Clive,
I have another 2200 with the problem and its #2523. I plan to find the
guides local if Possible for I have the tools to do it. I hope to
contact someone to find out what spec material should be used if I have
to make them. The bronze material comes in many flavors. Also I will
have to determine the proper size for each valve when I get the heads
off. If I remember right you found that the VW golf had a similar size
guide. How did that work out? Will keep you posted and again thanks for
your reply.
Tex

Wow, that=99s a fair number apart from mine. Do you think that
they can have been supplying oversized guides for 270 engines?
What=99s your plan to resolve? Send heads to Pete?
I changed mine without involving Jabiru UK, was in too much of a
hurry, regret it now.
Thanks, Clive

Hi Tex, I read you posting about the valve guides. Do you have the
serial number of the engine?
Mine was 1460 and Christian says the Chilean one was 1482. If your
example was close maybe we can indicate and period that folk can look
out for?
Regards, Clive

Nick, thanks for the info. Have come to the same conclusion that the
guides were oversize for all the cylinders wore the same. Again thanks
for the info. Tex

Tex,
Here in the UK guides were found "worn" at less than 50hrs. Careful
measurement showed they were exactly 7.50mm bore, where the standard
guide should be 7.05mm. Looks suspiciously like human error!
Once the batch passed through the system, that particular problem
went away. Not sure what serial number engines were affected.
The majority of the oil fed to the heads is dumped on the inlet
valve rather than the exhaust which really needs it. Try to persuade it
to go where it would do more good - see Jabiru info on French site
"Contrails" for some ideas.
Nick

Tex,
Since you posted here as well I'll copy the response I sent to your
lightning-list posting:
Tex,
I gave you the facts as I have seen them over the years. I've sold a
lot of engines and very few valve guides. What do you want - some story
about huge valve guide problems that are not happening? I don't think I
misstated anything in my reply to you. This occurrence is evident in a
few cases around the world but not many when put in context of the
number of engines sold. In the USA when we hear of a valve guide issue
we fix it. If we should find a valve guide that was over size from the
factory we'll fix it at Jabiru's expense but we have not found and
engine yet with factory oversize guides. I do expect that I will find
one sooner or later IF there truly are engines with oversize guides sent
out by Jabiru.
Sorry to disappoint you in my response. I suppose I could have
commiserated with you and told you how awful your situation is but I
would much rather be honest and tell you what we are seeing and have
seen over the last 12 years. If you have a valve guide problem how come
we've not seen your heads here for diagnosis and repair? Do you want
the problem fixed or do you want to just complain about it.

Don't you just love it "putting things In perspective" . Thank God for
the web site we have to share our experiences. If "putting things in
perspective" is to completely ignore a question related to ones
products, don't seem proper to me. I have two Jabiru engines and a
Lightning,and I am directly responsible for the sale of two airplanes
and about 6 engines. I love the products from Tennessee and am really
disappointed by the responses from Pete. Its quite evident from the
others around the world *there is a problem* and with the help and Ideas
gathered here on the web site I am sure to correct it.

For those interested here is a picture of the rocker box with the cover
off.(as if you are doing a head bolt check) If you see the discolored
area around the exhaust valve on the right,you might want to look
further into the situation.

Discoloring around the exhauxt valve stem is usually associated with heat
come thru the valve guide and seal. I spent many years as owner operator
of an automotive machine shop as well as building a multitude of various
types of racing engines. I've ran across this many times
