Oil starvation.......

[Boot Hill Bandit]

Seems like history is about to repeat itself with the ZT.........the ZS needed an engine change and now possibly the ZT

Right a brief insight......

Bought the ZT190+ a few weeks back from Paradroid in Wigan..........I knew it had a coolant issue which seems to be going away now through constant use but unfortunately an engine problem seems to be popping up.

When I went to buy it the car had already been driven so pointless checking the oil level. When I got her home and over the next few days I checked the oil level to find it didn't even register on the dipstick!

Topping it up took 1.25 to 1.5 litres........and this level has remained for a few weeks now unchanged

Twice this week I have started the car up to hear the tappets tapping damn loudly but upon driving any reasonable distance for a few minutes this goes away.

This says to me 'oil pressure problem' but I am no expert just making an observation. I note that in the receipts I collected with her when I bought her the belts have all been changed along with all the tappets, camshaft oil seals and thermostat between 11/11/09 and 19/01/10

Now I am in a quandry...........do I change the oil pump, cambelt and tensioners, crankshaft oil seal, cylinder heads or tappets again........

or do I change the engine? I have been offered to hand in my ZS and have my engine changed on the ZT with some money thrown in......

Argh!!!! what you all think???

I know I am new here but I would really appreciate your help or advice peeps........been through it all with the ZS before and it isn't nice.

I know you say you have topped the oil up but when you check it now is it black and old looking because if so the first thing i would do is give it a full oil service then see how the noise is before considering either a engine replacement or rebuild

Also check that what you hear isn't the waste fuel vapour recycle system (I call it the 'slack tappet simulator' for good reason). All petrol models have one and it fools many new owners.

Just had a chat with the previous owner but 1 and he has said changing all the hydraulic tappets on both the front and back bank is nearly £250 in parts so he just did the front bank.

Oil problems were not apparent although he was aware of the leak between engine and gearbox (crankshaft oil seal) he said the tappets were noisy even nown again so he replaced the worst bank and easiest.....

I think the route cause of the problem is either something to do with the oil strainer in the sump and or the oil pump...........these replaced and PA03 PDV will be good to go again.

Boots, there was a bulletin regarding a damaged o ring iirc causing airated oil to enter the head resulting in noisey tappets.

ooooo can you find it fella??

Car is booked into my garage on 23rd July.........they are replacing crankshaft oil seal and are going to look at what comes out the sump..........and I am hoping they can remove the oil pump too but apparently that means taking off the cambelt hope not or this is going to turn mighty expensive!

I have this problem on my 2001 V6 auto. Does anyone have the full information MG Rover issued?

Is this the o-ring in question?

Item number 2

Here's most of the text. The practical details are discussed in various MGR forums, so do a Google.

Model/Derivative:
Rover 45, 75
No: TB0037 Issue 2
Date: 26.10.2001
Section: 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***** 168295 - 2.0 engine
25K***** 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.
This bulletin has been re-issued to include 2.5 engine number in ‘affected range’.
Action required:
• Check oil level is correct before suspecting ‘O’ ring is the cause of condition.
• Remove oil pick-up pipe as described below and Inspect ‘O’ ring to confirm cause.
• Replace ‘O’ ring as described in Detail below.

Apparently it's a simple fix once the sump is dropped.

I'd say it was Item 2 in this drawing: http://www.rimmerbros.co.uk/Item--i-GRID001706
