Thanks for the replies. My mechanic is out of the country at the moment and I am a long way from another one. Just looking for some advice as to whether it's an immediate safety issue or not. Thanks

Hoping for some suggestions here. My PA38 with Lycoming O235 has progressively become harder to start. It needs up to 10 primes from cold and even needs a prime now when warm. The impulse coupling was changed a while back for a different reason and doesn't appear to be the issue. I am...

Thanks Dan. It sounds like the problem is in this area. Is the ball seat replaceable or repairable if corrosion or pitting is the likely culprit?

The bearings were replaced but the crankshaft wasn't touched as it looked like new. We will try a new ball and spring and then go from there. Thanks for the advice.

After start the oil pressure rises to about 65-70 psi at 1000rpm. After landing with a warm engine right back at idle it is in the yellow band at about 40 psi. A touch and go on a warm engine will bring the oil pressure up to 95-100 psi and on downwind at cruise power it will slowly start...

The tomahawk doesn't have an oil cooler which can be an issue in hot weather. The oil pressure rises above normal occur whether the engine is at normal operating temperature after an hours flying or shortly after start up. It always returns to mid green on the gauge after a while when power is...

Some great suggestions. We have connected a direct reading and correctly calibrated oil pressure gauge to check the accuracy of the panel's gauge and it is accurate. Changing the ball and spring sounds like a good place to start. The engine wasn't fully overhauled as it only had about 300...

Thanks for the reply. The first few hours after the rebuild the oil pressure was too high and that was masked by a faulty oil pressure sender which was replaced. A couple of washers were removed from the oil pressure regulator and that brought the oil pressure down to normal levels except in...

Hi everyone. I own a Tomahawk with the Lycoming O235 engine that was rebuilt about 50 hours back with 4 new cylinders and a new camshaft and conrod bolts plus various other parts. It runs beautifully with all normal indications other than the oil pressure. With a warm engine full static...
