    2002 Escalade engine knock/tap?

    200,000 miles, so it’s got some wear. It’s been lasting longer and longer- the noise only really goes away after longer trips or above 2500 RPM. If I haven’t driven it for a few hours it’s pretty loud. It sounds like its low and towards the passenger side of the engine. Sent from my...

    2002 Escalade engine knock/tap?

    Yeah it does up with RPM. Idle it’s a touch over 40. I just meant solid in that it should be ok, it’s not abnormally low from what I can see. Sent from my iPhone using Tapatalk

    2002 Escalade engine knock/tap?

    My Escalade’s been making this sound when it’s first started up. It’s been getting progressively worse, but goes away at high RPM. I’m thinking it could be a lifter, or maybe flexplate issues? Really hoping it’s not something more serious. Anyone know what it might be for sure? Oil pressure...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Haha yeah that was a month ago, but In MO that could mean anything from 70 to 25 and snowy. Unfortunately got option B that day. It’s been staying around 55 and rainy these days. Sent from my iPhone using Tapatalk

    Started replacing the sway bar bushings up front with energy suspension. Got part of the way through and went inside to thaw out from being in the driveway.

    Beginning rebuild on Escalade LQ9 motor

    I had the option, but would have had to pay the core charge in order to keep the old motor. I was tempted, but ultimately saved the cash to put back into the truck in other areas. Plus my garage is pretty short on space as it is.

    Beginning rebuild on Escalade LQ9 motor

    Going to go ahead and continue fixing up the Escalade. New engine runs like a champ (and actually better than the old one..) . My guess is the valves needed adjustment before one finally let go, because this engine is much smoother. Our mechanic replaced all of the engine gaskets before...

    Beginning rebuild on Escalade LQ9 motor

    Well, slight update/change of plans for this one. I still might be rebuilding this engine, but, we were able to track down a junkyard LQ9 that is getting swapped in for the foreseeable future. Engine has 50k less miles than on the old one, and I have a fairly short commute so it should last a...

    Brett's 2004 Escalade 6.0 AWD build

    Yeah, I’m kind of in the same spot with mine. I have a car already so I don’t need to tune it. BUT, it’s kinda hard to browse Summit and not want to buy speed parts. Sent from my iPhone using Tapatalk

    Brett's 2004 Escalade 6.0 AWD build

    Oh man, tough call between the Escalade upgrades and a project car. It’d be pretty sweet to get an old interceptor and make a sleeper out of it. Or LS-swapped third gen. Sent from my iPhone using Tapatalk

    Yeah, it’s wd-40 “blue flame” or something like that. Supposedly it breaks through rust better. I’m just worried about snapping the bolts off, but I’ll cross that bridge when I come to it. Sent from my iPhone using Tapatalk

    Beginning rebuild on Escalade LQ9 motor

    Trying to figure out the best way to unbolt the heads from the y pipe underneath. The bolts are pretty well seized, so I don’t think there’s going to be an easy way. Debating right now if I want to invest in a torch, or just stick a 1/2” impact gun on it and hope for the best. I soaked them...

    Definitely. I’ve seen people just hook a chain to the block/heads, but this seems like a better route. Sent from my iPhone using Tapatalk

    Beginning rebuild on Escalade LQ9 motor

    Weather is getting straight unpredictable here. 70 and sunny one day then cold and rainy the next. Haven’t been able to work on the truck much but figured I’d show my handiwork so far. I don’t think I’ve shared any pics of the outside, so here’s a couple. It’s actually a 2001.5 model...

    Nice! I think the LQ4s are more common, and can be had for a bit less from what I hear. Only difference is dished pistons instead of flat-tops. Sent from my iPhone using Tapatalk

    Beginning rebuild on Escalade LQ9 motor

    Well, hands were too nasty to take a pic on my phone, but I was able to wrestle the intake manifold out. This engine leaked from the valve cover gaskets a long time ago, and it shows. Black nasty oil on everything on top of the engine. Also was able to loosen the exhaust bolts with WD-40...

    Beginning rebuild on Escalade LQ9 motor

    Started on the top of the motor and found the culprit. Looks like a spring busted, but from what I can see the valve is still there and the clip is in place. Turned the motor over by hand and it still moves with the lifter. Any chance I won the lottery and don’t have a bent valve? Sent...

    Beginning rebuild on Escalade LQ9 motor

    Decided to o ahead and rebuild my engine. Right now I’m trying to decide if I want to hop it up while it’s going to be torn apart. Haven’t decided on L92 heads, as replacement LQ9 heads are dirt cheap and would let me keep my intake. As far as the cam goes, is there a good cam that would up...

    No compression in Cylinder 6. Worth rebuilding a 200k mile engine?

    I have a feeling it’s similar here. Most shops are $100+ an hour, and it’s a pretty big job. I’d attempt it, but I don’t have the cherry picker and other tools Sent from my iPhone using Tapatalk

    Definitely considering it. Forgot to mention, engine is a 6.0l coming out of an 2002 Escalade Sent from my iPhone using Tapatalk

    No compression in Cylinder 6. Worth rebuilding a 200k mile engine?

    Just as the title says really. Check engine light is flashing and the code is for P0306 misfire and the MAP. I’m assuming the intake valve is either stuck, bent, or dropped. Mechanic said it’ll need a new engine. Anyone think it’s worth doing on that old of a car? The cost would definitely...
