Notorious for the cams seizing in the head. (Sorry done so many partly blocked oil way)

1980 Dolomite Sprint with a touch of BLTS Balanced Lightened and Tweaked 13B Rotary and SsuperCharged.
Back in my possession 22 September 2019. Rebuilding the Sprint time taken so far, 111Hrs@15/12/2020
212Hrs @31/12/2021 352 @ 28/11/2022 455Hrs @ 20/10/2023 565Hrs @ 07/12/2024
This is time taken at the Sprint not necessary time worked.

Project 13B Sprint now back on..
No Pistons No Cams how’s it gonna Run Brap Brap?
If you change the engine oil regularly, there's not anything wrong with the engine
for an SD1 the only rust is a little bit on both rear arches, the car needs new tyres as there old, hand brake needs looking at and oil leek on gearbox, and replaced the viscous unit

Quite possibly
But on newest cars at the time that haven’t had the blocks properly cleaned after machining swarf was still present.
Blocking oilways.
Then Rover changed there cleaning process.

Yes it was a Triumph engine, only ever used in the Rover SD1,a bit like the Stag V8 in the day no one liked them, but now every one wants them, today you can tune them so there almost as powerful as the V8

Wasn't that engine derived from the Triumph straight six?
Derived from certainly but much improved. The bottom end was substantially beefed up to address the known weaknesses of the OHV engine. Cylinder head very much follows the Sprint layout in concept but with only two valves per cylinder. Allegedly the 2.6 was under carburettored so as not to embarass the 3.5 V8

I've read the same about the 2.6, I think it also deliberately had very restrictive exhaust manifolds. It's supposed to respond very well to a few tuning modifications.
