odds of damage?

[mustangracer91]

Just wondering from those that have "been there, done that" often, I'm going to pull my rear failed bank cylinder head, and I know for sure that I've broken off some parts of the valve, as it damaged the spark plug and I can see some small pieces through the spark plug hole, what I'm wondering is are the odds high that the pistons involved are damaged and would need replacement, or do you guys think the damage would be mainly isolated to the valves and cylinder head itself? The reason why I wonder is that it was a cam failure that happened at low rpms (while it was idling in my driveway), and when it happened, it stalled out...the engine never siezed or locked up.

The piston will be damaged. If it is damaged enough to require changing you won't know. You can probably get a used piston cheap enough.

I'm pretty sure I'll need three...just wishful thinking. Can the oil pan and pistons be swapped without pulling the motor?

 

[SHOZ123]

The oil pan can come off while in the car. Pulling the rear head and dealing with the timing chain, while it can be done in the car, is not worth the trouble of not taking out the motor.

If the spark plug was damaged, plan on replacing at a minimum the piston and rod.

Don't try to do it in the car. You'll thank me later.

monkey poo...I've got the money to get the parts, and I could probably get a loan to have the cams welded, but I don't have the necessary hoist to get the engine back in, or the money to pay st louis sho to just fix it for me. grrr...I just wanna drive it again...guess I just need to keep saving up...

You don't need a hoist to pull the engine....

The subframe goes out the bottom.

Set parking brake and a 4X4 across where the flexpipe is at (after disconnecting the Y-Pipe from the flex pipe.

Set the car down after taking of the front tires and use a furniture dolly (I added a steel plate on top of the furniture dolly) Set the subframe down on that. Remove 4 subframe bolts and disconnect all hoses and wiring.

Now with that 4X4 and a floor jack near where the flex pipe is at jack the car up, up, and away until you can wheel the subframe and tranny out from under the car.

Lining the subframe back up as you let the car back down is the "tricky" part.

If you had some simplex jacks that just lift straight up this would be easier, with a floor jack the problem is that the car as it raises moves to the side some, so you are playing that game as you lower the car a bit and move things, then lower the car some more.

Piece of unsolicited advice if I may: We're dealing with 10-20 year old Tauruses here, never borrow a penny for anything with these cars.

Anyway, the most economic route is probably to shop your local recyclers for an engine, install it and get the cams welded.

Alternatively, put it on a truck to NESHO and get a fully welded and re-sealed motor installed for $2500.

I've done it with two floor jacks, jack one side up a little then go to the other side. Repeat as necessary. A good dolly is a must. Don't believe the 1000 lb rating on them furniture dollies. The wheels will give out.

Two sets of jack stands are needed too.

That remains an amazingly good deal.

+1 on the furniture dollies. I have four of them with busted wheels that prove that fact.

In that situation, pallet jacks FTW!

You have a pallet jack in your garage?!
