    My 1/2vw built by Scott Casler had oil pressure over 80 PSI when cold. Once hot or at operating temp oil pressure was around 60psi. Normal oil temp on this engine was 160 degree's. A little to cold for my taste but it is what it is. Mine also had an oil filter. This was the style oil filter that was mounted to the oil pump. Scott installed this.
    I had some oil pressure issues at first. What was found I was over filling with oil. The cam gets in the oil and will make the oil foam if the level is to high. It don't take much to over fill one. The 1/2 vw don't hold much oil. A sump would be nice for this little engine just for this reason. But this is another subject for another thread.

    I have a cooler and remote filter on order from Scott. When it comes in I will install cooler and filter; check & clean sump screen; change oil; then fly again. Got 4 hours on engine (and UltraCub) now. Thanks for the info. Dee

    A 1/2 vw don't hold much. Two quarts and it is almost over full. I found on my dip stick the oil level had to be right between the low oil mark and the high oil mark. Scott can give you the exact amount needed for the 1/2 vw. But it is not a lot.
