KV6 Oil pickup O-Ring ?

Phil-T4 advised me that it is not that uncommon for bottom end bearings to fail. Reading on forums finds some mentions of this, with the culprit likely being not priming the oil filter after an oil change.

So does look like I need a bottom end rebuild. Which is beyond my capabilities at the moment so will cost £££.

I might get the oil tested first though, to be sure.

Sounds like your sparkly oil mystery has been solved Colin.

Stated earlier in the thread that mine sounds like a diesel on start up too but about two weeks ago changed the oil (no sparkly bits) and did a couple of long runs. Noticeably quieter, went for fully synthetic 5 - 40 (gets cold here).

Interesting thread!
I don't have the issue but for future reference does anyone have any idea how the point where the O-ring issue was corrected at the factory correlates to ZT VIN numbers?
I know that there probably isn't an accurate change point but a rough idea would be helpful in knowing if the O-ring issue is likely.
For example, the VIN on my 2002 ZT190 is 242274. I don't have the engine number.
The change over was at engine number 168506. Date?

Edit:
Hang on.....I'm paying attention now! The bulletin was issued in October 2001. So that answers my question.
I left my post in place in case anyone else missed the details.
My car was built on 17 Jan. 2002 so hopefully the affected engines were out of the system by then.

Thanks to Teflon for posting the bulletin!

I don't know for certain if this will cure the problem but I'm willing to give it a shot.

Is it easy enough to remove the sump and replace the O-ring?

Also, it looks as though there isn't a sump gasket on the KV6, rather some sealant instead? .

Looking at rimmers prices, that seems excessively expensive https://rimmerbros.com/Item--i-LVV005188

Is there an inexpensive alternative?

Did you ever get this resolved?

My own knocking noise was eventually diagnosed as piston slap. I was advised that it was more irritating than dangerous and could be safely left until it reached the point where it didn't stop after warm up (which was thought to many 10s of thousands of miles away, if it ever happened at all).

I bit the bullet though, and had it repaired anyway. Piston no. 1 was the culprit and my engine is now silent once more (well, as silent as any V6 is anyway).
