New lfx engine

[Evergreen6]

Replacing the engine while the car is in lease might open you up to additional liability or specific requirements for engine replacement as part of the lease terms. I'd read the agreement carefully. I'd be more apt to hand the dealer the keys, pay the losses, and let them deal with the repairs.

Big lesson learned, eh?

U just take off the parts and sell them? Well that's what I was planning Anways.this was my first car I was paying for myself and it went horribly 😔, I'll go speak to the dealer I suppose and see what my options are, I might just let them fix it, I was asking for engine replacement as a worst case scenario, and yes. Many lessons learned.

Good used LLT engine is $1500 range. You will have a heck of a time swapping in a LFX which requires the Deplhi ECU and harness vs the Bosch LLT unit.

Also, there are no plug wires on the LLT or LFX engines...they have coil on plug configuration.

You sound young. Not a bad thing. But in this kind of situation where it could potentially cost you a lot of money to get OUT of the car, I'd highly suggest taking someone with you when you're talking about what needs to be done and how much it's going to cost, and what the options are. It's good to be independent and learn things, and pay for it all yourself, but it's smart to be equipped with people who have more experience who can help you avoid bigger mistakes. Just my $0.02. Good luck man.

Good advice here.

Live and learn, personally I have never heard of modding a leased car that much, especially tuning one. I think that is where they got you on not covering the warranty, which makes sense really. Good luck with the whole situation!!

So why do you think the engine is bad anyways? A head gasket on most cars does not require a new engine, except for those pesky northstar POS engines.

And finding oil in the coolant is not usually indicative of a head gasket, but rather a leak within the radiator from the oil cooler... Don't go blowing money on an engine when you must need coils or an ECM. Can you revert the tune to normal? It's always possible that's the problem, or even some faulty wires.

Did you check compression? If it's good I wouldn't suspect internal engine problems, though misfiring and running hot can ruin the engine. If it's been overheated after that cooling system problem then of course it could have a head gasket problem. Get a chemical block test from NAPA or something if you know how to do it... Check the oil for water, not the water for oil.


Also did they decline fixing the radiator hose popping off? If the tune didn't cause the overheating problem, but the defective hose or clamp did and it was never modified... it should still be under warranty. They have to prove it was related to the tune, and cooling systems are hardly touched when modding except for low temp thermostats which I don't think you changed.

first thing I'd do is get the stock tune put back on.

sounds like you might have some overheating issue... might be related to tune or something else. you could just have a coolant leak somewhere.

I have found 13' LFX used engines with less that 10k for $1200 shipped to my door.

Lets start from the begining........ there is absolutely no indication that you need a new engine so don't make your decision to give the car back and take a $6,000 loss because of an assumption. Troubleshoot and find out what the problem is then decide.

Yeah, if I was going to replace an engine I would get a low mileage used engine. Reman is probably an option too considering how common the LXF engine is.

Keep in mind that he leased this car. That means he only paid to use it for so many years/miles. When he returns it, it needs to be worth the agreed upon value at the time of lease. A car with a used/replaced engine is not what the dealership will be expecting come end of lease. It will hurt the resale value of that car, and they'll expect him to cough up the difference or buy the car.

I would fix the engine that's already in it. I think the dealership is trying to rip him off instead of fixing the car.

First off I just wanna say thanks for the all the input and advice, I really appreciate it. And the facotry tune is on, the dealer said they tested for hydro carbon? And said it was fine. But I can smell antifreeze in the cabin. And this whole issue started when I first got the car. From nov of 2013 till about January or feb they couldn't figure out what was wrong. Then eventually they realzied there was tsb out for the misfire under accerlstion. So got that fixed. Started modding skip to December of 2014 car was working fine. Had all my mods installed. day before Christmas Eve I get on and start my car n get a service stabitrak n it starts sounding werid. Like sometbing is clogged. I ask go around asking ppl bc I think it's my hi flo cats and everybody tells me no can't be. I take of my manifold spacer bc people r saying it could cause a vaccume leak. Doesn't fix the issue. I finally get a scanner and realzir cylinder 6 is misfiring. ( worst mistake here) people tell me it's bc of the cold. So I let it be. It goes away and comes back mid march, I start hearing a loud rattle and cyl1-6 misfire. And normally my coolant temp is 180 and same with my oil temp. Now it doesn't go below 195. And if I let it idle it'll rise upto 220. I tske off my hi flo cats bc I started getting readings for a low 02 sensor. And realzied they got clogged. I ship them back to solo and they tell me the cats r complety torched. After the cats were taking off the car only misfired on cyl 2,4,6. So on the Same bank, rn mostly it's only on 2,6. Very little on cyl 4. And I get the service stabitrak light. I have the facotry tune on it and factory cats

Edit: just checked my oil dipstick. Seems a little to dry,I don't see anything leaking but dryer than it's been in the past. I just got an oil chnage maybe less than 500 miles ago

Moe, you are in NY. There has to be a shop or dealer that can figure out your problem. I would ask around, check with the local Camaro club and get the car in the right hands. Someone can fix it and most likely without a new engine. Good luck.

Find a good independent mechanic to properly asses the condition of the engine. Maybe there is a reasonably inexpensive fix to the problem. Good luck.
