Luckily blew my engine under warranty, not sure if I would pay to replace it with a new one knowing it is an accident away from needing replacing.

Curious... can u please share more about what u mean? I've got the 2.4 myself and I'm keen to keep up-to-date with any potential or known problems??

I'm a little bit confused here.

A puma is an engine series in a defender isnt it?

are they wanting to replace a puma with an Isuzu or vice versa, or put either in a defender but calling the defender a puma?

I think the engine in my Ranger is a Puma2.2......ford product.....seems faultless in the Ranger.

fiik

Puma is a Ford engine range, including 2.2, 2.4 and 3.2. Used in both the Ranger and Transit, and flogged unmercifully all around the world. The 2.2 and 2.4 were used in Defenders when Ford owned JLR.

So I basically wrecked the top end of the engine, didn't go and see it myself as it was taken to a dealership about 5 hours away and Land Rover said given the low Km on the vehicle (just under 40 000 km) they would replace the engine.

Basically cams/followers/valves were bent/broken/had bits of metal chipped or gouged out.

Naturally as I was unhappy about the development, pushed LR pretty hard but they assured me that this wasn't a common problem, got my Defender fixed and never asked anymore questions.

Fast forward 6 or 7 years and after a dodgy mechanic or 2 had worked on my Defender resulting in it being dusted and start inquiring about a replacement motor and one supplier said obviously I was happy and hadn't destroyed an engine.

Well actually...

He claims that the tensioner on the timing chain only tensions when the engine is running the right way, which isn't a big problem in a delivery van, put it in a 4wd environment and stall the vehicle going uphill and it rolls backwards in gear the tensioner gives the chain some slack and it may jump a cog or 2.

Always been going to post here for thoughts but never have.

Cheers,

I'll be interested to hear from someone who knows more than me but it sound plausible if the tensioner is hydraulic - no oil pressure means no tension on the timing chain, engine turned backwards and the timing chain jumps. Equally, it might be false and I'm just speculating......
