Dose any one know of a timing gear and chain set that may have used nylon or another type of hard polymer in the make up of the components? I have not found any, and I have checked dozens of listings at this point. The reason for my query is: while doing some prep work for header installation up to and including exhaust crossover block off. I found pieces of hard plastic in the lifter valley (see photo). "IF" there exist a cheap chain and gear set with plastic components, it is feasible that on failure pieces could have ended up in the lifter valley.
I know that more than likely "Bubba" probably dropped something down the intake or carb. While pulling v-covers and intake I was pleasantly surprised with how clean it all looked considering all the other tell-tell signs of someone attempting a craig's list rebuild. On closer inspection it was obvious that someone had been in there recently and clean both the intake, the v-covers, and rocker area. The cam on visual is tired and worn but no scoring. A scope of the cylinders shows basically the same with the exception of #4, raw oil coming from the top down, most likely valve guides. No surprise there. The piston tops are not beat up or dinged. I did spray copious amounts of carb cleaner in both the rocker and lifter valley before discovering the bits of plastic.
Now I'm standing here scratching my *** trying to figure out how far down do I need to go (isn't that a song). I'm thinking maybe a thorough flushing with some cleaning solvent and the pan off might work. Promise the wife I wouldn't tear the car down till the new shop is built. Just want to keep it running and her happy until I'm ready to do the complete rebuild. That will take it off the road for a year easy.
