 |
|
<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> 914 Owners,
While beating my head against the wall on my leaky turbo I reviewed all that I did.
One...My engine was a used 914 and the turbo was drippy.
Two...I gave the turbo to a friend who works for a reputable turbo rebuild facility but not the Garrett factory.
Three...A new standard Garrett rebuild kit was installed and the turbo refurbished and returned.
Result:
Initial start up and boost are normal, but I have this pesky leak after about two or three days.
The ball check valve is not leaking when removed and tested.
The turbo seal is leaking. Why?
The Rotax turbo is a few thousands different in diameter than a standard Garrett as it is a Rotax Proprietary Part requiring a turbo replacement and not just a rebuild kit. If I continue to run with what I have, I'm sure it will eventually fail.
Solution:
Well it is off to Garrett or Jason Parker of Extreme Aircraft Engines to get the seals redone properly, but at a higher price now. Jason has a line on the Exact Rotax turbo core replacement at about $750. Jason is at http://www.extremeaircraftengines.com
Bottom Line:
Don't just send your turbo to anybody.
Bud Yerly
On a side note,
Jason Parker has sold 8 engines just in the last half of this year and is under contract by Sea Ray for a full firewall forward. For the Europa he has a full kit which only nicks the passenger foot well but otherwise fits very well. Wire and fuel now are pre set up and the engine is as plug and play as you can get. Prices with intercooler are just below 914 prices and are zero time. I don't make a cent off of them so this is an unsolicited endorsement.

Hi Bud
Thanks for the update on the turbo. When mine craps out, at least I"ll know where to send for overhaul...
On a different note.... Thanks for the "paper" on the cooling of the 914 in monowheels...There is a lot of experience in that paper. Most of us here in Florida have cooling problems and some have been solved, but most still linger despite our efforts to cure the "uncurable". In the air I run usually 190 degrees both on oil and coolant.. On the ground, coolant will reach redline by time I,m released for takeoff by the tower.
