Just replaced mine with new rod bearings and sealed power pistons and it runs so much better and quieter! Love it!!
I need a Tran for a 99 4×4 aw4 xj
I'm going to order a set of pistons and do this. 2000 WJ and my daily has a 4.7 with a rod knock that I can't afford to fix.
You could just film in your shop and not use your lift just saying I did like hearing the birds though.
I found another one of your videos about a week after a piston my 98 fell apart. I wish I knew. I’ve been following you ever since.
I need a head 🙁 for a 00 xj
Ah, my 1996 XJ with 384,000 miles makes a completely different, quieter ticking noise that goes away pretty quick. Whew!
59:40 Not sure if it's 100% accurate, but it seems those nuts are Mopar J4006385, which are – from what I'm able to find – are a 11/32"-24 nut.
ARP sells them in packs of 1, 2, and 10 as either hex or 12-point nuts.
The hex nuts are 200-8603 for a single, 200-8623 for two, and 200-8633 for ten.
The 12-points are 300-8373 for a single, 300-8383 for two, and 300-8393 for ten.
Hope this helps.
Put some rubber hose over the rod bolts keeps from nicking the crankshaft.
Thanks for sharing your knowledge and experience man, that's very generous of you
My ZJ does not have that kind of slapping sounds, rather a diesel-engine kind of rattle, I think it could be the timing chain. Are you planning on doing a driveway mechanic video on that too?
Pistons could be made by different Manufactures some may be better quality.
Just rebuilt my 1995 4.0 engine, and it has developed exactly this kind of slap 2 weeks after on cylinders 3 and 4, workshop took it back and repaired, new pistons, etc… on e again 3 weeks later, the same… is it bad quality parts? Bad assembly? Or what?
Sadly I'm not in the US so I cannot order from you since import cost would be crazy high… But please help me solve it…
Would pay good money to have this guy rebuild my engine..maybe next year
Hey Dex, any salvaging the block if your 4.0l overheated and pistons deposited aluminum on cylinder walls? I have the head tore off and am wondering if i need a new block or can use it still.
Shooot I been waiting for this love the humble back to barebones approach to fixing these issues. but why not just do it in your shop without the lift?
What about the older guys? 90-94?
I have an 01 xj a 2 dr sport the 4.0 slaps ever start up then go quite , so it's the piston thanks tearing it apart see wants it is .
I have this issue at 320k miles. Trying to decide if I should replace the pistons or just build a full new block
Perfect time long for this to come out planning in doing this soon I will probably pull the entire axle out though so I have a bit more room
