marcus 0 Posted August 25, 2020 I checked the oil in my xf ute and there is a small amount of petrol, the car has 120k and has been sitting for 18 months. Does anyone know how to fix it? Share this post Link to post Share on other sites

marcus 0 Posted August 26, 2020 It might be, I still have not got the engine running smoothly. It seems to be ok but that might be the issue. Share this post Link to post Share on other sites
deankxf 20,287 Posted August 26, 2020 fuel pumps can leak fuel into the oil.. i THINK.. (not sure on the ford ones, but other makes can do it) @SPArKy_Dave may know if it's possible on the falcon one. how do you know it's a "small amount" it will mix in so you'd only be able to smell it or the oil level rise?

marcus 0 Posted August 26, 2020 @deankdxMy oil level does not rise noticeably but I can smell it on the dipstick. I was talking to a mate the other day and he said it could be the fuel pump leaking, apparently its really common. Share this post Link to post Share on other sites

Mr Polson 10,214 Posted August 26, 2020 [mention=291]deankdx[/mention]do you know what exact pump i need to buy?This one should do the job - may need to swap the fittings to the one from your current pump.https://www.repco.com.au/en/parts-service/fuel-ignition-exhaust/fuel-pumps/fuelmiser-fuel-pump-external-mechanical-fpm-008/p/A7063628 1 deankxf reacted to this Share this post Link to post Share on other sites

gerg 10,871 Posted August 26, 2020 In my experience, the oil just gets that smell about it (to an extent), especially if doing short trips and in winter. This is due to the fuel not vapourising properly in the cold weather in a cold engine, causing the fuel to stick to the bores and wash down into the oil below the pistons. Carby cars run a bit richer and can go out of tune over time, so maybe the carby needs looking at. If you take it on a good high-speed run (I'm talking a few hundred km), the oil level might drop a bit. That's the fuel evaporating out of it (not the engine suddenly "using oil" as many seem to think).Best way to tell if the oil is being diluted excessively is to rub a bit between your fingers. If it feels slimy and smooth, then it's doing its job. If you can feel your fingerprints grinding as you rub them together, then the oil has thinned or broken down, and should be replaced.Yes mechanical fuel pumps can fail in the diaphragm and pump fuel into the sump, but this doesn't happen very often.

Defective 1,692 Posted September 2, 2020 I checked the oil in my xf ute and there is a small amount of petrol, the car has 120k and has been sitting for 18 months. Does anyone know how to fix it?Add more petrol. You no longer have a small amount of petrol in there, you have a large amount. Thank me later. Share this post Link to post Share on other sites
