CHIPSHAPER

Hi Skip thanks for the responce as you know, it gets frustrating when everything you do ends in oil everywere! I will take some photos of installation today and send to help understand. The oil pump is part of the engine. Regards Paul P.S. have hopfuly sent this to you as PM also.

Hi Skip, Yeh its a bit of a poser for me too! Header Tank, feads oil pump. Sump feads oil cooler. Oil cooler feads header tank. New pistons, valves,springs, guides and re-bore. Blows seals!!!! Paul

10/40 oil now. Pressure regulater checked. Blows the seal out???

FSM= Me Dumb! Thanks. Ref 20/50, at tick over only 4bar, and not got to operating temp yet because of pressure. Paul

20/50 oil. Bypass... OK ill look at that this weekend, thanks. Sorry........ whats FSM? Paul

Thanks for the tip and I have been assured that they were lined up. any more Ideas please!

Hi Guys I said I would report back. Ram supplied new pistons valves seats springs etc, and the engine was re bored and assembled. It sounds very sweet now………..But……………… the oil pressure is off the clock!! On tick over it reads 4 Bar, but as soon as you rev it the pressure goes to 10 Bar and starts to leak oil from the crank seal. Any Info would be great as now I am desperate!!!! Regards Paul

Just thought I would let you know have purchased re-build kit from Ram Engines and will post results as soon as. Paul

Yep thats the one, just north of Birmingham. Thanks for the info!

Hi, Does anyone Know where I can get new pistons Etc. for a EA81 engine please? Regards Paul

Took it to be sripped todayand I will let you know what is found! Paul

Had a good long look at the engine today and when looking inside through the spark plug holes there was a visible amount of oil in the chambers after it had been run? Paul

I dont know either BS, but its worth a look. I think I will take the heads off first and have them checked and if its not in the head at least Ive started the strip down. Thanks Paul

Thanks guys, The engine was standing (well preserved for 12 months) and I replaced the seals before fitting and constantly check for leaks= none. The oil is held in a tank and pulled into the sump.It vents into the top of the oil tank and there is a overflow tank that then vents to the outside. The residue underneath is a black smoky oily film all over the fibreglass undersideof the aircraft. As I have said there is no visible smoke apart from first rev from tickover and then it is just a puff of smoke, and the plugs are dry and good colour. Yes I agree the oil consumption tells me something is wrong and I think It is approaching a strip down. I have spoken to Ron at Ram engines and he can supply pistons and rings to fit so I really am stuck as to what to do at present? Paul

The cowles are removed every flight and the engine is bone dry. The only sign of oil is on the underside of the aircraft in line with the exhaust outlet. I am begining to think it must be rings even though they were replaced with the pistons (+.020) 40 hours ago. Paul

Thanks Guys, I will try a leak test this week and let you know. The plugs look great! Not oily at all. Yes wish I was good enough to scywrite. Maybe it needs running in? but when its using this amount of oil its a bit scary up there! A freind flew behind me this weekend and could not see any smoke at all? As I said the engine runs real strong. Paul

Grossgary, No oil in coolant. Its realy bugging me now as I dont understand how I get good compressions on all pots (160) and Its not smoking, have replaced valve oil seals on all four, but the oil usage this weekend was still 1 ltr per hour? I was hopeing I had missed something basic and you clever guys could point out my mistakes. Paul

Sorry to interupt but you guys seem to know EA81s and i have posted in "EA81 OIL BUCKET" with little response? I have an EA-81 in my aircraft with a dry sump, and it is using oil at 1 Ltr per hour! The compressions are all on or around 160 and it was reboared 40 hours ago with new pistons and the heads re done etc. We fitted new valve oil seals but it still drinks oil! Any help or advice would be greatly received. There are no oil leaks that are visible but there is oil like residue on the bottom of the aircraft where the exhaust exits. It has no PCV or head breathers as it breaths through the oil tank. Regards Paul

Any suggestion, (Scrap It, Burn It) Paul

Thanks Jerry, but it is a dry sump and has no PCV valve or head breathers. I yhink it breaths through the seperate oil tank? The engine is completely dry and runs stong, it just blows a puff of white smoke when you rev it from tickover. Paul

Thanks GD, I have soaked the boars in thin oil for a week in case the oil rings were stuck. The engine runs great, it just drinks oil and I was hopeing someone would know of a reason. Could the oil rings be wrongly fitted? Paul

Sorry to re-post but cant work this out? Hi All, I have an EA-81 in my aircraft with a dry sump, and it is using oil at 1 Ltr per hour! The compressions are all on or around 160 and it was reboared 40 hours ago with new pistons and the heads re done etc. We fitted new valve oil seals but it still drinks oil! Any help or advice would be greatly received. There are no oil leaks that are visible but there is oil like residue on the bottom of the aircraft where the exhaust exits. Regards Paul

The engine is dry sumped so I think it breaths through the oil tank. Paul

The valve covers do not have a breather and the engine puffs a small amount of white smoke when you rev it from tickover but the plugs look great. Also there is an oily smoky residue on the underside where the exhaust exits. Paul
