Engine question

I personally contend that if an engine ever spins bearings, or flattens cam
shaft and lifters, or disintegrates a plastic timing gear, that YOU SHOULD
NEVER, EVER, CONSIDER using the existing cooler or lines again.
You can do what you want to your own engine, and maybe, just maybe,
you could get lucky and not have to pay the price out of pocket, but the
odds are severely stacked against you. You start adding up tow costs,
inconvenience of being stranded, shoddy repairs by people that do not know
your coaches, and you get the picture. Just my opinion, yours might vary.

John,
The one in the Aluminum rad is lot different.
One needs to cut the tank and Tig it. My Filter Welder can do it , but too
much labor to mess with.
We no longer handle the Griffen as he is not competitive, so we handle
anther one that fits like the exact one and cools like the Griffen.

These discussions about recently rebuilt engines blowing up, always makes me sick to my stomach. I am running a rebuilt S&J that I need to check
my odometer to see when I need to get the next oil change done... So far so good, but one never really knows. It is not only the $$ lost, the time,
and mostly the confidence is what one may never gain back.

There is not any really good info as to replacing, or really knowing one way or another the bypass is working or not, from what I remember last
summer. I do know that new oil lines and my new radiator were costly, but I am hoping are insurance to keep my engine going. It is not so much the
$$$'s involved, it is the loss of confidence in driving.

as for cleaning the lines out, I did notice that not all coolers are the same. I bought a superior radiator, and that oil cooler is nothing more
then a snake tube. Probably pretty easily cleaned, as opposed to other coolers. I hope I never have to worry about cleaning it.

Aircraft engines remanufactured by the factory don’t exhibit the “infant mortality” that rebuilt automotive engines do.

There are rebuilders who have the same problems as automotive rebuilders. The FAA used to publish field failure numbers, but I could not find them readily.

Considering that a zero timed six cylinder aircraft engine rebuild is about 6 times the cost of an S&J 455, that may have something to do with it.

Also, I believe the FAA mandates new (not cleaned) coolers. It could have been the persnickety (pedantic) A&P I used.

Lastly, we are at a point where nearly all the castings have been through one rebuild. How many times can you dress a crank before it’s going to precipitate a failure?

I had a camshaft that met all the specs, but resulted in poor oil pressure. Lots of variables and stacking tolerances that cause problems. Also, no one seems to know them like the factory.

So it is.... and beyond replace almost everything, will continue to be.

Oil cooler is not a simple tube, but one that has turbulators built into
them so the oil can conduct to the wall. Externally they look smooth.

I dont think it would scare
Anybody. I just dont know how you can compare. I have seen some really good engines installed by some bad installers, just the same as I have
seen bad engines done by rebuilders.

I talked to dozens of people last summer about engine and their experiences and problems. I did not write it all down, but there was very little
consistencies. The only thing that was consistent was poor installation, and poor timing.

The majority of problems were engines installed by unknown shops away from home. Some from known "reputable builders". And some from unknown.

Other then that group, there was no consistency on who built an engine on if it lasted or failed.

At MAC's, all engines with fitted oil coolers had new coolers from Lycoming or Teledyne/Continental as appropriate. After consulting the gurus, I
agree with Hupy. My new one will run without the cooler unless there's a temp problem... which I doubt. Radiator shop was asked about cleaning the
cooler, "We might be able to". Pass.

Some shops think they can blow out the cooler with brake fluid and it is good to go?!

Yes, some luck out, but I won't do that for my customers or for myself.
