im having a problem with my 914. the oil light for my 1.8, keeps coming on. never when the engine is cool. but after it is good and hot. it will come on when get off the freeway and sit at a stop sign. it comes on when im hard cornering. it even came on once after i was getting on the freeway at wide open throttle then immediately decelerate. i am running 20-50 wt oil. and 800 rpm idle. and oil level to the top line. but the problem gets worse as the oil level drops. im not real familiar with the type 4 engine. but know the type 1 very well.
i have a couple ideas for where the problem may lie. 1. oil pump is wore out 2. windage tray, or lack of. its not a defective oil pressure switch, i replaced it with a new one with the same result. in fact, i now have oil light and an oil pressure gauge. im pretty sure this is not normal for a type 4. but i want to ask anyways, so i can rule it out. any ideas? |

I have often wondered why no one (among the engine builders here) never suggest a simple fix to the low oil pressure problem......just place a shim (washers) inside the oil plunger pressure covers. this will give a higher tensinon to the oil pressure springs, and results in higher engine oil pressure. I think SCATT even sells an adjustable (turn a screw) spring cover cap allowing really easy adjustment....The oil passages, gallies, in the 914 are very large relative to the oil pump size. thus typical low oil pressure at low RPM,s...Rule of thumb is 10 psi for every 1000 rpm,s.
