Engine block is made by "cast iron". It is not rust but a sort of passivation (like the invisible layer on stainless steel) Do not worry, cast iron is "rust-proof" Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

hiya,, we get around six or seven new land rovers a year and they are all like this,, we even get a couple new discoveries too and they are the same,, ones delivered in summer generally are better than the ones delivered in winter as the delivery lorries carrying them spray road spray and salt up onto them whilst delivering them on the motorway,,, just normal really though,,
worth noting though that we get a few toyotas too and they're just the same, just that the chassis is thicker thats all but still have some surface rust. i honestly dont get the problem people have with using old engine oil though for rust prevention,, as long as its not dripping off it is perfectly fine and as mot inspectors too i'd rather do an mot on one with engine oil coating the underside and know its looked after as apposed to one covered in mud or cow  and not be able to see brake lines, calipers and body parts etc,, and also know that far more motorist are killed every year from skidding on the latter as apposed to the former,,,,
i personally use waxoil on new vehicles and then top it up every year in the autumn by coating inside and outside the chassis with used gear oil,, it last longer than engine oil and isnt as runny  |

Not entirely correct, many years ago they did. My first 109 was delivered from factory on a zinc galvanized chassis. I don't know when they stopped that, but it is not true they never did. I guess they figured out everlasting cars are not the way to go... Never forget: cars have owner, Landrover have field service personnel. |

That's interesting as other than very special one offs, I didn't think LR ever galvanised any production chassis. I thought i read in an article that it was because of the issues it would cause for welding repairs in later life.

Then again, if a chassis was produced in an appropriate gauge/spec of steel and galvanised from day 1 - then the potential welding issue might not arise for another 70 years? At least it might have been offered as a factory supplied option for those who use their vehicle in a hostile environment (or simply want their Defender to outlive themselves).
Interesting to note how many steel car bodies are now pressed from galvanised sheet and then welded together without too much of a problem. I remember the days when cars would have rusty panels within 2 years of manufacture - now steel bodied cars go to the crusher after many years service with little sign of severe body corrosion. |

I remember some years ago looking at a Mercedes G Wagon on a dealer forecourt and noticed the chassis looked as good as new even after several years, the black paint / coating was still 100% in tact with no sign of rusting on the welded seams.

I galvanised the chassis on my 86in Series 1 25 years ago and its still in great condition even after being used in all conditions.

Regardless of delivery condition it's a good idea to get any new Defender's chassis protected ASAP. I've juts had mine Dinitrolled by Auto Wax Works and I'm very happy with the result.

I'd say it is rust ok it also works as a passivation coating. Don't worry though an engine block won't rust to the extent it's a problem. It would probably last 100 years and the oil leaks will have started long before then. I recently acquired a Perkins Diesel made in China and was surprised to see all bits that might rust are either painted or varnished. No rust anywhere. Ford just can't be bothered on their engines. No real issue from this it just looks a bit naff. |
