you
00:00:07.430 00:00:07.440 hello everyone welcome back to work man
00:00:09.770 00:00:09.780 tips for another video today we've got
00:00:11.869 00:00:11.879 AC 350 on a 2013 plate which has a v6
00:00:16.400 00:00:16.410 diesel engine and this engine has a
00:00:19.370 00:00:19.380 major oil leak
00:00:20.540 00:00:20.550 now this v6 diesel engines have a common
00:00:23.570 00:00:23.580 problem where the engine oil cooler
00:00:25.490 00:00:25.500 seals wear out and they leak oil these
00:00:29.720 00:00:29.730 are what the seals look like so we're
00:00:32.659 00:00:32.669 going to be changing them today and when
00:00:35.030 00:00:35.040 I say it's a common problem I mean it's
00:00:39.709 00:00:39.719 a common problem these are all the ones
00:00:41.930 00:00:41.940 I've changed and these are like my
00:00:44.150 00:00:44.160 trophies so before I get started I'm
00:00:47.959 00:00:47.969 just gonna show you underneath the car
00:00:49.670 00:00:49.680 and what it looks like when the engine
00:00:52.220 00:00:52.230 oil cooler seals leak so once we're
00:00:55.970 00:00:55.980 underneath the car and we've removed the
00:00:57.619 00:00:57.629 rear cover we can see that there's a lot
00:01:01.939 00:01:01.949 of oil and it's mainly coming down from
00:01:06.740 00:01:06.750 the bell housing area and usually it
00:01:09.770 00:01:09.780 goes all the way across all over the
00:01:13.040 00:01:13.050 sump and it usually looks like it comes
00:01:16.669 00:01:16.679 from the gearbox area but it's actually
00:01:21.169 00:01:21.179 leaking from the oil cooler seals on top
00:01:22.999 00:01:23.009 of the engine and as you can see this
00:01:28.160 00:01:28.170 one is quite bad
00:01:30.870 00:01:30.880 so let's get started
00:01:51.540 00:01:51.550 [Music]
00:04:10.020 00:04:10.030 00:06:03.110 00:06:03.120 00:07:10.460 00:07:10.470 hello again I'm back finally we've got
00:07:14.610 00:07:14.620 the oil cooler out and we've got the new
00:07:17.040 00:07:17.050 seals in now these new seals are purple
00:07:20.190 00:07:20.200 I think they're slightly modified to
00:07:21.840 00:07:21.850 withstand the heat and the brach is all
00:07:25.650 00:07:25.660 clean ready to put the oil cooler back
00:07:28.230 00:07:28.240 on now I just wanted to show you the old
00:07:31.950 00:07:31.960 oil coolers seals you can see slightly
00:07:37.920 00:07:37.930 they're quite flat that's why don't we
00:07:41.070 00:07:41.080 leaking and finally
00:07:48.710 00:07:48.720 I'll definitely recommend to change
00:07:51.230 00:07:51.240 these inlet manifold gaskets before
00:07:55.400 00:07:55.410 putting it back on so let's get this
00:08:00.500 00:08:00.510 engine started
00:08:13.980 00:08:13.990 so the jobs all finished let's go ahead
00:08:16.900 00:08:16.910 and start the engine
00:08:35.120 00:08:35.130 so the oil cooler cells have been
00:08:37.409 00:08:37.419 changed and the engine running nicely
00:08:41.149 00:08:41.159 here are the sills and the gaskets
00:08:43.620 00:08:43.630 that's being changed oh and before I
00:08:46.500 00:08:46.510 forget add them to my collection so
