KV6 Oil pickup O-Ring ?
My ZT190 always sounds noisy when first started from cold. Its an 02 plate and I've seen from reading threads on here that I might need a new oil pick up O-ring in the sump.
ITEM: O Ring - LYX000210L https://rimmerbros.com/Item--i-LYX000210L 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?

A tapping/knocking sound that disappears after a couple of minutes.
Sounds like its coming from the top of the engine I think.

What is the reasoning which you've read which suggests that this could be caused by an 'O' ring on the oil strainer pick-up pipe? Simon

A number of folk who know these engines inside out say it's not tappets and sounds more like mains (), however they are puzzled by the way the sound disappears so completely. I had a full belt change (including idlers & tensioners) to rule that out and also had the sump dropped and a new oil pickup pipe (with "o"ring) fitted, all with no improvement. Oil pressure (both cold and hot) is spot on. I also sent oil samples off for analysis and they came back with a clean bill of health, showing no signs of engine wear at all. All very odd. Needless to say, I'll be interested to hear if you find a resolution to your noise. Cliff Edit: I meant to add, the oil pickup pipe was considered due to a bulletin issued by MG Rover which read as follows: "TB0037 Issue 2 19.10.2001 ENGINE Title: TAPPET NOISE – AIR LEAK AT OIL PICK-UP ‘O’ RING Affected range: All vehicle with KV6 engines up to the following engine numbers: 20K摯瑬敳獩 ∗∗∗∗168295 - 2.0 engine 25K摯瑬敳獩 ∗∗∗∗168506 - 2.5 engine Description: Tappet noise on cold start or when engine idling. This condition is due to air entering the tappet oil chambers. The source of air entry is likely to be at the ‘O’ ring seal situated between the oil pick-up strainer to bearing carrier connection. This condition has been rectified from the engine change point quoted." (Thanks to RogerHeinz57 for the bulletin info)

I have a rattle on start up which is the cat (quietens down once it warms).

That depends Mike on whether "whistles" includes tensioners and idler pulleys. Were they definitely renewed?

Inconclusive perhaps but it answers the OP's question about the O ring. Regards |
