can be reduced to a small amount by disabling the VVT If the aftermarket ever starts developing VVT performance cams & the tune can be tweaked to capitalize on it the pre VVT engines will be relegated to dinosaur status...

    Why The Gen-V LT Outshines The LS

    VVT has the capacity for great things but GM uses it to enable EGR without an EGR system, the hold the exhaust valve open momentarily when EGR is commanded to injest exhaust back into the cylinder Because of the application I thinks it is a waste of technology that damages the engine like all...

    Why The Gen-V LT Outshines The LS

    I didn't say VVT was pointless, I said it expands the optimal rpm range the cam can deliver over a cam that has a static grind But to gain that expanded optimal range comes at a cost of more moving parts & more complex system to apply the changes on the fly to gain that benefit The gain...

    Why The Gen-V LT Outshines The LS

    Simplicity equals reliability, one roller cam with 2 gears, a chain measured in inches & pushrods as a means to control valve events is infinitely cheaper & more reliable than multiple cams, multiple gears & a timing chains measured in feet with multiple tensioners to control the same valve...

    Charcoal canister

    The filter medium from the cannister cannot get into the fuel tank when the cannister fails & the fuel pump has nothing to do with the EVAP system so I wouldn't start changing those parts The tank vents to the fuel nozzle when filling with fuel, not through the EVAP system, there is a path to...
