Default Why Was the AJ6 2.9L Unreliable?

Can anyone tell me Why the AJ6 2.9 SOHC engine was unreliable please?
They have a V12 head on them and V12's were reliable. Cheers

As for myself, I have never seen one. Not saying they are unusual, I just haven't seen one. You would probably be best starting your own thread, or searching this forum, something like "2.9 head problems"
If you haven't done so, please go to the new member section and introduce yourself. Welcome and good luck.

I ran a 2.9 for a number of years, can’t say it was unreliable, a bit under powered but when I eventually sent it to the scrap dealers i had pulled he engine out for scrap value and I could still see hatch marks in the bores, 200,xxxx+ kilometers IIRC.
What makes you think they are unreliable?

Hi Susdev,

Welcome to the Jaguar Forums! It's great to have you with us.

I have moved your post and the replies to start your own thread, since the thread you posted to was on an unrelated topic.

As far as I know, no Jaguars with the 2.9L were delivered in the U.S.A., so you're more likely to hear from owners in the U.K., Australia and other countries that had that option.

In the meantime, please visit the New Member Area - Intro a MUST, and post an introduction so we can learn something about you and give you a proper welcome.

Cheers,

Don
