Ernest Posted October 22, 2021 Report Share Posted October 22, 2021 Hi Just back from a lovely 30 mile blast through countryside of North Kent. The 6 went really well! But.....when home I lifted the bonnt to find that oil had been sprayed over much of the underboont area. It was on both sides of the engine bay and I am thinking that if an head gasket it would more lile be only on one side. So I am assuming that any leak is coming from the crank-case. Any ideas/sugstions would be welome. If crank-case does this involve a lot ofwork? I checked the sump oil level and this indicates level still high.

Hawk Posted October 22, 2021 Report Share Posted October 22, 2021 Some pics would be helpful if you can? Not oil related but potentially relevant .... I had a small weep from my water pump that was distributed all over the bonnet by the fan. I was losing no (noticeable) amounts of coolant and as such it took me ages to trace - particularly as it only weeped when hot! Quote Link to post Share on other sites
Ernest Posted October 22, 2021 Author Report Share Posted October 22, 2021 Thanks for responses so far. I have cleaned all the oil off, so pics not much use now - it was definitely oil Not sure what a'flame-trap' is ntc ? Best Wishes Ernest Quote Link to post Share on other sites

Bluestone Posted October 22, 2021 Report Share Posted October 22, 2021 Maybe worth looking in and around the following: dip stick aperture distributor pedestal / seal oil pressure sender / pipework for pressure gauge rocker cover (pin hole) oil cooler pipes from filter (if fitted) Ray Quote Link to post Share on other sites
Ernest Posted October 22, 2021 Author Report Share Posted October 22, 2021 Thanks Ray aand Stuart It looks like I need to take a close look at all oil-related joints (it does have a oil-cooler Ray) and see if i can idetify the cause - now, thanks to Stuart, I can identify the position of the 'flame-trap' this does look like a possible contender as the underside of the bonnet was liberally sprayed with oil.

Ernest Forgot to add check the oil trap also in the rocker cover if std and find the part number for that Quote Link to post Share on other sites
Mike C Posted October 22, 2021 Report Share Posted October 22, 2021 If the fan has oil on it I'd check the rocker cover gasket, starting with the hold down bolts- they only need a small amount of torque but they can't be loose. Quote Link to post Share on other sites
Ernest Posted October 23, 2021 Author Report Share Posted October 23, 2021 Thanks Mike Oddly the fan was about the only under-bonnet item with no oil on it! Ernest Quote Link to post Share on other sites

Ernest Posted October 23, 2021 Author Report Share Posted October 23, 2021 Thanks Stuart, I will have a close look next week. I am thinking that if I run the car up to warm I might be able to locate the leak more easily. I see what you mean John and I guess that your slighlty tongue in cheek observation might be correct!

roy53 Posted October 23, 2021 Report Share Posted October 23, 2021 if it has thrown oil over both sides of the engine bay then i would say it's leaking at the front near the fan. Therefor the rocker cover gasket or the front timing cover oil seal. Roy Quote Link to post Share on other sites
Ernest Posted October 23, 2021 Author Report Share Posted October 23, 2021 Yes, thanks Roy, these are both on my suspect list and I wil be taking a close look sometime next week. Ernest Quote Link to post Share on other sites
