I thought anything below 110psi was bad? How the dickin's was it still running? My 3.5 has 140-150 except for number 7 which is 160 for some reason, but as stated, it's poor oil changing regime that has destroyed that engine. A chap at RPI told me to always use engine oil with a high zinc content as it helps to preserve the hydraulic tappets against the forces applied to the cam and vice versa, so I change the oil every 3,000 miles and I have never had a RV8 get the rattle of death yet. Actually the above statement is bollox, I've changed my oil twice in 12 months and covered 900 miles, doh.
First thing I do with any RV8 vehicle I get is remove the sump and clean out the sludge if there is any, and clean out the oil pick up strainer, and then worry and fret about maintenance regimes, still, it gets me out of the house
