Electromagnetic piston movement with no need for cranks or rods or pins.... + electromagnetic camless valve actuation....the stuff of dreams :) Well Lotus etc have the valve thing but not the crankless engine ;)

 

Crankless engine? Wouldn't that be like having a wheeless car? :tongue:

but not the crankless engine
Not sure a crankless engine would be much use.

 

I would have the engine out. It's got to be easier to check and rebuild in a workshop (assuming you have one) or garage than with the engine still in situ. I must admit, I'm surprised it's not holed pistons.

 

Best of luck and I hope it turns out simpler than it appears Jake.

I was thinking about that Gordon. If an endoscope can confirm that there is piston/bore damage (and there very likely is) the engine will have to come out so there's no point me struggling to get the head off in situ.

 

How do I find someone with an endoscope who can come to me? I could look up "Endoscopy" in the yellow pages but I don't think I'll have much luck there.

 

Jake ,have only just seen this thread.I have somewhere an endoscope burried in my loft from back in the day of detonating 350 lc engines at an alarming rate.

If you havent already decided on the head strip i can try and locate it some time this week.(have not used it for 10 years)

let me know i would gladly lend you if it would help.

Mig and I once had a half drunken conversation about using the head as an electromagnet and using it to create a force on the pistons.... we were chatting about it for quite a while I seem to remember, but unfortunately was lashed so can't remember much of what we were saying.

 

As for aluminium, Everything is magnetic to some degree - even people! ;)

 

 

Blimey ..I do sorta remember that one .....we was a bit lashed at the time ...but hey good ideas happen in a bar all the time ...SHHHHHH you have just given our top secret idea away :p wonder if it could be done :rtfm:

VAG group were looking into this in a big way to eliminate cams all together ....I once delivered a prototype engine to the VAG stand at a show at NEC I attended in 1999 and was talking to head tech ...the problem they were trying to overcome was finding solenoids that could react quick enough ...dont know what happened to it or if it got shelved or not ...but think of the possibilities.....very ajustable cam timing

:thumbs:

Yeah same with lotus too it, it ran but couldn't be packaged small enough to be practical...but yeah, camless, digitally controlled/adjusted lift and duration, any position at anytime would be fantastic.

Thanks mate but I managed to borrow an endoscope locally.

 

350LC eh? Fine machines, I've owned a couple of those.
