John,I don't. I've never disturbed the rockers [by this I mean taken them off their shaft] for any reason, so what you've said will be checked. I'm just going to put it back together loosely for the moment and forget about flying until I can get the finances to rebuild, at the moment it looks as if I'm up for about another $4k to get back into the air, so it's going to be a while, if at all.Cheers,Nick.Nicholas TomlinAlarmist - www.alarmist.com.au - we scare for you

Come On Nick.As you are one of the most pro-active members on this forum, the last thing I wanna hear from you is stuff like..."forget about flyin" and "if at all". Damn! That's not the dude I got to know on this forum.Mate look how long some of these rebuilds take. People have busy lives and sometimes we find ourselves behind the eight ball because we have to prioritise BUT "if at all", Nah, not hearin it Nick. There's always a buddy who will take you for a lap, be it rotor or fixed wing. Keep the dream alive Nick and keep us posted.Best regardsMitch.

Nick, Before you go thinking everybody hates you and you go and eat worms, At worst, to repair your motor You MAY have damaged a head (but unlikely) in which case I have many that you would be welcome to. I cetainly have a few pushrods that I would even post to you for FREE!I wouldnt think that the pushrod broke when the prop hit the ground, these motors are fairly tough (having had two props destroyed myself) some times things just break.Im sure that a new prop, rotors and probably a good look at your mast and you will be flying again in no time.....The wife will get used to the idea!mark.

G'day Nick,Number one rule with EA81 is to take out the push rods and roll them on glass or milled surface and check for bending. If they break, the cam follower comes out of the guide and instant "no oil pressure". The push rods fatigue if bent. All a bit late, I know, but not for next time.Fred

Gid'ay Nick. I have seen bent pushrods before but never a broken one. It is most likely caused by some other problem in the engine. If a reduction driven Subaru looses one cylinder it can normally maintain height one three cylinders. If yours couldn't then this also suggests some other problem. Your engine still should have four good compressions, even with a broken pushrod. If not then there is a problem with a valve or piston that could have resulted in pushrod breakage. It is not unusual for early model EA81's to have exhaust valve failure, which results in damaged head, piston and pushrod, and in rarer cases, the bore as well.Never straighten and re-use a bent pushrod. It is also important as John said to make sure that the valve rocker assemblies are assembled and installed correctly. They are marked "L" and "R" for ease of assembly (as long as they have not been butchered)Beginner's quotation - "I hit a bad gust of wind just as I took off"Tim McClureBroken Hill

Nick, Don't eat worms , they taste like dirt... I have an EA 81 manual you can borrow , give us a ring if you are passing thru Singleton & you can grab it. There is a Subie wrecker in Newcaslte ,Cardiff Auto Dismantlers on Munibung Rd. , that had a couple of EA 81's when I was ther last - may be worth a phone call. You'll be right , Nick. Giving up gyro flying is like giving up sex ( except I can fly for an hour or more easy....)
