Hi, My 1776cc CT engine sounds like a bag of spanners. It has done 12000 miles since rebuild and has bits of metal in the oil.
Should i have it rebuilt again or buy a second hand cu 2litre off fleabay and run that until it dies and then have that rebuilt . i know it's going to cost either way but which is best long term
rebuild ct again or get a 2.0 L

It really depends on what is wrong with it. This is me sticking my neck out because I probably built it and I'd like to know what has gone wrong!
The CT was flawed on the top end, not the bottom end. The crank etc is the same as type 1 and strong enough to take 1776. The top end was terrible until you fitted type 1 barrels, pistons and heads which brought the compression down and made it last.
Upping the capacity to 1776 and reducing the compression should make the engine more reliable. I now semi hemi the heads to keep the compression nice and low.
During the last 4 weeks i have had a glut of type 4 engines, mainly CU with loose valve guides, seats adrift, knackered pistons due to debris damage and bore washed due to knackered old carbs. They ain't angels either. In fact, I'm working on making it possible to fit the heat exchangers from the CU onto the early, oval port heads, meaning that the stacks of second hand 1700 heads will be useable with some machining.
If the ancillaries on the CT are still good, and it is one I built, let me have a look at it.
The cooling fan is the same as type 4, and if I built it, it will have an extra cooler and remote filter.
Chuck it if you like, but if not, let me see what is wrong.

You'll all be pleased to know that I visited Groovie's van today and found that after 12,000 miles, the fan boss had come loose. The engine is lovely.
Next week, I'll visit groovy again, with another fan boss, an impact gun and a boss bolt and the van will be back on the road again.
Failing that, he could go and buy a nice second hand CU engine, with less power and no history
