not sure if this is the right place to post this question, if not im sorry, and feel free to move it

anyways here it goes-

was driving the camaro (89 with a swapped in 358, holley 750, borg warner T5) on the highway around 60mph and heard a loud noise (sounded like it was trying to downshift) i pulled it out of gear and slowed down a bit, put it back into 5th and drove on, and now it sounds like there is an exhaust leak? (just had the headers welded in, bad i know, and new gaskets about 3 weeks ago) also when i pulled over i noticed one of my spark wires popped off the spark plug and was melted all the way through against the header, and i now have a pretty bad coolant leak comming from behind the crankshaft pulley, well actually around what i would call the accessory case, its definetly coolant and leaking bad.... any clue what could be the issue? also when the plug wire melted it fried my battery so just put a new battery in and im splicing together some new 8MM wires right now but dont know where to start on the leak, is there a gasket behind the accesory case that could be bad?

thanks in advance for any help!

 

water pump ? leaking out of the weep hole.

 

hmm, dont THINK that is it, ill try and get a pix in the morning of mine but here is a quick pic i found on google of a SBC, the red arrows and lines are where the leak is comming from

 

Uh, that's not a sbc !

 

well thats what i get for trusting google :P any idea on why it would be leaking coolant from that area tho?

 

I would get a mirror and look at the weep hole under the water pump. the only ares it can leak in that area is the water pump, the water pump bolts , lower radiator hose , or higher from a bypass hose or cracked block.

 

will do, sorry for the long response time, computer got a virus lol just got done reloading windows onto it, should be able to take a look in the morning, good news so far i guess, i dont mind replacing a waterpump at all, been looking at a chrome one on jegs with the chevy bow-tie on it anyway lol good time to upgrade i guess if that turns out to be it, thanks for the help so far!

 

finally got out and took a look, looks like you might be right i hope so anyway lol, it looks like it is leaking from where the waterpump mates up to the block, prolly just the gasket but im going to replace the pump with a nicer looking one, been wanting to for a while and its to rainy / cold out to drive the car for a while anyway, thanks for the help ill let you know if that fixes it

 

use liquid teflon on all four water pump bolts when you go back together.

 

will do, thanks for the tip!

 

ok one more stupid question, how do i tell if my pump is reverse flow or normal? not the best pic and i can get a better one if needed but its raining right now, just pulled this one off facebook lol here is mine, i have all the plug wires out as i am splicing together some new ones while the car is down but if the pics wont help i can have someone turn it over and watch which way it turns, thanks!

 

If that is your pulley setup its the 85-87 standard rotation long water pump.

 

ya the above pic is an older pic of my engine, thanks for the help again! whats the difference between the long water pump and the short? just how far off the block it sits? think the one on jegs i was looking at is a short

 

your correct on the short vs long. make sure the one you get has the mounting tabs for the alt bracket.

 

sorry for being such a n00b lol but does this look like the right one? want to make sure before i purchase it-




heres a link to it- http://www.jegs.com/i/Weiand/925/9240P/10002/-1

 

Looks like it would work too me. it has a duel pattern for the different small block pulley setups. it says not for serpentine witch would indicate its standard rotation. c4 vettes were short reverse rotation with a heater hose outlet.

 

awsome thanks, buying it now

 

ugh my wallet hurts lol! bought that, some new red ignition wires with the bowtie logo on them , some red heat shields for the ignition wires (the fabric ones) the water pump , and a new transmission mount lol cant wait to get it all on

 

finally found some time to go out and work on her, got the old pump out and i am pretty sure it was the problem,all the mounting bolts were VERY loose,and the gaskets are pretty bad, looks to me like it was leaking down into the timing cover and than leaking out the bottom, which is why i thought it was leaking by the CS pulley, have not put the new pump in ran out of daylight but it looks like an exact match so thanks for double checking and looking at it! hope to have it in sometime tomorrow

 

don't forget to run it until the car warms up and the thermostat opens with the radiator cap off too bleed out the air in the system.

 

wouldnt have done that, thanks!

 

Installed this same pump last summer when I caught my stocker leaking from the weep hole. You won't be disappointed.

 

went in perfect thanks need to bring her to the exhaust shop tomorrow to have them fix the leak but you get the point
