Turbocharged Manifold Pressure

Thanks for the reply.

I wouldn't have thought about the filter. I'll add that to the list.

The rear engine has oil leaks like many seem to. I think it's the pushrod tube seals that are leaking, but I'll look more closely around the turbo.

Experienced input is always appreciated!

I am having the same issue but on my front engine. I do know when I bought the plane 2 months ago, that one of the cylinders has a low compression (55psi). I havent been able to go down the list you posted...so that give me some additional areas to check for myself.

I'll post my findings here. To anyone reading, please do the same.

The plane does have a data-recording engine monitoring system. I may spend the $100 and send the files from the last few flights to Savvy Aviation for their experts to analyze.

Anybody here ever use their service before?

Your lists looks appropriate. I would use Savvy based upon what I have seen and been told about the companies reputation. I personally have no first hand experience. Best to analyze before "attacking with tools"

The fellow with a 55 PSI cylinder. I wouldn't condemn that cylinder right away without doing a borescope. Followed up by lapping the valves if the borescope inspections leads you to believe a valve problem exists. Burnt valves also can be corrected without removing the cylinder in various cases. Again look at the information from EAA/Savvy on YouTube and go from there.

I'm a SAAVY Guy; Pro and Breakdown. I haven't had any problems, just receive the interval engine reports. I'm going to turn the maintenance over to them as soon as I get the aftermath of my latest annual over and that portion of the records digitized.

I also use Blackstone for the oil analysis.

TCM issued Service Bulletin M84-15 to provide official guidance to mechanics about performing compression tests on TCM engines.

Very informative way to analyze cylinder health. Eliminates a lot of old wifes tales. Regards, Joe

I hope it is not the turbocharger. My planes has been down 10 months waiting for one and I paid dearly for it. Good luck!
