Chevrolet Spark Oil Witness Light helps ...

Hello greetings to all in the forum ... I am anodaded recently we rebuild a engine to a 3 -clindos 800cc chevrolet spark The balea caps and are good those of crankshaft were scratched a little and I do not understand why if everything got new ... I would appreciate an aid because before that we thought it was the oil pump and we also changed it because it did not have a year of having put on and turned on the light also now put on a new bomb and it is also giving that problem ... Thank you.

Hello, if we discard an electrical failure, I think it is best to install a pressure gauge and verify the pressure, if it is really low I would try the pump in a bank, if the test does well it is very possible that the leak is being given by the bearing of the camshaft or the axials, it has happened to me sometimes.
I hope my opinion serves you.
Cordial greeting.

Could it be for the crankshaft helmets ????

It is possible, it is difficult to know, if rectified and put on the caps that corresponds to the extent that the crankshaft is unlikely.
To be able to guide you better, it would have to have many accurate data, which is the crankshaft if rectified, measure of the caps, if adjustment with blue or plastigage was done, if the camshaft touched.
The possibilities are many, so I insist that the ideal would be to take the pressure with a gangster, to be sure whether or not there is pressure to begin with.

Hello friend, the engine was rebuilt with all standard, a new crankshaft, what I could see was that the crankshaft caps worn but I do not understand why it happened ... If everything was placed new, I will change the helmets and try again perhaps .. Who could have scratched in the first ignition of the engine when it started for the first time. No....????
