well i finally got the propane running good and took it for a test drive. Well I think I had the timing too far advanced or gor something in the intake because the plug for one cylinder disentegrated and there were a half dozel small metal pebbles in the cylinder.

The head looks okay as does the piston, but the pushrods were bent up pretty good and the cylinder walls look like they have been sandblasted.

It doesn't look like there is blowby through the rings though so i'm wondering if I could run a hone down a couple times to try and smooth things up a little and then ruin as is. No camera so no pictures, but anybody think that will work. The walls aren't terrible but the crosshatching is gone.

"it'll buff out" :finger:

 

[thedave]

thats what i'm trying to find out :banghead:

Not good timing for the trail run doah

Sorry to hear of your problems.

 

[thedave]

thats what the ranger is for, i'll be at the run if I have to walk.

Run your fingernail along it if the scratches catch your fingernail a hone probably won't do it. :rotfl: :rotfl:

 

[thedave]

they don't catch on anything but the surface definately feels rough

 

[Towpro]

throw some new rings in! It will help "break them in" :thumb: :rotfl: :rotfl:

 

[thedave]

a bunch of funny people on the net tonight :finger: Hey rob you got any motors lying around? I may be needing to get one from you

OUCH dave!
timing shouldn't have done it...I'd bet you dropped something inside when you installed it... you should be able to hone it if your compression is still good... later on, just put some new rings in it and call it good..

Hey dave, I still have that 79 f250 down the road for sale, it runs good except for some 2bbl motorcraft carb problems....

Plus you could ditch your 203 and slap on the 205 from it, roll the rear 60 under it and swap over the front spindle and knuckles to go eight lug with bigger brakes!!

just a thought!

Ouch!! sounds like you could hone it, but you are only putting a bandaid on it so you are looking at a rebuild soon.

HAAHAHA - -had to quote that one

You can try the bottle brush(hone) but like kevin said it is just a crappy temporary fix.

 

[muddinmike]

try sand blasting the cylinder walls to smooth them out also, just use a fine grit sand :finger:

 

[JoshH]

ouch dave. Let me know if you need any help working on it. I'll be getting back in tomorrow evening so if you plan on doing anything this weekend to it I can lend a hand.

 

[thedave]

I pulled the thing apart and got the piston out. The cylinder doesn't look too bad so i'm goign to try and clean it up, get a new piston, and put the motor back together. Of course anybody with more engine buildign experience is more than welcoem to drop by and let me know if I am wasting my time.

you have a pm
