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? |

thanks for all the input everybody.... as a bandaid, i turn the idle up to 900 rpm. and here are my new numbers.
rpm set to 900 cylinder head temp 300 degrees oil temp 210 oil pressure 13 psi at idle no light at idle now. but the real test will be tomorrows drive home from work. hopefully this will buy me some time. this way i hope to find a good engine core to put on the stand for a proper build. so if anyone has a cheap 1.7-1.8-2.0 laying around i am in the market. emphasis on cheap. LOL. thanks again doug |

LOL. thanks again doug The oil pressure may be as low as 7PSI at idle, when hot. The idle speed for a stock T4 engine is SUPPOSED to be 900-950 RPM. While the oil temp is a little high, it's not really an issue here. You said you have a new oil pressure switch. Are you SURE you have the correct switch? Many non-VW specific switches don't have the correct pressure trigger point. The Cap'n |
