Was just thinking today, would it be possible to slap a oil cooler, like the one used on an MGB could be attached to a landcrab engine?

Interesting read  I always wondered why the B had one, but not the crab or most other BMC/BL cars. -Andrew |

Well, at least with the oils of the early 70s the 1800 S could have done with one, as the oil got too thin on continuous high speed cruising on Germany's Autobahns as my father found out (with a broken engine as a result). But who's gonna keep an S at full throttle for long times these days?

Well.....  IMO every car should be capable of the odd burst of full throttle - and the 1800 S really can shift if the carbs and distributor settings are spot on. But based on my father's early experience (the car bought from new and less than a year old then), I'd stay away from keeping the 1800 flat out for a longer stretch without oil pressure gauge - although I think the higher thermal stability of modern oils will avoid such trouble (even a mineral up to ACEA A3/B3 should be fine). From any car made from the 70s on, I'd expect it to be able to be run flat out for hour and hour - if it doesn't it is either crap or broken in some way. The other half's VP 1300 automatic ends up being driven close to flat out most of the time anyway when taken out to journeys - at least during the transfer parts on the motorway to the ferry or so (with 4up and all the baggage in the car it will not be that fast anyway). Even our K-engined Rover 416 Tourer does take such treatment within it's stride despite the claimed fragility of the engine (hohum....). Back to the question: I once stripped a Maxi that had an original BL ST oil cooler fitted - the owner was often towing heavy trialers and claimed it did really help. Regards, Alexander |

I'll be doing a 750 mile round trip to Cornwall and back this weekend in Eugenie, so it'll be motorway speeds for about 5 hours of the 7 involved. She did it quite happily in the summer, so I'm not worried about a fast long cruise.
Being the Wolseley, she does have a pressure guage, but it is the notoriously inaccurate electric one. I tend to look at it from the point of view that if the needle moves, I've got oil pressure.......
Chris.

Fast travel in itself was never a problem with the 1800 S. Back in the day the typical speed my father used it was between 85 and 95 mph - and even now when I'm at the wheel I find myself creeping up to 85mph when not actively watching the speed, it seems to be the natural cruising speed for the 1800 S. Remember, when it was new it was a fast (and here in Germany very expensive) car and it was also possible to drive fast due to low traffic volumes. But quite a few owners of UK built cars soon found out, that they were not designed to be run flat out for long periods, as they suffered from more failures than comparable German cars - damaged main bearings and/or crankshaft was very typical.
Chris, I know what you mean about the electric pressure gauges, the 3 litre has one. But as long as I can see a difference between hot and cold oil I'm happy (although with fresh semi-synthetic 10W40 in there it is not much now).
Regards,
Alexander

Above on this thread a excerpt from a book about oil coolers for Landcrabs was posted. I don't think the link works any more and I'd like to understand why we don't want an oil cooler on our cars. I have them on most my other cars.
Any thoughts or now how to find the article?

Mine has an oil cooler.
I was talking last year to some gentlemen who have an 18/85 which they had taken all over Europe on long distance rally events over the last couple of decades. They said they never felt the need for one and thought the car's standard cooling system fine for their needs.

I can't get the link to work any longer but I believe that an oil cooler is essential if you use a sump guard as this restricts the cooling of the oil in the sump (gearbox) and the airflow around the engine. Of course you need to consider the local climate where the car is run. The position of the 1800 radiator means that the engine is apparently better cooled than in the MGB where it is bathed in hot air from the radiator. The downside to the oil cooler is the risk of leakage and loss of oil pressure. Personally I would opt to use one in a hot climate or for high speed rallying. Regards David Mine has an oil cooler.

David,
That makes sense for my car then, as when I bought it there was a sumpguard (since removed and due to appear on another landcrab soon).
Didn't the Australian cars have a sumpguard as standard and no oil cooler?

Nick You are correct the Oz cars were fitted with sump guards as standard and had lower ratio final drives and parts of the country are sub tropical. They didn't have oil coolers, didn't blow up their engines like early British cars (dipstick) but the Mk11 Oz cars had SU needles as standard that were very similar in profile to the rich needle used in the UK so would have in theory run a bit cooler at the expense of fuel consumption. A lot of conflicting information; the key is to be able to measure oil pressure and oil temperature to be really certain. regards David If I had an oil cooler fitted I think I would also fit a very loud alarm that warned of pressure drop as a leak here can destroy an engine as has happened in rallies.
