Carlton 2.3 Turbo diesel - Alyn Beattie
Hi All

I have to change the oil pipes running to the oil cooler on my 1993 Carlton diesel.

I am considering using an engine flush and then changing over to Millers engine oil as recommended by HJ.

As the car has done 150,000 miles will I be wasting my time or will there be some benefit?

By the way the two pipes running to the cooler from the flexible pipes just under the radiator cost £67. Dear or what?

I don't like some prices charged by car makers, but are these really expensive for pipes which have been operating reliably for 150,000 miles carrying hot, high pressure oil, and subject to vibration etc.? the engine depends on them.

If you have the end fittings, see what your local hydraulic specialist would charge, but make sure he knows what the duty cycle is!

Regards

Be a bit careful about flushing. On old engines it can dislodge all the accumulated sludge that is actually doing some good with the sealing, and may go on to block oilways.

Spectacularly good advice from John and Dave. Dave highlights the problem of switching an old high performance engine over to fully synthetic. It works as a very effective flush and you have to change it several times before it stops finding bits of old rubbish in the oilways. And your reward may be weeping oil seals.

Thank you all for your comments and help

I am slightly confused. I realise the use of fully synthetic oil on and old engine could cause problems, but did not think the semi synthetic acted in the same way (I believe the Millers oil to be semi synthetic). Perhaps someone could enlighten me as to the diffrence between fully and semi synthetic and their usesAlyn Beattie wrote:
