Ok, so we have couple things to update on. 1. they swung and missed on my oil leak with that front cover business. Put some miles on and did a trip with trailer let em check again and goes back in Friday for new oil pan and gasket as attempt #2 to figure out the oil leak. I mentioned the poly vs aluminum oil pan but looks like same type going back on. Shrug. 2. On the trip coming home with my little trailer threw codes climbing a good hill and lost power, could still maintain a little above 60 mph but like lost boost as engine had to roll much higher rpms near or at redline on anything less than flats. So credit she got me home but have new one. So they pulled codes when back and apparently there’s a bulletin and gm aware of issue but no apparent fix yet. Mass air flow related codes. After it was at home and sat for days the next start the engine light was out. So feels like normal again but just a bit of back and forth to dealer without trailer so can’t really tell. Had anyone else heard about this yet? Can anyone verify this bulletin? just under 90,000 kms now so just under 56,000 miles starting my 3/4 ton gas v8 research now lol

Ok, just got the call, 'front engine cover' is what appears to be leaking, bunch of parts/seals ordered, will be a few weeks, once that's done they can then confirm if anything else like oil pan. Since it's slow leak will be driving it until parts are in one of which is direct from usa which is the culprit to making this a few weeks away. Will take it from there and update when it's done.

Well I climbed over the engine couldn't see anything suspect, then got under front end and still nothing but peering back I could see shine off my new oil filter, so then went in under passenger side to oil filter and definitely some seepage going on that side and what appears to be below block where anything wet can be found and only one side of the oil pan looks like it gets any, and yet nothing hits the ground, a drop forming on the oil filter. And now I'm recalling my service guys said sometime ago they noticed oil pan sweating and would keep an eye on it over time, I do have the refresh power but still the older black plastic oil pan and recall hearing newer ones were coming with aluminum oil pans, so here's hoping that's what the issue is. I can't see anything higher up from this quick look at things. Will update when I know more on Thursday.

Ok boys, just went in for service and tires at 85,786 kms (53,316 miles) and tech noticed 'oil leak passenger side of engine'. I remember reading from about page 100 onward so betting it's one of these things. It goes back in Thursday for diagnosis and fix, under factory powertrain warranty to 100,000km, I do have extended to 160,000 kms (with deductible) but we're still on factory warranty. I'll update of course to add to the collective database. I just did a round trip for work that was 2516 kms or 1564 miles and average economy was 11.6 l/100km (20.3 mpg) so consistent with new (4" lift, no chin spoiler, 33x10's, 900 lbs over stock with fuel tank/tools/gear), much of that trip off pavement roads into remote mine site end of road north type trip), haven't noticed oil consumption between 5000 km oil changes but haven't really checked either and nothing is on the ground under truck when parked so must just be some visible oil the tech saw but not a big enough issue to be noticed by ground or 5000 km service intervals. I run Petro-Canada 87 octane (feels happy and quick), live at 4000' and play a lot between 2500' and 5000', and I pull a 3000 lb trailer primarily, especially since about the 50-60,000 km mark when I added a commuter vehicle, except the odd long work trip I'll take this truck without trailer for it's hwy comfort over the commuter. Any guesses to what this issue will be? Maybe we can offer a prize to the correct guess? A jr g-man badge maybe?

That was a good post. Prolly look into liability and legality stuff first! also on my light trailer with dual axle, brakes on all 4 wheels, 3000 or 3500 lb torsion axles, and brake controller keeps things smooth at left lane gtfoh speeds and stoppy like I’m empty not towing too, so just like driving an extra long empty truck, definitely set up for ‘sport towing’, if that’s even a thing? I have contemplated putting a ‘This trailer pulled by a 4-cyl...Try to keep up.’ Decal on back door of trailer.

Rule of thumb for me for comfortable towing is half the door rating. ‘Comfortable’ to me is stay with traffic, have some ability to pass. Whenever I’ve towed near limit it’s just not comfortable and feels like truck won’t hold up for continued duty with those Max loads. I read this and immediately thought 2500 or up, heavier suspension and running gear and transmissions etc, heavy towing and half tons don’t really go together. Not interested in being under speed limits or struggling so my comfort levels aren’t same as everyone’s, I stay loaded fully time and we go as many weekends as we can and live in it as we go. Even with towing the half rating I still have air bags to level properly for comfortable towing as my trailer is nose heavy and I carry weight in my box, 400 lb fuel tank just part of it. having said that we have no problem running empty no trailer speeds in any lane we want while hitched up so that’s my comfort level goals lol, we get out of town quick and can roll left lane speeds for extended periods to get out of town far enough to get past traffic and then slow down a bit for the long hauls from there

Can’t make v8 small enough for boost in half tons. Gotta be half the displacement because that’s what one turbo does for moving air, it’s like a whole bank of cylinders you can fit in your hand. I can live without the subjective attribute of sound of a v8, I was over my last 5.3 in a couple weeks, now a few years in on the turbo and smile and love the sound every day still. And it’s a stealth bomber for hunting and scouting and early morning campground polite etc. Game changer for this outdoorsman.

