Nope. Not comingvfrom the water pump. That had been replaced already. The saga goes back a ways. The OEM water pump failed. Engine overheated. I suspect that a small crack developed then. Got the water pump replaced, all seemed well, until the car started using coolant again. I thought that maybe the head gasket failed (bolt stretch due to steam pockets?) since the number 2 and 3 spark plugs were wet. Still, coolant only went a little at a time. Then, one morning , the cranckcase was FULL of coolant. Had it towed to the dealer. Diagnosis - cracked block. Ordered a replacement from ZZPerformance.

Does not include throttle body, intake manifold, fuelrail, or injectors. It does include a new water pump and turbo assembly. Plus, it's a Gen 3 block, which supposedly addresses the issues causing the Gen 1 and Gen 2 blocks to crack. I'll keep the original motor and possibly replace the short block with a Gen 3 short block, also available from ZZPerformance at a ridiculously low price. That would turn my old Triumph TR6 into quite the sleeper!j

I have thought about putting an LNF into a Triumph just to F with those who think the Rover V8 is what every Brit car needed.

When you tear the old engine apart and find the crack post pictures please.

The venerable Rover V8 is a pretty neat power plant. It dates back to 1961 when GM debuted it in the Buick Skylark and Oldsmobile F-85 as the all aluminum 215. GM lost interest in the motor due to manufacturing costs (much larger cast iron V-8's were less expensive to manufacture) so they sold the rights to AMC, if memory serves me correctly, who used it in some of the Jeep lineup. British-Leyland acquired the rights from AMC. British-Leyland then found a home for it in just about everything British and it stayed in production until just a few years ago when BMW purchased Rover and started using BMW engines instead of the old aluminum V8. I had a Triumph TR8 with that motor. Loved it. Ran great, made pretty fair horsepower, and with tri-y headers and dual exhaust with free flowing mufflers made a sound that was awesome. However, it is now a dinosaur and I'd love to use an LNF to show those guys up.

I don't recall ever hearing the AMC part but yeah GM had problems with casting the block they sold it off and Rover stuck with it and made it work.  Funniest part was when Ford ended up owning Rover and got stuck having to make a GM designed engine.

Rogue : You might want to think twice before you hack that Triumph up according to Hemmings the V8 cars are becoming pretty desirable as only a limited number were imported into the US

Nope. Can't hack up the TR8. I already sold it. Besides, that was a really nifty car. Would have never hacked it. Far too rare. Sorry now that I sold it. I was thinking of replacing the inline 6 in my TR6 with the LNF. Hmmmm.....or maybe keep the inline 6 and fit the turbo to it......British inline 6's have a truly unique and beautiful sound about them. A turbocharged, fuel injected, inline 6......hmmmmmm......
