Roger Keys Posted March 30, 2021 Share Posted March 30, 2021 Ok, I'll be first 😋. I have just started on my sprint's resurrection. For those not familiar with it, bought it in 1990, modified it and rebuilt it several times. Final spec was fully built engine, ported head, twin 45's STR91 can etc. 195 bhp. Which was nice. It did, I think, five RBRR's. In 2002 I'd got a bit bored with it and sold it. Bizzarely to a guy I knew from back in the early 90's. I never saw it again until 2013 when Dave Kent sent me a link to eBay with it for sale. Back with the same chap, but sold in the interim, it was now broken, and a bit more rusty. Ran on three cylinders. So I bought it back😊😊. It's been stored ever since. But I'm back on it now. Here is a pic ( I hope) of the engine and box coming out.  Quote Link to comment Share on other sites More sharing options...
Ben Hutchings Posted March 31, 2021 Share Posted March 31, 2021 Well that's pretty exciting, old friends, reunited (although we don't usually take our friends apart and rebuild them). Looking forward to seeing progress. Quote Link to comment Share on other sites More sharing options...

Lucky man. You don't want to know the rent, trust me. I can only do it as the company effectively pays for it. Need to crack on while I have it!

Roger Keys Posted May 20, 2021 Author Share Posted May 20, 2021 Not much progress to report. Continuing work on the house after a flood, and a paying mustang job, getting in the way. However, with the engine out, ive popped off the cylinder head to investigate the "running on 3 cylinders" issue. Wasnt really conclusive so far. Its certainly not a "mechanical" fault with the engine. I was expecting a valve issue on no1, but they are fine. What i did find was a double score mark up the side of no1 bore. Its not deep, and ceretainly isnt the source of the misfire, but it is very odd. The oil control rings have worn to the grooves. So, im going to need at least one cylinders worth of of std size oil control rings. The odd thing is, the head is immaculate internally. Its done next to no mileage since being fitted. I did this back in early 90's. However, this wear on the rings logically must have happened over a longer time. I either need another std size block, or i just leave it. It was discussed with others a while back, but since then, ive concluded (my memory is hopeless) that the modified head was put on the existing engine in the car. Doing so would mean the piston would be at TDC during the swap. So if it was scored back then already, id never have known. Which explains the wear on the oil control rings, but a virtually as new top end! So as a minimum i need some oil control rings. Dont want aftermarket, just some good originals. The cylinder head shows a significant difference in mixture between the front 2 and rear 2 cylinders. That makes no sense either as its on webers, set up the same, or should be. I note that the vac take off is on no2 runner rather than shared across all 4 like a standard intake? Might this be an issue? Took the axle off too. That needs some new oil seals. And painting. Thats it for now   Quote Link to comment Share on other sites More sharing options...

Roger Keys Posted September 11, 2021 Author Share Posted September 11, 2021 Not much progress to report. Too much other stuff/work/life at the moment. But, bought an aqua blaster. Super useful. Amongst other things, put the cylinder head and intake manifold through it. And tackled the corrosion on the bottom of the wing/sill. The wing itself was pretty good, but the sill behind it was holed. Fortunately didnt extend far at all. So patched and wing refitted. 2 Quote Link to comment Share on other sites More sharing options...

Roger Keys Posted September 17, 2021 Author Share Posted September 17, 2021 In between coats of paint drying on a non triumph job, i thought id prep some more dolomite parts. What i found is that the aqua blaster is great for cleaning up old rubber parts. The subframe mounts have come up like new. Still soft and flexible. I guess the exposed parts being covered in underseal from new helped prolong their life. Then i did one of the headlamp rings too. Cany de-rust this with acid as it has the brass inserts for the adjusters. Â 1 Quote Link to comment Share on other sites More sharing options...
Roger Keys Posted September 22, 2021 Author Share Posted September 22, 2021 Tonight we used the portable home made spray booth 🙂 Mostly an assortment of dolomite parts. Apart from the diffs. Definitely not triumph. Needs an extra light behind me as its too dark.   Quote Link to comment Share on other sites More sharing options...
Martins Stag Posted September 27, 2021 Share Posted September 27, 2021 Roger Just wondered is the Sprint Sump the same bolt hole pattern as a Stag? I am sure it won't fit but I just wondered about the bolt holes.....  Martin Quote Link to comment Share on other sites More sharing options...

Roger Keys Posted October 6, 2021 Author Share Posted October 6, 2021 (edited) Meanwhile, back to work.. All refurbished original parts. In the right finishes . I think/hope? For a light restration, i may be getting carried away? Edited October 7, 2021 by roger keys Quote Link to comment Share on other sites More sharing options...
Roger Keys Posted December 11, 2021 Author Share Posted December 11, 2021 Not a great deal of action lately but some at least. Decided to replace the block on the engine to get over the bore scoring, as i dont want to go oversize pistons, rebalance etc, etc. So got an orginal size unlinered 1850 block. This is at the machine shop now. Its been acid dipped and then bored out. Should have it back next week. While that was away, ive stripped pretty much everythinmg else off the engine. All the bolts, brackets etc have gone to the platers from zinc plating. Cleaned up this pistons in the aqua blaster. Came up like brand new. And also managed to get a set of NOS piston rings too. Which im most pleased about. Â Â 2 Quote Link to comment Share on other sites More sharing options...
Roger Keys Posted December 11, 2021 Author Share Posted December 11, 2021 While i wait for all my engine bits to come back, i thought id have a stab at the carbs. They work fine, but look pretty sorry for themselves. Only one solution. Aqua blasting. However, that does mean a total strip down. Because i have no idea what im doing, im doing one at a time. Sort of. All the exterior plated parts have been removed from both and again, off to the platers. The first carb was then completely stripped. Before and after pics, Next job is to reassemble. 1 Quote Link to comment Share on other sites More sharing options...
