Major C-10 Malfunctions

[skyreep1]

Okay, I have two 1971 C-10's, one with a 350 3 on the column, and one with an automatic 307.

Problems:

350= Oil fouled plugs and major power/torque loss
307= Metal shavings found in transmission pan, when shifted, acts like it's in park

Okay so I have a feeling the 307 requires and all new tranny, probably around $1,000.

Sooo focusing on the other one, what exactly needs to be done to have the truck run right and stop having oil fouled plugs?
I.E. Part kits I need to buy, and replacement procedures. It would be absolutely outstanding if I don't have to take the block out.

I hope you guys can help me out on here, I'm at a loss, fairly broke, and want to have one drivable before summer.

Thanks

Why not put the 307 in place of the 350 while you rebuild it? You will have a truck to drive and plenty of time to save and rebuild the 350 the way you want it.

oil foul and power loss sounds like worn out engine, which requires removal of engine, probabaly it can be bored out with new pistons and rings and have the heads reworked
know you did'nt want to here this but thats what it sounds like to me, but to be sure run compression check first, hope this has helped.......Tom

:/ well that sucks, I was hoping I could just replace the rings and it was the oil that was causin it since it wouldn't be firing properly with oil fouled plugs. It only has 50,000 miles and it's been kept in a shed out of the weather it's whole life, 1 owner, ran since 1971. I would pull the 307 but my fathers company owns that truck and I own the 350 sooo, I would have to pay 2 or so grand for the 307.

It could be valve guide seals too, that is a simple fix. There is a fitting you use to air up the cylinder holding the valve closed while you remove the valve spring and replace the seal. I don't mean to over simplify it, just wanted to let you know there is an alternative you could try. It can be a chore and you will need some special tools to complete the job, but your local autozone or O'Rielly's can probably lend you the tools.

Oil fouled plugs could mean several things. I would do a compression test like mentioned above and just start ruling things out before you jump to conclusions. Maybe try to find a different motor on craigs or something like that for the time being. If your going to rebuild a motor usually youll need to get it machined and a lot of parts you should just replace to make sure it wont wear out right after you finished it. Why not switch the good motor to the good tranny?
