Not at all, diesel is a light weight oil in essence, the engine just had a nice top oil run through it, no harm done at all.

Re: 0470 updraft continental

You need a reverse rotation box for the tach to operate. Oil temp at 220 is a bit high but not danger zone, what cooler are you running?

Re: Engine turning while towing

Not uncommon to windmill, no harm in it, proper rotation, pre oiling for cold starting. My cousin would sneak over to a buddy's 65 Continental and kick the mags on when he wasn't looking, boat would be idling when he got to the ramp, funny wtf moment.

Re: 220 gpu engines

Drill rear oil ports to 11/16 and tap 3/8 npt, same on cooler if you got one with them.
Replace exhaust with headers.
Numerous upgrades can be made to them.

Any shrouding or ductwork goes, the studs on rear of case can be removed, the butterfly valve and servo off left rear side, plug oil supply port with a setscrew, build block off plate.

Re: GPU accessory case on E185?

Yes, I have done it, basic modification to start with bit tricky part was machining oil pressure relief valve into cover, the rest is like doing a dual mag conversion on a gpu, you will need to machine a crank gear spacer out of .125 aluminum and use a 220 crank and cam gear plus mag drive gears and...

Re: pe-90 questions

Grease gun adapted to spark plug thread, pump them off. But I would first fill crankcase with phosphoric acid to eat a lot of the rust away, cylinders likely junk anyway.

Re: Pickled engines?

How was it pickled?
Fill it with fresh oil, pull top plugs, spin it over with starter till oil pressure builds, reinstall plugs and if fuel is primed up, crank it up, run it to about 1800 rpm untill hot. Let it cool and check things over.

An o470-13 would be closest to mounting as the 220 but prop adapter and such are different and are longer.

Looks like a warp drive, no big deal, can run without it unless major vibration is present.
Gus Guell is the man,,, he apprenticed under my father at air carrier engine service and then aerothrust, lots of memories.

Re: Igso 540 question

There is a spool kit for them but you will need to go electronic ignition, I'd suggest leave the gear on it, as it helps get the rpm higher to produce correct boost pressures otherwise it will be a slug.

The stock 220 camshaft if part number ends in 878 is same as e185-225, they perform very well with a smooth idle.

Re: 220 bogs and loses power at wide open throttle.

Pull fuel inlet adapter off the bowl, remove sintered bronze filter and spring and throw them away. If none present then be sure of tank vent clear of debris, also depending on electric pump type, it may or may not allow full free flow when off, and it may have a screen that is clogged.

Re: 0470 blow-by / leak down

Leakdown and compression tests give you a note on which cylinder is out of balance with the others that are stable, by reading your diagnostic numbers it isn't too far off to be worried about it, oil consumption or high oil temperature would be of concern to make an overhaul decision, connies huff a...
