Engine Making Metal- The bad news

[merrja]

I got the pictures back from Triad today from my tear down and I must say that it's worse that I had hoped.  Pics attached.  The crack in the crankcase under #2 came as the biggest surprise....

[carusoam]

Now what's the plan?

ugh,

-a-

[gsxrpilot]

Do you know what caused this? 

[jetdriven]

Yes that's a typical lycoming four cylinder.

Those pictures remind me of my engine when I purchased my airplane.  Those lifters and galled cam comes from inactivity.  I've seen flight school's, who send their engines in for an overhaul because they reached TBO, (that get flown everyday) which looked brand new inside. 

Best thing for our engines is to fly them

I'm sorry I would be happy to buy you a couple of pitchers of beer.

Typical lycoming. Ya a lot of us have been there. Sorry for this. Anyone heard of the rotax doing this? I have yet to hear of it!

not any more. the local flying clubs arrow is having anoth engine put on after 400 hours SMOH two years ago. It flew often.  I'm not convinced that's working either.

Not sure what the point is, but I like it!

Typical Lycoming corrosion issues.  I'm guessing it not the first time your filter had metal in it.

Time in hours and Calander time? Where did the lifters come from?Factory cam?

Was the crank balanced?

looks a bit rough from most overhauls I have seen lately. 

just a few thoughts. 

 

All the best,

700 hours but the overhaul was done in 2005 and I put ~500 hours on in the last 4 years so the inactivity appears to be the culprit.    The case is out to see if it's repairable, but I may move up to the factory reman so I can get the roller tappets.  More news to follow.   Thanks for all the posts!

Fantastic!!

unfortunately you likely won't be able to get a factory engine.  To be accepted for a core it must be in running operable condition and be less than 35 years old.  

The core value is 14k

and it's going to be a very expensive overhaul because so much stuff was scored from metal in the oil.

Ewwwww!

[Htwjr]

When did Lycoming start using roller tappets on the factory remans?

[jetdriven]

2005 for most models.

Allow me:  A cold piece of idle steel being attacked by the elements with the statement- "Now this sucks".  Yes, indeed.  This does suck...

[merrja]

According to Airpower, if the engine was running when last in use, then you can get the factory rebuild and 0 time.  IS this wrong?

[jetdriven]

It cannot be disassembled. 

 

Here is their core policy.

[KSMooniac]

That does indeed suck.  Byron is correct about the core policy and disassembly.  Not sure if it is feasible to put it back together or not and give it a try if you're inclined to try to get by with that or not.

I believe the case crack at #2 is fairly common for our engines.  I'm not sure which engine you have, but I have a lot of good leftover internals from my salvage IO-360-A3B6D that I'll sell for reasonable money.  Accessory gears, oil pump, lifters/tappets, connecting rods off the top of my head.  No cam or crank, though.  It might be helpful if you end up having to rebuild what you have.

Engine is now in the test cell at Triad.. Complete overhaul, new crank case, rods, cam, cylinders, prop repack, prop governor.... an expensive day for sure!  If I had it to do over, I would have purchased the reman from Lycoming, but hindsight is always 20/20

Seriously how much is this engine going to cost, just the engine itself?

~$32K :(
