Thorneys latest on oil pumps
Discussion
I've just watched Thorneys latest vid on Facebook about the oil pumps and wanted to see if this was a very rare issue being highlighted or something becoming more common? And as such how many are considering replacing theirs with the uprated version just in case - albeit a 3k job?
When I ran TVRs the S6 could fail due tot he bottom end bearing lunching itself (as I found out to my cost) and it soon became an upgrade of choice for a number of owners to swap to an uprated one to avoid a costly rebuild - is it going to become similar with these oil pumps?

I took it as a bit of a scare story.
He mentioned 3 failures in the last 2 months.
He's been looking after hundreds of McLarens for years and has only mentioned this now.
Hope I haven't jinxed myself
I took as a heads-up as a reason that oil pumps could be excluded from the Thorney warranty if a failure occurs. If my memory is working correctly, I recall that there isn’t a written Thorney warranty. All is down to a unilateral decision by JT if a failure would be covered. That was a while ago, so there may now be a formal document? He mentioned 3 failures in the last 2 months.

At £3K a failure, thats gonna hurt the bottom line.
If the oil pump goes it ll probably be a minimum of 10 times the cost of a £3k pump with damage to the engine.
Thorney replied to a comment on the warranty question on the video stating it would be wear and tear - so seemingly suggesting it would not covered, nor the damage as a result.

I agree on that - it's more a do we chance it (first I guess many of us have heard of the issue) or do we pay 3k or so and alleviate any potential worry. Im in for a service in Oct at Renn Works so will have a chat with Sam about itThorney replied to a comment on the warranty question on the video stating it would be wear and tear - so seemingly suggesting it would not covered, nor the damage as a result.

Their website specifically mentions that there is still no formal warranty document.At £3K a failure, thats gonna hurt the bottom line.

If McLaren have improved the part and I guess that says something.[quote=TTB] And as such how many are considering replacing theirs with the uprated version just in case - albeit a 3k job?
To answer your question, I intend to talk to John and subject to there being some material (no pun) improvement in the pump shaft / needle bearing design, then I will get the upgraded pump.
Some research and images of pumps that were inspected during engine builds shows the original pump shaft and needle roller bearing design is marginal.
As usual imo, Thorney are ahead of the curve and the scope of their capabilities has drawn the failures to their premises for resolution. John shares all this stuff for precious little thanks sometimes it seems.
With engineering failures, prevention is better than cure.
I could not care less about warranty, but I used them to PPI my 650S and was super impressed.
