So my 2nd opinion went like this and i quote:
funny... they didnt hear a low end knock.. found no oil pressure problems (other than a slight leak) and no valve train noise from bank 2. So with those things and my MAF code and Lean Bank 2 code thats it... im going to chevy tomorrow to ask for my 54 bucks back... It took chevy under 30 mins to "check" my engine. it took the 2nd place 4 and a half hours.. But heres my other curiosity on 10/1/07 i had the water pump opti andwiresreplaced 7,000 miles later they all are having trouble...

 

Id imagine a bad gasket perhaps on the water pump leaking into the opti which probably screwed that up. IM imagining the wires are just for good measure. Sure beats having to replace a whole engine though. Thats good news, thats for sure.

 

yeah. I can do all this work myself piece by piece. I have to take the waterpump off to get to the opti anyway no? As for the wires theres a bunch of oily goop all over em right by the boots and idk if this is normal but theres a small hole bout the size of a bic pen in the bottom of my WP and that seems to be the location of the leak but it looks like oil more than water. idk... Id have to have em fix it between like 11-230 on a wednesday or thursday.. because i worth m-t-f-s and cant have em do it then. I figure on doing the wires myself, not too difficult. not sure if i can do the other stuff without a lift or a fewhours and jack stands.

 

I believe if its leaking from the weep hole that means the pump is nearing death. And im not totally sure what has to come off to get to the opti. I thought it was just having to pull one of the pulleys off that are in front of it to get at it. No clue though. I imagine someone will chime in soon enough

 

my mechanic will do the opti, plugs and wires for 300. cant be much more for the pump. guess it depends on the price of the parts you want to go in. its good things aint as bad as they seemed

 

thats for sure. I cant wait to bring the new results to chevy and ask that they repay me the 54 bucks they stole from me...

 

I don't think you need anything more than basic tools to change the water pump and opti spark and the money you're saving you should go ahead and get the MSD unit and a nice new waterpump. Cool beans though my man, cool beans...

 

yeah. Im gonna go with the AC Delco Water pump, but im not sure if i want to spend 500+ on the MSD opti when i can get Summits Opti for 250 and its basically the same.

 

*cough* TOLD YOU SO *cough* *cough*

 

I just changed my opti and water pump I would highly suggest taking the radiator out makes work a lot faster easier and be sure to get a harmonic puller that has the claws and not the screws
