Working on a 2009 LMM, 100% stock. I am getting real high , (possibly erroneous?) readings for one of the egr temp sensors. Anyone experienced this before? Any ideas? Truck has cel and is throwing codes p0101 p0102 and p0113 which all have to do with the MAF. Al wiring is good to maf and I...

Picture to clarify what I believe I see take a look at this. Is this a crack? If so, what is this part?

Ok, you are probably right, but To clarify, the crack I see runs perpendicular to the place where it looks like that piece mates up to head. When the truck is running I feel like I can see the coolant purging out of the little crack and then running down to the area where you see it accumulate...

I have an '05 K3500 CC LB. When the truck gets hot, it has a fairly agressive coolant leak towards the back of the driver's side of the engine. I powerwashed it and got underneath it and was able to take come pics. I believe I am seeing a crack in a metal part down there, but I don't know...

yes, this is the military version so no restrictionswitch. The filter is new and I took a look at filter mount on the firewall and it looks good, no cracked or dried out parts. Maybe try switching out my lift pump? Any other suspect places to look or ideas where/how I am getting air in?

I have the sensor mounted in the passenger side head in the rear cross over block off plate. Yes, I was always under the impression that the pass side ran hotter and that's why I put the sensor there.... I was surprised to read handcannons comment that his pass side on his truck would read...

Interesting, I suppose my factory sensor could be weak and that could explain part or all of the reason for the big difference. I suppose one of the main things to be garnered from my observations are to make sure your sensor is good if you are relying on just the factory gauge....

I installed an auxiliary ISSPRO water temp gauge in my truck. Some people thought it was stupid and asked my what the point was considering there is a factory gauge that does the same thing. Well for one thing, I live in the US, but my truck has the non-US instruments so its nice to have the...

I have a very stubborn 6.2 CUCV I'm working on and need some help. Already replaced the INJECTOR PUMP and NO DIFFERENCE. So here's what it does.... It has a strange condition I haven't seen much on these 6.2 CUCV's over the past few years of working with these. It truly has me stumped. Glow...

Dka, I know, WAY to many parts. And way way too much $, but you know how it goes...... Plus I've been doing this long enough to know to completely avoid any Chinese/low quality (dorman, etc) replacement part, so I've only bought the good stuff. I've tried cutting corners and saving money on the...

I just installed the Kennedy Hi-Pop hi-flow units he sells on his website. I think they are set at 2200 and they are Delphi units he sets up custom. I have the job finished up but am waiting on a couple other parts such as a new IAT before I put the truck back on the road so I haven't driven on...

I also had a recent poor experience with walking j. Took 3+weeks to get ftb mod parts and very poor communication.

I hear ya, my impression is that the ATT is a well purposed, easy to install, and properly supported aftermarket option to replace/upgrade the GMX turbos with something more capable for the 6.5TD. It makes sense for me as a DIY'r with limited time looking for a practical option that won't take...

I've dealt with badger a lot over the years. Fred is a good guy. But he will even tell you straight up , you get what you pay for. If you are ever unhappy with something you buy from him he will handle it. But with injectors, after I take my whole upper eng apart, install injectors (or a pump...

I'm surely going in one direction or another- I'm finishing a few other housekeeping, main't and upgrades such as Kennedy injectors at the moment. But once I'm done getting everything all dialed in the turbo is next. Tough decision, seems like really I'd see such an improvement with any of the...

racedaymechanic-- overall would you recommend the HX35 or HX40 for us suburban/tahoe guys? If we don't tow heavy very much what would be the better bet? What wakes the 6.5 up more for around town driving and overall best acceleration? I assume the 35 due to faster spool, but you mention the...

THANKS Wow, thanks, incredibly useful, relevant comments, esp Warwagon who is obviously in a unique position to comment on all this having run both. Awesome that you have done this and share with all of us your findings. Much appreciated. Both turbos obviously make sense and will offer nice...

TTS is a great website for learning all kinds of great stuff about upgrading the 6.5- fairly new to the site but really enjoying my time here. Question for those of you who might be interested, knowledgable, experienced, or simply opinionated in this area.... What do you all think of putting...

No, no, I did NOT mean it that way AT ALL! I have had 20 minute jobs turn into 4 hour jobs. Also, I have kids, etc, i KNOW how it goes. Please don't take it personally. It was NOT intended like that and I truly apologize if there was any disrespect. :nonod: The intention of my comment was...

I hear ya raceday. I think this tread is effectively making some huge deal out of what is really 30 minutes of easy work. I did the mod since I had the intake manifold off anyway to do injectors. It's a $40 kit and I spent maybe an extra 45 minutes max adding this to the total job and that...