48,000 miles on my 22.5 2.7 HO 8spd and no issues at all. It tows almost full time now that I commute in a little maverick. 4” lift, and lots of 4wd required for primarily hunting and fishing duty. Around 900 lbs of fuel and tools and gear added to truck and low 3000 lb range on adventure built lifted alum cargo trailer.

Yes on adding 2 cylinders to the turbomax and slightly bigger turbo if needed. A manual option would be cool but 8-spd is plenty with the torque curve. Keep it long stroke, single turbo, inline. Light and simple. Just need transmission to handle the extra power. Which at 77.5hp/107.5 ft/lb per cylinder would be 465 hp and 645 ft/lbs and be the sport motor in half tons but a perfect base engine in the 3/4 and 1 tons. Boost is the future. A 6 cylinder turbomax with its 680cc jugs would be 4080cc (4.1 liter). Would need a stout transmission and running gear for that amount of torque. They nailed the output levels for the 2.7t and lighter running gear to suite half tons. That could make me waffle between motors. No NA motors in my future. Too heavy complex and loss of power at altitude. Keep the torque curve down low with long stroke big jugs.

Nice info, didn’t know about the 5 mains, but expected since it was designed as a boosted truck engine from the start. Just a gas powered diesel lol. They chose the turbo first then built the motor around it. Amazing 57mm dual volute is the equivalent of another bank of cylinders without the weight, added parts, and loss of power at elevation plus power down much lower for truck preference. And as engineers said, it can put down more axle torque in 1st gear than the old 8.1 big block 4spd did. Also, I have a problem with the Ford 2.7tt. 1. Two turbos, 2. Two banks of cylinders. 3. Square stroke. 4. Less main bearings lol. 5. It’s a multi platform design not just truck duty design. 6. It’s a Ford. kidding my commuter is a Ford maverick xl 4k tow 2.0 turbo, pulls my buddies 16’ crestliner fishing boat with ease for day trips and it’s basically a Subaru wrx baja, a rapid express sleeper and I love driving it too but not near the quiet relaxed Cadillac on the Hwy like the chev is

Expensive smiles depending on budget they may be more like grimaces lol had one for a few weeks, hauls ass and sucks gas, front end feels heavy and wallowee compared to light agile front end on the 4banger

Naturally aspirated engines lose 3% power per 1000’ elevation. Turbo motors 0.05% per 1000’. At around 5000’ the 2.7 has about 90 ft/lbs more torque at 1100 less rpm than the 5.3 and within about 5hp. Me (2.7 HO) and my hunting and fishing buddy (5.3 2014) have both and pull a few thousand lb cargo trailers set up for hunting and fishing. Sometimes we only take one rig and his comments when in mine are how quiet it is and more relaxed on hills. I usually take a few less liters on fill ups when travelling together also. 2.7 is basically the love child of the 3.0 and the 5.3. But no lifters, no heavier 10 spd as no need with the torque curve of turbo and no def fluid or emissions headaches that come with diesels. There are more wins for the turbo but those are just some key ones not to mention most reliable and lowest cost of total ownership of maybe all half ton motors period not just GM. Still smile every time I drive my truck at the effortless quiet low rpm power and when I wanna get in a hurry it’s impressive. My poor trailer does a lot of 75-80mph runs to get those lines soaking for the weekend lol and I couldn’t be happier with it. Would not go back to a na vehicle and not a diesel fan either although my trailer has two diesel heaters so I’m a fan of those. No emissions crap on those to worry about lol. I’d get over your aversion to boost and single turbo long stroke big jug inlines(cummins) as those are truck engines. The 5.3/6.2 are short stroke camaro engines. The 2.7 is the smartest choice period in half tons but especially so for higher elevation and actual truck work involved. Shots fired.

Well, we the people have been conditioned to love drama. And lots of v8 and diesel loving Americans have been salivating and creating drama around a 4 banger goes into a half ton lol...but it's been 5 years of nothing but winning as GM knew it could spell the end for their bread and butter segment. That's why it's one of only two they couldn't kill/seize in their torture testing. People were slow to realize and still a long ways to go that this is built as a gas powered diesel etc. as a long stroke truck engine. Anyway, it's nothing but drama, these things will be around a long time.

same here, my 22 refresh has been trouble free

saw a recall video for a 2023 batch of 2.7's mid-size and full size, defect in casting in the block, no online reports, guy goes from doom and gloom to rosy and back to doom and gloom, like most who try to find an issue with it...he wasn't well researched, someone can find and post here? hardest cylinder liners known to man and forged bottom end as the above link mentions etc. built like diesel...so he's like many who have been salivating for some sort of common 2.7 issue or common warranty item....poor buggers, it's been 5 years and they are still salivating for something....this block recall for free new engine had this guy just ecstatic to finally have some click bait on the 2.7 lol...anyway surely it will affect some the posters here so may as well post in the thread...found it https://www.youtube.com/watch?v=FvawXY9Who4
