2007 VIN D specs ....

I`m not too good in hemi`s engine

I have a 2007 2500 RAM 4x4 with a hemi 5,7L ....( 56,000 milles )
It has what seems to be a noisy wrist pin ....

I will order a new piston & head gasket set to fix the problem

Does this engine have MDS ? Would my 6.1L 2006 SRT8 cam fit in it ....

anything else I should know ?

thanks

Dan

Welcome to the herd, you've got good toys.. are you certain it's a wrist pin? Broken exhaust bolts can make a lot of noise often confused with mechanical noises.

thanks,
I heard that lots of those hemi`s have lifter/cam failure too ....

Since you work a lot of these , did you ever have a wrist pin failure problem ?
(yours or customer )

Never a wrist pin always either loud exhaust leaks or bad rod bearings on the crank yet to see a wrist pin fail.

How far has it been driven while making noise? If it is any distance at all it won't be a a rod bearing. They usually let go fairly quickly once they start banging. Maybe use a rubber hose and probe around the exhaust Manifold to try and locate the source?

I have a stethoscope to locate the noise ....


when I first started the RAM at the auction it sounded like an emptied lifter

But after driving it home ( 6 milles ) it sounded like a wrist pin
idling , unloaded ( going down rpm )
I gave it the real test ,,,,went on road floored it to 55000 rpm for 30 seconds in trird gear accelerating ...

back to idling still real smooth and that ticking ratling clear noise ,,,,,
rod bearing has a definitive regular noise ....

went to two other mecanic friends that both work at RAM dealers
oupsss wrist pin Dan ,,,,got to open it up !

Ill first look at the top end ( rockers ,,,never know , but i doubt )
It aint an exhaust tick ....

Dan
