yea ok just give or take a few thousanths but dont burn off your dick

yeah i looked in and it seems that i have plastic guides but cant determine whether it is or isnt worn. what brought me to the conclusion that it was the timing chain was that the tapping sound would vary in volume. as the rpm would drop as i decelerated it would get a little louder. its kind of a slap mixed with a tap. truck runs perfectly fine just noisy and it bothers me. the valves tap less but the sound doesnt change too much just gets faster as the rpms increase. ima have to go in there and look at it again. how much does that timing chain set go for? if it isnt too expensive im going to change it

Go with engnbldr kits, very resonable price and amazing service. They also come with metal backed guides so it wont break off.

what do you guys think about tightening up the adjustments maybe .1 or .2 more inches?

abecedarian

.1 sounds like a lot
did you mean .001? some people have run at .007 and .011 without issue

joshuapc

aha i gues i forgot the zeros! yeah thats what i meant. i figure the tighter adjutment will compensate for the years of wear. as anyone gone more than .001 like .002 maybe?

joshuapc

well i just readjusted them to a tighter spec and it sounds better. while i was in there i looked down into where my timing chain is and noticed the two grooves that the slacked chain was engraving into the side wall. the guides are plastic and im guessing they're gone. would this be the cause of my slappy tappy engine?!???

raydouble

Yes, definitely.

Time for metal backed guides and a new chain.

annoyingrob

Hurry up before that chain wears completely through the timing cover too. You don't want to deal with what happens when that happens.

raydouble

Or the chain breaks. Neither is a good situation.

yeah ima order the one with the metal guides from engnbldr. im a little pissed that i gotta change it and order it but happy that i finally know the main cause of all that taping!
