    2002 Trailblazer airbox question

    Thanks for the quick reply.... I actually don't plan to gut my airbox. I just don't know how good that seal is where the pipe goes in the hole. I think maybe it could be sucking in non-filtered air if it's not sealing well. I am thinking of just putting duct take over the hole that sticks up. I...

    2002 Trailblazer airbox question

    Good Evening, I saw posts regarding the airbox and removing resonators and using "cold air" intakes. My question is this... Where the intake pipe goes into the airbox, there is a piece that goes up into a resonator space in the air box cover. My concern is I can't verify that this is making a...

    Can the LL8 be cranked for testing outside of vehicle?

    Very nice Mooseman. The whole scan tool is probably cheaper than the dealer nowadays. ToolKeeper, when you say Tech2, do you mean the official GM tool?

    Can the LL8 be cranked for testing outside of vehicle?

    I need to get a different scan tool that can do the crank/cam relearn. I have a simple scan tool. I started going down the rabbit hole of scan tools. I'd like one that can do the relearns but it also bi-directional and can record many data points at the same time. Oh, and it would be nice if it...

    Can the LL8 be cranked for testing outside of vehicle?

    Thanks for the input. It isn't a huge deal, just a bit strange. If it's idling at 700 rpm in park, I touch the throttle a tad to rev it slightly, it will fall to about 400 or so and almost die but catch it. Sometimes the oil pressure warning comes up for a second since the rpm fell so low the...

    Can the LL8 be cranked for testing outside of vehicle?

    A follow up for everyone. 2 weeks ago I got my cylinder head back from Head Works of Nashville. They did a fantastic job. They confirmed most of the valves were leaking on the head remanufactured by Clearwater Cylinder Head. They put all new intake valves in. I put it on the engine and got 90%...

    Youtube - Car Wizard - Tollkeeper?

    Seems like an old thread but has been revived. On a personal antidote, an older couple at church has a 2009 TB and have just over 240k miles, and he has had no major repairs. They have owned it since either new, or close to new. They are early 80s and I get the impression that he services...

    Can the LL8 be cranked for testing outside of vehicle?

    Bad news. The engine leaks out of every exhaust port and one of the intake ports. Here's my leakdown results. This is with 100 psi pumped in at TDC of compression stroke. 1: 80psi, mostly crankcase, but leaks out exhaust valves 2: 80psi, mostly crankcase, but leaks out exhaust valves 3: 30psi...

    Can the LL8 be cranked for testing outside of vehicle?

    Thanks Mooseman. I'll do a leak down test. I was aware of the rivet issue with the head gasket, and I was sure my rivets were all in places where there was a cutout in the head/block.

    Can the LL8 be cranked for testing outside of vehicle?

    I tested again and got: in order 1-6 185 150 150 185 190 190 Cylinder 4 went from 140 to 185. I think my tool is wonky. It's a Craftsman test kit I got about 10-15 years ago. I do recall weird test results before and shrugged it off. The engine I got from a junkyard for my Alero, the...

    Can the LL8 be cranked for testing outside of vehicle?

    I honed the cylinders. They weren't that bad to begin with. The cylinder head was remanufactured by Clearwater Cylinder Heads. I think my pressure gauge might be the problem. I am getting inconsistent results with it. I think perhaps it isn't seating properly in the plug hole. I'll look into it...

    Can the LL8 be cranked for testing outside of vehicle?

    Well I cranked it. It delivered enough oil pressure to trigger the switch, which is good I suppose, especially for just cranking. The compression does concern me though. Cyl 1: 180 psi Cyl 2: 150 Cyl 3: 140 Cyl 4: 140 Cyl 5: 180 Cyl 6: 180 I'm not sure what the compression is supposed to be...

    Can the LL8 be cranked for testing outside of vehicle?

    In the past I have cranked junkyard engines with the starter motor to see if they have compression. You can also determine if there is oil pressure. (obviously not a reliable determination of how much pressure since crank is slow). But you can see that it is building something. These were older...

    SUPPORT How to delete account

    Thanks. I'm grateful for the kind words here. I am not "switching" to the other site. I just have to realize with any form of anonymous communication, there will be certain personalities to deal with. I think this keeps a lot of people in "lurking" mode and not participating. I have a social...

    SOLVED! 4.2L LL8 Harmonic Balancer Removal/Installation

    Mooseman, thanks for the input. The X foot pounds + Y degrees of angle means it's a TTA (torque to angle) bolt. But that doesn't necessarily mean it's a TTY bolt. It can be, but might not be as well. As you probably already know, TTA is handy because it guarantees a certain amount of clamping...
