Due to impending track time and my total inability to resolve the problem, I tracked down a local P-car mechanic who said he was very familiar with 914s and cut his teeth working as a mech at Vasek Polak. I figure 'what the hell, can't fuch it up any worse than it already is'. So he's got my car, checks out the pressure relief valves, inspects the bores, blows compressed air through the oil passages. Air goes, he doesn't notice anything fall out. Check valves move freely. We both agree he should put in oil, new Mahle filter, and give it a whirl.
He has a pressure gauge hooked up on the engine to see what happens. I wasn't there, but apparently his gauge only goes up to 100#. It pegs shortly after starting the motor (2.0L) and the Mahle deforms just like all the other filters and oil pukes all over the shop floor. Oil was Castrol 20w50, car was inside a heated garage so temps were probably mid-60s. He's stumped. He calls someone out in California (I didn't catch a name) and both of them are stumped. (IMG:style_emoticons/default/headbang.gif) Oil is getting picked up from the sump and pumped into the filter. Where is the next stop after oil leaves the filter? I've seen the diagram in haynes and find it not very helpful. Any ideas on what is wrong? |

Exploding oil filters on start up is a real messy PITA. I had the same problem happen to my freshly rebuilt 2.0 l race motor. This was a full flow system with a remote oil filter setup using a 30mm oil pump and a front oil cooler. I went thru the process of checking the pressure relief valve and made sure the springs were correct It only takes a few seconds to dump a lot of oil. I started using a Fram HP 1 filter and kept the rpm's down on start up, which seemed to help the problem. I still wasn't happy with the arrangement so now the engine is out of the car for a complete inspection starting with the oil galleys. Will know later this month if the oil galleys are the culprit.
