So I'm in.
It took a meter long breaker bar and wrapping the belt around the pulley to crack the bolt loose.
Probably close to 300lbs+ of torque maybe more. The bar was bending almost 20* before the bolt gave.
Removing the Pulley was easy. Just wiggle it on all sides with a smal crow bar.
I need to re read the procedure for removing the cams again.
You need to put a small Allen key in the Intake cam and have it fully advanced then undo the bolt.
Once the front of the cams are loosened you remove the timing chain.
Then the cams can be removed and I can access the head bolts and remove the head.
This will allow me to see the pistons and valves.
Now if I can use this to compare against my head and can confirm or deny valve damage to my engine.
I would also have 2 sets of part to pick the best ones and replace.
Next is the trans.
I'm going to remove it at the bell housing. Now that the engine will be significantly lighter ( and I have access to the mounting points it can go on my engine stand..
Then the bottom end comes off. I can inspect the con rods for any play against the crank
If there is damage to this used engine I'll be talking with the seller again. Good thing I've only paid 1/2 at this point.
I don't expect any, but then again he said it was rear ended and I can see signs that there was front impact as well.
Also starting to doubt the kms. My engine looks better externally this has oxidation and topical rust worse then mine.
Could be a sign that it ran at very high temps. Like the alternator looks twice as old as mine. Looks can be deceiving tho.
