Hey guys sorry to bother again now this time it's gone I have only two options either to get complete engine replacement or rebuild the same one things went wrong are crank shaft and rods. As referring to my earlier post about knocking sound from the engine bay. So yeah

A. am looking for experts opinion if we rebuild what parts do we need to use that is absolutely need to be replaced (crank shafts, bearings, rods, and what's else please keep in mind that most on the things in the head are new replaced before

B. If there is any selling aj133 5.0 N/A please please refer me




Thank you

 

Its hard to say what absolutely need to be replaced. Before you start ordering parts, you should do lot of measuring to judge is it worth. I would start by measuring the crankshaft and block straightness. For this you need good and somewhat expensive accurate tools, what in most cases are not worth to purchase if you are not overhauling engines often. Check an engine specialist on your area (exsample race engine builder or tuner) and ask how much they charge for measurements if you bring the components to their shop? (main bearing caps and bolts are needed as well -> These needed to be torgued on place for measure) Work wise its 1-2 hour job.
Then if crank and block are Ok, you need to make desission do you want to replace all wearing components, or just ones out of tolerances? You need to check roundness of the rod big ends and if i be that far in on the engine, i would remove pistons and minimum check the rings for carbon build-up or wear and maybe have a light honing for pots depending their condition. If the rod bearings have gone big time or spun, check piston heads very carefully for markings of valves or head. No kisses accepted between these parts.
Only thing for sure what is worth to change everytime an engine have had fail or risk that there might been foreing material in oil, is oil pump. Needless to say that the block, its oil channels and all oily areas and parts need to cleaned by high accuracy. Hint: Examine underside of pistons, because particles tend to stuck and hide there and wait until owner starts just rebuilded engine.

 

You did not post where your from? But from your name somewhere in the middle east? Maybe post the year as the basic 5.0L stayed the same but the bolt on stuff and electronics did change.
If so this won't help but I do see a complete 5.0L NA engine here?
$4500 and it's a 2010 but shipping will probably make this not work for you?
5.0L NA Engine

Right now there are 4 or 5 on EBay with different amounts of miles on them.
Here is another one? 75K miles and a six month warranty.
It's a good bit cheaper too?
Used 5.0L NA Engine

Parts are available too? Here is vendor with many new rebuild parts?
5.0L Engine Parts

This listing is only showing the SC parts but he probably can help with the NA versions as well?

Why would you continue to throw good money at a crap car? Forget what you've spent up to this point; that's money down the drain. Take stock of your current situation, and try to make an unemotional decision regarding a car that has proven to be junk.
I advised you last year to look at used Jaguars from your local dealer in Abu Dhabi. Right now he has a 2019 5.0 SC with 20k miles for USD$48K. If you've been following this forum, you know that this MY is the pinacle of the X351 line. The piecemeal approach your mechanic has taken hasn't worked. A rebuilt engine with a guarantee probably costs $20K all-in. Take that money, plus the scrap value of your car, and get something that you will be thrilled to own. If your mechanic is advising you to repair (again) your car, ask HIM to buy it, fix it, and resell it, if it's such a wise decision.

 

Guys thank you for the inputs I don't know yet what to do just am here stuck in an year I have spent around 30k$ till now on it and now it's alot of money to waste I do agree to scarp the car and put some more get newer year. Tomorrow I will go and meet with the guy (the mechanic) and update you
