I'll discuss the inspection with my mechanic but I know he has never done it. I need to be sure he's confident of doing the work or I'll let Lasar do the job. Looks like we have another 30 hours before the AD is due but I thought we'd do it at this annual. Having second thoughts about it now. I may wait the six or so months and address the AD then. Thanks for all your input everyone.

Spoke with the guys at lasar. 200 for inspection(not bad) , 2400 for rebuild (a little worse) . But I really like when my gear goes up and down when I want it to. Thx for the recommend.

Remember approximate cost on lasers end?

About time for AD75-23-04 on my m20 F. Looks to be model #M20-190A. Any recommendations as to where would be the best place to send the unit? I'm in North Carolina. It looks like the work could be done by a knowledgeable msc. My mechanic will remove and replace but not familiar enough to do the inspection . Any suggestions would be appreciated.

Going to order a EDM730 this week. Until the end of April they're offering rebates of $300 on the 730, the same on the 900 series. Varies by model.

This is probably not going to help you but I'll be interested to find out the cause. I just overheated my number 4 cylinder and had to replace the rings and piston. I only have a single probe cht so wasn't aware of it till I started having a problem. My understanding is that #4 is usually one of the "cooler" running cylinders. Maybe not. We could not find a cause for my problem and with only a little over 100smoh a little troubling. I'm purchasing an engine analyzer and hopefully won't have an issue arise unexpectedly. I do have an F model so it may not be that relevant .

what runway? I'm catching that Bird!

I think I had a dream about one last night.

That new EI unit looks similar to the JP unit Jose. I could see how the graph display would be easier to read.

I'll check out some of the products you guys have mentioned. Don't think I can get too carried away as I have limited real estate in the old panel. The 930 looks awesome Bob. And I see that view of Long island every month or two as I have family out towards Islip. Time to hit the sack and have dreams of huge color displays with more information than my mind can process. I think I may be one of those people who do dream in color. Thanks for all the advice.

Heh, now that I think about my plane is mid 60's technology. Mid 90's doesn't sound that bad.

So I guess the big question is "how much for the up to date version" of an engine analyzer? Are we talking about an 830 model or something different.?

Now that you talked me out of it you'll have to sell it to someone else but thanks for the input . It's about 400 cheaper for the EI unit but I guess theres good reason.

Just put Goodyear flight specials on my F model. 119 for mains and 99 for nosewheel. Old tires were Airhawks and though they still had tread left were showing cracks from old age. Retreads are supposed to be a good deal but I wanted new tires and they were about half the price of the Goodyear 3's but still a new Goodyear tire. Only had them for a week so hard to tell you how they'll last. I hope pretty well.

Has anyone used the Electronic Intn'l US-8A engine analyzer? Either that or the EDM700 by JP? I assume the JP unit is good as many people seem to use them. I do have the EI unit for fuel flow installed already and it seems fine. Any thoughts?

Hadn't thought of it. Last time we just measured the fuel flow in calibrated jars and compared the levels.

I pulled all the injectors before we pulled the cylinder but didn't really look that closely. I remember when we did the first annual one injector was not putting out as much fuel as the others. We replaced that injector at that time. It was actually the wrong injector for the plane. I can't remember if it was that cylinder or not but it was over a year ago. Who knows maybe the damage occurred back then.

Unsure as to the cause. Fuel issue at that cylinder is a good a guess as any because all the others were good. All I have is the single probe on the cylinder head(it was not on that cylinder ) and the standard egt gauge. May is the annual and I have already discussed it with my mechanic. I should have listened to him when he suggested I install one when I bought the plane. Is JPI what everybodys using?

I meant to take a picture before I left the shop today but I didn't. I can't go by again till Thursday but I'll take a picture when I go. The cylinder looked fine but the piston was another story. It looked "dark varnished brown" on the bottom and just that "varnished color on the outside. I don't know why that was the cylinder to get hot but all the others appeared normal. Didn't check fuel flow since last annual. Sounds like a good idea to check when the engine gets put back together.

Well I brought the plane to my mechanic this morning. Engine running rough and blowing smoke and some oil out of the breather tube. Compressions all checked good and no oil on any plugs. Looked in the cylinders with the camera and could not determine which cylinder was the problem but it seemed apparent we had a ring or cylinder issue. By the time I took everything apart we agreed it was prudent to pull all the cylinders to see what was going on. Got to the number 4 cylinder and the rings were "frozen" in the piston. I had apparently "cooked" the piston. I don't know for sure how I overheated that cylinder but it was clear it was the problem. May get an engine monitor of some type at the annual coming up in may. Being my mechanic lets me do most of the grunt work it shouldn't cost too much. All the other cylinders and rings looked great. I agree it should not happen to a low time engine and I guess I just have to take the blame. Feeling relieved to have found the problem. By the way I live in North Carolina and the shop that did the overhaul is located in Florida and was done by the previous owner. I trust my mechanic more anyway but he did say everything else seemed to be done properly. Thank you all for your ideas and help.

Yes , the engine is "wet" from some oil leaking somewhere but can't pinpoint an exact location without cleaning up the engine tomorrow. It's been like that since about 50smoh but was not too concerned till now. I only run 6 quarts so there is not too much in the case. Oil seems to get dark after only 5 or 6 hours now which I know is not normal. Guess it could still be a ring problem but I'll be waiting at the mechanics hanger door at 8am. Sometimes not knowing is the hard part. It really is great just having fellow Mooney owners to share things with when there is a problem. Thank you everyone.

So I went to the airport and pulled the plugs. No oil . They looked good. So I'll take it to my mechanic and hopefully we'll find the problem. Thanks again for all the advice. I'll let you know tomorrow whats going on. Any input is still appreciated.

was the oil blowing out the tube like mine? Hope I don't have to change them all . That would hurt.

That's what I'm hoping. Would explain my high oil usage as well.
