There was an article in Kitplanes magazine several months ago about a guy
who built an elaborate blower system to give his new (certified) engine the
same ventilation it would get in flight. That way he could do the complete
break in with the engine in a fixed location.

Open till about the 80s we used to have to break in automobile engines to. You
did go down the road and would never hold the same speed for very long.

Bob,
Steve Bennett broke in my 2180 VW before he shipped it to me. He told me he
ran it for one and a half hours at wide open throttle. He was careful not to
let the engine overheat during that break in. If the engine started to
overheat he would shut down, let it cool off and then run some m
Hi Bob,
Sorry to hear you didn't do your own work . . . now you don't know for
sure if the shop re-used old springs, or how concentrically they seated
the valves, etc. Did they cut new seats? Did they use swivel-feet on
the rockers to protect your guides? What did the combustion chambers

Just thought I'd mention that since you're going through all the trouble
of taking your top end apart, it wouldn't hurt to put new valves
(Manleys) and springs (stock VW). You'll want to bead or soda blast your
heads to clean them up and if you really want to finesse it, index the
plugs. If you'r
I agree with Donald, buy the spring loaded pushrod tubes that can be installed
after you put the heads on. If you use the stock pushrod tubes it is to easy to
have a head on a little crooked and damage the head, trust me I did it and had
to buy a new head. I used the spring loaded pushrod tubes
Bob. Piece of cake to do with engine block still mounted to firewall. push
rod covers are a bit tricky but I bought the 2 piece rod covers that have
compression spring and it went fine. Even stock rod covers are not to bad.
You just need to go slow and watch your seal's as your head goes back on.

Hi Bob
I have changed cylinders multiple times without removing shortblock from
the mount.
If you just lap the valves you can probably reuse the existing pushrods,
if the valve adjusters need to be backed off too far you can add shims
under the rocker shaft pedestals.
Reassembly of the cyl
Hi All
I have dismantled the top end of my Great Plains 2180 which is still on the
airplane and it occurred to me that replacing the pushrod etc. may present some
challenges.
Has anyone done this or should I actually remove the block from the airplane?
Basically just want to hone the cylinders,i
