Hi folks! New member here hoping to get my first F-Type.

I have a decent budget for the car but have always heard rumors about JLR and have been reading up a bit to try and dispell them and simply learn more.

That said, I've used the search and haven't easily seen a direct comparison between the 2.0L petrol, V6 (AJ126), and V8 (AJ133) in terms of reliability. I've seen that the 2.0 petrol (ingenium) has been far more reliable than the diesel ingenium but not much comparison to the other engines. Again, specifically on the reliability aspect.

Could any of you vets provide some insight into here? Thank you.

 

I am on this forum very frequently and can't recall anything about the 4 banger except exhaust and tune questions. Nothing about engine issues.

 

Interesting. You ever hear much about the V6 or V8? Seems like the poll so far has skewed in that direction... Not sure if they keep better due to being naturally aspirated.

 

Eh?
Naturally aspirated?
ALL F-Types are forced induction!
The V6 and V8 are supercharged and the I4 is turbocharged.

 

To be clear, the AJ126 and AJ133 are forced induction engines via supercharging and are not naturally aspirated.

The main areas of concern for the V8 and the V6 variant are the plastic cooling system components, which can cause catastrophic engine damage if they fail. Early AJ133 engines had issues with water pump failure and should also be inspected for any signs of coolant loss or seepage. There are now aluminium pipes to replace the water outlet under the supercharger to eliminate that potential failure point. The plastic heater pipe between the cylinder heads at the back of the engine is another know failure point.

On both the V8 and V6 any drop in coolant level requires immediate investigation as to the cause.

Other than the coolant pipes, the AJ126 and AJ133 as fitted to the X152 appear to be robust and capable of well exceeding 250,000 km with proper maintenance.

 

Hi, I would suggest that you try the UK F Type forum as well. There are a lot of 4 potters in the UK, they will have more experience with them. Or try messaging Powerhouse who has one in his F Type.

I understood that the p300 engine did have some issues early on (from memory it was available from about 2018 in the XE). We have it in our 2019 build, 2020MY XE and have not had any issues though the car has less than 15000km on it. It is a lovely, lively engine which behaves like a little NA V8, though to be honest as a fan of engine noise, I'd rather a little v8 in it.

 

Whoops sorry my mistake!

 

Thank you for the clarification! I assume the aluminum parts you mention are all aftermarket? Or were they included stock some years in?

And was the plastic heater pipe between the cylinder heads upgradable as well?

​​​​​​Guessing like the other poster, not much has been heard from the 2.0

​​​​​​

 

Yes, the two alloy coolant cross-over pipes at the front of the engine are after-market.
The OEM plastic cross-over pipes were upgraded around 2018 from two piece (susceptible to splitting at the seams/joins) to one piece, and have proven to be reliable so far although it is early days yet.
The plastic heater pipe (aka the heater manifold) at the rear of the engine is still two piece (no one piece upgrade yet) and is still problematic, and rumour has it that the after-market is working on an alloy version.
I know nothing about the coolant pipes or heater manifold on the 2.0 I4.

 

And to add we also have a nice Aluminum replacement tube from the back of the water pump to the oil cooler brick. If changing the water pump that is an item to swap out too.
Very cheap at around $25.

We have had postings by the manufacturer of the Aluminum replacement pipes and they are considering adding to their product line.
Maybe a set for the 5.0 NA and maybe a rear water manifold replacement in Al. too?
We can only hope but the Al. front cooling tubes seem to be selling well and I am completely satisfied with the set I purchased. Not on the car yet as I had the failure prone plastic tubes replaced under warranty when they started leaking. The quality is top notch!

Holy crap! The price has dropped to $65 for both pipes with free shipping! Man I should have waited as I paid around $200+ for my set when they first came out!
Really a great deal now for sure.

The 2 litre Ingenium petrol engine appears to have issues with the supercharger mount cracking.

 

Isn't the 4-pot turbocharged?

 

It is. Apparently tech certified doesn't mean much.

 

My apologies, I did mean to type TURBOCHARGER, but was thinking about the supercharger on the AJ133.

 

You could be right, but mistakes do happen whilst typing.

 

I guess there were no codes to diagnose.

 

Hmm, so that comes to a follow up question, is this problem found with both turbo chargers and superchargers?

 

If you are talking about the turbo mount cracking and if the supercharger mount also cracks then no, there is no real equivalent on the supercharger to crack.
The supercharger is bolted down onto the intake plenums and I have never read of the join(s) cracking or leaking.
The only relatively common problem with the supercharger is the coupler / torsion isolator wearing and then rattling.

 

Yes, the turbocharger mount cracks and the entire assembly must be replaced. As @OzXFR, points out, the supercharger is bolted directly to the engine and the coupling to the drive pulley is prone to causing a rattling sound.

 

Interesting. I started diagnosing cars in 1968, but now I date myself. I sometimes have a 'senior moment' and make random comments that I must apologise for.

Thank you for pointing out the inaccuracy.
