I was thinking last night would it be great if CAMIT cam up with cross flow heads for jabiru engines that is intake On the top of the heads not from under as they are now. Would alimenate different cyl temps I am sure? I know Camit would be the company to make them. They would sell like hot cakes.

Landing is mandatory ....... I like that quote,

Yes I believe Rotec have changed there way of making these LCHeads but that does not help me. If he would have done more stringent testing instead of just running the engine for a few hours. He should have come to the party and gave me 4 new heads?????. But at the end of the day I would not have anything from his shop on my aircraft. The later ones are not machined fron a billet like jab heads. Cheers Nev

CHT gauge how can I check if it reading right I put the end in boiling water it only showed 100 deg. Maybe it does not register in water the right way. I would think it would read 212 deg F.

Hi mike how many hours have you done with LCH on I can tell you for sure when you remove the heads those lower water pipes will be seized in and no they never leaked water. Yes no heating problems for me but I will never fit them again to much trouble.

I was surprised Rotec did not copy jab heads they have a coller on the guide so the guide can't move down, but that does not mean you can do shoddy work over drill the guide holes and still fit the guides in. I would never buy aftermarket parts of these small so called company,s I have seen Camit factory so professional trust them 100%.

Hey Mike cast iron where did you buy them from never heard of cast iron heads for jabiru??

I have all the parts for LCH conversion 2200 jabiru twin water pumps radiator all fittings ARE YOU GAME ??????

Hello Mike How many hours have you done on the LCHeads, I think my head tension was 20 I think as recommended. I tryed over size orings and sealant the oil leak must have bean coming from some where else. My heads where from early batch nothing but problems. Have fitted air cooled heads back on I find it hard to beleive you have no problems if you have read my other thread 4 loose valve guides I would be checking yours if I where you.

Maybe they melted down coke cans to make my heads, if the jab heads where over heated that may happen my air cooled heads are ok.

One last thing I will add the heads are soft the lower head stud as it is tenchioned it squashes the hole when it is unscrewed you have to unscrew it all the way as the hole is smaller. Some of the other studs are like that to when I take the heads off I had to re drill the holes but it done the same next time I removed the heads.

geoff I can tell you for sure I bought them leaked oil right from the start have removed them aircooled back on looking for a big rubbish to throw them in. They are a great idea for cooling maybe he should sell the idea to Camit he would make them properly.

Dazza I am new to this site what is your quote (I give up) ????????

Sorry I should have also said the early first hydrolic lifter engines still had the solid lifter cam. Cheers

Just to throw this into the ring I have a first hydrolic lifter 2200 engine with the shevy lifters done a bit of brain nutting and found i could strip the hydrolic lifter and machine a plug and insert it into the lifter making it solid. I replaced the rockers for adjustable ones and last I sent the push rods to Camit to be shortened by about 4 mil I think. All works well so far but remember the rockers are left and right for each cylinder. Bill from Bunderberg gave me a set of rockers when checking the rockers ended up with 2 right handed rockers thanks Bill again for the rockers. I bought one from Jabiru wow cost me about $50 bucks for one no adjuster. So reverting back to hydrolic lifters can be done at an affordable cost and camit will sell the kit for around $1000 I think.

I have a 2200 jabiru one thing I must say it never leaked oil until I fitted LCHeads.

Thanks from the start had oil leaks the top water flanges hard to stop leaking. After about 230 hrsOverhauled the engine, was getting hard to start found 2 of the LCH had loose valve guids one guide was moving in the head. They had over borde the holes for the guide but they still fitted the guides bad workman ship. I have run the engine goes good but can't stop oil leaks I believe the heads are porous. They are not replying to my emails I refused to send heads to them for repairs after what they done to these heads had them repaired local with my supervision. Cheers sad to have to tell you the problems as they work very well.

Hey bexrbetter the idea of LCH for jabs is good just the guy who made them is the problem.

Talking about LCH I fitted them 2 years ago had so much trouble I am putting aircooled heads back on.

Try applying brakes after lift off if it stops its wheel balance

I dont know if it has been posted but check your aircleaner eventhough it might look good it has to be replaced every 50 - 100 hrs the carb heat will bugger it

Any jab owners out there who have LCH from Rotec

how do i use this site
