1.5 solid 11mm head on 12mm 1.6 block?? carnage pics inside..

that pitting is bad injectors I do believe

[riceatingrabbit]

I have a simular thread to this on vortex... they are saying;


that the pitted pistons are trash, and that I probably have a bent rod... and I probably have flat spots on my bearings..


what do you guys think?



I am thinking of throwing a junkyard head on it and going with it...

[burn_your_money]

Maybe if you had demoed the engine from a mis-shift and reved it to 8000... at cranking speeds I doubt there is any damage to the bottom end. You'd have very deep impressions in the pistons if you bent a rod I would imagine.

Consider the source........

IF the rod bent before the valve and cam broke I don;t think any of these engines would have lasted more than 50K miles.. Same goes for the pistons..   

I have worse looking pistons in my daily driver..  You could almost do shots out of the valve imprints in them...

Throw a head on it with some good injectors!!

[riceatingrabbit]

true...



I got a new head and head gasket stuff for it today... hope to have it running again by the end of the weekend... will keep yall updated

Pistons that looked like these (and the rods that were attached to them) are running just fine for me:




Don't forget to get new nozzles...  

[Smokey Eddy]

i need new nozzles. Can we group buy please .
My pistons too are slightly pitted and have impressions. I dont see how that equates to flat spots on bearings and bent rods.
Vortex just doesn't like Diesel's because we have power house torque monsters and they dont!

Yeah, I came over here to post because I wasn't about to post on the vortex (I am xero over there )

fix the head, slap it on, run it and go.  The damage you have is so minimal it's laughable.

Toasty!!!!

ok, I've run into a snag..

I know that lots of people have put mech heads on  hydro blocks..

but, I have just discovered a major difference between the two, and I need to know what yall are doing about it.

The hydro block/head has two oil ( return?) holes on the front of the engine and the mech one does not..it only has the one in the center..

see the difference in the gaskets:



the block:



and the head I am trying to get on it:




heres how I see it:

the extra hole must be a return hole.. because on the broken hydro head, its just a drain hole.. just like the one in the center but smaller..

so, given that, oil is flowing down... So since the mech head doesn't have the hole, the one in the block will just be blocked and unused.

AM I RIGHT?

with that in mind, I should be able to bolt up the mech head with the mech gasket and be golden.. correct?


but.. I think of another problem: why is the extra hole there on the hydro motor? maybe its because the hydro head is more thirsty for oil, and the block pumps more.. so am I going to be filling the head with oil? and not have adequate draining power? hmmm...

I am really trying to get this sucker running, so, If you have ANY input please post..


THANKS!!!

[riceatingrabbit]

ok.. ever since i made the post about the holes, I have been searching and researching the issue on this site..


I figured out that you can plug it..

I dug around in the garage and came up with a chunk of rubber..

I carved plugs for the head and block that are about 1/2 inch deep and fit VERY tightly into their respective holes..

Then, I coated them in silcone (red RTV) and pounded them in.. Then I used a razor blade and cut them flush to the surface.

I'm also making a rubber plug for the head gasket too.. just for safe measure..


QUESTION:

If you look at my new mech gasket, and compare it to the hydro gasket, you'll notice that around the central oil return hole, there are coolant passages

The mech gasket doesnt have holes for these passages..


Is it OK to drill holes for them in the new gasket?

or should i leave it?

[riceatingrabbit]

ok... ya youre probably right.. I was leaning towards leaving it anyways..


I'm not going to have it running tonight..

I'm running out of time!!

I'm hoping to have the head torqued....

Check out the build thread on my wife's 1.6.  The pistons were much worse than yours, they will be fine. 

Ship that spoiler yet?

do you have a link to that thread?

oh , and yes, it is sent..

check your pm's on vortex..

[riceatingrabbit]

I am VERY close to starting it again...

I am also very nervous about it considering what happened last time..

I have checked and rechecked the cam and IP pump bolts about 6 times already..

and will check again!!!
