My car has 220,000 miles on it and when im done with my firebird the camaro is getting a major tuneup ie plugs wires cap rotor holley ignition module pcv valve oil change O2 sensor fuel filter the ac delco cleaning stuff for the intake and possibly fix my leakey valve covers. Any ways i have this 5 minute oil flush that is susposto clean out the oil system i am debating on using it i dont know if it will cause any problems to my engine after i use it does any one have any experience with this i dont want to use it then regret using it any information would be great.

 

KNOWING YOUR RIDE at what speed were we at!!!!
Just do exactly as ya said.

I would vote no on the oil flush.

It could remove what's still sealing the engine well & that's not good.
Really your ride is quite decent.
Remember anything ya do/upgrade will swap over to a new 3.4 mill!
I'm gonna be over at my other house much more soon I hope to help ya soon!
Infact I'm arriving there at 9:30AM Sat. to meet hardwood floor person and mow my lawn.
I'm sticking the lawn mower into the back of the Firebird.

 

I read some other posts and decided against it. I ended up getting the 4 leaf springs for the bird im returning the 5 leaf i also got a new crossmember since the th400 wont bolt up to the one for the th350.

 

You'll find me over there later on.
Sunday I go sand my new Firebird nose in Torrance.
Monday I'm over this 5806 Burnet house more often.
You saying you got the spings up there now?
GOOD! I hope these others worked for fitment better.
Yes you do need the other cross member.
