OMGWTF17MPG! Highway!

Thats just not right. I mean, I know it'* an SUV but really? 17?

Time for a tune up

nice, i really like trailblazers, ever since i drove one. factory specs for it are 21 hwy, and i belive that 4.2 inline six has 275 hp.

looks mint, very nice
now lets see you doing some major work on it :P

very nice truck, but yep you better get used to the gas pump i dont know anyone who gets over 20 mpg with that config.

Bahahahahahahahahahahaha... Jon... be nice to it. They like to burn valves which leads to misfires etc and compression checking shows the issue.

From the GM ESI FSM'* step 1 is "Remove oil pan drain plug. Drain oil and replace with a suitable plug." When you figure that one out..oh boy the fun begins.

Here'* what it looks like in there


Get a shoe horn out, drain plug is out to slide the pan on the frame.



Pretty much how it sits




The Envoy (twin sister) comes apart pretty well for the job



Nope, not tight on the left side


Nor the right side


Back is really roomy Funny part is..this is sitting down about 2-3 inches because the motor mounts aren't in yet. Hope have to disassemble the suspension to pull the mounts out.


The two top trans bolts are fun. They clipped the trans/transfer case breather tubes up against the bolts. Once you get those out of the way the passenger one isn't bad. (4 feet of extension and standing by the transfer case). The left one though.. I'm looking in through the suspension, see Dan'* hand?



FWIW pulling the head to fix the valves pays about 2 hours less than swapping the entire motor. We should have it running tonight. Motor is from a Trailblazer.

My gawd.

Fortunately for me, I think I'm done with working on cars. Now that the TGP is done, I have no interest in working on cars anymore.

That is, of course, assuming I don't bring a Fiero home this weekend.

thats pretty funny, your never DONE. something will break or youll want to change something else or you start a whole new car

Really...who the heck do you think you are foolin? Need the 05 TB pcm or any of the small parts off the old motor? Not sure if he'll let the coils go, but otherwise..I'm sure it'* all free to me. Pay the shipping and it'* yours as spares.

To pull the engine, you have to pull the fuse box apart, be a contortionist and work a few miracles. Gearwrench 82248 is a must.

Better grab some KY to help ease it on in.

Hmm.... I would like to have the coils....
