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? |

ok i have some new numbers. just to answer a few questions. the sender is a new vdo 2 post sending unit. one for the idiot light the other is for my digital oil pressure guage. no sealing compound was used. i installed it dry.
these numbers were taken today on my way home from work. it was hot. 91 degrees here in so cal. here we go..... at 3200 rpm oil pressure 39 lbs cylinder head temp 318 oil temp 212 at 900 rpm (idle) oil pressure 13 lbs cylinder head temp 308 oil temp 212 this was after a 30 minute freeway drive at 75 mph. and for those of you wondering how i came up with my numbers, i built a whole new dash with all dakota digital gauges. |
