2 problems : tapa tapa tapa and sputter sputter pop

i pulled the valve covers and nothing looks broken....

 

Well, either you need a new engine or a family counsler......

 

I had that kind of noise in the 400"SBC I had in my blue truck, for about a year and a half and it ran ok, drove it all over So. Cal. at any speed I felt like. Seems it only did it at a steady speed then went away on acceleration, then after a long while it started becoming a clankataclankata...
So I tore it down and it's got the #3-4 crank journal chewed up to the tune of about of .030" missing from the crank and that's a raggedy measure, not cleaned up.
It's just gonna get a new crank one of these days and go back in the blue truck.
It sounded like a lifter to start with, then pinging, then a rod...
If it's just a dime a dozen SBC, just drive it till it really needs fixin' and slug another one in it. That's what I did*.

*(I'm friggin lucky I didn't throw a rod coming back over the Grapevine from the March Meets!)

 

haha i think i need both

 

my friend did say he noticed a little "rod knock" im not sure what it sounds like so i dont know how long that had been going on.... if i could fix the sputtersputtercoughpopfart i would just drive it until it threw a rod or what ever... it a 400m ford aka a boat anchor i could care less if i lost it... but i cant because it keeps craping out

 

Yours is a relativly cheap and easy fix.

It's the WAAAAAAAAAAAAAA...BANG!, klunk that you really have to worry about!

 

ran a compression check... all cylinders were between 160 and 165 psi... what do i check next?

 

btt

 

btt X2 come on you guys

 

Sounds like it's either too rich or too lean to me, can you smell raw gas ?

 

Have you checked for an air leak? What were the plugs like when they came out?

 

yeah i replaced the vaccumm plug on the back of the carb that had rotted and i replaced the base gasket for the carb... the plugs looked like this

 

i cant smell gas

 

btt now it wont even start

 

wander up the back streets and when you find a big old 60's 4 door beater car, offer to haul it away and then use the engine and stuff in your truck, you'll never regret it

 

ok i replaced the coil and rotor and now its running again... still cant take it over 2k without it stumbling so now i guessing power valve and ideas?

 

i already had the motor and tranny out this summer and i dont intend on doing it again... if i do everythings going onto a stock chassis too.

 

btt... i need help! i need something to get me to school and back...

 

Trade it for a horse, ride the horse till it gets sick, then shoot the horse! In the meen time you saved all this money on gas and you can buy somthing else for $500..... Maybe another horse !

 

btt i need help.... its depressing
