After putting a new TFI module on i was getting TDC before timing car. I was turning crank with ratchet in other hand i was holding small wood #2 touch up brush to verify piston at top, right as it reached TDC i must of held brush on angle not sure how the F--- it happen i hear snap and pull out snapped brush. Piece is 1 1/4 long and under and 1/8 thick. Ive been vacuuming hole and tried putting rolloed up elec. tape in so far i have not seen or felt piece any ideas? i would appreciate thanks
this is snapped brush and full one next to it for example

after trying for a long time to find it i started to try piston at different heights also with no luck

Head has to come off to make sure you get it all out! Even a small piece can bend a valve. There will be no way to make sure you get it all unless you have access to a bore scope to see how many pieces are actually in there. Good luck.

I had crud fall into the head ports when replacing the lower intake gasket and i taped a 3/8" i.d. rubber fuel line to the shop vac hose and was able to pickup all the gasket crud with that setup. I bet you could then put of vacuum line hose into the 3/8" rubber fuel line, tape that together and stick the vacuum line hose into the spark plug hole and get that thing out of there.

went to harbour freight picked up an inspection camera says right on box for looking into cylinders well dam thing didnt fit thru spark plug hole. Also got a set of stuff that connects to vacuum, put a couple more hours into attemps no good. I might run her a minute without plug in see if anything comes out really at this point i think im F head will have to come off:crying:

When my "homemade":rolleyes: piston stop made of a bolt with a pen:rolleyes: ("to avoid scratch the piston":rolleyes: ) broke inside the chamber through spark plug hole (just the plastic pen) , I used a vacuum cleaner . But later , without sleep , I pulled the head and had some small pieces in the chamber , so I recommend you take out the head .
 
#15 ·
yeah but then again why not just go for it and start her probably just bend a valve at worst, the head will have to come off anyway if she runs right im good?

chuclehead ha ha you should get out more ive seen much worse ya asss clown if you aint got anything helpful then keep your silly comments to yourself:rolleyes:

Wood

I say pump some gas in there and burn it, then burn it some more, and then a few more times, then, as recomended above, stick 3/8 fuel line through the hole and vacume out the ash! Its wood for christ sake, let the MFrrrr burn!
Floating it to the top sounded good to then with a shop vac, vacuum it out. You could burn it out with the piston almost on TDC (so the piece of wood is not crushed) and burn it with a small propane torch.
Also the last plumber I had to use had a scope and a camera and a monitor on his truck, I guarantee that scope will fit in a plug hole.
I would not be pulling a head for something that you can turn to ash!!!!!!!
JUST MY .02
Good luck!

burning it out is starting to sound good!! couple little burn ups should take the fight out of the wood and trust me the Cen-Tech digital inspection camera i got at harbour freight is not goin thru that spark plug hole but it is going back to harbour freight thanks

lol ive been in that hole so many times you are right its wedged dam good!!!

That stick has to be just laying there. The problem is the angle of the spark plug hole and the piston bore. Take your lower intake manifold off, take valve cover off, push as much rope in the spark plug hole as possible, remove the valve spring from the intake valve, the rope will keep the valve from falling into the piston bore, put a clamp on top of the intake valve stem, remove rope and drop valve down low, the clamp will keep the valve from falling in the piston bore and now you have plenty of room to get that stick out.

I doubt that small piece of wood would bend a valve. If your going to try starting it up I bet that piece will just burn up in seconds. My only fear would be if it is stuck between the wall and piston then it may do harm to the rings.

That little piece of wood us no match for combustion internals. It would be smashed, burnt up, and out of the exhaust as ash in about 1.3 seconds. I don't think it would bend a valve either. Valves are far stronger than what you have in there.

I dropped a pencil eraser in a hole once (The metal, rubber,etc). Crossed fingers and started her up. No noises, nothing. Did a compression and leak down check on that cylinder the next day and it had one of the best results.

im praying u are right only because ive been hearing from more than one engine builder that piece of wood is more than enough to hold a valve open for the piston smash into

Well since the Windsor is not an interference engine, and assuming your PTV clearance is still decent, that wood... would probably compress and fracture apart, holding the valve just barely off the seat when the piston top pushes on it.

Keep us updated, but I think you have about a 93.6% chance that nothing will come of it.

Sounds like good odds......

I agree with the tough guys. Just start the thing and call it a day. I'll bet Swinerton's left nut that there's virtually no chance a little scrap of wood will hurt anything in there. On more than one occasion I've seen knuckleheads drop nuts into intake runners and start the thing up. Never has a nut bent a valve. But I have seen a nut embed itself in a piston... which wood will not do.

FWIW, I recently blew a 2" piece of ringland off a piston. No damage to the valves, and the ringland was gone...

8950HO what that is me holding the brush that lost a peice in my engine and another unbroken brush of same size to show the difference how much is in motor. I had to lift and turn dizzy to get to back bolt holding TFI when i did this i forgot to note rotor direction thats why i was getting TDC and then going to time motor.
