2006 M45 engine

[Tyrick22]

I have a 2006 m45 I bought from a friend. And he assumed the engine was blown I just don't think so is there anything I can try before I buy a used engine.. i checked the oil it was pretty low the camshaft sensor had oil gunk on it i replaced battery and when I try to start the car lights come on and make a thump sound any suggestions I can try would be greatly appreciated

Can you record video of what is happening? "Thump sound" is rather vague.
In general:

• Bad battery, starter clicks
• Bad starter, starter doesn't make a sound
• Locked engine, starter sounds like it's obstructed. The kind of motor noise when your blender is jammed...etc

What is the condition of the replacemwnt battery anyway? Is it new?

Combine that with the fact that the oil was low and it wouldn't be surprising that the engine is damaged.
How low exactly are we talking? Second hole on the dipstick low or not even showing on the dipstick low?

Second line on dipstick low and yes sir the battery is new but has been sitting in the car for about a week it act as if it wants to start it spins but die out and make these clicks

I don't see anything inherently wrong with a Walmart battery, as long as it has the correct rating. 720 CCA
After watching the video, I'd encourage you to test the battery (rare, but some fail right out of the box) or just jump the car as you attempt to start it.

2nd and probably more importantly, put a 19mm socket on the crank pulley to see if the crankshaft will move freely. It rotates in a conventional direction - clockwise while standing in front of the grill/counterclockwise from the driver seat.
If you stand in front of the grill and turn it counterclockwise, it should turn the whole pulley. If there is so much resistance that you need a cheater bar, or the bolt comes loose while the pulley stays stationary, then you have a locked engine.

If it turns by hand and still won't start with a jump, then your starter might be weak.


2 further questions:
1. How many miles on the vehicle - did I see 253,xxx on the odometer?
2. I understand you want to verify before committing resources to the project. What made the previous owner think that the engine is blown that is not obvious to you?

Thanks for the reply here is the link to turning the crank https://youtu.be/gJjr_UHJ7ss
Also I tried to start it and this is what it does https://youtu.be/fhKtv5RnCyMI have brand new battery what could it be

Well, good news is that it turns in the normal direction. Very notchy, but it turns,
there are some questions I'd like to clarify. Could you please address them?
1. The battery seems like it's trying. Did you try to jump it? Is it the same "new" one you tried with yesterday or is,it another?

2. Does the crank turn as easily when you go the other direction?

3. What info/knowledge did the previous owner have to make him/her think the engine is toast?

Does it act the same way with everything connected? - air intake tube and MAF sensor electrical plug as well as the crank and cam sensor

[Tyrick22]

Honestly he said the oil was low he tried to change battery and I believed because the oil was low and the inexperienced people he had to look at it came to that conclusion I buy cars and replaced the motor I feel that it's not the motor could be wrong also I went and exchange the battery out for a new one last night and had them test it before I left it just act as if it wants to crank but something is stopping it and the crank turns freely both ways

[EdBwoy]

So, the battery in the last video is the 2nd or 3rd replacement, got it... Have you tried to jump the car?


Also, in the video the black rubber tube going to the throttle body is missing. I don't know if it's been disconnected all along as you tried to start the car, but I suggest you connect it and check all the engine electrical harnesses.

Any updates on this?

[Tyrick22]

I was looking to check the battery cables, starter or alternator but it only try to turn over
