alright...so i was doing a valve adjustment..and i was using a pencil to check the travel of the piston to make sure i find TDC. well, after i got TDC i noticed the eraser that was on my pencil was now gone..and nowhere to be found...so im guessing it probably fell into my combustion chamber (UH OH!)....well, being the lazy *** that i am, instead of pulling the head off and retrieving the eraser, i finished the valve adjustment and started it up. i did this assuming since it is rubber it will burn up and desinegrate and leave just some gunky residue. so assuming that i will just run it and then later replace the spark plug, run sea foam through it, and do a compression test to make sure everything is ok. well, i started it up, and it ran fine, no weird noise, no weird smoke. everything was ok.

now im asking you guys, what si the worse that can happen from a eraser being in the combustion chamber? should i be worrying?

 

It's gone. It burned up no issues. Use a screwdriver next time and find TDC on the cam like you are supposed to.

 

i actually got the pencil idea from a post i searched up in the archives posted by P_adams...haha

 

or just use a dowel rod or something thats not going to fall off into the combustion chamber.

 

NOTE:
• Valves should be adjusted only when the cylinder
head temperature is less than 100°F (38°C).
• After adjusting, retorque the crankshaft pulley bolt to
245 N-m (25.0 kgf-m, 181 Ibf-ft).
1. Remove the cylinder head cover.
NOTE: Refer to page 6-53 when installing cylinder
head cover.
2. Set No. 1 piston at TDC. "UP" mark on the camshaft
pulley should be at top, and TDC grooves on the
camshaft pulley should align with cylinder head
surface.
3. Adjust valves on No. 1 cylinder.
4. Loosen the locknut, and turn the adjusting screw
until the feeler gauge slides back and forth with a
slight amount of drag.
5. Tighten the locknut and check clearance again.
Repeat adjustment if necessary.
6. Rotate crankshaft 180° counterclockwise (Camshaft
pulley turns 90°). The "UP" mark should be on the
exhaust side. Adjust valves on No. 3 cylinder.
7. Rotate crankshaft 180° counterclockwise to bring
No. 4 piston to TDC. Both TDC grooves are once
again visible. Adjust valves on No. 4 cylinder.
8. Rotate crankshaft 180° counterclockwise to bring
No. 2 piston to TDC. The "UP" mark should be on
the intake side. Adjust valves on No. 2 cylinder.

 

I think at the temperatures which your combustion takes place, that eraser will be witness to none.

 

hahahaha thats the funniest stuff Ive read in while lol

glad i was able to make you laugh

yea, i was tripping out when it first happened, because i really didnt want to pull the head off. but everything is fine now and i guess its ok. i'll hceck the spark plug for gunk on it and do a compression test just to be sure and then run some sea foam through it.

 

Yea I'm sure you're fine, its just an eraser...its not like it was a rock , screw, bolt, sand or something worse. It was just funny that from what I read it sounded like you were trippin out!

 

hahaha, i was...you shoulda seen me trippin out in my driveway...

 

How about putting everything back together after the fact the eraser was in the cylinder. And remove the spark plug and turn over the motor, it could'of shot out.

well, too late for that now. but i doubt it would've shot out of the tiny spark plug hole and up 4 inches or so. plus i was more afraid of it being stuck between a valve and valve seat possibly causing damage.
