I know a guy with a 998cc engine, but depending whether or not he'll throw in the manifolds/ ancillaries is kinda a dealbreaker, as the 875cc stuff won't fit on it and sourcing those is turning out to be a nightmare. Is there some motorbike engine that you can bolt in there? Or maybe one of these little turbo engines like the VW TSI or Ford EcoBoost? A 150bhp Imp would be terrifying. But in a good way.

GoodbyeTurtles posted:... I need to do a compression test. If possible do a cylinder leakage test too. Often an engine will show good compression but will have excessing cylinder leakage where the rings or cylinders are worn, can cause excessive blowby and oil consumption.

GoodbyeTurtles posted:I've been meaning to nag the boss into getting one of those for a while now, really good bits of kit if you know what you're doing with them. Though I still have access to the kit they have at college so I may be able to test it there for learning reasons. Worth having. They show a lot more than compression tests do. I have a valve in my toolbox from a 3-cylinder Polo that had rough running. Everything checked fine, compression was ok, valve has holes burned through it. cylinder leakage showed what nothing else could.

Cakefool posted:How did it have any compression at all with a holed valve? No idea. And not just one hole and not just one valve!

GoodbyeTurtles posted:Managed to do the compression test and leakage test. Rings/bores i would guess. Did you check leakage with the piston and the top and bottom of the cylinder? Usually you find there's more wear at the top of the bore and that shows on the leakage test. If you're down on compression but leakage is identical top to bottom it may be just the rings.

GoodbyeTurtles posted:I couldn't stop it turning over when plugging the air-line in, even in gear with the handbrake on. I'd have to lock the crankshaft somehow and there isn't any access to the flywheel to lock it there. You'll just need to have it mic'd and see if you've got worn or ovalled bores. Often you can get away with just a hone and a set of rings, which isn't a huge deal. Also, your handbrake must be even more useless than mine if it can't even stop the engine turning over, under air pressure.

GoodbyeTurtles posted:Maybe a higher gear would have been better... Have the block deck checked with a straight edge for warpage before skimming it, as they tend not to warp quite as much as heads. And once torqued up they often pull straight with no issues. I have a great engine shop near me (North London) where if i call in advance they skim heads for me while i wait. Place looks like a bunch of big sheds, but they're awesome.
