    Will EGR delete cause rich running symptoms?

    Like the title says...Will EGR delete cause rich running symptoms? I did my intake gaskets recently and deleted my egr at the same time. I have not tuned out the egr yet. I have white smoke on start up, it lasts until the engine reaches operating temperature. The smoke smells rich, almost...

    setting distributor (cam retard) on 5.7 vortec with aftermarket distributor

    Just another note...when I brought the truck to the shop it was at -8. When they adjusted the distributor -6 was as close to spec as it would go. I was at the shop a few months back for the same issue and the timing as -13 and after adjusting -6 was as close to spec as it would get. I've...

    Just did intake manifold gasket...still losing coolant. Nooooooooooo!

    It's a 98 5.7 vortec. I'm really hoping its air working its way out of the system. I'm gonna retorque the intake bolts to 11ft/lbs...do these bolts loosen off during heating/cooling of the motor? Thanks again.

    Just did intake manifold gasket...still losing coolant. Nooooooooooo!

    Yea...I'm hoping its air working its way out...really hoping, pulling that intake is a pain the arse. If I got a vacuum where would I hook it up to pull the air out? Also, I thought the oil and coolant mixed more so than the oil floating on top of the coolant. Thanks.

    Just did intake manifold gasket...still losing coolant. Nooooooooooo!

    Hi. This is my third post in three days. I just did the intake manifold gaskets a few days ago. I've marking the coolant level in the overflow tank while the truck is parked overnight to try and get an indication of leakage. It seems to be dropping slightly after each night. My only hope is...

    setting distributor (cam retard) on 5.7 vortec with aftermarket distributor

    Its got nothing to do with the wires being too tight. The distributor needs to be turned slightly more counterclockwise, but it's hitting the hold down bolt. Which is why I want to elongate the hole for the hold down bolt. What do you mean by moving it over one tooth? You mean the...

    setting distributor (cam retard) on 5.7 vortec with aftermarket distributor

    Hi. I just made a post a few days ago about my intake manifold gasket replacement. Now I'm trying to get the timing correct. The truck runs, I brought it to a shop to get the cam retatd adjusted. I was -8 and after adjusting -6 was as close to zero as the mechanic could get. The distributor...

    Filthy intake manifold/valley/lifters...how to clean???

    Well I finish the job. The truck started up on the first crank. I let it idle, poured some ATF in the motor, let it idle some more and then changed the oil. All in all it went okay, my most involved fix yet. Did the intake manifold, valve cover gaskets, spark plugs, cap, rotor, PVC valve...

    Coolant leak...need help diagnosing/finding the problem

    It's not running hot. But then again I haven't been driving it since I noticed the external leak. However I was loosing coolant prior to this. I'm assuming it is the intake gaskets as i have white smoke/steam when I start the truck, until it warms up and no external leak. Where is this...

    Coolant leak...need help diagnosing/finding the problem

    Ok thanks. I'll have a look. If it was the intake or head gasket would it leak externally like I described above. Previous to this I have had dropping coolant levels but no external leak and white smoke on start up. From the research I've done these are the symptoms of a leaking intake...

    Coolant leak...need help diagnosing/finding the problem

    98 k1500, 5.7 vortec, 4L60e. Hi guys. I need some help. My truck started leaking coolant yesterday. I drive, the motor warms up to operating temp, I shut it off and the coolant will begin to leak. About 50 ml or so. Then it will stop. I assume it leaks because the system is pressured...

    Power washed engine bay, now no start!

    Like the title says. I washed the engine bay, I made sure not to directly spray the alternator or electrical connections. The truck started immediately after washing, I let it sit for about 45 minutes and then tried to start it again. It didn't want to. It tries to turn over but seems to...

    Code P1345 - Adjusting Distributor

    Hi I have a P1345 code (1998, 5.7 Vortec). This code is related to the camshaft and crankshaft correlation. I was wondering if the truck can run "fine" and still have the timing off. I know the cam retard has to be within + or - 2 degrees. But if its outside the 2 degrees will the computer...
