Yep, Robison wrote those articles a few years ago...pretty much nailed it.

I know he posts on Dweb from time to time.

Everybody has their theories, and his writings are nothing more than that. Not sure if I buy the tooling thing or the Dex-Cool thing. So many factors involved. How an engine made ten minutes before another fails and the other doesn't can't be explained away so simply.

Simply put stay away from any rover V8 that is a higher capacity that 4.0. They suffer from dropped sleeves, cracked oil pumps, cracked blocks.

There are permanent fixes for both if you have the chips. Top hat cylinder liners installed about 2000. CNC oil pump gears a couple of hundred and you have a bullet proof engine designed to idle in the middle of the sahara all day long. I would personally throw in a good ol chevy v8 and drive issue free for a 100k+.

So, my 97 4.0 has green ethylene glycol that looks fresh. What should I do at this point, besides panic?

I'm glad someone doesn't take every word he says as gospel.

I've seen every variation of a Rover V8 block crack. If you want a Chevy motor, buy a Chevy.

Change it every two years, or whatever the interval is for green coolant.

Take it to a competent tech once a year to flush your entire cooling system, replace with distilled water and the blue BMW coolant or equivalent and replace your thermostat. Cheap insurance. Any decent equivalent coolant to tye green stuff will do but the stuff from de fatherland is just superior. Besides it has the pretty blue color that you can show off to all your friends.

Personally I've had great experience with the 4.2... plenty of high mile LWBs on the road... and yes Jimmy we know an LS swap is not in your future...but you don't know what your missing till you drive one..

Actually the 4.2 has proven to be fairly bullet proof

I dont take every word he says as gospel---that is reserved for Widener! LOL

He does have some valid points concerning the tooling and such.

every engine is susceptible to cracking but the crack ratio between the earlier rover v8s and the later ones is more than 100 to 1.
I meant no offence with the chevy comment. I hope you and no one elce took it that way. The chevy has more power, has better gas milage, is cheaper to buy and maintain and parts are available everywhere.

I take it back, I have never seen a 4.2 fail, but that doesn't really mean much as I pretty much never work on Range Rover Classics.

The tooling theory seems to make sense to me. The Brits are the first to admit they haven't done anything innovative, other than dream up creative financing transactions, in decades.

Plus the transmission, engine control kit and alternator. That is some serious coin for a 4 banger.

Here is one for $1500 bucks with 12,000 miles. Might be fun in a series or even an old Alfa spider. Not bad for a 300 lb motor.
