Tractor sounding '02 - Help!

[stephers]

cracks don't normally happen where the head gasket burnt thru     Check from ex valve seat to cooling chamber, from ex valve seat to spark plug hole and from ex valve seat to intake valve seat      Really check for head being flat and straight  

 

Thanks, Rick

Looks OK head has tiny little scratches,

Yeah, not really tiny, not really Ok. Like kbmb02 said: "Those scratches start a path through the fire ring"

The  scratches need to go, a total weak spot in the worst possible place.

Your head needs to be skimmed.

You already received a new gasket kit? with the standard 1.5mm thick head gasket?  Should have waited on that... Sorry

Yup now's the time, and as always be sure to send the top timing cover with the head so that it can be skimmed along with the head.

Looks kinda fishy right there, exhaust manifold may be cracked, pretty common.

Yeah, since it had a cutting ring head gasket on it at some point, and now

some erosion between the cylinders, it's going to need a 

clean- up cut at the very least.

 

So measuring for warpage is next, since if it's badly warped, it's not worth

going any farther.  If you have a machinist, they'll do it best.  You CAN 

check it yourself with a proper straightedge, but it needs to be a good 

straightedge....

You also need to measure thickness. 

If it's already cut to 128, AND it's warped, it's time to go shopping.

 

Sounds like a lot of work, but if you don't,  the engine won't seal again...

Thanks all. As John noted above, yes there’s a local shop, and actually did the block and head on the last build.

I'm sorry that it wasn't something bent or broken. At least you have an answer. This makes me wonder what I will find when I pull my head to get done.  

 

Please let us know how it goes.

Cutting Ring Head Gaskets:  If you like the gasket part of a particular brand or kind of cutting ring head gasket, the cutting ring can easily be removed with needle pliers, a little twist, and a tug; total, ~5 sec/ring.  The final ID might just be what one needs, depending on the situation, bore, etc.

Got the head back from the shop this afternoon.  I'm returning the standard thickness head gasket I'd ordered, but I'm not sure what to order?  The shop said they took three thousandths off the bottom.  The brand that blew was a Victor Reinz.  I'm inclined not to go with that brand again, though it could have been a random occurrence.  The other option is Elring in a 1.8mm or Cometic, which apparently cost in the 3 digits $$(?!).  

 

Is there a brand that's often recommended?  I found this past conversation and found myself more confused than anything:

So, I sincerely hope your machinist was aware of this.... Definite and defined limits on head thickness.

What exactly is the heads thickness now?  Cant really advise head gaskets until we know.

It seems like when a head gasket blows, it's always between 3 and 4 cylinders.  I think it's an M10 thing and not necessarily the gasket mfr.

I use Elring head gaskets, and CopperCoat both sides, two coats.

Wow, this really spiraled.  Sorry about that, Nick.

It's measuring 128.93, so should be within spec, from what I see above.  Correct me if I'm wrong.  What I don't know is if that calls for a certain thickness of gasket.  Throw your thoughts at me.
