There should be only 1 oil fill cap on only 1 valve cover. You just pour it in slowly.
Usually on one of the valve covers attached to a rubber hose going to the emissions system. the valve covers are the "upside down bread pan" looking things on both sides of the engine.
Open the hood and stand by the right side fender. You are now standing facing the FRONT of the engine. Look at both valve covers ( V8 engine 2 valve covers ) . The cover that ENDS ( nearer to you ) is # 1 cylinder. Dont matter what kind of V8. Closest valve cover end to front #1
.16 of an inch both for intake valve and exhaust valve [cold]
You didn't say which engine you have so lets go with a 4.3 V6 first. On the 4.3 they are located on the side of the engine below the valve cover. On the V8's they are located under the individual coils in the centerline on top of the valve covers on both banks.
yes both the 8 valve and 16 valve engines are interterence engines
i do beleve it should be in frunt of valve covers both sides. if not just flow the spark plug wiers from moter
It is called a "knock Sensor" it is the one that advances or retards the engine timing as needed, usually is green in color but there could be other colors and it bolts to the side of the cylinder head in beetwen both heads thank you The igniton coils are the items in the middle of the valve covers.
Removing the valve covers on an E series Ford van can be a challange. I have read many accounts where people are suggesting raising the body off the frame or removing the engine. Yes, these are effective ways to access the covers but easier said than done. The fastest way that I found is to support the engine with a jack and remove the motor mounts on both sides. This will allow the engine to drop down a good inch or more and will allow you to remove the covers with a little twisting and turning. A tip to make it easier is to remove the bolts and groumets from the cover as they tend to hook on things as you pull the covers, also you have to pull the covers out the front of the engine as the cam gear is in the way. Good luck, jims grey garage.
If it has oil caps on both valve covers, you can use either.
If the valve timing is correct and there are no damaged engine parts (or weak/faulty valve springs) that should not happen, yet however if the engine is "over-revved" the valves could "float" which is not normal operation. (If the engine is an interference engine there may possibly be engine damage.) That is normal and it is called valve overlap.
0.40mm both int & exh.
.16 inches both intake and exhaust valves
