Thanks - that answers my question about my 20 PSI oil pressure at idle, hot engine.
 
Thank you for the information. Has anyone looked into the performance benefits (if any) of having the heads ported / polished, changing a cam bore stroke, or any other top end work? D3 has limited products for the standard XLR and I was interested in trying to squeeze out some extra horsies!
 
Am not sure but is the cylinder numbering start at 1 on the passenger side rear ond of the engine compartment with odds in the back and evens in the front with 2 also starting the passenger side?
