I'll bore on, (hope you can all take it again
) so here's just a couple of experiences regarding oil,and filter changes, and flush outs with flushing oil.
Bought the Mk1 2.4 XK engined Jag in about 1965, drained and flushed the motor, the ends started rattling!
:Old fashioned oil,had been it's 'life blood' which wasn't a patch on the modern stuff?
Can't possibly count the number of oil and filter changes I've done, but suffice it to say owned more cars privately than I care to remember, and have worked at RR, Jaguar, Rover, Volvo, Ford, Vauxhall franchises in years past, to name just a few, as a workshop technician, and attended factory courses for most of those vehicles,.....all years past now.
To the present time.
Her indoors chose a small hatch with about 8k on the clock, and the suppliers assured me it would have a full service, including the engine oil and filter change. Before we decided on the particular vehicle, I insisted on having a good look at it's underside up on their Bradbury type four poster hoist. Everything looked spot on, and the filter appeared to be newly fitted.
However about four days after acquiring the vehicle, it developed what was obviously to me anyway, a cam follower/valve train rattle at start up. So, I checked the dipstick and....... the oil was up to the mark, but with traces of mayonnaise on its tip, and also a little of the same deposited on the underside of oil filler cap fitted to the rocker box cover.
I changed the oil and filter twice over a two week period, cured the rattle, and now the oil has remained pretty clean, with no deposits of at all. She is now due for another oil an filter change, (today's the day
) but after 3k miles since the last one the oil is just dark brownish, no rattles and no deposits. Almost 16k total on the clock.
So, I can only guess. Oil initially at PD service sucked out via the dipstick tube, leaving old oil in the sump, and the filter was????
Erm' she runs as sweet as a nut now, and the plastic bowl, ratchet, socket, tourniquet, funnel, 4litres of Magnatec, are sitting at the ready for me to get my soft old hands dirty again!
PS I do nowadays wear a pair of latex gloves. How
is this for an old git' nudging 70?
PPS I know, the mayonnaise may of been caused by short, cold runs, but even so??
