• Vauxhall Corsa C - Corsa C 1.2 16V - engine noise 9 Oct 2014 (Forum)
  The light and the noise both happen if the car is revved high when not diving, just sitting on the drive. Sometimes I can turn the engine off when the noise is happening and the oil light is on then restart it 30/60 seconds later and the noise isn't there and the light is out. I've changed the timing chain etc but recently had to have it all off again because the water pump had to be changed and when it was removed there was rubber from the timing chain cover gasket mangled up in the pump!!
• mazda 6 2.2 sport - madza 6 engine failure under warranty 30 Dec 2020 (Forum)
  He dropped the sump to find the oil strainer blocked with carbon sludge and steel filings. The filings are from some major bearings somewhere in the engine. So what's the cause and who's fault is it? Either the injectors are leaking fuel into the engine, which in turn is mixing with the oil and changing the properties of the oil, it normally acts as a lubricant but also cools the engine.

• Primera 1.6Si R reg (P11?) - service 22 Mar 2004 (Forum)
  Quite a lot of rust has appeared on bolts and screws and the like and a little on the engine. Would the oil flush and change assist in inhibiting corrosion? Would cooling systemm flush and change help inhinit corrosion? I know the best thing would be to actually drive it but I can't afford all the tax etc just now.

• Citroen Xsara Picasso 2003 Auto - Changing down, auto gearbox problem 27 May 2011 (Forum)
  When changing down the gear box has a latency; when the revs drop there is a degree of  hesitation then it bangs into the next gear in the most abrupt manner. My dealer said it was because the gear box oil had not been changed and I took it back to him twice in six months for him to try that solution, nothing happened, it's still awful.
• Ford Mondeo III (2000 - 2007) - 02 2.0 tdci fuel filter change 14 Oct 2009 (Forum)
  hi all, ive never change a fuel filter on a diesel, do i need to fill the thing with diesel first? if so is it via the 'in' nozzle on the filter? Also where is the oil filter and washer pump on ths car, i want to change all filters but the washer has packed up, though the wipers still work so im guessing its not a broken fuse!
• Volvo S90 - Oil dilution/DPF 23 Jul 2023 (Forum)
  My friend purchased a used Volvo on an approved used scheme "Volvo Select".  Within 30 days an oil level warning light came on stating that the oil level is to high and requires adjustments.  This has happened on 4 occasions and each time Volvo has recommended an oil change.  No solution to the problem has been found.
• Vauxhall Vectra C - Vectra C 1.8 (2003) - Using wrong oil, fault codes 20 Oct 2014 (Forum)
  In addition to these codes, idling is surging. I have now purchased enough 5w30 fully syntehtic for a complete oil change but am unsure as to whether there is anything else I should do?
• Ford Escort (1993 - 2000) - 93 1.4 oil in air filter 14 Aug 2008 (Forum)
  not really sure if that correct its got a twin choke webber on thanks in advance jas just seen this would this apply If the crank was hitting the oil you'd hear it - and the oil froth would be sucked up the breather. You'd be getting periods of loud pinking and a cloud of smoke bigger than the Torrey Canyon. [Now that'll date you...]
• Changing a head gasket 14 Jan 2003 (Forum)
  However, reading the Haynes manual there's no mention of changing them - should I or not? Also, is it worth doing anything else, like changing the valve stem oil seals, whilst the head is off? And finally, is it possible to tell if the head needs skimming without any special measuring tools?
• Second hand car warranty - oil leak 7 Sep 2025 (Forum)
  I had to buy remotely, so asked him to confirm that car had no issues - which he did.  3 weeks in, I gave car for a service and to change cambelt. Mechanic called to say that there is a 'big' leak of oil. Turns out was from the rocker cover. He said would fix for £100 as already all opened up. Car was sold with 6 month engine and gearbox warranty, so I contacted seller.
• Volkswagen Sharan - VW Sharan DSG oil/flywheel 27 Mar 2018 (Forum)
  I've read lots of what appear to be conflicting reports over this engine.  Does it have a wet clutch?  None of the auto boxes I've looked at have had the dsg oil changed even with dealer history but yet, I've seen on a couple of sites reports that suggest it is wet.  Assuming it's the same engine as in other cars? Also given its an auto will it have a DMF still or does it use a torque converter.
• Ford Focus 2004 1.8 Diesel - replacing crankshaft pulley and seal after oilleak 30 Sep 2014 (Forum)
  Hi All, My Focus got an oil leak and my father-in-law located the problem as the crankshaft pulley. He changed the seal twice to no avail, then replaced the pulley and then another seal in the new pulley. Each time he has replaced the seal or pulley the oil leak has returned...
• Peugeot 306 (1993 - 2001) - Electronic oil-level gauge 30 Nov 2008 (Forum)
  Mine has behaved itself pretty well for 9 years, but it is now showing signs of reading low. That doesn't matter much to me, as I always check the dipstick and I am 99.99% sure that the oil will be on the top mark, as the engine uses none between changes. The problem is that on the rare occasion that the car goes in for treatment, the technician 'tops it up' with the result that the level gets too high, and I start to worry about gasket failure.
