80 series big end change

A tale of disaster averted?
A friend recently bought his first 1HDT 80 series (1994 UK model) and
while discussing what he should do to it the subject of big end bearings
came up. I've been meaning to do something about our two for about 5
years but finally got round to doing something about it!
My friends 80 went first (115K miles) and the bearings were like new, I
suspect a previous owner must have changed them. Then my 1994 went in
(approx 150K miles) and it looks like lady luck was smiling at me for
while now because one of the bearings was in a very bad way and all of
them were covered in surface spots that I suspect are a precursor to
delaminating.
A picture of the bad bearing:

The crank is surprisingly in perfect condition so all that damage must
be tiny particles slowly coming away.
Our 1993 HDJ80 is next, probably next week so I'll update you all with
the results of that one.
Jon.

John,
When I did the bearings at 130k they looked a bit scratched and
discoloured but yours are looking real bad. Tha's lady luck indeed!

Hi All

Thanks for all the advice and Julian that is a very tempting offer. I will look into the oil consumption issue later as I understand it is not terminal, yet! Reno has an interesting idea about having a go ourselves and I would hope that I can manage to do this. I have read that using this plastigauge ensures that the correct bearings are used and I will research this in more detail. If you look at the Aussie websites Mr T has coughed up at least some of the readies to have this fixed but I think my baby is too old to try the warranty claim??

Re new types of oils I am still using the stuff halfrauds sell so its not that and I change the oil/filter twice a year irrespective of mileage.

Sorry for not being very verbose but I am struggling with this mail on a rubbish old laptop at home as Faith has got the decent laptop with her. I shall revisit this in the morning.

All the best

Simon

When I looked into this a couple of years ago Halfords fully synthetic
wasn't a suitable composition for the 1HD-T bearings, but their semi
synthetic was close (high calcium, no or very low magnesium etc.). Of
course, they may have changed this since.
The best advice has to be to check your big end bearings even if you have no
symptoms - if you wait until you know there's a problem it will be a very
expensive one.
I checked mine about 6 years / 60k miles ago and will be doing so again
shortly. They were fine when first checked, the car had 178,000 miles on it
then, so they probably weren't original.
Hope this helps,
Toby

Warm idle is a little off the bottom, Warm >2000rpm is just over 1/3
Seriously hot idle shows zero!

Well chaps, am I glad I don't have an oil pressure gauge !
After I posted a query on the lcool site about the use of Chevron
Supreme fully synthetic a while ago, some folks like my old mate
Craig were very helpful in highlighting the difference in
US/European/Jap oil composition and engine design. The Chevron oil in
question is made in Europe to Euro spec which is much closer to Jap
than US spec. The mineral levels being quite comparable.
So as soon as I got back last week I bought the Chevron from COSTCO
at 11.73 for 4 litres and put 9.6 litres in the old girl with a new
Mann filter. (An oil that meets the spec of the engine, but which is
not at the higher spec required for some recent engine designs). Its
been running on synthetic for 4 years now so I don't expect to see
any difference in performance or fuel consumption. Its the cheapest
synthetic I have seen in the country. Halfords prices frightened me,
but you can get Duckhams basic synthetic at about 17 quid for 5l in
some independent motor shops (both the petrol and diesel versions of the oil).
