Asked by Mar 29, 2016 at 06:46 PM about the 1994 Honda Prelude 2 Dr Si Coupe

Question type: Maintenance & Repair

I have a 1994 Honda Prelude SI h23a, just finished
doing the head gasket, timing belt, water pump,
cam seals, and all other top end gaskets and seals.
. 964 miles of easy smooth driving, oil never
dropped a hair,  so clean still. . Oil light flashed for
2 min at 735 miles,  oil level was the same,  no
leaks anywhere,  motor is spotless.. at 964 miles I
had stopped for 15 min to get fast food, when I left
I seem a puddle of oil,  car still running I looked
underneath and seen oil POURING from my timing
cover.. turned the car of and towed it home :(...   
friend said cam seals and check oil pressure
sensor..  is this correct?

You will know when you tear the timing covers off.


If that cam seal did not seat just perfectly during the rebuild...after a relatively short duration of operation (esp. if it gets pushed), the cam seal is often the first one to show. And just look...how high up is the leak? Obviously the cam is up high...and that was one that was replaced....say no more. Cam seal can become slightly warped when you try to place the valve train journals over her...it is a bit of a juggling act...just a thought and good luck!
