Mineral oil accelerates wear, with abrasives (blow by combustion products) I speak from recent experience, along with Ed Collins inventor of cam guard and has intrests in asl remaufacturing parts such as camshafts. He said it’s common to see a spallled camshaft a few hindered hours after a...

Since this is a cylinder replacement and the original camshaft and lifters are being retained I would NOT run mineral oil. Phillips 20-50 x/c, instead. Mineral oil combined with high blow by of the new cylinder is very abrasive on the camshaft and lifters. We know these parts are marginal...

Your plane must be flown a lot. The major concern is inactive time, with oil not staying on cam/lifters as long, but I’d also ask did you see how much lead was collected inside your engine? Sent from my iPhone using Tapatalk Pro

The 15w-50 semi synthetic oil has no business being in a leaded fueled airplane. The synthetic component just doesn’t do a good job suspending the lead bromine sludge. Also interesting that many top mechanics such as mike Busch seem to see high degree of cam/lifter pitting with this oil. I...

Ya straight weight is outdated, old technology. The multiweight protects better even at higher oil temps. It also flows quicker at cold start. The only reason to use a straight 50w is storage. That is the ONLY REASON. Sent from my iPhone using Tapatalk Pro

Unless you live in a place that is always warmer than 60-70f, a multi weight oil is ALWAYS going to be better. The oil pumps faster to critical parts on start up. Most wear happens at start up. Unless your running 300f oil temps the straight 50w does no better that the multi weight oil...

Just bought a 2015 vw passat tdi (diesel) 6 speed manual and chipped it to 190hp/350ft lbs of tq. Funnest car I’ve ever driven. Steering and brakes feel like it’s on rails and glued to the road. It’s no vett, but the diesel torque is awesome. Power band almost close to flat from...

I took off in my J at 63f with 1/2 tank and 2 people. What a dog. Tip toe off the runway. The turbo would have been nice. Sent from my iPhone using Tapatalk Pro

I did not know that. Looking back I was preheated in my 182 days. Speaking of starting when cold, with reduced battery capacities, to bad when plugging in the engine it doesn’t also have a warm heated pad against the battery also powering a battery maintainer. Kinda tough to start when the...

Turning the prop by hand is dumb. Whoever wrote that manual your reading about for the IO-470 didn’t know what he was talking about. All you are doing is scrapping off the oil off the cylinder walls. If your starting it immediately after pulling it though I doubt it will hurt anything but...

At home airport RST tower said If you can keep your speed up and you will be #1. Got jet traffic at 5 miles. Crossed mid-field in the Mooney at 210kts. That might be a bit excessive though lol...... Sent from my iPhone using Tapatalk Pro

Not many, by I’ve got to look inside lots! It seems the ones that get run often and for extended periods, with scheduled crankcase oil changes seem to look good. I think the ones that look worn out sit longer then, the subsequent wear comes from abrasives such as rough interface between...

No problem. A gas pickup with 200,000 miles has 5k-6k hours on it. Sure the steady state cruise loads are higher on aircraft but they don’t get spun upto 5,000rpms or more, and spend most of there hours in steady state cruise. Even gas generators in boats or industry that get run at high % of...

The term “trues out” is used to describe the max cruise speed of the aircraft when the owner of said aircraft is lying to his friends about how fast his spam can really goes. Sent from my iPhone using Tapatalk Pro

Got about 1500 hours in a Mooney 201, and the biggest reason to use take off flap setting In my opinion is, it’s good to form good habits. Specifically if the fan in front quits spinning just after lift off and landing on the same 10,000 ft runway isn’t a option cause it’s behind you or will be...

Ya definitely not lean as you were rich of peak and peak at that power setting is somewhere in the 9gph range. Air bubble? Sent from my iPhone using Tapatalk

He might be running a early J with 25btdc timing and in that case he is better off with as much rpm as he can get, given timing is fixed. RPMS increase detonation margin, reduce throttle or LOP IF NECESSARY. Sent from my iPhone using Tapatalk

He got something very wrong. I have 1,000 hours in a J and don't see those temps. Normally #1 and #4 cylinders need metal modification but I think he has some serious rubber baffle issues. On #1 trim down the front deflector baffle 3/4" and #4 bend up the metal baffle to rob some air from...

Why not hit the starter and then pump throttle after the blade starts to turn. You start cranking lean and then fuel hits and it fires. Never again do you have to guess if your lean or flooded. Just don't pump without cranking. Sent from my iPhone using Tapatalk

Hank I agree! Put 100 hours on in a arrow then bought the mooney J. Same gas per hour 132kts vs 160kts! Oh and the mooney can, if you want carry 1/3 more fuel! MN to Florida non stop. Oh and if going east to NY and big tail winds exist in the FLs yep run it up to FL210, and still true...
