i just bought this car from my bro for $500, i think its the sport. its an 86 5-sp with the nifty bbs wheels. heres what its doing. it is some times hard to start. sometimes fires right up. sometimes it smokes alot of white smoke. sometimes it doesnt smoke. always it misses(the ehaust pops irratically) there are new plugs. it overheats after running for about 15-20 minutes. i put in a new thermostat, that didnt work. the coolant bubbles if you look down the neck when its running. just a bunch of little things that i can figure myself.

what do i have to do to get it to stop overheating? because of the air in the cooling system, i would think that there is air getting into it from the combustion chamber. any help would be great. i want it to be reliable and run great. if there is more info that you guys need to know then just ask. i will find out. thanks

 

Your water pump working?

 

i believe it is. how would i check it?

 

bump

 

how many miles on it!!
check all the hoses that have coolant flowing through them and look for puddles of water!! Also does the exaust have a sweet coolant smell to it???
also do a compressioin test on it!!

 

looks like its time to replace those coolent seals and we all know what that means.

 

err avoid cold/short starts... if u can get the car running, just sit there for a bit till the engine goes to med temp and then go... or else u are gonna have a hard time the next time u start up
SOME white smoke is normal...but looks unhealty

 

Coolant seals definately. You get bubbles @ start up down from the filler neck. Exaust is coming up the cooling system.

Erratic popping and idle. Your engine is shot and if it aint you still need to rebuild the engine with the coolant seals popped.

 

thats what i figured, thanks guys
