Unfortunately I do not tend to drive the FRP as often as I should (its one of several cars I own) but after a recent incident with low oil and high rev's I heared the dreaded "big end bearing" noise clonking, I knew exactly what I had to do, I had to get my hands dirty and do what I'd been promising myself I would finally get around to, i.e. put in the spare 'new' bare zetec engine I had sitting in the corner of my garage. Thankfully I am mechanically competant and I do have full workshop facilities and tools at my disposal. This job isn't as daunting as it sounds, just very time consuming. After all the new bare engine contains a fully balanced new crank, pistons, conrods, valves and head all ready to go. All I needed to do was strip down my old FRP engine bare and swap over the racing cams.
While it was a major low in my FRP ownership hearing that dreaded clonk, clonking when I rev'd the engine, I felt happy in the knowledge that I had everything I needed to get started. So, last week I decided that while we are having all of this cold weather I would dedicate a week of my time (and family members bringing me copious amounts of tea, coffee and biscuits) to swap over to my spare (unused) new Zetec 1.7 SE engine I'd sourced from ebay for £500 (a bargin!) a while ago now.
After inspecting the original FRP cams I cleaned them up and re-used them in the new 1.7 Zetec SE engine. After some diagnostics work I learned it was Cylinder 4's bearing that went west.... oh dear. What a shame.
Anyway, its all in good shape now. Kind of amazing really that I've managed to fit essentially a full new engine, new clutch and all new fluids along with a full refresh of the brakes all for less than a set of tyres for the Ferrari

This has been quite an extensive refresh actually and thankfully the car is driving absolutely brilliantly again. Like driving a new FRP Brakes are now smooth and progressive (had an issue with sticky calipers before), clutch is light and engaging perfectly with good pickup, new engine is super smooth and torquey, its rev's cleanly and power is now restored, just without any of those dreaded clonks (engine never felt this good before since I owned the car).
Just have to wait for all of this snow to clear now and drive it a few thousand miles for the new engine to bed in...
During winter I think I may opt to do a full bare metal 'concours' respray to 'as new' standard. In the meantime I plan to replace as many suspension parts as possible with new. Got my eye on one of those spare cheap FRP gearboxes, would make a nice complement to the new engine just wish I would have seen it BEFORE I put the car back together
Another FRP back in fine fettle!
