The reason that I chose the Eagle Premier PRV was out of nessesity. There are only 2 PRV motors here in town, at the junk yards. Vegas sucks when it comes to being an automotive hobbiest, and this is a prime example why. It's the same salvage yard that has both PRV's, and they've never even done a compression test on either one! So who knows what the condition of the engines are, except to say they're over 91K miles on the clock. After I ran thru a couple of quick pictures on the Eagle Premier books, and wiring diagrams that I have here, that too is when I discovered that there is no pick up for the distributor. Just as bad, I have no idea what the difference between the crankshafts are. So even if I could swap heads, and cams, I have no idea if the connecting rods, and the bearing assemblies will even fit between Eagle/DeLorean. Another thing was checking the archives, someone had come up with this idea before, and it was *estimated* that the compression would result in 9.5:1, or so. I have no idea if that would result in bad vibrations, with an odd-fire engine. Currently, the engine runs just fine. No loss of power, oil pressure looks to be the same, and no decrease in gas milage. Exhaust is clean, with no smoke, or steam. But the level of oil inside the crank case is the same. Despite a bad leak from the front main seal. So while I have not performed any tests on the motor, I don't think that a simple head job is going to heal my engine. I think that the water jacket has been compromised between the block, and the cylinder sleeve. As you can guess, I am very worried about the internal condition of the motor. I have no clue as to WTF this crap is thats puking out of the breather cap. And that makes me worried as to what the condition of the oil passages, pump, and my valve train in general are, let alone my bearings, thrust washers, and crank. Back when I first discovered this issue, Warren @ DMC Houston told me that due to the description of my motor, it didn't qualify for a performance upgrade. I could only get a crate motor installed. So that hasn't exactly built up any hopes for salvaging this engine. -Robert vin 6585 "X" To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
