I have a 1994 corvette I bought with 160k on it for less than 4,000 and it ran great. One day after giving it some love oil change air filter oil filter fuel fllter and some grease for the rear diff. I drove to autozone for I cant remember what shut the car off and walked inside. I came out turned the ignition car made a loud screeching sound I immediately turned it off because the day prior I heard a similar sound when my 2008 milan show car had a expensive fluke failure. Fluids full it burnt up the top cam in rear cylinder head.

After that I had it towed and it started sometimes it had a knocking sound to it at first it was at idle, I noticed there was no oil getting to the top end so I got a new oil pump and eventualy gor the medal link rod to go to the motor. This car does not have the distributor but the omnispark. Now the oil is getting to the top end however it was leaking out after a few bouts we found the cause of the drastic leak and slowed it down , because it could loose all the oil in a night but it could also go days before it dropped the oil.

Now my car will not start but the starter was tested and is good the ignition switch activates all the pumps and electronics but no sound not even a click. when it does start it has a tick or knock above idle oil pressure, is very strong.

The strangest thing is the knocking stopped i drove it a short distance then it started again. it was random and happen more than once. there was a time it did not knock on the jackstands but knocked again as soon as we put on the ground. the thing with the starter happen slowly it didnt just stop working.

I checked the flex plate etc and nothing looks broke cracked or loose. the knock is in time with the revolution of the plate. everything looked good under the oil pan nothing looked bad no discoloration or cylinder wall damage. push rods seem solid no chatter. there is play in the gear the oil pump arm attaches to under the cam but that is expected I was told. it tends to sound like its coming from the back side of the motor outside but inside it seems like the front of the motor. any ideas?
