I need help my m42 spun a bearing

[M4202]

It rod nocks really bad now . Anyone know of a good trustworthy mechanic that works on the m42 ? In DFW i dont have the energy to rebuild the motor .

 

Any help would be appreciated.

I'd go engine shopping.

 

The M42 parts have long been stupidly expensive,

and IF you can find a used engine, they're tough,

and usually last a long time.

 

Did you have an oiling issue?  Thrust bearing?

Yea shopping. Or was there something special inside? No? Then off to the neibourghs pool & ”new” in the hole.

200k mile  motor that was needing a rebuild i was trying to avoid it . if im going to spend the 2k on a used motor 

thats going to pop again . i might as well do it right and send the motor to metric mechanic in minnesota and have it done right .  Ha yea  this 02 just doesnt want to run right or at all . On the bright side 

it will be a 2l again.

Also a crazy idea E39 m5v8?

anyone done that ? 

 

or get a v10m5 e60 motor with a stick 

 

?

V8 and v10 swaps have been done. Web is your friend.

..but classical physics is not.  A v8 fits just fine, until you want to put manifolds and plumbing onto it.

Then things get... cramped.  Quite cramped. 

Hmm.  I wonder if a 'hot v' would work...

It's all do- able, but it's off the old Pelican Auto Parts banana scale...

 

There were 3 M42/m44's in the cheap, friendly yard

up the road from me last week- they usually get $250 for a complete

engine with accessories.  

 

And I've not taken good care of the 2 M42's I've had, and both have held up fine-

you can buy quite a few 'gamble' engines and not be up to the cost of a complete

timing chain set with guides and tensioner rails.

finds the theory of the M42 attractive, but the practical aspects to be... expensive beyond their merits.
