Check for play in the distributor sometimes the slop will make the pick up window under the cap will hit the distributor cap , the squeaking noise may be your belt or tensioner pulley bearing the knock can also come from a bad tensioner as well .

Knocking noise in my 92 toyota camry and cant move in drive or reverse


It sounds rather like one of the drive shafts may have broken, but that is rare. What happens when you rev the engine in neutral, any knocking noises then? Does the oil pressure warning light come on? Is the check engine light on?

I'm trying to deduce whether the noise is in the engine or transmission somewhere.

How to tighten /loosen belts on a 2000 xterra, its making a super loud squeaking noise when i turn on the car


The only cure to fix squeaking belts, is to replace with the new one. When the belts start squeaking noise, then it is the time to check the status of the timing belt or chain, depending on the size of the engine.
The 2000-2004 Nissan Xterra was offered with the choice of 2.4L 4-cylinder or 3.3L V6 engine.
The 2.4-liter 4-cylinder DOHC engine was a pretty good reliable engine, but for this truck, it was underpowered. This engine has a long-lasting timing chain - there is no timing belt to replace.
The 3.3-liter V6 SOHC was also a bit slow on pick-up, but for daily use, it was pretty good, durable, simple engine. This engine has a timing belt that needs to be replaced at recommended intervals. The SE model offered a supercharged version of the same engine with more power.
To get more information, please read my tip :
When should I change the timing belt on my car?

Mitsubishi 3L V6 engine knocking.


The knocking noise has to be a deep knocking noise if its the crank bearings . If the oil is very gooey the oil was never changed properly at the mileage or months as required. Also if the oil is thick as you state it must have 15,000 miles or more on this oil. 10,000 miles the oil will still be thin if never overheated. I suggest this engine be completely disassembled and inspected if you plan to keep it. You will find wear to more to it especially the cam shaft, lifters, rocker arm as so on. for the oil never lubricated the engine enough to save this engine

Sounds like you didn't put the pushrods back in the proper locations. There are two different lengths in this engine and you may have one backwards
