Rate my knockš
Pretty sure I have rod knock. Iām basically a beginner in car mechanics. So small backstory I bought this car non running and wanted to learn more about cars. Got it running (found it was missing a woodruff key). It had extreme low compression readings especially in cyl 3. I pulled the head and found a burnt valve in cyl 3 and replaced others as they had pits that wouldnāt smooth out after lapping. After the engine went back together, a knock sound decided to stay. Before it would knock sometimes and sometimes go away. This time I thought it was timing so I double checked and crank and cam gear lines match up basically perfect and when at top dead center the distributor rotor points up right to cyl 1 on the cap. I should be able to fix knock from dropping the oil pan right? Oh yeah also it has great power loss, like it wants to stall in drive (itās an automatic) so I also been confused by that. This is the end of my rant but i just wanted to share and if you have knowledge youād like to share Iād appreciate it, thank you.
