Make sure you have the correct sensors. The sensor by the oil pump should be a .9 bar. This often gets confused as even some of the Microfiches show a 1.8 bar sensor. Another problem can be corrosion in the wire connections or a bad wire to the sensor. Check these carefully. I've seen people change engines for no reason. Last thing would be to check the oil pressure with a gauge. Should be able to obtain ~10 psi/1000 RPM. Slightly less if the engine is hot.

I have an 87 Synchro Westy with 153,000 miles on it. I was told the heads had been reworked at about 120,000. I started getting an oil pressure alarm below 3100 rpm after the engine has warmed up. I replaced both oil pressure sensors, and just finished replacing the oil pump with a high volume pump from Bus Depot. I still got the alarm after then engine warmed up. Bummer.

A mechanic friend of mine says that my main bearings are probably worn to the point that there is too much clearance. About ten years ago I rebuilt a bug engine. I remember having to have the case line bored. Of course, this required OD bearigs. Is this common with the 2.1 Wasserboxer? Has anyone out there replaced the main and camshaft bearings without having to rebore the case?

If I do decide to rebuild, what other pitfalls should I look out for?

Maybe now is the time to look for that Subaru engine.
