rebilt top end now blowN blue smoke

[westroke]

i just rebilt the top end new head gastekt intake gast.. got the heads tested and new springs and valve gides
it starts and idles fine
with 10-30 it will smoke all the time when you leave the lights and a bit at idle
50w oil only smokes when you put you foot into it or running it more than 45min
never loss of coolent
note: it did not smoke befor i had to do the intake gastket

Sounds like they humped up either the guides or forgot to put the "shower Caps" on the Valve stems.

Did they replace the Guides or just knurl the existing?

 

[westroke]

new gides i got the old ones back in a box when the were done
im hoping they did not *&&^ up they were the only place in town that people say are any good

Go back and talk to them.

If they did not put the Valve Caps on, They can Fill the piston with air, pull the Valve spring off and put the Caps on. Head does not need to come off.
New Guides should prevent leak down...not cause it. You didn't have any radical work done to them so I'm guessing it's the Caps.

I hope

with how much work it is to pull the valve covers you might as well pull the dam heads off

With all teh exhaust hardware being fresh, yeah, probably right.

Except aren't the Head bolts "Stretch Bolts" you need new ones?

I'd drive it there and let then see what's going on.

Similar problem on my 4.0, but i did not use new head bolts, what do you mean by stretch bolts?

i had to do this to xeeks motor,thing to note is that the AC box had to come out to get my spring compressor on the back two springs

 

[FORD*FAN]

Thanks jd. I guess I did not do a very good job, (first timer ). going to redo and this time do the valve seals. BTW, injectors are really niosy now any ideas?

 

[jd4242]

You mean rockers

 

[FORD*FAN]

no, injectors for sure. I put new rockers on since the old ones had worn down and making niose. I guess in hinesight prob. should have put new rods in too.

 

[FORD*FAN]

After putting some thought into this. I think I will purchase a rebuilt motor and do a swap.

 

[FORD*FAN]

Maybe I can find someone in Vegas that is good with X's motors.
