Old Fella, another question with hydraulic lifters. If engine oil pressure gets low due to very low quantity, will it affect the valve operation? The reason I ask is recently I lost most of the oil overboard in a Jabiru engine, but it was an old one with solid lifters. It kept running even though the oil pressure was down to below 30 psi and has suffered no apparent damage. I wondered what my fate would have been with one of the later engines with hydraulic lifters?
Pardon my ignorance, but I grew up on old inverted inline and radial engines etc, not these new fangled things. As long as thre was some oil, they ran fine.
